TO THE OWNER
The warranty coverage that is extended to your backhoe loader is explained in the Warranty and Limitation of
Liability form. Your dealer will provide you with a copy of the warranty and retain a copy which you have
signed. After you read the warranty, ask your dealer to explain any points that you may not understand.
This backhoe loader was designed to power and propel itself. It is intended to dig, load and move material in
normal and customary applications.
Do not modify or alter or permit anyone else to modify or alter this backhoe loader or any of its components or
any backhoe loader function without first consulting an authorized New Holland dealer. If you have any
questions regarding backhoe loader modifications, contact New Holland North America, Inc., 500 Diller
Ave., New Holland, PA 17557.
Your safety and the safety of those around you depends upon the care and good judgment you use while
operating this equipment. Read the safety precautions carefully.
After you have operated the backhoe loader for 50 hours, take your backhoe loader and this manual to your
selling dealer. He will perform the factory recommended 50-hour service. You will be responsible for the cost
of lubricants, fluids, filters and other items replaced as part of normal maintenance. Prior to taking the
backhoe loader to your selling dealer for service, it is recommended that you contact them to determine any
other charges for which you may be responsible.
All data given in this book is subject to production variations. Dimensions and weights are approximate only

FEDERAL EMISSIONS WARRANTY
New Holland warrants that your new 1998 and later heavy-duty off-road diesel engine was designed, built, and equipped to conform to
applicable U.S. Environmental Protection Agency regulations for a period of use of five years or 3,000 hours of operation, whichever occurs
first.
The new model year, class of diesel engine, and emission application determination for your engine are identified on the emission control
information label affixed to the top of your engine’s rocker arm cover. The warranty period begins on the date the new equipment is sold to the
first retail purchaser.
Any emission control system parts which are proven defective during normal use will be repaired or replaced during the warranty period. The
warranty repairs and service will be performed by any authorized New Holland dealer at the dealer’s place of business, with no charge for parts
or labor (including diagnosis).
As the engine owner, you are responsible to perform all the required maintenance listed in your owner’s manual. New Holland will not deny an
emission warranty claim solely because you have no record of maintenance; however, a claim may be denied if your failure to perform
maintenance resulted in the failure of a warranted part. Receipts covering regular maintenance should be retained in the event of questions
and these receipts should be passed on to each subsequent owner of the engine.
It is recommended replacement parts used for maintenance or repairs be New Holland Service Parts to maintain the quality originally
designed into your emission certified engine. The use of non-New Holland parts does not invalidate the warranty on other components unless
the use of such parts causes damage to warranted parts.
New Holland wishes to assure the emission control systems warranty is being properly administered. If you believe you have not received the
service entitled to under this warranty, you should contact the nearest New Holland Branch Office for assistance. The address and phone
number of each Branch Office is in your vehicle owner’s manual. If additional assistance or information is needed, contact:
Service Department
New Holland North America, Inc.

New Holland, PA 17557
(717) 355-1121
Please note that the Emission Warranty does not cover:
1. Systems and parts that were not first installed on the new equipment or engine as original equipment by New Holland.
2. Part malfunctions caused by abuse, misuse, improper adjustment, modification, alteration, tampering, disconnection, improper or
inadequate maintenance, or use of non-recommended fuels and lubricating oils.
3. Accident caused damage, acts of nature, or other events beyond New Holland’s control.
4. Replacement of expendable items made in connection with scheduled maintenance.
5. Parts requiring replacement, inspection or adjustment maintenance intervals for reasons other than being defective.
6. Parts which are not New Holland Service Parts.
7. Loss of time, inconvenience, loss of use of equipment/engine or commercial loss.
8. Equipment with altered or disconnected hourmeter where the hours cannot be determined.
9. Equipment normally operated outside the United States.
10. Non-defective parts replaced by other than New Holland dealers.

SECTION 1 -- INTRODUCTION
IMPORTANT ECOLOGICAL CONSIDERATIONS
The following are recommendations which may be of
assistance:
Where no legislation exists, obtain information from
suppliers of oils, fuels, antifreeze, cleaning agents,
etc., with regard to their effect on man and nature and
how to safely store, use and dispose of these
substances.
Become acquainted with and ensure that you
understand the relative legislation applicable to your
country.
HELPFUL HINTS
Modern coolant mixtures, i.e. antifreeze and other
additives, should be replaced every two years. They
should not be allowed to get into the soil but should
be collected and disposed of safely.
Avoid filling tanks using cans or inappropriate
pressurized fuel delivery systems which may cause
considerable spillage.
Do not open the Air--Conditioning system yourself.
Your dealer or air conditioning specialist has a special
equipment for discharging and charging the system.
In general, avoid skin contact with all fuels, oils,
acids, solvents, etc. Most of them contain
substances which can be harmful to your health.
Repair any leaks or defects in the engine cooling or
hydraulic system immediately.
Modern oils contain additives. Do not burn
contaminated fuels and/or waste oils in ordinary
heating systems.
Do not increase the pressure in a pressurized circuit
as this may lead to a catastrophic failure of the
system components.
Avoid spillage when draining off used engine coolant
mixtures, engine, gearbox and hydraulic oils, brake
fluids, etc. Do not mix drained brake fluids or fuels
with lubricants. Store them safely until they can be
disposed of in a proper way to comply with local
legislation and available resources.
Protect hoses during welding as penetrating weld
splatter may burn a hole or weaken them, causing
the loss of oils, coolant, etc.

SECTION 1 -- INTRODUCTION
SAFETY PRECAUTIONS
A careful operator is the best operator. Most accidents can be avoided by observing certain precautions. To help
prevent accidents read and take the following precautions before operating the machine. Equipment should be
operated only by those who are responsible and instructed to do so.
IMPORTANT: In this manual references are made to positions of switches and components as located to the
Left Hand and Right Hand side of the machine. In most situations the position described is when the operator
is seated on the machine and looking forward, unless otherwise stated.
THE BACKHOE LOADER
Ensure attached or trailed equipment is operated
and maintained in accordance with the
instructions issued by the equipment or accessory
manufacturer.
IMPORTANT: Never leave the machine with the
loader or backhoe raised, always lower the loader
and backhoe to the ground when not in use. Unless
the loader support and Backhoe transport lock are
engaged.
4. With the machine operational always use the seat
belt.
1. Do not allow anyone to operate the machine
without proper instruction. Legislation in many
countries requires that all operators be instructed
on the proper procedures and operation of the

SAFETY CAB OR ROPS
ROPS MAINTENANCE AND INSPECTION
Your machine is equipped with a Safety Cab or ROPS
and it must be maintained in a serviceable condition.
DAMAGE TO THE ROPS
NOTE: The following statements are for your own
protection as well as other people
If the tractor has rolled over or the ROPS has been
damaged (such as striking an overhead object during
transport), the ROPS must be replaced to provide the
original amount of protection.
1. Do not modify, drill or alter the Safety Cab or
ROPS frame in any ways as doing so could render
you liable to legal prosecution.
After an accident, check for damage to the ROPS,
operator’s seat, seat belt and seat belt mountings.
Before you operate the tractor, replace all damaged
parts.
2. Do not attempt to straighten or weld any part of the
frame or retaining brackets which have suffered
damage. By doing so you may weaken the
structure and endanger your safety.
DO NOT TRY TO WELD OR STRAIGHTEN THE
ROPS.
WARNING
Never attach chains, ropes, or cables to the ROPS
or Cab for pulling purposes; this may cause the
tractor to tip backward. Be careful when driving
through door opening or under low overhead objects. Make sure there is sufficient overhead clearance for the roll bar
3. Do not secure any parts on the safety cab or
ROPS frame with other than the special high
tensile bolts and nuts specified.
4. Do not attach chains or ropes to the cab or ROPS
frame for pulling purposes.
WARNING
5. Do not take unnecessary risks even though your
safety cab or ROPS frame affords you the
maximum protection possible.
If the ROPS is removed or replaced, make certain
that the proper hardware is used and the recommended torque values are applied to the attaching
bolts.
ROLL OVER PROTECTION STRUCTURES
WARNING
A roll over protective structure (ROPS) and seat belt
were standard equipment for the tractor at time of
factory assembly. The seat belt, when used by the
operator, maximizes the protection offered by the
ROPS. ALWAYS use your seat belt with the ROPS -seat belts save lives when they are used.
Always wear your seat belt when the tractor is
equipped with a ROPS.

SECTION 2 -- CONTROLS AND OPERATION
CAB CLIMATE CONTROLS
Heater Blower Control, Figure 30
A three speed blower is installed for air movement
around the cab and is controlled by switch (1) mounted
in the instrument console to your right. Turn the switch
clockwise to the first position for slow speed. Further
rotation of the switch in a clockwise direction selects
medium and fast speeds.
NOTE: With the window and doors closed, the blower
may be used to pressurize the cab to exclude dust.
Heater Temperature Control
The temperature of the air from the heater is adjusted
using the control knob (2). Turn the control clockwise
to increase the temperature of air from the heater and
counter clockwise to reduce the temperature.
WARNING
The cab air filters are designed to remove dust from
the air but may not exclude chemical vapor. When
working in an enclosed area ensure there is adequate
ventilation as exhaust fumes can suffocate you.
AIR CONDITIONING SYSTEM
(WHERE FITTED), Figure 31.
The optional air conditioning system improves the
comfort and health of the operator by controlling
temperature, humidity and circulation of air within the
cab.
Heat reduction is controlled by circulating the air
through the cooling unit (evaporator). This unit also
serves to reduce the moisture and dirt content of the
air, as the wet surface of the evaporator collects dust
and pollen particles which drain off the condensed
moisture.
The system consists of two heat exchangers and a
compressor inter--connected by tubing. The cooling unit
(evaporator), is located in the seat pod with the second
heat exchanger (condenser), mounted in front of the
engine radiator.
A special refrigerant R--134A that is easily heated and
cooled, is circulated through the two heat exchangers
by the pump (compressor). This is mounted to the
side at the front of the engine rocker cover, and driven
by a ‘V’ belt from the crankshaft pulley.
IMPORTANT: R--134A is the only refrigerant
acceptable for your machine Air Conditioning system.
2--26

SECTION 2 -- CONTROLS AND OPERATION
Operation
To operate push the button (1) IN, which will engage
the air conditioning compressor
A three speed blower is used for the air circulation
and operates by turning the switch (2) Figure 31,
mounted to the right of the operator seat.
1st Position -- Low Speed
2nd Position -- Medium Speed
3rd Position -- Fast Speed
The air--conditioner filter is located on the left hand
side of the seat pod and should be serviced as
outlined in the Section 4.
31
WARNING
The air filter is designed to remove dust from the air
but may not exclude chemical vapor. Refer to
chemical manufacturers directions regarding
protection from dangerous chemicals.
Air Recirculation
Four air flow vents are located on the left side of the
seat base. When open, a portion of the air flow will
recirculate through the evaporator. When closed, all
air will be drawn from outside the cab. To open or
close a vent, press one side of the disc.
Air recirculation is recommended in conditions of high
ambient temperature or humidity to reduce the load
on the air conditioning system by passing already
cooled and dehumidified air over the evaporator.
IMPORTANT: The air--conditioning can be operated
with the cab heater on to eliminate moisture on a
damp morning, but this action will not cool the cab.
Too cool the cab on a hot day ensure the cab heater
is turned off.
SM50006
32
If the machine has been parked in the sun, quicken
the cooling by operating the air--conditioning for 2--3
minutes at its coldest setting. Set maximum blower
speed with a window left partially open to force most
of the warm air from the cab.
With the air cooled sufficiently, close the window and
adjust the controls to the desired temperature. To
ensure proper operation of the system be sure the
cab filter is regularly serviced. Refer to maintenance
Section 4.
2--27
33
SECTION 2 -- CONTROLS AND OPERATION
It is the normal function of the air--conditioner to
extract water from the air. As such it is possible pools
of water will collect beneath the drain hose outlets
under the cab when the machine is stationary.
IMPORTANT: Prior to seasonal operation of the air
conditioner it is essential you close the heater knob fully
OFF.
REFRIGERANT R--134A
WARNING
R--134A can be dangerous if improperly handled.
Therefore it is important the following warning and
directions are adhered to.
R--134A has a boiling point of 10°F (--12°C).
Never expose any part of the air--conditioner system
to flame or excessive heat because of risk of fire or
explosion, and the production of phosgene gas.
Never disconnect or disassemble any part of the
air--conditioning system as escaping refrigerant can
cause frostbite.
WARNING
If refrigerant should contact the skin use the same
treatment as for frostbite.
Warm the area with your hand or lukewarm water
90°F (32°C), cover the area loosely with a bandage
to protect affected area against infection and consult
a doctor immediately.
If refrigerant should contact the eyes wash
immediately in cold clean water for at least 5 minutes
and consult a doctor immediately.

SECTION 2 -- CONTROLS AND OPERATION
Air Flow Vents, Figure 34.
Air flow vents are conveniently positioned in the cab
and may be independently adjusted, as required, to
direct warm or cold air onto the windscreen and side
windows or to the cab interior as required.
Each vent may be swivelled and adjusted to control
the flow of air.
To open a vent, press one side of the disc and turn it,
as required, to direct the air flow.

SECTION 2 -- CONTROLS AND OPERATION
ALL WHEEL STEER
These machines are equipped with two steering
axles that provide normal steering (front wheels
only), all wheel steer, and crab steer.
The steering mode is determined by the three
position selector switch on the front console.
Position 1 = Normal Steering (front wheels only)
Position 2 = All Wheel Steer (front and rear wheels
turn in the opposite directions)
Position 3 = Crab Steer (front and rear wheels turn in
the same direction)
Steering Selection
To select the desired steering position slow the
machine to a stop and turn the switch to position 1, 2,
or 3. If both front and rear wheels are in the straight
ahead position the selection will be completed and
the indicator light in the front panel (two wheel drive
position only) and the appropriate steering mode
indicator light in the side panel will light confirming the
selection. The light(s) will remain on until another
steering mode is selected. If the front and rear wheels
are not in the straight ahead position when the
steering selection is made the indicator light in the
mode selected will blink and the steering mode will
remain ulnchanged until the steering wheel is slowly
turned through the straight ahead position. When the
straight ahead position of the front and rear wheels is
reached the steering mode change will be granted
and the indicator light will come on steady. In certain
instances it may be necessary to slowly turn the
wheels to full lock left and full lock right to allow the
steering system to self calibrate and engage the
desired steering mode.
WARNING
Before driving on the highway engage the Normal
(front wheels only) steering position. Highway
travel in the All Wheel or Crab steering positions
may reduce machine stability in sharp turns or
create unexpected machine movements.

DRIVING WITH POWERSHIFT
Selecting Neutral
At power up, ‘‘NEUTRAL and 2nd Gear’’ are
automatically selected regardless of the power shift
lever position (1). The LED 2 and the N--LED are
illuminated RED, (neutral 2nd), the microprocessor
is in a neutral lock state.
If after driving, neutral is selected and the shift lever
stays in neutral for more than 3 seconds the
microprocessor automatically defaults to the neutral
lock state for safety.
NOTE: In neutral an automatic shift routine takes
effect to prevent damage to the transmission due to
overspeeding.
77
Leaving Neutral
A feature of the power shift lever is the NEUTRAL
LOCK STATE, which does not allow forward or
reverse direction drive to be selected. This feature
prevents the vehicle accidently moving should the
lever be knocked into forward or reverse. To leave
the neutral lock state, you select drive direction
followed by an upshift by rotating the shift lever.
Selecting Forward
To select forward travel push the lever away from you
and the LED will illuminate green.
NOTE: When forward is selected you will not be
given any indication of gear selected, only the
maximum selected gear the transmission will shift
too. The microprocessor is programmed to be an
automatic speed based shift system.
In addition whether forward actually engages at that
time, depends on the status of the vehicle, for
example if on the move, road speed and direction will
be considered by the microprocessor before any
shift changes take place.
78
Selecting Reverse
To select reverse travel pull the lever towards you
and the reverse LED will illuminate orange.
NOTE: When reverse is selected you will not be
given any indication of gear selected, only the
maximum selected gear the transmission will shift
too. The microprocessor is programmed to be an
automatic speed based shift system.
In addition whether reverse actually engages at that
time, depends on the status of the vehicle, that is if
on the move road speed and direction will be
considered by the microprocessor.
79
2--50
SECTION 2 -- CONTROLS AND OPERATION
Up Shifting
Up shifting to a desired gear from neutral is achieved
by twisting the handgrip counter clockwise (+) in
single movements, If held in this position the
processor will advance the shift selection from 2
though to 4 in 1.8 sec intervals.
NOTE: An upshift request after a downshift is
delayed for 2 seconds. Should an error occur with the
speed sensor the microprocessor will not allow up
shifts above 2nd gear and will be indicated by the ‘T’
LED flashing and the ‘N’ LED flashing slower.
80
NOTE: If ascending up a steep inline select 2nd and
proceed, if speed and power allow upshift onto 3rd
and 4th
Down Shifting
WARNING
If descending down a steep incline select 2nd and
proceed, upshifting only when safe to do so. YOU
CAN NOT DOWNSHIFT TO REDUCE SPEED IF
THE VEHICLE SPEED IS ABOVE 15 km/h (9 mph)
Downshifting to the desired gear is achieved by
twisting the handgrip clockwise (--) in single
movements, If held in this position the processor will
decrease the shift from 4, if the shift lever was in this
gear, though to 1 in 1.5 sec intervals.
81
NOTE: If the gear requested and the shift attainable
are not the same because of torque convertor turbine
RPM being too high, the gear position LED(e.g. LED
4) will flash and the shift lever position will illuminate,
not flashing, (e.g. LED 2), until the requested gear is
reached. When a gear position LED is flashing this
indicates that the vehicle has to reduce speed to
reach the requested gear.
Direction Changes
Changing driving direction is achieved simply by
shuttling the power shift lever between forward and
reverse and vice versa which is allowed at any time.
The system response however depends on vehicle
speed and currently engaged gear. When driving in
1st or 2nd gear direction changes are unrestricted
and are granted immediately.

RESPONSE 1: If the vehicle speed in forward is
above 15 km/h (9 m/h) and reverse is selected
downshift engages but momentum forward remains,
until the speed drops sufficiently to allow downshift
to take place when reverse is achieved in 2nd gear.
RESPONSE 2: If the vehicle speed in forward is less
than 15 km/h (9 mph) reverse takes place
immediately into 2nd gear.

Should a speed sensor fault be detected while in F3
or F4 a downshift sequence to 2nd gear will take
place and is indicated by the LED ‘T’ flashing fast and
the LED ‘N’ flashing slowly.

Transmission Power Shifting
In the previous paragraphs shift changes have been
shown as precise movements and twist actions of
the power shift lever. However the transmission can
change gear automatically in forward or reverse as
described in the following paragraph:
Select forward and 4th gear on the power shift lever
and with the handbrake released apply pressure to
the foot accelerator. As the engine revs and vehicle
speed increase the transmission will start from 2nd
gear and change up through 3rd and 4th gears up to
maximum road speed.
When you require to slow down or stop release the
foot accelerator and apply the footbrake, the
transmission will automatically downshift through
4th, 3rd and 2nd gear as the vehicle speed
decreases.
84
2--52
SECTION 2 -- CONTROLS AND OPERATION
Kick Down, Figure 85
The kick down facility (2nd to 1st gear only) on this
transmission increases torque instantly to the driving
wheels and hence pushing power. For example
when the loader is pushing into a pile and more
torque is required at the wheels.
This is achieved by the instant gear change from 2nd
to 1st by the use of the button (1) without the need
to use the twist grip on the power shift lever.
NOTE: The kick down facility is only available when
the transmission is in 2nd gear and the kickdown
button (1) is depressed. If kick down can not be
achieved (Vehicle speed too high) the LED 1 will be
illuminated and LED 2 will be flashing.
85
Transmission Disconnect, Figure 86
The disconnect feature is useful when loading, for
example; when pushing the loader into a pile and you
have sufficient dirt in the bucket press the disconnect
switch which disengages the transmission. This
allows the full power of the engine to be directed to
the hydraulic oil pump. Disconnect is available in 1st,
2nd and 3rd gears.
NOTE: Transmission disconnect is selectable, when
the vehicle speed is less than 5 km/h (3 mph) by
depressing the button on the loader lever and remains
active until the pedals or switch are released.
Speed Ranges
86
The microprocessor controlling the power shift
transmission is pre programmed to control the speed
at which the gear changes take place.
This effectively protects the transmission from
excess forces, should gear changes be selected at
higher speeds than is desirable.

SECTION 2 -- CONTROLS AND OPERATION
COLD WEATHER STARTING, DOWN TO
--18°C (0°F)
Thermostart
Your machine is equipped with a Thermostart cold
weather starting aid which is effective in temperatures
down to --18°C (0°F).
The Thermostart will ignite fuel in the manifold and
heats indrawn air, prior to it entering the combustion
chamber.
WARNING
Do not use “ETHER” with the Thermostart. If in an
emergency, it is necessary to use a starting aid with
thermostart installed, disconnect the terminal wire
from the thermostart on the intake manifold and
insulate the free end of the wire. The thermostart is
at the rear of the inlet manifold.
In Cold Weather With The Engine Cold:
D When starting a cold engine at temperatures
below 4°C (40°F) open the throttle fully. Turn the
key--start switch to position (II) and hold in this
position for 15 seconds, during which time the
thermostart warning light will be illuminated. After
15 seconds turn the keystart switch fully
clockwise to position (III) and start the engine.
D If the engine fails to start after a maximum of 60
seconds of cranking repeat the starting
procedure. Do not operate the starting motor for
more than 60 seconds.

SECTION 2 -- CONTROLS AND OPERATION
COOLANT IMMERSION HEATER FOR
COLD WEATHER STARTING BELOW
--18°C (0°F) (where fitted)
STARTING THE MACHINE WITH JUMP
LEADS
WARNING
If temperatures colder than --18°C (0°F) are
encountered, a coolant immersion heater is available
as an accessory. The coolant immersion heater is
effective to --29°C (--20°F) when used in conjunction
with the Thermostart.
This dealer installed accessory consists of a heating
element fitted into the core plug apertures on the
right--hand side of the engine block. The heater
operates on 115 volts or 230 volts AC. (dependent on
type fitted), and provides easier starting down to --29°C
(--20°F).
Operate the starting motor only from the operator’s
seat. If the neutral start switch is by--passed the
engine may be started inadvertently with the
transmission in gear.
Wear eye protection when charging the battery or
starting the machine engine with a slave battery.
If it is necessary to use jump leads from an external
battery to start the machine, proceed as follows:
D Connect one end of the jump lead to the machine
12 volt battery positive (+) terminal and the other
to the auxiliary 12 volt battery positive (+)
terminal.
D Connect one end of the second jump lead to the
auxiliary 12 volt battery negative (--) terminal and
the other end to the machine engine block, following
this procedure will prevent sparks occurring near
the batteries. Follow the starting procedure
previously described.
WARNING
To avoid shocks or other injuries, never use an
ungrounded or inadequate extension cord. Always
use a grounded 3 wire extension cord with a 3 wire
plug which is rated for at least a 15 ampere load.
NOTE: When using a slave battery to start the engine
ensure that the polarity is correct otherwise the
alternator may be damaged.
To operate the heater connect the heater plug to a
suitable extension lead and switch on for two hours
before carrying out the cold weather starting
procedure.
NOTE: The heater may be left switched on for more
than two hours without harm. However, no noticeable
increase in the heater’s effectiveness will be achieved
after this period of time.
2--60
D When the engine starts allow it to run at idle speed,
turn on all electrical equipment (lights, etc.) then
disconnect the jump leads in reverse order to the
connecting procedure. This will help protect the
alternator from damage due to extreme load
changes.
NOTE: Your machine has an electro--magnetic fuel
shut--off, it is therefore not possible to operate the
machine without a battery installed. The machine will
shut down when the power supply to the fuel shut--off
solenoid is disconnected (battery removed).
SECTION 2 -- CONTROLS AND OPERATION
STOPPING THE ENGINE
NOTE: Turbocharged engines only -- Before
stopping, idle the engine at 1000 rev/min for
approximately two minutes. This will allow the
turbocharger and manifold to cool and prevent
possible distortion of components.
To stop the engine carry out the following procedure:
D Close the throttle.
D Apply the parking brake.
D Power Shift: Place the power shift lever into
‘‘NEUTRAL’’.
D Lower the loader and backhoe to the ground unless
locked in the transport position.
D Turn the key--start/stop switch to the ‘‘OFF’’
position.
Avoid prolonged operation at either high or low engine
speeds without a load on the engine.
Avoid overloading the engine. Operating in too high
a gear under heavy load may cause excessive engine
overloading. Overloading occurs when the engine will
not respond to a throttle increase.
Use the lower gear ratios when moving heavy loads
and avoid continuous operation at constant engine
speeds. Operating the machine in too low a gear with
a light load and high engine speed will waste fuel. You
will save fuel and minimize engine wear by selecting
the correct gear ratio for each particular operation.
Check the instruments frequently and keep the
radiator and oil reservoirs filled to the recommended
levels, see Section 4, of this manual for details.
WARNING
Check the area beneath the equipment to ensure
that no injury or damage will be caused when the
equipment is lowered.
RUNNING--IN PROCEDURE
Your new machine will provide long and dependable
service if given proper care during the 50--hour
running--in period and serviced at the recommended
intervals.
To ensure adequate lubrication, idle the engine at
1000 rev/min. for one minute before placing a load on
the engine. Do not race the engine during the one
minute warm--up period.
After the engine has warmed sufficiently, cycle the
loader or backhoe cylinders several times to warm
the hydraulic system oil.
Daily checks during running--in include:
D Radiator coolant level
D Engine oil level
D Hydraulic system oil level
D Transmission oil level
D Rear axle oil level
D Loader and backhoe lubrication fittings
D Engine air cleaner restriction indicator light
D Rear wheel nuts for tightness
D Front axle hub oil level (four wheel drive)

WARNING
Study the safety precautions before operating the
loader. Ensure that you are thoroughly familiar with
the loader operating techniques before attempting
to operate.
IMPORTANT: To achieve optimum performance
operate the loader at rated engine speed only.
A single loader control lever (1), controls the lowering
and raising of the loader lift arms, the roll--back and
dumping of the bucket and the opening and closing
of the multi--purpose bucket, when fitted. In addition
to these movements a ‘‘float’’ and a ‘‘return to dig’’
position may be obtained.
96
The ‘‘float’’ position enables the loader lift arms and
bucket to follow the contour of the ground and is
obtained by moving the loader control lever forward
into the detent position. The lever will remain in the
‘‘float’’ position until it is moved manually towards
neutral.
The transmission disconnect switch (2) disconnects
drive to the transmission for increased power and
loader control.

SECTION 2 -- CONTROLS AND OPERATION
Return To Dig Sensor, Figure’s 101 and
102.
1
Return to dig is an electrically activated feature which
enables the operator to automatically return the
bucket to a level digging position for a further work
cycle with one simple movement of the loader control
lever (3).
The return to dig system consists of an electromagnet
mounted on the bucket spool, a sensor (1) mounted
on the cylinder barrel and an indicator rod mounted
on the cylinder rod end.
Whenever the bucket is rolled forward to dump the
return to dig electrical circuit is completed and the
solenoid on the bucket spool is energized.
When the loader bucket control lever (3) is moved
diagonally left to the return to dig position (4) the
electromagnet will hold the bucket spool in the roll
back position until the bucket is in the level digging
position at which time the indicator on the rod of the
bucket linkage will pass in front of the sensor which
de--energizes the electromagnet on the bucket spool
enabling the spool to return to the neutral position.

Adjustment of the return to dig sensor is as follows
1. Place the bucket on the ground in the preferred
digging position.
2. Check the dimensions of 88.5 mm (3.5I) and
7.5 mm (0.3I) are maintained as shown.
3. Ensure the face of the sensor (1) is 6 mm (0.24I)
from the rod (2).
As a visual aid for the operator, while seated in the
cab, the pointer mounted on the loader arm can be

Position the loader bucket on the ground fully rolled
forward prior to removal. Remove the pivot pin
securing bolts and drive out the pivot pins.
WARNING
When it is necessary to remove pins from the
loader that require a hammer and drift use only a
brass hammer and brass drift and wear safety
glasses.
Inspect all bushings for dirt and foreign matter and
clean before installing the pivot pins. Installation of a
bucket follows the removal procedure in reverse.
Machines with a ‘‘multi--purpose’’ bucket installed, it
is necessary to disconnect and plug the hydraulic
hoses prior to loader bucket removal.
WARNING
To avoid personal injury, shut off the engine, relieve
all hydraulic pressure before any hydraulic
connection is disconnected.

SECTION 2 -- CONTROLS AND OPERATION
QUICK RELEASE LOADER BUCKET
MANUAL COUPLING, (WHERE FITTED),
Figure 105.
A Loader Bucket Quick Release mechanical coupling
(1) can be fitted between the loader bucket and loader
arms, by means of the existing bucket retaining pins
(2) as with normal bucket attachment. Refer to the
manufacturer’s operating instruction’s for full
information.
To connect the coupling to the bucket, roll the
coupling forward as if to dump and position the top
jaws (3) into the bucket top lift pins (4). Roll back the
coupling and the bucket will lift but keep at ground
level. Use additional retaining pins in position (4) as
you would for normal bucket attachment.
IMPORTANT: Ensure the loader bucket and all
attaching pins and lynch pins are secure before
operating the loader.
Changeover of attachments is the reverse
procedure, lower the bucket to the ground, remove
the bucket retaining pins (4) roll out the coupling as
is if to dump and the bucket will be released.
105
WARNING
If in any doubt about fitting or adjustments, consult
your local authorized dealer.
WEIGHTING, Figure 106
Your machine may be operated without a backhoe in
which case four counterweights (1), each weighing
453.6 kg (1000 lbs) must be mounted on the rear of
the machine to provide stability during loader
operations.
WARNING
Do not operate the loader with the backhoe
removed unless rear counterweights are installed.
106
2--67
SECTION 2 -- CONTROLS AND OPERATION
LOADER ARM SUPPORT,
This machine is equipped with a loader arm support,
which is stored on the left--hand loader arm and
retained in position by a pin .
WARNING
To avoid personal injury never work beneath or
around an unsupported loader. Always install the
loader arm support.
Remove the support from the cylinder and raise the
loader to full height remove the strap (3) position the
support onto the loader lift cylinder. Slowly lower the
loader until the support takes the weight of the loader
and fit the retaining strap (3). Do not apply down
pressure on the loader lift cylinders.
To remove the support remove the strap, raise the
loader to full height then lift and position the support
onto the loader arm. Retain the support to the loader
arm with the retaining pin then lower the loader to the
ground.
LOADING OPERATIONS
IMPORTANT: Do not operate the loader without the
bucket installed. Operation of the loader without
bucket installed can result in the bucket links catching
under the loader arms causing damage to the
cylinders and linkage.
Suggested operating techniques for loader operation
are outlined in this section. Practice the lever
movements as you operate the loader to increase
operating efficiency.
IMPORTANT: Before operating in temperatures
below --1°C (30°F) operate the engine for
approximately 15 minutes at speeds below 1200
rev/min. to warm the oil to the normal operating
temperature.
Operate the loader with the engine running at
1200--1700 revs/min. Good production will result at
this speed and will reduce bucket spillage and
unnecessary component strain.
2--68
107
108
SECTION 2 -- CONTROLS AND OPERATION
To fill the bucket from a stock pile, Figure 109, set the
bucket in the level position and lower the arms with
the loader lever in the full forward ‘‘float’’ position.
109
As the loader enters the pile, Figure 110, depress the
transmission disconnect switch ease the loader lever
rearwards and to the left to lift and roll back the
bucket.
Lift and roll--back of the bucket will increase efficiency
as a level bucket throughout the lifting cycle resists
bucket lift and increases break away effort.
NOTE: Do not be concerned if the bucket is not
completely filled during each pass. Maximum
productivity is determined by the amount of material
loaded in a given period of time. Time is lost if two or
more attempts are made to fill the bucket on each
pass.
110
Fully roll back the bucket and lift the loader arms,
Figure 111, then release the transmission disconnect
switch. keep the loaded bucket as low as possible,
especially when operating on a slope or over rough
ground.
WARNING
When operating on a hill or slope,keep the bucket
as low as possible. This keeps the bucket centre of
gravity as low as possible, giving maximum
stability.
When transporting the load, keep the bucket as low
as possible to resist tipping, in case a wheel drops
in a rut.
111
2--69
SECTION 2 -- CONTROLS AND OPERATION
Raise the loader high enough, Figure 112, to clear
any obstruction (1) prior to dumping the load.
After the bucket is dumped, back away whilst
lowering and levelling the bucket using the return to
dig facility if required.
During hard surface operation, place the loader lever
in ‘‘float’’ (full forward held by the detent), and keep
the bucket level. This will permit the bucket to ‘‘float’’
on the contour of the working surface. If hydraulic
down pressure is exerted, the bucket will wear faster
than normal.
112
The ‘‘float’’ position will prevent the mixing of surface
material with stockpile material. It will also reduce the
chance of surface gouging when removing snow or
other material.
When loading from a bank select the highest forward
gear which will provide the most efficient loading
operation without going into a ‘‘stall’’. Keep the
working area free of ruts and holes occasionally back
grading with the bucket using the heel or low rear
edge of the bucket.
WARNING
To avoid personal injury exercise care when
undercutting high banks. Soil slides can be
dangerous. Load from the bank as low as possible
for maximum efficiency. Remember that loader lift
and breakaway capacities diminish rapidly as
loading height is increased.
For site stripping peeling or scraping, Figure 113, use
down pressure with the loader lever in the lowered
position, and a slight bucket angle to start the cut.
Begin the cut at the notch approximately 50mm (2 in)
deep and hold the depth by feathering the bucket to
adjust the cutting lip up or down as required. When
the machine front tires enter the cut, adjust the lift
arms to maintain the correct depth. Make additional
cuts until the desired depth is reached.
Back grade the working area occasionally with the
bucket flat and slight down pressure to keep the
working area smooth and free from ruts or holes.
If the loader lever is moved for lift cylinder action
without controlling the bucket angle, the bucket may
gouge and leave a series of ruts in the surface.
2--70
113
SECTION 2 -- CONTROLS AND OPERATION
To backfill a trench efficiently it is necessary to move
the maximum amount of soil without losing speed of
‘‘stalling’’. If a ‘‘stall’’ occurs downshift or reduce the
depth of cut. If the machine is not working at capacity
in the gear selected, increase the depth of cut.
Operate at right angles to the trench with the loader
bucket level. Leave the soil in the bucket as emptying
the bucket on each pass is time--consuming, and
leave soil that drifts over the side of the bucket for the
final clean up. One lengthwise clean up is usually
sufficient to gain an acceptable grade after
backfilling.
When backfilling from a large pile, shovel off the top
of the pile, pushing toward the excavation. Drag some
soil rearward to form a work ramp of convenient
grade.
If during the backfill operation the machine front
wheels get stuck in a trench dump the bucket and
apply down pressure to lift the front wheels from the
trench. Actuate the bucket as engine power is applied
to move the machine rearwards.
NOTE: Maximum bucket down pressure may be
obtained by ‘‘feathering’’ the loader lever to the right.
IMPORTANT: The Safe Working Load of the loader
is calculated using a standard bucket, therefore,
when using any other bucket or attachment for
‘‘lifting’’ or ‘‘craning’’ the weight of the bucket or
attachment must be taken into account when
calculating the rated load of the loader, Figure 114.
114
Safe Working Load
LB 115 =
+kgs
1000 kgs (2204lbs)
The loader may be used for lifting applications by
attaching a chain to the hook on the bucket (where
fitted).
WARNING
If ‘craning’ of objects is to be performed a suitable
(Hose Burst Check Valve) must be fitted in the
loader circuit. If craning is performed without a
check valve fitted, a hose failure and subsequent
dropping of the loader to the ground could cause
serious injury to you or bystanders.

SECTION 2 -- CONTROLS AND OPERATION
HYDRAULICALLY EXTENDIBLE DIPPER
(H.E.D), Optional
The H.E.D as it is known extends the Backhoe Boom
by approximately 30% beyond the standard dipper
length and effectively increases dig depth by that
amount. Before attempting to use the H.E.D ensure
the Transport Locking pin position (1) is in the
unlocked position (2), Figure 125.
125
The H.E.D can be operated simultaneously with other
boom dipper and bucket movements to increase the
overall backhoe versatility, during most operations.
The working length of the dipper is variable between
the closed position and the maximum extension by
actuation of the floor mounted foot pedal control (1),
Figure 126.
NOTE: Continuous digging with the H.E.D extended
may cause structural damage to the boom assembly.
Retract the H.E.D whenever additional reach or
digging depth is not required.
126
NOTE: Pedal direction is as viewed from the operator
seat positioned facing to the rear of the machine:
Tilting the pedal forward (1) to the rear of the
machine, extends the dipper.
Tilting the pedal rearwards (2) to the front of the
machine retracts the dipper.
Intermediate dipper positions can be held by
releasing the pedal which will return to the spring
centred position.

SECTION 2 -- CONTROLS AND OPERATION
HAMMER ATTACHMENT
The machine may be fitted with an optional foot
operated hammer attachment.
IMPORTANT: Attachment of the hammer is the same
as for bucket attachment to the backhoe using the
existing hardware.
Refer to the hammer manufacturers installation and
operation handbook before proceeding and ensure
the hammer is securely fitted before operating.
The hammer is connected to the hydraulic circuit
using couplings (1) mounted on the backhoe boom
and operated by the foot switch (2) situated to the
right hand side of the backhoe control levers. This
switch when operated directs oil via a solenoid to the
hammer (3) for continuous operation. Release of the
switch stops the hammer working.
IMPORTANT: Before operating the hammer it is
essential to adjust the flow of oil to the hammer circuit
at the hammer flow control valve mounted on the
subframe at the rear of the machine. Precise flow
adjustment will require the use of a flow meter.
Contact your authorized dealer.
Approximate flow adjustment may be achieved by

SECTION 2 -- CONTROLS AND OPERATION
TRANSPORTING THE MACHINE,
Figure 130
When moving the unit from one site to another, or
when using the loader for any length of time, always
set the backhoe in the transport position as follows:
On sideshift machines position carriage to side of
backhoe frame. Refer to Page 2-80.
Fully retract the extendible dipper (1) (where
fitted) and install the transport pin (2), figure 125.
Fully raise and centre the boom.
130
Curl the bucket fully in.
Crowd the dipstick fully in.
On sideshift machines Activate the Backhoe
boom transport lock, refer to Figures 131 and 132.
Slew boom to cab and attach transport chain.
BACKHOE BOOM TRANSPORT LOCK,
Figures 131 and 132.
WARNING
To avoid injury never use the backhoe for ‘‘lifting’’ or
‘‘craning’’ with the backhoe locked in the transport
position.
To engage the boom/swing transport lock,
Figure 131, turn switch (1) ‘OFF’ (not illuminated)
which allows the backhoe lock plate to lower into the
latched position, an indicator light between the
backhoe lever’s indentifies the backhoe lock is in
operation.
131
Slew the boom into the transport position and use the
attaching chain to stabilizer leg or place pin (3) where
fitted into the boom plate:
Refer to Section 1, On Road requirements.
IMPORTANT: Fully raise the stabilizers before
attempting to drive off.
To release the backhoe locking plate turn the
transport lock switch ‘On’ and the latch will
disengage. The light on the switch will illuminate and
the indicator light between the backhoe control levers
will go out.
6.When driving the machine along the road local
regulations may require a marker board to be
fitted, attach the board to the lower end of the
bucket cylinder rod, refer to Section 1, On Road.
132
2--77
SECTION 2 -- CONTROLS AND OPERATION
BACKHOE OPERATION
STABILITY, Figure’s 133 & 134
Stability is the key to correct backhoe performance.
Before operating the backhoe, position the loader
bucket level on the ground and apply sufficient
downward pressure to transfer the weight from the
front wheels to the loader bucket.
IMPORTANT: The loader bucket must be flat on the
ground. Rolling the bucket forward so that the
cylinders are extended may cause bucket cylinder or
rod damage and will not necessarily improve stability.
Lower the stabilizers sufficiently to remove the weight
from the rear wheel.
IMPORTANT: THE REAR WHEELS SHOULD
REMAIN TOUCHING THE GROUND, Raising the
unit higher not only reduces stability and digging
depth, but will impair performance and impose
unnecessary stress in the unit.
To increase the lateral stability on the sideshift
backhoe the stabilizer pads may be reversed
(sideshift only). Ensure the stabilizer pads are
returned to their original positions before driving on
the road. Failure to carry out this operation will result
in the stabilizer pads protruding beyond the normal
width of the machine.
133
During normal digging, as the bucket penetrates the
ground and is filled, there is a tendency for the rear
of the unit to raise off the ground and move toward the
bucket. Properly set, the stabilizers anchor the unit
and prevent it from moving toward the bucket. The
ability of the stabilizers to hold depends on the
amount of weight acting on them.
NOTE: Where additional stability during operation of
the backhoe is required liquid ballast can be added to
the tires. Because special equipment is required to fill
the tires it is recommended that this be carried out by
your Dealer.
Stability is particularly important when operating the
backhoe at the extreme swing positions, Figure 134,
because of the tendency to lift one stabilizer and
transfer the total weight of the unit to the other
stabilizer.
WARNING
Do not overload the machine or exert forces that
the machine is not designed to handle. Ensure
when on a slope spoil is dumped up on the up side.
134
2--78
SECTION 2 -- CONTROLS AND OPERATION
Bucket Linkage Attachment, Figure 135
Two attaching pins and lynch pins secure the
backhoe bucket to the dipstick and bucket linkage.
Before commencing work examine the site to
establish the most suitable type of bucket and the
most appropriate bucket linkage position.
The bucket linkage positions (1), is suitable for the
majority of backhoe operations as it provides greatest
bucket power. Position (2) is best suited for straight
wall operations as it provides maximum bucket roll
out and curl. It also provides maximum clearance at
full height but slightly reduces bucket tear out power.
135
SIDE SHIFTING THE BACKHOE
(SIDESHIFT MODELS ONLY), Figure 136.
1. Lower the stabilizers to support the weight of the
unit.
2. Position the boom close to the backhoe frame and
set the backhoe bucket teeth into the ground.
3. Unclamp the backhoe swing frame (1) to the main
frame by depressing the switch (2) on the side
instrument panel.
136
4. Crowd the dipstick in or out to slide the swing
frame to the desired position. Maintain the swing
frame vertical in the slide channels by applying ‘lift’
or ‘lowering’ forces to the boom, Figure 137.
IMPORTANT: Once the boom is correctly positioned
swing the boom and dipper 90° to match the centre
line of the machine. This maneuver allows the
sideshift frame to settle in a true horizontal position.
5. Re--clamp the swing frame when the backhoe is
in the desired position by depressing the clamp
switch to the ‘Off’ position, Figure 136 and
pressurizing the hydraulic system by fully
operating one of the backhoe controls to achieve
maximum system pressure.
137
2--79
SECTION 2 -- CONTROLS AND OPERATION
OPERATING TECHNIQUES,
Figure’s 138 to 147.
WARNING
Never operate any of the backhoe control levers
with the transport boom lock engaged, refer to
Figure’s 131 and 132.
IMPORTANT: To achieve an optimum balance
between machine performance and optimum fuel
economy operate the machine at 1600--1700
rev/min.
Whenever possible operate two or more digging
elements during the bucket filling cycle for smooth
action and maximum performance. Control the
bucket angle during the digging cycle to keep the
bucket teeth at the best angle for maximum
penetration. This will minimize dragging and scraping
of the bucket through the soil.
138
Dump the bucket contents onto the spoil pile, rolling
out the bucket as the pile is approached. Avoid
constant jarring or hammering--type contact between
the spoil pile and bucket as this will cause wear to the
bucket pins and bushings.
To move the machine forward during backhoe
operation, Figure 139, raise the stabilizers and loader
bucket clear of the ground and curl the backhoe
bucket fully out. Position the dipstick vertically with
the bucket teeth in the ground or bottom of the trench
and slowly push the machine forward using the
dipstick crowd and boom lowering controls.
NOTE: When moving the machine forward using the
backhoe do not position the dipstick closer to the
machine than the vertical and ensure that the parking
brake is disengaged.
Lower the stabilizers and loader bucket before
resuming backhoe operations. The machine can be
moved sideways in a similar manner but the bucket
must be curled half--way in so that the weight of the
machine is applied to the bottom of the backhoe
bucket. Operate the swing control to move the
machine sideways to the desired position.
WARNING
When moving the machine with the backhoe avoid
swinging the backhoe to either side against the
stops. Doing so may damage the backhoe element.
To avoid the risk of damage and to extend the overall
life of machines installed with an extendible dipper the
following precautions must be observed.
2--80
139
SECTION 2 -- CONTROLS AND OPERATION
D When using the backhoe for a compacting
operation, the extendible dipper (if fitted) must be fully
retracted to position (1), Figure 140. The transport pin
and clip must then be installed to lock the sliding
components of the dipper together and protect the
cylinder from being damaged by shock loading. Prior
to resuming normal operation remove the transport
pin and re--install into the lower hole in the clevis on
the H.E.D (2).
D When using a toothed bucket to break hard
ground, avoid extending the dipper beyond 0.61m
(2 ft).
140
D When digging in wet soil or mud and the bucket
needs to be cleaned, do not knock the bucket against
the ground with the dipper extended.
141
D Avoid overloading the backhoe, Figure 142, by
using too large a bucket in heavy soil conditions. Like
any machine, if maximum capacity is maintained for
extended periods, the life expectancy will be reduced.
D Do not bottom--out the swing cylinder with the
dipper extended.
D Avoid swinging the boom to dump material on the
downhill side of the trench for your own safety, Figure
142.
WARNING
In the event of an overturn do not jump out of the
machine, stay in the cab.
D Do push material back into the trench using the
side of the bucket.
142
D When operating with the dipper fully extended,
ensure that the bucket does not receive a sharp
impact which will cause distortion of the cylinder rod.
2--81
SECTION 2 -- CONTROLS AND OPERATION
TRENCHING, Figure 143
1
Trenching is the most basic backhoe excavating
operation. Other digging operations are merely
variations of this basic function (i.e. filling the bucket,
dumping the bucket, and moving the unit forward).
While trenching, it is generally important to maintain
a level trench bottom. This is accomplished by setting
the bucket at the correct angle of approach. Pull on
the dipper lever to maintain the correct cutting angle
as the bucket is crowding in (1) applying light
pressure to the right. At the same time, pull on the lift
lever (2) to relieve down pressure and keep the
bucket in the same plane.
2
143
Continue the trench by moving forward. Moving too
far will require excessive down pressure for digging,
plus hand clean--up of the trench bottom. It is better
to move a lesser amount than to move too far.
When using the backhoe for digging on slopes
position the backhoe uphill wherever possible. If
however, this is not practicable use the loader or
backhoe to cut a level surface into the slope for the
uphill wheel and stabilizer, and deposit the spoil from
the slot onto the downhill side for the opposite wheel
and stabilizer. When digging always deposit the spoil
from the trench on the uphill side, Figure 144.
144
WARNING
When excavating across a slope it is not possible
to make use of the loader bucket for added stability.
Do not overload the bucket and avoid swinging a
loaded bucket to the downhill side of the slope.
To finish the far wall on a straight--walled excavation
crowd out the bucket while forcing the bucket down
the excavation from the boom. To finish the rear wall
crowd in the bucket, while lifting with the boom,
keeping the edges of the bucket horizontal.
2--82
145
SECTION 2 -- CONTROLS AND OPERATION
When finishing straight walls in sandy soil, position a
platform under the rear tires and stabilizers, Figure
146, to distribute the load over a larger area and
reduce the possibility of a cave--in. The platform will
also reduce the possibility of the machine creeping
rearwards if hard digging is encountered.
IMPORTANT: Do not backfill using the swing circuit
and dragging the bucket sideways. Doing so can
damage the dipstick, boom, swing cylinders or
mainframe.
To backfill a trench, Figure 147, lift the bucket over the
spoil pile and then crowd in the dipper (1) and lift the
boom (2). Pull both the crowd and boom levers
simultaneously for smooth even backfilling.
146
The backhoe can be used for lifting applications by
attaching a chain to the hook on the bucket link
(where fitted).

1
WARNING
Do not exceed the maximum safe working load of
the unit Figure 148. Ensure you comply with local
‘‘lifting’’ or ‘‘craning’’ regulations. If your machine
is to be used for craning a hose burst check valve
must be fitted in the hydraulic circuit, consult your
authorized Dealer.
When lifting with the backhoe, lift with the bucket
curled in and the dipper crowded in close to the boom.
147
WARNING
To avoid personal injury never use the backhoe for
‘‘lifting’’ or ‘‘craning’’ with the backhoe locked in the
transport position.
IMPORTANT: The Safe Working Load of the
backhoe is calculated using a standard bucket,
therefore, when using any other bucket or attachment
for ‘‘lifting’’ or ‘‘craning’’ the weight of the bucket or
attachment must be taken into account when
calculating the rated load of the backhoe.
Safe Working Load
The weights shown relate to the machine lifting a
weight through a radius of 3.4 meters from the
machine (Backhoe can be positioned anywhere
across the siedshift frame).
105 PS = 1000 kgs (2204 lbs)
+ kgs
Crowd the dipper out to lift the load up and out, then
swing slowly into position. For the final lift roll the
bucket out for accurate height adjustment of the load.
With the bucket rolled out slowly lower the load into
the desired position.

SECTION 2 -- CONTROLS AND OPERATION
BACKHOE QUICK RELEASE COUPLING
-- MECHANICAL, Figure 149.
A quick release mechanical Coupling (1), can be
fitted between the dipper and backhoe bucket by
means of the existing bucket retaining pins, as you
would for normal bucket attachment (2).
To connect the coupling to the bucket use retaining
pins in position (3) as you would for normal bucket
attachment. Roll back the coupling and position the
open jaw into the bucket top lift pin position (3). Roll
out the coupling and place the bucket sprung loaded
jaws into retaining pins as you would for normal
bucket attachment. If in any doubt consult the
manufacturers handbook, or your dealer.
WARNING
Ensure the safety pin is correctly fitted into the
coupler as explained in the manufacturers
instructions after each bucket change. If in any
doubt about fitting or adjustments, consult your
local authorized dealer.
Changeover of attachments is by release of the
sprung loaded jaw (with the safety pin removed)
using the handle (4) supplied to ease the spring
loaded jaw open.

SECTION 2 -- CONTROLS AND OPERATION
HAND HAMMER ATTACHMENT,
Figure 150.
WARNING
Before attempting to connect a hand hammer to the
machine ensure the console mounted switch (1)
which activates the hammer circuit is switched ‘Off’’
and the engine is turned ‘OFF’. This reduces all oil
pressure in the hammer circuit .

2
Refer to the hammer manufacturers installation and
operation handbook before proceeding with
installation and operation.
Hydraulic connection to the hammer is made by two
threaded couplings on the left hand side of the frame.
Coupling (3) provides flow from the hydraulics to the
hammer and Coupling (2) returns the oil to the
reservoir.
When attaching a hand hammer to the machine
ensure the couplings are free of dirt and
contaminates before coupling the hoses to the
machine.
150
Before operating the hammer it is essential to adjust
the flow of oil to the circuit at the hammer flow control
valve mounted beneath the machine on the sub
frame in front of the rear axle. Refer to the hammer
manufacturers instructions.
WARNING
Should it be necessary to adjust the flow control
valve to suite a different hammer, consult your
authorized dealer who has the the correct
equipment to check the flow required.
IMPORTANT: Ensure the machine parking brake is
applied and the transmission levers are in neutral
before operating the hammer.
151
The hammer can be operated while the backhoe is in
operation, however caution must be taken for the
personal safety of the operator that the hand hammer
does not enter the working area of the backhoe.

The tables on this page are for guidance only. For
exact information regarding inflation pressures and
loads for your particular tires, consult your authorized
Dealer.
Liquid Ballast
Filling the front and rear tires with liquid ballast is a
convenient method of adding weight. A solution of
calcium chloride and water is recommended. This
gives a low freezing point and provides a higher density than plain water.
when checking or adjusting air pressure if the tire is
liquid ballasted.
The table below shows the quantity of calcium chloride and water required for each tire size option and is
based on 0.6 kg of calcium chloride per Litre of water
to give a 75% fill of the tire. This calcium chloride/
water solution will give protection from freezing down
to an ambient temperature of --46°C (--51°F).
NOTE: Maximum allowable ballast to be added to
each rear tire should not exceed 1,050 pounds.
NOTE: When filling a tire with calcium chloride/water
solution the valve should be at the highest point on
the wheel. The valve should be at the lowest point
When mixing the ballast solution it is imperative
the calcium chloride flakes are added to the water
and the solution stirred until the calcium chloride is
dissolved. Never add water to calcium chloride. If
the flakes should contact the eyes, wash the eyes
immediately with clean, COLD water for at least 5
minutes. See a doctor as soon as possible.

DIESEL FUEL
moisture and sediment removal a drain plug should
be provided at the lowest point at the opposite end to
the outlet pipe. If there is no filter on the outlet pipe
then a funnel with a fine mesh screen should be used
when filling the machine fuel tank.
Before handling fuel, or filling tanks, observe the
following:
WARNING
Fuel purchases should be arranged so that summer
grade fuels are not held over and used in winter.
Under no circumstances should gasoline, alcohol
or dieselhol (a mixture of diesel fuel and alcohol) be
added to diesel fuel because of the increased fire
or explosion risks. In a closed container such as a
fuel tank they are more explosive than pure
gasoline. Do not use these blends. Additionally,
dieselhol is not approved due to possible
inadequate lubrication of the fuel injection system.
Refill the fuel tank mounted to the left of the cab.
PRE CLEANER, Figure 3.
Clean the filler cap area. Fill the tank at the end of
each day to reduce overnight condensation.
F
The Pre Cleaner mounted on top of the engine shroud
should be kept clean and free of all debris to allow free
air passage to the air cleaner.
Do not fill the tank to capacity. Allow room for expansion and wipe up spilt fuel immediately.
F
Two pre cleaners are available, a solid steel type for
normal construction site working or a deluxe glass
bowl type for use where larger airborne particles such
as grain may be present.
Never take the cap off or refuel with the engine
running or hot.
F
When filling the tank, keep control of the nozzle
and do not smoke.
F
As required remove the cleaner from the machine
and shake loose all residual debris. Wash in a non
sudsing detergent and ensure it is completely dry
before refitting to the machine
If the original fuel tank cap is lost, replace it with
an approved cap and tighten securely. A proprietary
cap may not be safe.
F
F
Keep equipment properly maintained.
Use fuels with a minimum cetane rating of 40 (diesel
fuel No. 2 at ambient temperatures above --7°C
(20°F) or No. 1 below this temperature). At very low
ambient temperatures and/or at high altitudes, a fuel
with a higher cetane rating is required. Diesel fuel with
a sulphur content above 1.3% is not recommended.
Precautions should be taken to ensure stored fuel is
kept free of dirt, water, etc. Fuel should be stored in
black iron tanks, not galvanized tanks, as the zinc
coating will react with the fuel and form compounds
that will contaminate the injection pump and injectors.
3
Bulk storage tanks should be installed away from
direct sunlight and angled slightly so sediment in the
tank will settle away from the outlet pipe. To facilitate

LOADER ARM SUPPORT, Figure 4.
The machines are equipped with a loader arm
support, which is stored on the left--hand loader arm
and retained in position by a pin and spring.
Remove the support from the lift arm and raise the
loader to full height position the support onto the
loader lift cylinder. Slowly lower the loader until the
support takes the weight of the loader and refit the
retaining strap (2). Do not apply down pressure on the
loader lift cylinders.
To remove the support remove the strap, raise the
loader to full height then lift and position the support
onto the loader arm. Retain the support to the loader
arm with the retaining pin then lower the loader to the
ground.

If necessary, remove the filler cap (1) right hand side
of engine and add oil through the filler tube. See
Specifications for the recommended oil grade.
RADIATOR COOLANT RECOVERY,
Figure 8
NOTE: Unless affected by leakage in the cooling
system topping up of the coolant is not necessary.
1
Your machine is equipped with a coolant recovery
system and as long as coolant is visible (1) between
the sight marks, topping up will not be required.
During operation of the machine the heating and
cooling process (expanding and contracting) of the
coolant is expelled or retrieved by the radiator from
the recovery tank.

WARNING
The cooling system is pressurized and care should
be taken when removing the expansion bottle cap
if the engine is hot. Coolant should be kept off the
skin. Adhere to the precautions outlined on the
antifreeze and inhibitor containers.
RADIATOR COOLANT
During manufacture, an antifreeze solution
containing a measure of chemical inhibitor is charged
into the cooling system of your machine to provide
protection from corrosion and freezing.
8
In the event of leakage, such as may occur with a
failed heater or radiator hose, the chemically charged
coolant will be lost. In this event, it is extremely
important that any lost coolant is replaced by the
correct coolant for your machine, refer to lubricants
and coolants at the back of the book or consult your
local authorized dealer.

OIL LEVEL, Figure 12.
The hydraulic system oil can be checked by
observing the sight glass (2) mounted below the step
on the hydraulic reservoir which is mounted to the
right of the cab.
NOTE: The hydraulic oil should be visible in the sight
glass when all cylinders in the loader and backhoe are
in the transport position.
Should the oil not be visible in the sight glass (2)
unscrew the oil reservoir filler (tamper proof) cap with
the wrench (1) provided and top up with the
recommended oil, see specifications.

SYSTEM FILTER BYPASS, Figure’s 13 & 14.
To ensure the hydraulic system components are not
starved of oil should the filter become blocked, a
by--pass valve diverts the oil directly to the filter outlet
port and may overheat the oil. Should this occur fit a
new oil filter as soon as possible.
13
Apply a thin film of clean oil to the filter sealing ring
and hand tighten the filter. Tighten the filter a further
3/ of a turn or as instructed on the new filter body.

SECTION 3 -- LUBRICATION AND MAINTENANCE
SERVICING THE ENGINE
CLEANER, Figure’s 15 to 17.
AIR
The function of the air cleaner is to remove impurities
from the air but at the same time allow sufficient
volume of air to enter the engine and ensure complete
combustion of the fuel. A poorly maintained air
cleaner will mean loss of power, excessive fuel
consumption and a reduction in engine life.
IMPORTANT: Clean the outer element ONLY when
the
restriction
indicator
light
illuminates.
Unnecessary and too frequent cleaning exposes the
element to handling damage which could allow dust
and dirt to by--pass the filter process and cause
engine wear.
If the air cleaner restriction warning light illuminates
while the engine is running, service the air cleaner as
soon as practical and certainly within one hour.
Extract the outer element (1) after removing the
retaining wing nut (2). If dust is present inside the
outer element, the element must be renewed. If
satisfactory, clean the element by tapping both ends
on the palm of the hand. Do not tap the element
against a hard surface as it will be damaged or
distorted.
15
16
Alternatively, compressed air, not exceeding 2 bar
(30 lbs in2) may be used. Insert the air line nozzle
inside the element and blow the dust from the inside
to the outside. Blow loose particles from the outside
of the element by holding the nozzle at least 150mm
(6in) from the element. Protect the eyes when
carrying out this operation.
NOTE: Do not remove or disturb the inner element
(3). If, after cleaning the outer element, it has a sooty
or oily appearance or if the air cleaner restriction
warning light does not extinguish or illuminates
shortly after servicing, then the outer element may
require washing in a non sudsing detergent or the
inner element needs replacing.
Clean the inside of the air cleaner casing using a
damp, lint--free cloth on a probe, taking care not to
damage the inner element. Re--install the outer
element ensuring that the rubber seal on the end is
not loose or damaged.

Always keep the battery terminals tight and free of
corrosion. If necessary, remove the battery and clean
the terminals and casing with a weak solution of
baking soda in water. Ensure the solution does not
get into the battery. Liberally coat both terminals with
petroleum jelly to prevent the formation of corrosive
deposits.

BATTERY ELECTROLYTE, Figure 19
WARNING
Low maintenance batteries do not require the same
service as conventional batteries. If your machine
is fitted with a low maintenance battery refer to the
manufacturer’s instructions regarding service or
consult your dealer.
Remove the vent plugs (1) and check the electrolyte
level which should be 6mm (0.25 in) above the
separator plates.
If necessary top up with distiled water and replace the
plugs. In cold climates this operation should be
carried out just before using the machine. The
charging action will mix the water with the electrolyte
and so prevent freezing of the battery.
WARNING
The battery contains a sulphuric acid electrolyte
which can cause severe burns and produce
explosive gases. Avoid contact with the skin, eyes
or clothing. Do not take internally. Treatment is as
follows:
Skin -- flush with cold water.
Eyes -- flush with cold water for 15 minutes and get
prompt medical attention.
Internal -- drink large quantities of water or milk followed by milk of magnesia, beaten eggs or vegetable
oil. Call a doctor immediately.
Do not use an open flame to check the electrolyte
level. Keep sparks, flames and cigarettes away. Do
not produce sparks with cable clamps when charging
the battery or starting the machine engine with a slave
battery.

CAB AIR FILTER, Figure 21
Before servicing the air filter situated under the drivers
seat, switch off the blower and close all windows and
one door. Forcibly close the other door. The resulting
back pressure will dislodge loose dirt from the
underside of the filters.
To remove the filter (1) release the retaining straps (2)
and remove the filter element. Ensure the element, and
sealing faces are not damaged on removal.
NOTE: In humid conditions, such as occur on most
early mornings, do not switch on the blower prior to
servicing the filters. Damp particles drawn into the
filter may solidify and prove difficult to remove without
washing.
The filter elements are made of specially treated
paper with a sealing strip bonded to the outer face.
Clean all of the elements by blowing with compressed
air from the clean side through to the dirty side. The
compressed air should not exceed 2 bar (30lb/in2) and
the air line nozzle should be at least 300 mm (12 in)
from the element.

BACKHOE LOADER STORAGE
The following precautions should be taken when
storing the machine for an extended period.
F
Thoroughly clean the machine and make good the
paintwork, where necessary, to prevent rust.
Check the machine for worn or damaged parts
and replace as necessary.
F
Lubricate the machine and drain the transmission,
hydraulic reservoir, rear axle and engine and refill with
the correct grades of oil.
F
Drain the fuel tank and pour two gallons (9 litres)
of special calibrating fuel into the tank.
F
Check the radiator coolant level. If the machine is
within 100 hours of the 1200 hour scheduled service
or within 2 months of the two year schedule service
perform the service as in maintenance.
F
Run the engine for 10 minutes to ensure complete
distribution of the special fuel through the injection
pump and fuel injectors. This will prevent gumming of
the injectors and pump during prolonged storage.
F
Operate the loader so all loader cylinders are in
the fully retracted position and all the bucket is resting
on a block or piece of wood.
F
F
Operate the backhoe until it is in the transport
position and attach the transport chain or engage the
transport lock.
Stop the engine and relieve all circuits of all hydraulic pressure.
F
Coat the exposed area of the backhoe and loader
hydraulic cylinder rods with a thin coating of light
grease.
F
3--42
SECTION 3 -- LUBRICATION AND MAINTENANCE
Remove and change the battery. Store in a dry
warm place and recharge periodically during storage.
F
Place blocks under the axles to remove the weight
from the tires.
F
F
Cover the exhaust pipe opening.
F
Lightly coat all exposed hydraulic piston rods with
a light grease, e.g. steering cylinder rams, spool
valves, etc.
TURBOCHARGER
Serious damage to the turbocharger bearing can result
from inadequate lubrication if the following
recommendations are not observed.
To prevent turbocharger bearing damage prior to the
first start after a turbocharger has been newly
installed or if for any reason, the oil supply to the
turbocharger has been disconnected, or in cases
where the engine is being started for the first time
after a period of 4 weeks or more without use, the
following procedure should be used:
1. Disconnect the inlet and outlet oil pipes from the
turbocharger and pour some clean engine oil into
the oil inlet port, taking care that no contaminates
enter the turbocharger.
2. Remove the air inlet tube from the turbocharger
and spin the compressor wheel by hand to pre-lubricate the bearings.
3. Re--connect the oil inlet and air inlet tubes but not
the oil outlet.
4. Disconnect the electrical wire to the fuel injection
pump fuel shut--off solenoid. Place a suitable receptacle below the oil outlet port and crank the
engine until oil flows from the outlet port.
PREPARING THE MACHINE FOR USE
AFTER STORAGE:
F
Inflate the tires to the correct pressure.
F
Refill the fuel tank.
F
Check the radiator coolant level.
F
Check all oil levels.
F
Install a fully charged battery.
F
Remove the exhaust pipe covering.
6. Check the engine oil level and add oil if necessary. Start the engine and check for oil and air
leaks.
7. Observe the oil pressure warning light. If the oil
pressure warning light is not extinguished in the
first few seconds of idling, stop the engine immediately and contact your dealer.
Remove any protective grease from affected
areas, e.g. steering cylinder rams, spool valves, etc.
F
5. Re--connect the oil outlet tube using a new gasket
and tighten the retaining bolts to the specified
torque, see Specifications Section 6. Re--connect the fuel injection pump fuel shut--off solenoid
wire.
On every start-up the engine should be allowed to idle
(1000 rev/min maximum) for 60 seconds before
operating on load, to ensure an adequate oil supply
to the turbocharger bearing. The engine should also
be allowed to idle without load for two minutes before
shut-down to enable the oil to dissipate the heat from
the turbocharger bearing.
3--43
SECTION 3 -- LUBRICATION AND MAINTENANCE
TIRES AND WHEELS
Do not inflate a tire unless the rim is mounted on
the machine or is secured so that it will not move if the
tire or rim should suddenly fail.
F
General Maintenance
Upon receiving your machine, check the air pressure
in the tires and re-check every 50 hours or weekly.
When fitting a new or repaired tire, use a clip-on
valve adaptor with a remote gauge that allows the
operator to stand clear of the tire while inflating it. Use
a safety cage, if available.
F
When checking tire pressures, inspect the tires for
damaged tread and side walls. Neglected damage
will lead to early tire failure.
Inflation pressure affects the amount of weight that a
tire may carry. Locate the tire size for your machine
in the Tire Pressure and Load tables in Section 6 of
this Manual. Do not exceed the load for the pressures
listed. Do not over or under inflate the tires.
WARNING
Inflating or servicing tires can be dangerous.
Whenever possible, trained personnel should be
called in to service or install tires. In any event, to
avoid the possibility of serious or fatal injury, follow
the safety precautions below:
Do not inflate a steering tire (front tire on a two
wheel drive machine) above the manufacturer’s
maximum pressure shown on the tire or beyond the
maximum shown in the Tire Pressure and Load
tables in Section 6, if the tire is not marked with the
maximum pressure.
F
machine wheels are very heavy. Handle with care
and ensure, when stored, that they cannot topple and
cause injury.
WARNING
F
Never inflate a traction tire (front tire on a four wheel
drive machine or any rear tire) over 35 lbs in 2 (2.4
bar). If the bead does not seat on the rim by the time
this pressure is reached, deflate the tire,
re-lubricate the bead with a soap/water solution
and re-inflate. Do not use oil or grease. INFLATION
BEYOND 35 lbs in 2 (2.4 bar) with unseated beads
may break the bead or rim with explosive force
sufficient to cause a serious injury.
F
Never attempt tire repairs on a public road or
highway.
F
Ensure the jack is placed on a firm, level surface.
Ensure the jack has adequate capacity to lift your
machine.
F
Use jack stands or other suitable blocking to
support the machine while repairing tires.
F
F
After seating the beads, adjust inflation pressure
to the recommended operating pressure.
WARNING
Do not re-inflate a tire that has been run flat or
seriously under-inflated until it has been inspected for
damage by a qualified person.
Do not use the stabilizers only as a means to lift the
machine, failure of a hose could have fatal results.
F
Do not put any part of your body under the
machine or start the engine while the machine is on
the jack.
F
F
Never hit a tire or rim with a hammer.
Ensure the rim is clean and free of rust or damage.
Do not weld, braze, otherwise repair or use a
damaged rim.
Torque wheel to axle nuts to specification after
re--installing the wheel. Check nut tightness daily until
torque stabilizes.

FOUR WHEEL DRIVE TIRE COMBINATIONS
The tires fitted to your machine with four wheel drive have been carefully selected to match the gearing of the
transmission and axles. When renewing worn or damaged tires, always install tires of the same make, model
and size as those removed. The installation of other tire combinations may result in excessive tire wear, loss
of usable power or severe damage to drive line components. If in doubt, consult your Dealer.
WHEEL PRESSURES AND PERMISSIBLE LOADS
The following charts give the carry capacity of the axle at the tire pressures indicated.
These charts are for guidance only. For exact information regarding inflation pressures and loads for your
particular tires, consult your Dealer.

ROAD SPEEDS
The following table shows the approximate ground speeds in km/h and miles/h at rated engine speed (2070
rev/min). The ground speed at any other engine speed may be derived from the tables by using a simple
calculation.
Example:
Ground speed required at 1500 rev/min. in 3rd gear ratio, forward travel, on a machine equipped with 16.9 -- 24
Industrial Sure Grip tires.
From the appropriate table the ground speed at 2200 rev/min. is found to be 35.2 km/h (22 miles/h).
