Aerial Lifts
Pre-Operation Inspection
– Be sure that the manuals are legible and in
the storage container located on the
– Be sure that all decals are legible and in
– Check the hydraulic power unit oil level
– Platform and Ground Control Panel must
be tested prior to use to determine that

Aerial Lifts
Work Place Inspection
– Do a visual inspection of the work area
prior to beginning work
• Hazardous locations
– Drop-offs or holes
– Bumps, floor obstruction or debris
– Inadequate surface support to withstand all load
forces imposed by the machine
• Clearance
• Overhead obstructions
– High voltage conductors
• The presence of unauthorized personnel
• Other possible unsafe conditions
Aerial Lifts
Set up for TZ-50
– Operation from Ground
• Position the machine below the desired work area
• Turn the key switch to ground control position
• Pull out the red Emergency Stop buttons at the ground to
the on position
– Auto Level
• Push & hold the yellow function enable button
• Push and hold the auto level button
• The outriggers will lower & adjust to level the machine &
raise the wheels off the ground
• Level the machine using only the outriggers
• Use the bubble level located below the ground controls to
make sure the machine is level.

to determine the direction of machine travel.
• Before raising the platform, lower the outriggers and
adjust to level machine and raise the wheels off the
Aerial Lifts
Set up for AWP-24, AWP-30S, & UL-31/37:
– Remove the four (4) outriggers from their storage
sockets and slide into base sockets until lock pins
snap into outrigger holes.
– Check the interlock display lights at the ground
controls (AWP -24 and AWP-30S only):
• Confirm that the corresponding light is on
• If the interlock display light is flashing, continue adjusting
the outrigger until the light is on
– While watching the base bubble level, continue to
adjust each leveling jacks until base is level (bubble
in the center circle)
– Repeat procedure for each of the remaining

is occupied.
Aerial Lifts
Safe Work Practices Cont.
– Employees shall always stand firmly on the
floor of the basket.
• Do not stand, sit or climb on edge of the basket
or guard rails.
• Do not use planks, ladders, or other devices for
a work position.

Aerial Lifts
Two Major Safety Hazards:
– Electrocution Hazards - Caused by
operating close to power lines.
It is easy to accidentally contact energized
power lines.
This machine is not electrically insulated and
will not provide protection from contact with
electrical current.
If lift comes in contact with energized lines,
personnel on the ground or in the platform
must not touch or operate the machine until
energized power lines are shut off.
Do not operate the machine during lighting or
