System and Safety Information Prior to Operation
The leveling system should only be operated under the
following conditions:
1. The unit is parked on a reasonably level surface.
Failure to act in accordance with the following
may result in death or serious personal injury. The
use of the Ground Control 3.0 leveling system to
support the unit for any reason other than which it
is intended is prohibited by Lippert’s limited warranty. The Lippert leveling system is designed as
a “leveling” system only and should not be used
to provide service for any reason under the coach
such as changing tires or servicing the leveling
system. Any attempts to change tires or perform other service while unit is supported by the
Ground Control 3.0 leveling system could result
in damage to the 5th wheel and/or cause death or
serious injury.
2. Be sure all persons, pets, and property are clear of the
coach while the leveling system is in operation.
3. Make sure battery(ies) are fully charged and test at
12+VDC under load.

Be sure to park the unit on solid, level ground.
Clear all jack landing locations of debris and
obstructions. Locations should also be free of
depressions. When parking the unit on extremely
soft surfaces, utilize load distribution pads under each jack. People and pets should be clear of
coach while operating leveling system. Never lift
the unit completely off the ground. Lifting the unit
so the wheels are not touching the ground will
create an unstable and unsafe condition.

Basic Jack Operation
NOTE: If the jacks do not retract, an error should display on
the touch pad screen. This is typically caused by wiring
interruption.
Landing gear jacks can be operated any time the system is “ON”.
By pushing the “FRONT” button (Fig. 16G), both front or landing
gear jacks can be extended. By pushing either the “LEFT” (Fig.
16H) or “RIGHT” (Fig. 16I) buttons, the individual front jacks can
be extended. If the touch pad is put in the retract mode, indicated
by the orange illuminated LED next to the “RETRACT” button
(Fig. 16D), the front jacks can be retracted together by pushing
the “FRONT” button (Fig. 16G) or individually by pressing “LEFT”
(Fig. 16H) or “RIGHT” (Fig. 16I) buttons, while simultaneously
pressing the “FRONT” button (Fig. 16G).
Zero Point Calibration
The “Zero Point” is the programmed point that the unit will return
to each time the Auto Level feature is used. The “Zero Point”
must be programmed prior to using the Auto Level feature to
ensure the proper operation of the system.
NOTE: Prior to starting this procedure, double check all
connections on the controller, jacks, and touch pad.
1. Manually run the jacks to level the unit. This is best achieved by
placing a level in the center of the unit and leveling it both front
to back and then side to side. (See “Basic Jack Operation” for
instructions on how to manually operate the system).
The rear jacks can only be extended when the touch pad is in
the manual mode. Once system is in manual mode, pressing
the “REAR” button (Fig. 16J) will extend both rear jacks at the
same time. To extend individual rear jacks, press the “LEFT”
(Fig. 16H) or “RIGHT” (Fig. 16I) buttons while simultaneously
pressing the “REAR” button (Fig. 16J) depending on which jack
needs to be operated. If the touch pad is put in the retract mode,
indicated by the orange illuminated LED next to the “RETRACT”
button (Fig. 16D), the rear jacks can be retracted together by
pushing the “REAR” button (Fig. 16J) or individually by pressing
either the “LEFT” (Fig. 16H) or “RIGHT” (Fig. 16I) buttons, while
simultaneously pressing the “REAR” button (Fig. 16J).
2. Once the unit is level, turn off the touch pad.
3. With the touch pad off, press and release the “FRONT” button
(Fig. 17A) five (5) times and then press and release the
“REAR” button (Fig. 17B) five (5) times.
4. The touch pad will flash and beep and the display will read
“ZERO POINT CALIBRATION ENTER to set, Power to Exit”
(Fig. 17C).
5. To set the current position as the zero point, press the
“ENTER” button (Fig. 17D).
NOTE: If the rear jacks will not operate individually using the method
described above, but they operate properly when Auto Level is
performed, the Twist Prevention Protection system has locked out
the operation to prevent damage to the frame of the unit.
Homing Jacks
1. Introduce an error - disconnect one of the hall effect sensor
wires at the controller.

Preventive Maintenance
1. Remove dirt and road debris from jacks and stabilizer
struts (if equipped) as needed.
2. If jacks are down for extended periods, it is
recommended to spray exposed leveling jack tubes
with a spray lubricant every 3 months for protection.
If the coach is located in a salty environment, it is
recommended to spray the rods every month.
Ensure the coach is supported at both the front
and rear with jack stands before performing any
troubleshooting or service to the unit. Failure to
do so may result in death or personal injury.
