System and Safety Information
Failure to act in accordance with the following may result in death or serious injury.
The use of the Ground Control® 2.0 to support the unit for any reason other than that which it is intended is prohibited by Lippert’s limited warranty. The Lippert Ground Control® 2.0 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. Lippert Components Inc. recommends that a trained professional be employed to change the tire on the unit. Any attempts to change tires or perform other service while unit is supported by the Ground Control® 2.0 could result in death, serious injury or damage to the 5th Wheel.
NOTES: A. B.
C. D. E.
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 unit 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.
Prior to Operation
The leveling system shall only be operated under the following conditions:
1. The unit is parked on a reasonably level surface.
2. Be sure all persons, pets and property are clear of the coach while Lippert Ground Control® 2.0 is in
operation.
3. Make sure battery(ies) are fully charged and load test at 12+V DC.
4. Drop inner leg of both landing gear jacks to within 4-5 inches of the ground.

Basic Jack Operation
1. Front Landing gear jacks. 2. Rear leveling jacks. Landing Gear jacks can be operated any time the system is “ON” but NOT in the “AUTO MODE.” By pushing the “FRONT” button, both front or landing gear jacks can be extended. By pushing either the “LEFT” or “RIGHT” button, the individual front jacks can be extended. If the touch panel is put in the “RETRACT” mode, indicated by the orange illuminated LED next to the “RETRACT” button, the front jacks can be retracted together by pushing the “FRONT” button or individually by pressing either the “LEFT” or “RIGHT” button. The rear jacks can only be operated when the touch panel is in the “MANUAL MODE.” Once system is in “MANUAL MODE,” pressing the “REAR” button will extend both rear jacks at the same time. To operate individual rear jacks, press the “LEFT” or “RIGHT” button first, depending on what is needed at the time, then press the “REAR” button and hold both at the same time.
Dropping Off Unit
1. Park coach on level ground. 2. Chock all tires. 3. Make sure battery power is on. 4. Release front jack legs to within 4-5 inches from the ground by pulling out the quick release pin (Fig. 1A). 5. Release inner legs on rear leveling jacks — 2 (4-point) or 4 (6-point) — by pulling the quick release pins. 6. At this point, you may use automatic controls on your LincTM remote if supplied. If no Linc remote is supplied,
continue to step 7. IMPORTANT: For LincTM automatic leveling and retraction instructions, refer to your owner’s packet. 7. Press “ON/OFF” button to turn panel on (Fig. 2E). 8. Push “UP ARROW” button (Fig. 2A) and scroll to “DROP FRONT JACKS” option on LCD screen. 9. Push “ENTER” button (Fig. 2B). Front legs will lower to ground and stop. 10. Disconnect 5th wheel latch. 11. Push “FRONT” button (Fig. 2D) to extend front landing gear jacks manually and lift front of vehicle to clear 5th wheel plate. 12. Pull tow vehicle away and park at a safe distance. 13. Push “AUTO LEVEL” button (Fig. 2C). The unit will commence auto-level feature by setting front landing gear jacks to level, then dropping rear jacks followed by a leveling sequence check. On the 6 point system, the middle jacks will now lower to the ground to stabilize the unit. When auto-level sequence is complete, LCD screen will indicate, “AUTO LEVEL SUCCESS.” “Level Jacks: Down” will then appear, along with a green light in the middle of the jack buttons. 14. Press the “ON/OFF” button (Fig. 2E) to turn system off.

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).
2. Once the unit is level, turn off the touch pad. 3. With the touch pad off, press and release the “FRONT” button 10 times and then press and release the
“REAR” button 10 times. 4. The touch pad will flash and beep and the display will read “ZERO POINT CALIBRATION ENTER to set,
Power to Exit” (Fig. 5). 5. To set the current position as the zero point, press the “ENTER” button. 6. LCD display will read “Zero Point stability check” (Fig. 6). 7. LCD display will read “Zero point set successfully” once process is complete (Fig. 7). 8. The system will set this point as its level state and the touch pad will turn off.

Troubleshooting
Special Jack Error Codes
To clear one of these errors: 1. Correct or otherwise repair the issue (see the table below). 2. Extend all of the jacks at least 6 inches, then press and hold the “RETRACT” button on the touch pad
until the jacks begin retracting. 3. All of the jacks will retract fully to clear the error.
NOTE: Landing gear will also retract at this time. Ensure the 5th wheel hitch pin is supported by either the tow vehicle or a tripod stand.

Preventative Maintenance Procedures
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 your coach is located in a salty environment, it is recommended to spray the rods every month.
Ensure the unit 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.
