OPERATION AND SERVICE MANUAL
SYSTEM
FAILURE TO ACT IN ACCORDANCE WITH THE FOLLOWING MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
THE USE OF THE LIPPERT ELECTRONIC LEVELING SYSTEM TO SUPPORT THE COACH 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.
LIPPERT COMPONENTS, INC. RECOMMENDS THAT A TRAINED PROFESSIONAL BE EMPLOYED TO CHANGE THE TIRE ON THE
COACH. ANY ATTEMPTS TO CHANGE TIRES OR PERFORM OTHER SERVICE WHILE COACH IS SUPPORTED BY THE LIPPERT
LEVELING SYSTEM COULD RESULT IN DAMAGE T O THE MOTOR HOME AND/OR CAUSE SERIOUS INJURY OR DEATH.
BE SURE TO PARK THE COACH ON SOLID, LEVEL GROUND.
CLEAR ALL JACK LANDING LOCATIONS OF DEBRIS AND OBSTRUCTIONS.
LOCATIONS SHOULD ALSO BE FREE OF DEPRESSIONS.
WHEN PARKING THE COACH ON EXTREMELY SOFT SURFACES, UTILIZE LOAD DISTRIBUTION PADS
UNDER EACH JACK.
PEOPLE AND PETS SHOULD BE CLEAR OF COACH WHILE OPERATING LEVELING SYSTEM.
BE SURE TO KEEP HANDS AND OTHER BODY PARTS CLEAR OF FLUID LEAKS. OIL LEAKS IN THE LIPPERT LEVELING
SYSTEM MAY BE UNDER HIGH PRESSURE AND CAN CAUSE SERIOUS SKIN PENETRATING INJURIES.
NEVER LIFT THE COACH COMPLETELY OFF THE GROUND. LIFTING THE COACH SO THE WHEELS ARE
NOT TOUCHING GROUND WILL CREATE AN UNSTABLE AND UNSAFE CONDITION.
The leveling system shall only be operated under the following conditions:
1. The coach is parked on a reasonably level surface.
2. The coach “PARKING BRAKE” is engaged.
3. The coach transmission should be in the neutral or park position
4. THE ENGINE MUST BE RUNNING!
5. Be sure all person, pets and property are clear of the coach while Lippert Leveling System is in operation.
Please read and study the operating manual before you operate the leveling system.
The Lippert Electronic Leveling System is an electric/hydraulic system. A 12V DC electric motor drives a hydraulic pump that
moves fluid through a system of hoses, fittings and jacks to level and stabilize the coach.
The Lippert Electronic Leveling System is totally integrated into the chassis of the coach at the manufacturer.
There are no serviceable parts within the electric motor. If the motor fails, Pump Unit must be replaced.
Disassembly of the Pump Assembly voids the warranty.
Mechanical portions of the Lippert Electronic Leveling System are replaceable. Contact Lippert Components, Inc. to obtain
replacement parts.
The Lippert Electronic Leveling System consists of the following major components:
Lippert jacks are rated at a lifting capacity appropriate for your coach. Each jack has a 9" diameter (63.5 square inch) shoe on a ball
swivel for maximum surface contact on all surfaces. (12” dia. - 113 sq. in. shoe also available).
Each jack is powered from a central 12VDC motor/pump assembly, which also includes the hydraulic oil reservoir tank, control valve
manifold, and solenoid valves.
The Lippert Electronic Leveling System is controlled electronically from the driver ’s seat of the coach. The control panel is
mounted in the dash. The system can be operated in a manual mode or a fully automatic mode.
The Lippert Electronic Leveling System is pre-filled, primed and ready to operate direct from the manufacturer. Type “A” Automatic
Transmission Fluid (ATF) is utilized and will work. ATF with Dexron III or Mercon 5 or a blend of both is recommended by Lippert
Components, Inc. In colder temperatures (less than 10° F) the jacks may extend and retract slowly due to the fluid’s molecular
nature. For cold weather operation, fluid specially formulated for low temperatures may be desirable. Please consult factory before
using any other fluids.
COMPONENT DESCRIPTION
WARNING!
PRIOR TO OPERATION
SYSTEM DESCRIPTION
FLUID RECOMMENDATION
1. Change fluid in RESERVOIR ONLY every 36 months.
a) Check fluid only when jacks are fully retracted.
b) Always fill the reservoir with the jacks in the fully retracted position. Filling reservoir when jacks are extended will cause
reservoir to overflow into its compartment when jacks are retracted.
c) When checking fluid level, fluid should be within ¼” of fill spout lip.
2. Check the fluid level every month.
3. Inspect and clean all Pump Unit electrical connections every 12 months. If corrosion is evident, spray unit with WD-40 or equivalent
4. Remove dirt and road debris from jacks as needed.
PREVENTATIVE MAINTENANCE PROCEDURES
Your coach should be supported at both front and rear axles with jack stands before working underneath.
5. If jacks are down for extended periods, it is recommended to spray
exposed leveling jack rods with a silicone lubricant every seven days for
protection. If your coach is located in a salty environment, it is
recommended to spray the rods every 2 to 3 days.
Failure to do so may result in personal injury or death.

System has the option to control external Air and Auxiliary features.
When enabled, the feature works according to the following logic:
· Air bag pressure automatically lowered when starting the auto or manual sequence to maximize lift of jacks.
· An Auxiliary mode activated when starting an auto retract sequence to fill air bags.
· Auxiliary is active when jacks are all retracted and park brake is disengaged to fill airbags.
SYSTEM WIRING REQUIREMENTS
AIR AND AUXILIARY FEATURES
FEATURES
LEVEL ZERO POINT CALIBRATION
Before auto-leveling features are available, the Level Zero point must be set. This is the point to which the system will return
when an auto leveling cycle is initiated.
To set the zero point (controller module must be fully secured in production intent location), first run a manual leveling sequence
to get the vehicle to the desired level point. Then activate the Level Zero point configuration mode.
This mode is enabled by performing the following sequence:
For DIESEL UNITS with Airbag Suspensions ONLY:
NOTE - You may also enter zero mode per above at anytime the system is in IDLE mode. The user then has control to extend
any pair of jacks while in zero mode in order to position the vehicle properly prior to programming.
AIR AND AUXILIARY FEATURE CONFIGURATION
For DIESEL UNITS with Airbag Suspensions ONLY:
To enable Air Auxiliary features, perform the following:
To disable Air features, perform the following:
1. Turn panel off. Then turn panel on.
2. Perform the following:
3. At this point all LED outputs will blink, and the buzzer will be off.
4. You are now in IDLE mode ready to set Zero Point.
5. With a carpenter’s level, manually level the coach. This will give the leveling controls the reference point for the
Zero Point Configuration.
6. When coach is completely leveled manually press the RETRACT ALL switch 3 times to set the zero point.
· Feature is entered ONLY after zero mode programming.
· At this point the WAIT LED will blink for 20 seconds. You are now in Air/Auxiliary Feature Configuration mode.
· Press the RETRACT ALL switch 3 times
· User must do this within 20 seconds of entering this mode.
· Do nothing
· After 20 seconds, module will exit mode with features disabled.
-Press the FRONT switch 5 times.
-Press the REAR switch 5 times.
