Preventative Maintenance Procedures

The Lippert Hydraulic Landing Gear has been designed to require very little maintenance. To ensure the long life of
your slide-out system, read and follow these few simple procedures.
1.
Check the fluid level every month.
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 1/4" of fill spout lip.
2.
Inspect and clean all Pump Unit electrical connections every 12 months.
3. Remove dirt and road debris from Landing Gear as needed.
The coach should be supported at both front and rear axles with jack stands before working underneath.
The Lippert Hydraulic Landing Gear has been static tested to over 6,000 continuous cycles without any noticeable
wear to rotating or sliding parts. It is recommended that when operating in harsh environments and conditions
(road salt, ice build-up, etc.) the moving parts be kept clean. They can be washed with mild soap and water. No
grease or lubrication is necessary and in some situations may be detrimental to the environment and long-term
dependability of the system.

Mechanical Components

Although the system is designed to be almost maintenance-free, actuate the landing gear once or twice a week to
keep the seals and internal moving parts lubricated.
Check for any visible signs of "leaking" before and after movement of the system and the coach.
When the landing gear is down, visually inspect the inner and outer assemblies. Refer to components list for
location of inner assemblies. Check for excess build-up of dirt or other foreign material; remove any debris that
may be present.
If the system squeaks or makes any noises it is permissible to apply a coat of lightweight oil or silicone lubricant
spray to the hydraulic rod but remove any excess oil so dirt and debris do not build-up. DO NOT use grease.

Electrical Components

For optimum performance, the landing gear system requires full battery current and voltage. The battery must be
maintained at full capacity. Other than good battery maintenance, check the terminals and other connections at
the battery, the control switch and the pump motor for corrosion and loose or damaged terminals. Check motor
leads under the coach chassis. Since these connections may be subject to damage from road debris, be sure they
are in good condition.
NOTE: The Lippert Hydraulic Landing Gear is designed to operate as a negative ground system. A negative
ground system utilizes the chassis frame as the ground source. An independent ground wire back
to the battery is not needed. It is important the electrical components have good wire to chassis
contact. Over 90% of unit electrical problems can be attributed to bad ground connections.
NOTE: For long-term storage: It is recommended that the room be closed (retracted) and if your unit is
equipped with the IRC room control, it is recommended all of the control knobs be kept in the
closed position.

Failure to do so may result in death or serious injury.
