Lippert Components Hydraulic Landing Gear - 14k Aluminum - Manual (Page 2)

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.
AUXILIARY OPERATION
The LIPPERT HYDRAULIC LANDING GEAR can be run with power devices like electric drills or cordless screwdrivers. In the event of
electrical or system failure, this manual method of extending and retracting the jacks can be used. A standard handheld cordless or power
drill is all that is required. See the instructions below:
3. Remove protective label. (See Fig 1).
4. Using a standard hex bit, insert into auxiliary drive device,
i.e. cordless drill or power drill
5. Insert hex bit into coupler found under protective label, Fig. 2.
6. Run drill forward or clockwise to extend jacks and in reverse or
counterclockwise to retract jacks.
WARNING!
DO NOT WORK ON YOUR SLIDEOUT SYSTEM UNLESS THE BATTERY IS DISCONNECTED.
FAILURE TO ACT IN ACCORDANCE WITH THE FOLLOWING MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
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 and 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 Fig. 3, 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.

1. Locate the blocking valve on the top cap of either of the
landing gear jacks.
2. Using a 5/32” Allen wrench, manual open the valve by turn
the manual override set screw in the end of the valve clockwise.
7. be sure to turn manual override set screw back to the
counterclockwise position after extnding or retracting
landing gear.
