Lippert Components Hydraulic Slideout And Hydraulic Landing Gear (hlg) System - Manual (Page 6)

SYSTEM MAINTENANCE
The Lippert Hydraulic Slideout and HLG System has been static tested to over
6,000 continuous cycles with out any noticeable wear to rotating or sliding parts.
It is recommended that when operating in harsh environments (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.
ELECTRICAL SYSTEM MAINTENANCE
For optimum performance, the 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 electric actuator motor for corrosion, and loose or
damaged terminals. Check motor leads under the trailer chassis. Since these
connections are subject to damage from road debris, be sure they are in good
condition.
Note: The Lippert Hydraulic Slideout and HLG System is designed to operate
as a negative ground system. A negative ground system utilizes the chassis
frame as a ground and an independent ground wire back to battery is necessary
(see page 19 for wiring diagram). It is important that the electrical components
have good wire to chassis contact. Over 90% of unit electrical problems are due
to bad ground connections.
MECHANICAL SYSTEM MAINTENANCE
Although the system is designed to be almost maintenance free, actuate the
slideouts and jacks once or twice a month to keep the seals and internal moving
parts lubricated.
Check for any visible signs of external damage or “leakage” before and after
movement of the unit.
When the room is out, visually inspect the Inner and Outer Assemblies of the
slideout. Refer to Fig. 1 for location of inner assemblies. Also inspect around
the shoe of the leveling jacks for signs of leakage. 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 to the drive shaft and roller areas of the slideout only but remove
any excess oil so dirt and debris do not build-up. DO NOT USE GREASE.
NOTE: For long-term storage: It is recommend that the room be closed
(retracted).
