Maintenance

1.
Each month, check that the fluid level is within 1/4" of the fill spout lip while jacks and slide-outs are
fully retracted.
NOTE: Always fill the reservoir with the jacks and slide-outs in the fully retracted position. Filling reservoir
when jacks and slide-outs are extended will cause reservoir to overflow into its compartment when
jacks and slide-outs are retracted.
2.
Inspect and clean all power unit electrical connections prior to the first use of the unit of the season
and prior to storing the unit. If corrosion is evident, clean all corrosion with a wire brush and apply
dielectric grease to the connections.
3.
Remove dirt and road debris from jacks as needed.
4.
If jacks are down for extended periods, it is recommended to spray exposed leveling jack rods with a
silicone lubricant every three months for protection. If the unit is located in a salty air environment, it is
recommended to spray the rods every 4 to 6 weeks.
Fluid Recommendation
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. For a
list of approved fluid specifications, see TI-188.
