Fluid Recommendation
Automatic transmission fluid (ATF) with Dexron®III or Mercon®V or a blend of both is recommended by
Lippert Components, Inc. For a list of approved fluid specifications, see TI-188. To obtain this Technical
Information sheet on-line, go to http://www.lci1.com/support-lci4a3lcd. Then click on the Technical
Information Sheets tab. Look for TI-188: Hydraulic Operation Fluid Recommendation within the listing.
NOTE: 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.
Preventive Maintenance
1. Check hydraulic fluid in reservoir every 12 months. If fluid is a clear, red color do not change. If fluid is
milky, pink and murky and not clear red in color, drain reservoir and add new fluid. Hydraulic fluid in
reservoir should be changed a minimum of every five years.
NOTE: Check the fluid only when all the jacks are fully retracted.
NOTE: When checking the hydraulic fluid level, fill to within ¼" to ½" of fill spout.
2. Inspect and clean all power unit electrical connections every 12 months. If corrosion is evident, use a
small amount of lubricant to remove corrosion. Contacts must be cleaned with a non-residue cleaner
prior to use. LCI recommends the use of an electrical contact cleaner spray.
3. Remove dirt and road debris from jacks as needed.
4. If jacks are down for extended periods of time, it is recommended to spray exposed jack rods with a dry
silicone lubricant every three months for protection. If the coach is located in a salty environment, it is
recommended to spray the rods every 4 - 6 weeks.
The coach should be supported at both front and rear axles with jack stands before working
underneath. Failure to do so may result in death, serious personal injury, severe product or
property damage.
