Page 3: Introduction
Introduction The Lippert Electronic Leveling System is an electric/hydraulic system. A 12V DC electric motor drives a hydraulic pump that moves fluid through a system of hoses, fittings and jacks to level and stabilize the coach. The use of the Lippert Electronic Leveling System to support the coach for any reason other than which it is intended is prohibited by Lippert’s limited warranty. -

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. -
