6) that moves fluid through a system of hoses, fittings and jacks to level and stabilize the coach. Mechanical portions of the hydraulic leveling system are replaceable. Contact Lippert to obtain replacement parts. The hydraulic leveling system is primed and tested at the factory. However, the system is shipped dry to avoid hazardous material restrictions.
Lippert limited warranty. The "WARNING" symbol above is a sign that a procedure has a safety risk involved and may cause death or serious personal injury if not performed safely and within the parameters set forth in this manual.
Preparation Make sure to park the coach on solid and level ground. Clear all jack landing locations of debris and obstructions. Keep hands and other body parts clear of fluid leaks. Hydraulic system leaks in the hydraulic leveling system may be under high pressure and can cause serious skin-penetrating injuries. Never lift the coach completely off the ground.
Installation Prior to Installation Refer to the Hydraulic Plumbing Diagram (Fig. 51) for the following steps: Identify where the extend (Fig. 3A) and retract ports (Fig. 3B) are on the jack. Verify that the ports are clear of any residual machining metal debris. Label each jack Left Front (LF), Right Front (RF), Right Rear (RR) or Left Rear (LR).
Hydraulic Power Unit Installation NOTE: The location where the hydraulic power unit will be installed should be as near center on the coach as possible. Install the hydraulic power unit in accordance with RVIA Gas Codes, since the hydraulic power unit connections are not spark proof. Identify the hydraulic power unit mounting location.
NOTE: Hose loops should be secured in the horizontal position to prevent trapped air pockets. NOTE: Before operating the Lippert hydraulic leveling system, make sure the system has been properly purged of air that was introduced into the hydraulic lines during the installation.
Prepping the Front Jack Bracket Installation Starting with the passenger side, remove the black molded plastic step well cover (Fig. 9D) in the cab of the coach. Remove the top trim piece (Fig. 9C) located on the top of the step well area (Fig. 9A). There are two caps (Fig.
Front Jack Bracket Installation Mounting hole edges on the backside of the jack (Fig. 13E) may be sharp and should be handled with care. Serious personal injury may occur if not using safety equipment such as gloves when handling the jacks. NOTE: A recommended minimum ground clearance between the bottom of the jack footpad and the ground, is 7-9"...
Page 11
Position the jack assembly (Fig. 15A) onto the frame rail (Fig. 15B). Clamp or have another person hold the jack in place, making sure the bolting surface of the mounting brackets line up with the holes drilled in the frame. From the step well side, insert four 7/16"- 14 x 1 1/4"...
Rear Jack Bracket and Jack Installation Turn the rear jack so that the built-in bracket for the bolts (Fig. 17A) are facing the rear of the coach. At the bottom of each inside face of the jack (Fig. 17B), remove the retract and extend port plugs and attach two JIC 90 degree elbow retract fittings (Fig.
LED Touch Panel / Controller Installation Images used in this document are for reference only when assembling, installing and/or operating this product. Actual appearance of provided and/or purchased parts and assemblies may differ. The front panel orientation of the touch panel / controller must be either in an X axis (roadside/curbside) orientation or Y axis (front/rear) orientation (Fig.
Battery ground cable (RVIA standard) connecting the 12V DC battery, to the ground post on the hydraulic power unit motor. NOTE: Lippert recommends connecting the ground cable directly to the battery, rather than a chassis ground point. Leveling jack status input - pressure switch.
The coach transmission should be in the park position. Be sure to keep hands and other body parts clear of fluid leaks. Oil leaks in the Lippert Leveling System may be under high pressure and can cause serious skin penetrating injuries.

Figure 25 is assigned to “Manual Mode” button from menu screen (Fig. 24B). Each button, ex. Extend Front (Fig. 25A) is a button that operates both front jacks. Each button is a pair of jacks and only extends the jacks. Figure 26 is the screen displayed during the leveling process.

During the, "Retract Jacks" (Fig. 23C), or in "Manual Mode", (Fig. 24B), Figure 28, "Jacks Are Retracting" screen is displayed. Figure 29, "Parking Brake Error", will appear when no parking brake signal is received and there is no pressure switch signal indicating jacks are still retracted. The screen is prompted before auto level and manual mode functions.
Page 18
10. Figure 31, "Retract Error" screen will appear if with ignition on and touchpad on or in “sleep” mode (display off, power to control still on). If the control receives signal from the pressure switch (meaning the internal pressure of the hydraulic system has dropped below 2,150 psi, connection lost from pressure switch to control), the control enters retract all mode.
Level Zero Point Calibration After the system is installed and power is supplied, the Zero Point needs to be calibrated on the LED touchpad controller, prior to operating the jacks. Zero Point is the programmed point that the coach will return to each time the Auto Level feature is used.
Page 20
Follow the directions on the next screen (Fig. 35) to calibrate the LED touchpad controller. Place a level on the floor of the coach to ensure a level reference point in the coach. Press “LEVEL Coach” on the touchpad. Fig. 35 The next screen that follows (Fig.
Page 21
Push "EXTEND REAR" (Fig. 36D) button until jacks contact the ground and lift rear of coach. Keep button depressed until the carpenter's level bubble is centered. Push "EXTEND DRIV SIDE" (Fig. 36B) and "EXTEND PASS SIDE" (Fig. 36C) buttons until level bubble is centered.
Installing the Aluminum Crossbars NOTE: Aluminum (shown below) or Steel crossbars are required and mount to the front two jacks. Use two 1/4" - 20 x 1" bolts (Fig. 37C) with two 1/4" - 20 nuts (Fig. 37D) per light. Install the bolt through the holes in the ends of the lights, into the crossbars and attach the nuts.
Installing the Steel Front Crossbar NOTE: Crossbar must be installed between the Passenger Side and Driver's Side jacks. Slide the inner crossbar beam (Fig. 41A) into the outer crossbar beam. (Fig. 41B). With the backside of the flanges of the crossbar mounting "L" brackets facing the front of the vehicle (Fig.
Page 24
Fasten the crossbar bracket curbside to the jack bracket using two 1/2" - 13 x 4" bolts (Fig. 44A) and 1/2" - 13 lock nuts (Fig. 44B). Tighten to 90 ft/lbs. Repeat with the driver's side crossbar bracket and jack bracket (Fig. 45A, Fig. 45B). Fig.
Troubleshooting Manual Override - Jacks 5/32 In the event that the jacks will not extend or retract, the valves can be manually overridden by using a ” 5/64 " hex wrench to turn the manual override clockwise on the valve. (Fig. 47). The leveling jacks can then be extended or retracted.
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. In colder temperatures (less than 10° F) the jacks may extend and retract slowly due to the fluid’s molecular nature.
Solutions to Possible System Errors What Is Happening? Why? What Should Be Done? Coach ignition not in Turn ignition to RUN position. RUN position. Parking brake not set. Set parking brake. System will not turn on. Controls have been on for more than four minutes Tap screen or turn ignition off and then back on.
