Introduction

The four-point three-valve hydraulic leveling system is a hydraulic system which includes four points of contact utilizing either steel or aluminum jacks, and a three-valve manifold 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. Mechanical portions of the hydraulic leveling system are replaceable. Contact Lippert Components, Inc. 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.

NOTE: This manual replaces the following previously released LCI manuals: Class C Hydraulic Leveling

Owner's Manual (CCD-0001514) dated 07.19.18 and Class C Hydraulic Leveling (Weld-on) Owner's Manual (CCD-0001487) dated 06.20.18. These two manuals were consolidated into this manual.

Safety

Please read and study the operating manual before operating the leveling system.

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.

During servicing make sure that the coach is supported according to the manufacturer's

recommendation. Lift the coach by the frame and never the axle or suspension. Do not go under

the coach unless it is properly supported. Unsupported coaches can fall causing death or personal

injury or product or property damage.

Failure to act in accordance with the following may result in serious personal injury or death.

The “CAUTION” symbol above is a sign that a safety risk is involved and may cause personal injury

and/or product or property damage if not safely adhered to and within the parameters set forth

in this manual.

Moving parts can pinch, crush, or cut. Keep clear and use caution

The use of the Lippert Components, Inc. Hydraulic Leveling System to support the coach for any reason other than which it is intended, is prohibited by the Lippert Limited Warranty. The Hydraulic Leveling System is designed as a leveling system only and should not be used for any reason to provide service under the coach, e.g. changing tires or servicing the leveling system.

Lippert Components, Inc. recommends that a trained professional be employed to change the tires on the coach. Any attempts to change tires or perform other service while the coach is supported by the hydraulic leveling system could result in damage to the coach and/or cause serious injury or death.

Operation

NOTE: It is recommended that the engine idle to maintain the minimum required voltage of 12.75V DC.

The leveling system should only be operated under the following conditions:

1. The coach is parked on a reasonably level surface.

2. The coach parking brake is engaged.

3. The coach transmission should be in the park position.

4. Make sure all people, pets and property are clear of the coach while the hydraulic leveling system is

in operation.

After starting the automatic leveling cycle it is very important to not move around in the coach

until the coach is level and the green LED light illuminates in the center of the touchpad. Failure to

remain still during the leveling cycle could have an eect on the performance of the leveling system.

Selecting A Site

When the coach is parked on an excessive slope, the leveling requirements may exceed the jack lift stroke capability. If the coach is parked on an excessive slope, the coach should be moved to a more level surface before the leveling system is deployed. "EXCESS ANGLE" will appear on the LCD screen if the coach is 3.5 degrees out of level front-to-rear or side-to-side.

While utilizing leveling blocks and jack pads, all coach wheels MUST not leave the ground during

leveling. Lifting all the wheels o the ground creates a condition where severe property damage,

serious personal injury or possible death may occur.

Automatic Leveling Descriptive Logic

Grounding: The following steps describe the process of how the auto-leveling sequence extends the jacks to the ground:

1. Depending on which end of the coach is lowest to the ground, the level sensor in the controller will activate the jacks — the lowest end first, either front or rear.

A. If the rear of the coach is the lowest end, ground the lowest rear jack first. B. If the front end is the lowest end, ground the front jack closest to the power unit.

2. Ground the lowest remaining front or rear end jack.

3. Lift lowest end jacks together until level.

4. The leveling system will then ground remaining end jacks. A. If the rear of the coach is the remaining end, ground lowest jack first. B. If the front of the coach is the remaining end, ground the front jack closest to the power unit.

5. Ground the remaining front or rear remaining end jack.

6. Lift remaining end jacks together until level.

Leveling: The following steps describe the process of how the auto-leveling sequence levels the coach once

the jacks have been grounded. This process may repeat several times until level.

1. Front-to-rear

2. Side-to-side

3. Individually

4. Minor adjustments to confirm grounding

Automatic Leveling Procedure

NOTE: Coach requires 12.75V DC to commence auto-leveling function.

NOTE: Refer to Component Description listing in the System Information section for questions regarding

component locations and functions of the hydraulic leveling system.

NOTE: The engine MUST be running and the parking brake MUST be engaged for the hydraulic leveling

system to operate.

NOTE: Pressing any button during an automatic sequence will stop the sequence and a "Function Aborted" error

code will occur. Press ENTER to clear the code and then continue the operation or start a new function.

1. Press Power Button to turn system on (Fig. 1K). The green light will illuminate.

2. Press Auto Level (Fig. 1F). LCD Screen will display "Remain Still."

3. The coach will level automatically and indicate "Auto Level - Success" in the LCD display (Fig. 1E).

NOTE: Display will then read "Level - Jacks: Down." Do not press any buttons until this message appears or a

"Function Aborted" error will be displayed.

4. Visually inspect all jacks to make sure all footpads are touching the ground. If either of the rear jack footpads is not touching the ground, press LEFT or RIGHT (Fig. 1H or Fig. 1I) to lower the non-compliant jack to the ground.

Manual Leveling Procedure

NOTE: The coach should be leveled front-to-rear first and then leveled side-to-side.

NOTE: The engine MUST be running and the parking brake MUST be engaged for the hydraulic leveling

system to operate.

NOTE: Performing manual leveling on a coach requires a minimum of 9.5V DC.

1. Press Power Button (Fig. 1K) to turn system on.

2. Press the Up Arrow (Up) or the Down Arrow (Down) (Fig. 1A or Fig. 1B) to scroll through control

features until “Manual Mode” is displayed.

3. Press Enter (Fig. 1C).

4. Press Front (Fig. 1G) to extend front jacks to the ground.

5. Press Rear (Fig. 1J) to extend rear jacks to ground, then level the coach front-to-back.

6. Press appropriate Left or Right to level the coach side-to-side.

NOTE: Red lights next to the buttons on touchpad will indicate which side(s) of the coach needs to be

raised to achieve level condition.

NOTE: The front jacks will work in pairs, i.e., FRONT operates both front jacks.

NOTE: The right and left rear jacks are used to level the coach side-to-side. Pressing LEFT (Fig. 1H) will

extend the left rear jack. Pressing RIGHT (Fig. 1I) on the touchpad will extend the right rear jack.

7. Repeat steps 4-6 as needed.

8. Turn off power to leveling system by pressing the Power Button (Fig. 1K).

9. Visually inspect all jacks to make sure all footpads are touching the ground. If either of the rear

jack footpads is not touching the ground, press LEFT or RIGHT (Fig. 1H or Fig. 1I) to lower the noncompliant jack to the ground.

Automatic Jack Retract Procedures

NOTE: Pressing any button during an automatic sequence will stop the sequence and a "Function Aborted"

error code will occur. Press ENTER to clear the code and then continue the operation or start a new function.

1. Energize the system by pressing the Power Button (Fig. 1K) on the touchpad. The LCD screen will display "READY Jacks: Down."

2. Press Up Arrow (UP) or Down Arrow (DOWN) (Fig. 1A or Fig. 1B) to display "Auto Retract All" on the screen.

3. Press ENTER (Fig. 1C) to begin.

NOTE: “AUTO RETRACT” can also be commenced by pressing and holding RETRACT (Fig. 1D) for one

second.

4. The jacks will retract and shut off automatically. A. The display will read "READY - Jacks: Up." B. Press the Power Button (Fig. 1K) on the touchpad to de-energize the system. C. Perform a brief visual inspection around the coach to verify the jacks are fully retracted.
