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

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.

Rev: 03.17.20 Page 3 CCD-0002366

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.

Rev: 03.17.20 Page 4 CCD-0002366

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.

4. Pressing LEFT (Fig. 1H) will operate the left rear jack.

Troubleshooting

Make sure all jacks are fully retracted before travel.

Manual Override of The Power System and Jacks

In the event that the jacks do not retract, the cartridge valves can be manually overridden.

NOTE: Cartridge valves should be opened prior to operating with any auxiliary power device.

The hydraulic leveling system can be operated in conjunction with auxiliary power devices, like cordless or
power drills. In the event of electrical or system failure, the manual method of retracting the jacks can be
used. A standard hand-held drill is all that is required.

Do not over-tighten override set screws as this can damage the valves.

1. Use a

to open the valves.

2. Disconnect or shield power cables on the motor.

3. Remove plastic cap (Fig. 3A) from motor coupler.

4. Unplug the wire harness from the directional valve. See Wiring Diagram.

Automatic Safety Shutoff

The touchpad will automatically shutoff after four minutes, if left inactive. To reset the system, turn the
coach's ignition off, then back on. Press the touchpad's Power Button (Fig. 1K) again.

Drive-Away Protection System

If the ignition is in the “RUN” position, jacks are extended and the operator releases the parking brake, all
indicator lights will flash and the alarm beeper will activate. The leveling system will automatically fully
retract the jacks to clear the alarm or, if the operator resets the parking brake, the alarm will shut off.

Jacks Up Verification

If the coach's ignition is in the "RUN" position, the parking brake is released and the vehicle is in motion, the
leveling system may activate the power unit to ensure retract pressure is high enough to keep jacks fully
retracted. The LCD screen will say "JACKS UP VERIFICATION" until the retract pressure returns to normal
level. The touchpad will shut off. No beeping will occur and the "JACKS DOWN" dash light will not illuminate.

Zero Point Calibration

Before auto-leveling features are available, the Zero Point MUST be set. This is the point the system will return
to when an auto-leveling cycle is initiated. The Zero Point calibration has been set by the RV manufacturer and
verified by the RV dealer. If a new Zero Point is desired, follow the instructions in this section.

To set the Zero Point, first run a manual leveling sequence to get the coach to the desired level point. Then activate
the Zero Point configuration mode. This mode is enabled by performing the following sequence:

1. Run a manual leveling sequence to set the trailer to the desired level point.

2. Activate the Zero Point configuration mode as follows:
A. Turn off touchpad.
B. Press FRONT button (Fig. 1G) 10 times.
C. Press REAR button (Fig. 1J) 10 times.

NOTE: An alarm will sound and the display will read ZERO POINT CALIBRATION; ENTER to set,

Maintenance

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.

Rev: 03.17.20 Page 11 CCD-0002366

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.

Purging the Hydraulic System

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 or severe product or

property damage.

NOTE: Make sure jacks are fully retracted prior to filling reservoir to prevent over-filling

1. Zip-tie any loose wiring or hydraulic lines.

NOTE: The basic purge procedure to bleed the LCI Hydraulic Systems can be performed without the use of

any tools. The hydraulic system will purge the air from the hydraulic lines and cylinders by simply
running the pump.

NOTE: It is recommended to perform a minimum of three complete cycles (steps 2-7) to ensure both

proper function and adequate fluid level of the system.

2. Start with all hydraulic components in the fully retracted position, meaning all jacks and slide-outs are
brought back inside the coach as if the coach were ready for travel.

3. Find the hydraulic pump location and note the amount of fluid currently in the reservoir. The fluid level
should be about ¼” from the top of the reservoir and no more than ½” from the top.

NOTE: When checking the fluid level after ensuring all hydraulic components are retracted, note if there

are any bubbles, froth or foam on top of the fluid. This is an indication that air has been pushed back
to the reservoir when the hydraulic components were retracted in the last cycle. Wait 15-20 minutes
for the foam to dissipate before beginning the purge process.

4. If there is no froth or foam in the reservoir and the fluid is not within ½” of the top, fill the reservoir to
within the level described in step 3.

5. With the fluid level full and no foam in the reservoir, begin cycling the hydraulic system.

6. Extend jacks fully, taking the coach off the tires. If the coach has hydraulic slide-outs, extend all slide-

outs. Once all jacks and slide-outs are extended, immediately retract all slide-outs and then jacks.

7. Check the reservoir foam. If foam is present, see NOTE following step 3 and then repeat steps 4-6.
Repeat these steps until no foam is present in the reservoir. If no foam is present, the system is purged
of air.

Preventative 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 hydraulic fluid only when all the jacks are fully retracted.

NOTE: When checking the hydraulic fluid level, fill reservoir to within ¼" to ½" of fill spout.

2. Inspect and clean all power unit electrical connections every 12 months. If corrosion is evident, spray

connections with electrical contact cleaner.

3. Remove dirt and road debris from jacks as needed.

4. If jacks are extended for long 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 four to six weeks.
