Introduction
"The Power Gear 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 Power Gear Electronic Leveling System to support the coach for any reason other than which
it is intended is prohibited by Lippert’s limited warranty. The Power Gear leveling system is designed as a
“leveling” system only and should not be used to provide service for any reason under the coach such as
changing tires or servicing the leveling system.
Note: This information was obtained from Power Gear manual 82-L0379 Rev OE and manual updates
dated April 2005 through May 2012.

Preparation
1. Engine must be running, the park brake must be set, and the transmission in “park” (”neutral” for diesel
coaches) for the jacks to operate.
2. Check leveling site to make sure obstructions have been cleared away for proper jack operation.
Operation
Leveling Coach
1. Turn on the ignition and start the coach. Your leveling control will start a self check sequence
indicated by the lights on the panel blinking in a rotating pattern. It will turn off when it has
finished its self check.
2. Push the ON/OFF (Fig.1A) button on the control panel. The system is now operational and ON/OFF
(Fig.1A) LED will turn on. (On some controls, there will be a 10 second wait period before operation is
allowed. During this time, the WAIT LIGHT (Fig. 1G) will flash.
Note: Check to see that the LOW VOLTAGE (Fig. 1L) light is not illuminated. If so, start the engine and wait
a few minutes to ensure that the battery voltage is good. The engine must be running for the jacks
to operate.
3. Check to see that the ENGAGE PARK BRAKE (Fig. 1M*) light is not illuminated. If so, engage the parking
brake. (Your coach will have to be in neutral or park to operate the system.)
4. Push the AUTO (Fig.1C) button. The automatic leveling system will begin its leveling procedure. Please
avoid movement in the coach during automatic leveling as it can cause errors in the results. It will
signal that it has completed the process by illuminating the center green Power Gear LEVEL (Fig.1E)
light. Check to make sure that all jacks are on the ground. Also check to make sure that no tire is off the
ground. If so, your leveling process is complete. If further adjustments are needed, or one or more tires
are off the ground, retract all jacks and refer to the “Manual Operation” section of this manual.
5. You can then turn the system off by pushing the ON/OFF (Fig.1A) button again.
Retracting Leveling Jacks
1. Turn on the ignition and start the coach.
2. Turn on the system by pushing the ON/OFF (Fig.1A) button. The system is now operational and the
ON/OFF (Fig.1A) LED will turn on.
3. Push the RETRACT-ALL JACKS (Fig.1B) button. When the JACKS DOWN (Fig.1H) light turns off, visually
check to make sure that all jacks have fully retracted. If so, your coach leveling system is ready to travel.

Manual Operation
Leveling Coach
There are certain conditions where manually leveling your coach may be desirable. Conditions where large
amounts of side to side leveling are necessary or when one or more tires are off the ground at the end of the
auto-level sequence, it may work better using the manual leveling procedures that follow:
1. Turn on the ignition and start the coach.
2. Push the ON/OFF (Fig.1A) button to turn on the system.
3. Push and hold the MAN (Fig.1D) button for 5-7 seconds in order for the system to switch to the manual
mode. It will signal that it is in the manual mode when the light under the MAN (Fig.1D) button is
illuminated.
4. Push FRONT (Fig.1F) button until the front of the coach rises at least 3”. This is important and necessary
to allow the coach to pivot when leveling side to side. If there is insufficient jack stroke to lift the front
of the coach at least 3 inches, the coach will have to be moved to an area with less front to back slope,
or a weight distribution block will have to be placed under the jack.
5. Push the REAR (Fig.1I) button until jacks contact the ground.
6. Level the coach from front to rear by pushing the REAR (Fig.1I) button if the light under the REAR
(Fig.1I) button is illuminated. If the light is illuminated above the FRONT JACKS button, push the FRONT
(Fig.1F) button. In either case, keep button depressed until the green center LEVEL (Fig.1E) light is
illuminated, or both front and rear lights are dark.
Note: The right and left rear jacks are used to level the coach side to side. Pushing the LEFT (Fig.1) button
on the control panel will extend the left rear jack. Pushing the RIGHT (Fig.1) button on the control
will extend the right rear jack.
7. Level the coach from side to side by pushing the RIGHT (Fig.1) button if the light beside the RIGHT
(Fig.1) button is illuminated. If the light beside the LEFT (Fig.1) button is illuminated, push the LEFT
(Fig.1) button until the LEVEL (Fig.1) light is illuminated.
8. Repeat steps 6 and 7 if needed.
9. Turn power off to leveling system by pushing ON/OFF (Fig.1A) button.
Note: If the Wait (Fig.1G) LED is ever flashing by itself, it means the control is busy and you cannot operate
the jacks. After a short period of time (from 5 to 30 seconds), the WAIT (Fig.1G) LED will go off again,
and you can resume operation as normal.
10. Visually inspect jack to ensure all pads are touching ground. Should one of the rear jacks not be
touching the ground, press the corresponding left or right rear jack buttons to lower the appropriate
jack to the ground. Never lift the wheels off the ground to level the coach. This can lead to an unsafe
condition and damage to the leveling system or coach.
11. If a level condition cannot be reached or one or more tires are off the ground at the completion of
leveling, retract the leveling jacks and move the coach to a different location or change its orientation
to achieve a more level starting position and repeat steps 1 through 10.
12. If a level condition cannot be obtained with the previous steps, level the coach as much as possible
while maintaining tire contact with the ground.

Rev: 11.23.22 Page 6 CCD-0004307
Manual Override
In case of a loss of power at the pump assembly, the manual override valves (MOV’s) can be used to retract
the leveling jacks. Not all Power Gear leveling system pumps have manual override valves. Power units for
double acting systems that have manual override valves have flexible rubber caps on the valves and a hex
override nut under the plastic cap on the electric motor.
To use the MOV’s:
1. Remove the PLASTIC CAP (Fig. 2A) from the end of the electric motor. You should now see a 7/16”
override nut on the end of the electric motor shaft.
2. After verifying all personnel and tools are clear of the press the rubber cap on the valve for the FRONT
LEG VALVE (Fig. 2B) The front end of the coach will start to descend. Allow coach to descend 2 inches.
3. Push and hold rubber cap on the ROADSIDE REAR VALVE. (Fig. 2D) Allow coach to descend 2 inches.
4. Push and hold rubber cap on the CURBSIDE REAR VALVE (Fig. 2C) Allow coach to descend 2 inches.
5. Repeat procedures 2-4 until the weight of the coach is transferred off the jacks and onto the
suspension and tires.
6. This procedure will retract the front legs. Using a 7/16” socket attached to a drill, spin the override nut
clockwise while holding the button on the FRONT LEG VALVE (Fig. 2B). Stop when the legs are fully
retracted.
7. This procedure will retract the roadside rear leg. After the front legs are retracted, press the button on
the ROADSIDE REAR VALVE (Fig. 2D) and spin the override nut clockwise. Stop when the leg is fully
retracted.
8. This procedure will retract the curbside rear leg. After the front legs are retracted, press the CURBSIDE
REAR VALVE (Fig. 2C) and spin the override nut clockwise. Stop when the leg is fully retracted.
9. Replace the PLASTIC CAP (Fig. 2A) on the electric motor.
Fig. 2
Care must be taken during the manual retraction of jacks to prevent bodily injury or death. The next
steps will allow uid to transfer from the legs to the reservoir. This procedure will allow the coach to
descend. Keep all personnel and equipment clear of the coach. Make sure no one is under the coach
prior to this procedure. Do not have any body parts or equipment positioned such that the coach

Maintenance
Preventative
1. Check and/or fill the reservoir with the jacks in the fully retracted position, each month. The fluid
should be one inch onto the dipstick (on models so equipped) or to the bottom of the fill port on
models without dipsticks.
2. Change fluid every 24 months.
3. Inspect and clean all hydraulic pump electrical connections every 12 months.
4. Remove dirt and road debris from jacks as needed.
5. If jacks are down for extended periods, it is recommended to spray exposed leveling jack chrome rods
with a silicone lubricant every 5 to 7 days for protection.
6. If your coach is located in a salty environment (within 60 miles of coastal), it is recommended to spray
the rods every 2 to 3 days with a silicone lubricant.
7. Grease the fitting on the bottom of each jack cylinder with Lithium grease every 20-30 uses.
8. Do not use a high pressured wash/rinse system on of the components associated with the leveling
system. This includes the pump, pump motor, wiring harness, control, and touchpad. The use of a high
pressure wash/rinse system will void the warranty.
Hydraulic Fluid Recommendation
The Power Gear Electronic Leveling System is pre-filled, primed and ready to operate direct from the
manufacturer. 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. For cold weather operation, fluid specially formulated for low temperatures may be desirable. For a
list of approved fluid specifications, see TI-188.
