Manual Leveling with Hydraulic Jacks
You may encounter conditions where automatic leveling of
the motorhome cannot be accomplished. If possible, retract
the jacks and re-position the motorhome to a more level
parking area. If that is not possible or feasible, try leveling the
motorhome manually by deploying the jack rams in pairs.
1. Follow all hydraulic leveling system safety precautions
before and during operation of the leveling system.
2. Start the motorhome’s engine, ensuring the parking
brake is engaged and the transmission is in:
a. Neutral for Class A Diesel Pushers;
b. Park for Class A and Class C front engine gas or
diesel motorhomes.
3. Press the ON button on the Leveling Jacks Control Panel.
4. Press either the FRONT or REAR button on the Control
Panel. Depending on which switch is pushed, either the
front or rear pair of jack rams will deploy. Release the
switch when the jacks contact the ground (you should
feel the motorhome slightly rise).
5. Press the opposite switch and hold until the motorhome
rises slightly. Watch the control panel for an indication
that the motorhome is level front-to-back.
6. Press either the LEFT or RIGHT button on the Control
Panel (this will move the le or right-side pair of jack
rams). Watch the control panel to determine if the con-
troller can sense that the motorhome is level le-to-right.
7. If needed, press the opposite side switch while watching
the control panel for an indication that the motorhome
is level le-to-right.
8. Repeat this process, FRONT-to-BACK and LEFT-to-
RIGHT until the controller indicates the motorhome
is level.
9. Turn OFF the Leveling Jack Control Panel; turn off
the motorhome’s engine, while keeping the parking
brake engaged.
IMPORTANT: Never completely li a wheel or wheels
off the ground with the leveling jacks. This creates an
unstable situation. Try manually adjusting the jacks or
re-position the motorhome to a more level area so that
all wheels remain in contact with the ground when the
motorhome is leveled.
NOTE: Jacks always operate in pairs, i.e., Right Pair, Left
Pair, Front Pair, Rear Pair. Pushing the corresponding
control button operates both jacks.
Zero Point Calibration
e hydraulic leveling system was calibrated at the factory
with an unloaded vehicle. This is known as Zero-point
calibration and is the point where the system will return the
jacks when an auto-leveling cycle is initiated.
Vehicle loading and other factors can make it necessary
to re-calibrate the Zero-point. Refer to the manufacture's
operation guide for further information regarding calibration
and maintenance procedures.
NOTE: Complete manufacturer’s instructions regarding
the operation, maintenance and system diagnostics of the
hydraulic leveling system installed on your motorhome
are available through your on-line TMC Owners Re-

Hydraulic Fluid Recommendations for
LCI Leveling Systems
Operating conditions:
The following automatic transmission fluid (ATF) rec-
ommendations for use in Lippert Components, Inc. (LCI)
hydraulic systems are based upon hydraulic system operation
in various environmental air temperatures.
1. Above Freezing - Operation at air temperatures routinely
above 32 °F (0 °C)—above freezing—which also covers
most initial OEM lls.
a. Dexron® III/Mercon® ATF
b. Super ATF from Phillips 66
c. Mercon® V ATF
d. Dexron® VI ATF
e. PetroBlend (Mason City, IA) PHO 0022S (synthetic
group 3 base blend)
f. Bellman all temp 22 (Bremen, IN)
g. Or any ATF or hydraulic uid with a pour point
lower than -44 °F (-42 °C).
2. Below Freezing - Operation at air temperatures routinely
below 32 °F (0 °C)—below freezing.
a. Mobil 1™ full synthetic ATF
b. Royal Purple® full synthetic ATF
DO NOT use ATF Type F fluid. Type F ATF is not
compatible with LCI hydraulic system seals.
Seals will not work properly.
