pushed. The panel will not turn on if the park brake is not set.
2. Place the ignition switch in the "ACC" position.
The vehicle’s engine must be off. Running the engine during
or after leveling may inflate the air suspension lifting the
vehicle out of level.
3. Push the "ON" button on the light plate. The POWER ON
light will be lit.
4. Push and hold the "DUMP" button until all air is exhausted
from the vehicle’s suspension system.

settling of jacks or vehicle, equipment malfunction etc.
If parking on soft ground or asphalt paving, wood blocks or
pads should be placed under the jacks.
Refer to the vehicle owner’s manual for proper operation of
room extensions.
IMPORTANT: Do not use a room extension support when
the vehicle is supported by the leveling system.
5. Move the FRONT and REAR STORE LEVERS to the
OPERATE POSITION. Nothing should happen at this time.
Place pads under jacks if necessary at this time.
NOTE:
The respective RED WARNING LIGHT will come on
when a jack is extended 2 or more inches.
6. A lit yellow LEVEL light indicates that the end, side or
corner of the vehicle is low. Only one yellow LEVEL light
should be lit at a time. If a corner of the vehicle is low a side
LEVEL light will be on by itself.
Move the JACK CONTROL LEVER to the EXTEND position
to extend jack pairs corresponding to a lit yellow light. Extend
jack pairs accordingly until all yellow lights are out. It may
take several movements from side to front, or side to rear to
raise a low corner. If the ground is too uneven, the jacks may
not have enough stroke to level the vehicle. The vehicle may
have to be moved. NOTE:
7. After the vehicle is level, the jacks not used for leveling
may be extended until they touch the ground. This provides
additional stability against wind and activity in the vehicle.
Do this by pushing the jack control lever to the rear and/or
front as needed to extend any remaining jacks. Do not use
the right or the left extend positions. Jacks used to stabilize
the vehicle should lift the vehicle 3/4" to 1" after touching the
ground.
8. Push the "OFF" button on the light panel.

MAINTENANCE
.
OIL LEVEL
All maintenance should be done as part of the normal
servicing of the coach.
The oil level should be within one inch of the top of the
reservoir. Most breather caps have a dipstick. Fluid level
should be between the bottom of the dipstick and the
The oil level should be checked when the vehicle is first
center mark.
purchased and then once every two years. More often if
there is an oil leak in the system.
NOTE: Overfilling the tank can cause leakage of oil
through the breather cap.
Any HWH hydraulic equipment, including jacks, slide-outs
and steps should be fully retracted before checking fluid
level. The oil reservoir is part of the pump / manifold
assembly. The oil level is checked and filled through the
breather cap. Clear any dirt away from the breather / filler
cap before removing.
FLUID:
HWH Specialty Hydraulic Oil is recommended. In an
emergency Dexron automatic transmission fluid can be used
NOTE:
Dexron automatic transmission fluid contains red dye
and can cause staining should a leak occur. DO NOT USE
brake fluid or hydraulic jack fluid. Use of these can damage
seals.
ELECTRICAL SYSTEM
The batteries should be in good condition and fully charged.
All electrical connections, especially ground connections,
should be clean, tight, free from corrosion and protected
from corrosion. Weak batteries can cause erratic operation.
Battery cable terminals, battery posts and connections
should be kept clean and protected from corrosion.
UNUSUAL CONDITIONS
If driving conditions are unusually muddy, the jacks may
become caked or clogged with mud. This condition may
hamper the proper operation of the leveling system. This
problem may be prevented or remedied by cleaning off each
leveling jack if they become excessively muddy.
In west or icy weather leveling jacks may become encrusted
with ice. This may cause the leveling system to function
improperly. To eliminate this problem, periodically check the
leveling jacks and break loose any ice which may be
causing improper operation.
Do not move the vehicle while the leveling jacks are still in
contact with the ground. Place the system in the store mode
and then visually check to see if the leveling jacks have
returned to the STORE/TRAVEL position.
NOTE: All major components of the system can be replaced
with rebuilt parts or can be sent to HWH CORPORATION to
be rebuilt, when the system is out of warranty.
LEVEL SENSING UNIT ADJUSTMENT
Level the vehicle by placing a circular bubble level in the center of the freezer floor or location within the vehicle that
is to be level. With the vehicle level, adjust the sensing unit until all yellow lights are off. This is done by drawing up
the corresponding screw if the sensing unit is mounted below the surface as shown or backing out the corresponding
screw if the sensing unit is mounted above the surface. Bump the sensing unit to see that it is settled tight against all
three screw heads and still indicates that the unit is level.
