all yellow lights are out.
WARNING LIGHTS:
A red WARNING light will be on whenever the corresponding jack is extended approximately 1 inch
or more provided the ignition switch is in the "ACCESSORY" or "ON"
position. Some coaches are equipped with a dash mounted master
"JACKS DOWN" light which will be on when one or more jacks
are extended, provided the ignition switch is "ON".

OPERATING PROCEDURES
SITE SELECTION
Maintain adequate clearance in all directions for vehicle,
room extensions, awnings, doors, steps, etc. Vehicle may
move in any direction due to jack extension or retraction,
ROOM EXTENSION PROCEDURES
IMPORTANT: If the vehicle is equipped with a room
extension read this section carefully.
If the vehicle is equipped with kick-down jacks, the wheels MUST
be blocked securely. Do NOT operate any room extension
until the leveling and stabilizing procedure is complete. Do
NOT retract the leveling system until all room extensions are
retracted. NEVER operate the leveling system when any
room extensions are extended.

If parking on soft ground or asphalt paving, wood blocks or

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.
NOTE: The respective red WARNING LIGHT will come
on when a jack is extended 2 or more inches.
5. 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 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.
6. 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 left extend positions.
3. Push the "ON/OFF" switch to the "ON" position.
The POWER ON light will be lit.
NOTE: If the hand/auto park brake is not set, the "NOT IN
PARK/BRAKE" light will come on when the "ON/OFF"
switch is on. The pump will not run if the park brake
is not set.
4. 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.
7. Push the "ON/OFF" switch to the "OFF" position.
8. Turn the ignition switch off.
NOTE: The leveling system should be cycled once a
month or whenever the vehicle is used, to keep the
system in operating condition.

FOR VEHICLES EQUIPPED WITH MANUAL SUSPENSION PILOT DUMP
If the vehicle is equipped with an air suspension, the air must
be dumped from the vehicle suspension before leveling the
vehicle. The vehicle will be equipped with a Manual Pilot
Dump. Refer to the vehicle owner’s manual for the proper
operation of the air dump equipment.

MAINTENANCE
OIL LEVEL
It is important that the four leveling jacks and all HWH room
extensions are fully retracted before checking the oil level.
To check the oil supply, remove the breather cap from the
top of the hydraulic reservoir. The oil level should be
approximately one inch below the top of the reservoir when
adequately filled.
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
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.
