Maintenance; Oil Level; Unusual Conditions - HWH 200 Series Operator's Manual

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.
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.
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

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.
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.
