NOTE:
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.
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.
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.
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.
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.

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.

The following is a list of problems, and possible solutions, which might occur to the leveling system.
NOTE:
vehicle’s suspension and electrical systems as well as an understanding of the leveling system’s hydraulic and electronics is
required.

MANUAL LEVELING SYSTEMS
A MASTER WARNING INDICATOR SHOULD ALWAYS BE USED. WHEN THE LEVELING SYSTEM HAS STRAIGHT-
ACTING JACKS A WARNING BUZZER MUST BE USED.
WHEN ONLY A RED MASTER WARNING LIGHT IS USED THE 12+ POWER FOR THE LIGHT COMES THROUGH THE
CONTROL PANEL. (SEE FIGURE 1 BELOW.) WHEN BOTH A RED LIGHT AND WARNING BUZZER ARE USED THE
+12 POWER FOR BOTH INDICATORS IS SUPPLIED BY THE IGNITION SWITCH. THE POWER MUST COME FROM
THE "ON" SIDE OF THE IGNITION SWITCH, NOT THE "ACC" SIDE. (SEE FIGURE 2 BELOW)
BY SUPPLYING IGNITION POWER TO THE WARNING BUZZER AND LIGHT, AND "ACC" POWER TO THE CONTROL
PANEL, THE SYSTEM MAY BE OPERATED IN ACCESSORY WITHOUT THE BUZZER SOUNDING. THE NEGATIVE SIGNAL
FOR THE WARNING INDICATORS MUST ALWAYS COME FROM THE CONTROL PANEL.
CAUTION: THE PURPLE WIRE IN THE MASTER WARNING LIGHT HARNESS IS HOT WHENEVER THE IGNITION
IS "ON" OR IN "ACC". THE PURPLE WIRE MUST BE REMOVED FROM THE HARNESS WHEN USING DIRECT IGNITION
