WARNING:
THE MANUAL RETRACT WINCH IS
EQUIPPED FOR MANUALLY RETRACTING THE ROOM
ONLY. IT IS NOT TO BE USED FOR LIFTING OR ANY
OTHER APPLICATION. HIGH FORCES ARE CREATED
WHEN USING A WINCH, CREATING POTENTIAL SAFETY
HAZARDS. FAILURE TO FOLLOW ALL CAUTIONS AND
INSTRUCTIONS MAY CAUSE FAILURE OF THE MANUAL
RETRACT WINCH OR CONNECTIONS RESULTING IN
DAMAGE OR PERSONAL INJURY. MAINTAIN FIRM GRIP
ON THE WINCH HANDLE AT ALL TIMES. NEVER RELEASE
THE HANDLE WHEN RATCHET LEVER IS IN THE OFF
POSITION AND THE WINCH IS LOADED. THE WINCH
HANDLE COULD SPIN VIOLENTLY AND CAUSE PERSONAL
INJURY. CHECK THE WINCH AND STRAPS FOR DAMAGE
OR WEAR, AND CHECK FOR PROPER RATCHET OPERATION
ON EACH USE OF THE WINCH. DO NOT USE IF DAMAGED
OR WORN.

MANUAL ROOM RETRACT PROCEDURE
Refer to the
SOLENOID VALVES
NOTE : The "T" HANDLE may turn easily at first but
will become more difficult to turn as an internal spring is
compressed. Be sure to open both valves completely
(about six turns of the "T" HANDLE).
NOTE : The room may move slightly as the SOLENOID VALVES
are opened and internal pressure is released.
4. Locate the MANUAL RETRACT WINCH and connect it to
the room according to the vehicle manufacturer's instructions.
To extend the WINCH STRAP firmly grasp WINCH HANDLE,
place RATCHET LEVER in its OFF position, and slowly rotate
the WINCH HANDLE counterclockwise, keeping a firm grip on
the handle. When enough WINCH STRAP is extended, place the
RATCHET LEVER in its ON position and slowly rotate the WINCH
HANDLE clockwise until the RATCHET LEVER locks.

5. Slowly winch the room in by turning the WINCH HANDLE
clockwise. The RATCHET LEVER should produce a loud, sharp,
clicking noise.
NOTE : Winching the room in quickly will raise pressure in the
hydraulic fluid and make winching more difficult.
WARNING:
OPERATE THE MANUAL RETRACT WINCH
BY HAND POWER ONLY. IF THE WINCH CANNOT BE
CRANKED EASILY WITH ONE HAND IT IS PROBABLY OVER-
LOADED. IF WINCHING BECOMES TOO DIFFICULT STOP
AND CHECK FOR OBSTRUCTIONS OR RESTRICTIONS ON
THE ROOM AND ROOM EXTENSION MECHANISM.
6. When the room is fully retracted, engage the room locking
devices. Leave the retract winch in place.
WARNING:
THE ROOM EXTENSION SOLENOID VALVE
"T" HANDLES MUST BE IN THE OPEN POSITION WHEN THE
MANUAL RETRACT WINCH IS ENGAGED.
7. The system should be repaired before using again.
