MANUAL ROOM AND GENERATOR SLIDE RETRACT PROCEDURE
(WITH SOLENOID VALVES WITH VALVE RELEASE NUTS)
(USE ONLY WHEN THE ROOM WILL NOT RETRACT WITH THE ROOM CONTROL SWITCH)
OVERVIEW
The room can be retracted manually if a hydraulic or electric
failure prevents the room from being retracted using the
CONTROL SWITCH. For normal retract sequence see the
ROOM SLIDE RETRACT PROCEDURES. Refer to the
vehicle manufacturer for storage location of the winch
and information for connecting the winch to the room.
IMPORTANT: If the vehicle is not equipped with a winch,
DO NOT use other pulling devices to retract the room.
Follow steps 2 and 3 and try pushing the room in.
Contact the vehicle manufacturer or HWH Customer
Service at 1-800-321-3494 or 563-724-3396 for assistance.
CAUTION:
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.
1. Retract jacks following the LEVELING SYSTEM
RETRACT PROCEDURE.
NOTE : When manually retracting the room, make sure
the jacks are retracted before retracting the room.
2. Locate the HYDRAULIC PUMP/MANIFOLD unit.

3. Open the Solenoid Valves by slowly turning the valve
release nuts counter clockwise using the 1/4" nut driver
supplied.
IMPORTANT: Only open the valves enough to retract
the room. DO NOT turn the release nuts more than
4 and 1/2 turns. Turning the nuts more could damage
the valves.
NOTE: Prior to APRIL 2002 a 1/4" Nut Driver was sent
with the Operators Manual. As of APRIL 2002 the
1/4" Nut Driver has been incorporated into the Breather
Cap. See the back page of this manual for further info.
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
counter clockwise, 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.
CAUTION:
VALVE
WINCH BY HAND POWER ONLY. IF THE WINCH
RELEASE
CANNOT BE CRANKED EASILY WITH ONE HAND IT IS
NUT
PROBABLY OVERLOADED. 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 engaged and the solenoid
valves open.
CAUTION:
VALVE RELEASE NUTS MUST BE IN THE OPEN
POSITION WHEN THE MANUAL RETRACT WINCH IS
ENGAGED.
7. The system should be repaired before using again.
NOTE: After repairs are made, when
closing the VALVE RELEASE NUTS, do
not over tighten the nuts.
