CAUTION:
OVER-
TIGHTENING OF JAM NUT MAY STRIP NYLON SETSCREW.
MAINTENANCE
1. Inspect the rope for damage and lubricate frequently. If the rope becomes frayed with broken
strands, replace immediately.
2. Check that the clutch is fully engaging. See OPERATION instructions, above, for the appropriate
clutch shifter. FOR MANUAL CLUTCH ONLY: Monthly, disengage clutch, put several drops of oil
on the clutch handle shaft and work clutch handle IN and OUT several times to lubricate inside the
shifter assembly.
3. Check to see that the drum rope does not overrun (“birdnest”) when freespooling. Refer to page 4 if
it does.
4. Replace drum bushings and seals if seals begin to seep grease. Refer to the Overhaul Instructions,
pages 8-10. Add additional lubricant, Mobilith SHC 007, to gears and drum bearings if required.
OPERATION
The best way to get acquainted with how your winch operates is to make test runs before you actually use
it. Plan your test in advance. Remember, you hear your winch as well as see it operate. Get to recognize the
sounds of a light steady pull, a heavy pull, and sounds caused by load jerking or shifting. Avoid conditions
where load shifts or jerks occur, as they may indicate a dangerous situation.
The uneven spooling of rope, while pulling the load, is not a problem, unless there is a rope pileup on one
end of the drum. If this happens, reverse the winch to relieve the load, and move your anchor point further to
the center of the vehicle. After the job is done you can unspool and rewind for a neat lay of the rope. When
pulling a heavy load, place a blanket, jacket, and tarpaulin over the rope about five or six feet behind the hook.
In the event of a broken rope, this will slow the snap back of the rope and could prevent serious injury. The
winch clutch allows rapid unspooling of the rope, from the rope drum, for hooking onto the load. The clutch is
operated by the clutch shifter lever or air shifter.
WARNING: DO NOT DISENGAGE CLUTCH UNDER LOAD!
MANUAL CLUTCH SHIFTER
(Refer to dimensional drawing page 11):
TO DISENGAGE CLUTCH: Run the winch in the reverse (reel out) direction until the load is off the rope. Pull
handle out and rotate 90°. With handle in the “DISENGAGED” position, rope may now be free-spooled from the
drum.
TO ENGAGE CLUTCH: Pull handle out, rotate 90° and release handle. Run the winch in reverse until the
clutch handle snaps fully into the “ENGAGED” position.
DO NOT
attempt to pull a load unless the handle is
fully at the “ENGAGED” position. If manual shift indicator light is present, the green light is lit when clutch is
fully “ENGAGED”.
DO NOT
attempt to pull a load unless the green light is lit. To install light to the vehicle
electrical system refer to the Electrical Schematic on page 12.
AIR CYLINDER CLUTCH SHIFTER
(Refer to the dimensional drawing page 12):
TO DISENGAGE CLUTCH: Run the winch in the reverse (reel out) direction until load is off the rope. Apply air
pressure to the .125-27 NPT port: 5,5 bar (80 PSI) (min.)- 10,3 bar (150 PSI) (max.).
CAUTION:
PRESSURE
MUST NOT EXCEED 10,3 bar (150 PSI).
TO ENGAGE CLUTCH: Remove air pressure from the cylinder (a return spring engages the plunger). Run
winch in reverse until the clutch engagement indicator light (green light) is lit. To install light to the vehicle
electrical system refer to the Electrical Schematic on page 12.
