CLUTCH OP-
ERATION
To engage clutch:
1. Move the clutch control valve to the "clutch-engaged" position.
2. Anytime the temperature is below freezing, run motor in the "cable out" direction only until the drum starts to turn. In
extreme cold temperatures (below 0° F/-18° C), pull out on the cable by hand only until the drum starts to turn.
3. Wait at least 3 seconds for the clutch to fully engage, after which the winch is ready to winch in the cable.
WARNING: DO NOT ATTEMPT TO ENGAGE THE CLUTCH BY FIRST RUNNING THE WINCH MOTOR AND THEN
MOVING THE CLUTCH CONTROL VALVE TO THE "CLUTCH-ENGAGED" POSITION WHILE THE MOTOR IS RUN-
NING. DO NOT START PICKING UP THE LOAD AT THE SAME TIME THE CLUTCH IS BEING ENGAGED.
To disengage clutch:
1. Run the winch in the "cable out" direction until the load is off the cable.
2. Move the clutch control valve to the "clutch-disengaged" position.
3. The cable may now be pulled off by hand.
2 SPEED CONTROL OPERATION
Your winch is equipped with a 2-speed hydraulic motor. It is controlled by the application of 12 vDC to the Motor Control
Valve solenoid (see Typical Layout illustration above). DO NOT CHANGE MOTOR SPEED WHILE WINCH IS IN OPERATION.
LOSS OF LOAD CONTROL COULD RESULT AND/OR DAMAGE TO YOUR WINCH.
WINCH 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. Gain confidence in operating your winch and its use will become
second nature with you.
The uneven spooling of cable, while pulling a load, is not a problem, unless there is a cable pileup on one end of 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 cable.
