TECHNIQUES OF 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 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 cable.
The Dow-lok® clutch provides freespooling and clutch engagement with the cable drum. With the clutch disen-
gaged, the cable can be freespooled off the drum. For winching in the load, the clutch must be fully engaged with the
drum.
Notches on the shifter shaft engage the bracket to positively latch the Dow-lok® clutch in the engaged, “IN” position
or disengaged, “OUT” position.
TO DISENGAGE CLUTCH raise handle so notch clears bracket. Pull handle out and latch the shaft notch onto bracket.
DO NOT ATTEMPT TO DISENGAGE WITH A LOAD ON THE WINCH.
TO ENGAGE CLUTCH raise handle so notch clears bracket. and push handle in as far as it will go. The clutch will
automatically spring into engagement and latch when the clutch aligns with the drum shaft. In order to attain full en-
gagement, internal elements of the clutch MUST be aligned. This alignment will take place when cable drum or cable
drum shaft turns a maximum of 1/4 revolution.
DO NOT ATTEMPT TO LIFT A LOAD UNLESS NOTCH IN SHIFTER SHAFT IS SECURELY LATCHED. KEEP CLEAR OF
SPRING LOADED HANDLE DURING AUTOMATIC ENGAGEMENT.
The air-shifter clutch allows rapid unspooling of the cable, from cable drum, for hooking onto load. The air shifter
requires a separate, regulated air supply of 60-90 PSI. The clutch is operated by an air-cylinder as follows:
TO DISENGAGE CLUTCH run the winch in the reverse “OUT” direction until the load is off the cable. Apply 70-90 PSI
to inlet port fitting of air cylinder.
TO ENGAGE CLUTCH remove air pressure from air cylinder. Run the winch in reverse “OUT” direction until the cable
drum starts turning. After the clutch is fully engaged, the winch is ready for winching in the cable.
WARNINGS
• CLUTCH MUST BE TOTALLY ENGAGED BEFORE STARTING THE WINCHING OPERATION.
• DO NOT DISENGAGE THE CLUTCH UNDER LOAD.
• DO NOT LEAVE CLUTCH ENGAGED WHEN WINCH IS NOT IN USE.
• STAY OUT FROM UNDER AND AWAY FROM RAISED LOADS.
• STAND CLEAR OF CABLE WHILE PULLING. DO NOT TRY TO GUIDE CABLE.
• DO NOT EXCEED MAXIMUM LINE PULL RATINGS SHOWN IN TABLE.
• DO NOT USE WINCH TO LIFT, SUPPORT, OR OTHERWISE TRANSPORT PEOPLE.
• A MINIMUM OF 5 WRAPS OF CABLE AROUND THE DRUM BARREL IS NECESSARY TO HOLD THE LOAD. CA-
BLE ANCHOR IS NOT DESIGNED TO HOLD LOAD.
