TECHNIQUES OF OPERATION
2
The best way to get acquainted with how your winch operates is to make test runs before you actually
1
use it. Plan your test in advance. Remember to listen to your winch, as well as to watch how it
operates. Get familiar with 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 to
you.
The uneven spooling of cable, while pulling a load, is not a problem, unless there is a cable pile-up on
one end of the drum. If this happens, reverse the winch to relieve the load and move your anchor
point further toward 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 disengaged, the cable can be freespooled off the drum. For winching 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 the disengaged, “OUT” position.
TO DISENGAGE CLUTCH raise handle so notch clears bracket. Push handle in and latch the shaft notch
onto bracket.
TO ENGAGE CLUTCH raise handle so notch clears bracket. Pull handle out 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 engagement, internal elements of the clutch MUST be aligned. This alignment
will take place when cable drum or cable shaft turns a maximum of ¼ 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.
WARNINGS
CLUTCH MUST BE TOTALLY ENGAGED BEFORE STARTING THE WINCHING OPERATION.
DO NOT DISENGAGE CLUTCH UNDER LOAD.
DO NOT LEAVE CLUTCH ENGAGED WHEN WINCH IS NOT USE.
STAY OUT FROM UNDER AND AWAY FROM RAISED LOADS.
STAND CLEAR OF CABLE WHEN 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. CABLE
ANCHOR IS NOT DESIGNED TO HOLD LOAD.
WINCH MAINTENANCE
Adhering to the following maintenance schedule will keep your winch in top condition and performing
as it should with a minimum of repair.
WEEKLY
1. Check the oil level and maintain it to the oil plug level. If oil is leaking out, determine location
and repair.
2. Check the pressure relief plug in top of gear housing. Be sure that it is in good operating
condition so that hot oil gasses may escape.
3. Lubricate cable with light oil.
MONTHLY
1. Lubricate the various grease fittings located in the drum cable, end bearing, clutch housing or
operating linkage. Any good grade of moly-disulfide containing grease is acceptable.
2. Check the action of the locking ring. Make sure it is spring loaded and free to move fully
against the cable drum in the engaged position and that it is pulled fully away from the cable
drum and latched when disengaged.
3. Check the winch mounting bolts. If any are missing, replace them and securely tighten any
that are loose. Make sure to use only Grade 5 bolts or better.
4. Check alignment of chain and sprockets and adjust as required to minimize wear.
5. Inspect the cable. If the cable has become frayed with broken strands, replace immediately.
ANNUALLY
1. Drain the oil from the winch annually or more often if the winch is used frequently.
2. Fill the winch to the oil level plug with clean kerosene. Run the winch a few minutes with no
load in the direction. Drain the kerosene from the winch.
3. Refill the winch to the oil plug level with all purpose E.P. 140 gear oil.
4. Inspect frame and surrounding structure for cracks or deformation.
5. Gear wear can be estimated by rocking the drum back and forth and if necessary
drain oil and remove cover for closer inspection.

WINCH MOUNTING
It is most important that this winch be mounted securely so that the three major sections (the clutch
housing end, the cable drum, and the gear housing end) are properly aligned.
All standard model H 700 series winches are furnished with recommended mounting angles. Angle
size is ½ x 3 x 3 high strength steel angle.
CABLE INSTALLATION
The H 700 Dow-lok® winch has two tapered pockets cast into the drum. One pocket is for installations
with the wire rope wound over the drum. The other pocket is for an underwound wire rope. When
properly used, the wedge pocket design is one of the most secure anchoring methods available.
1. Unwind cable by rolling it out along the ground to prevent kinking. Securely wrap end of
wire rope opposite hook, with plastic or similar tape to prevent fraying.
2. Slide the wire rope through narrow end of the pocket against drum flange and wrap the wire
rope around the anchor “puck” and pull the wire rope and anchor back into the wide end of
the pocket. Use a soft hammer to drive the back side of the wire rope, firmly seating the
rope and anchor into the pocket.
3. Carefully run the winch in the “reel in” direction. Keeping tension on the end of the cable,
spool all the cable onto the cable drum, taking care to form neatly wrapped layers.
