before motor stops may result in
continued motion in same direction.
This winch has a drag brake that
stops and holds the full working
load on the first layer of wire rope
closest to drum. Each additional
layer of wire rope reduces brake
capacity approximately 10%. When
powering the winch in, the brake is
disengaged and does not activate
until the motor is turned off and
the load tries to pull the wire rope
off the drum. When the winch is
powered out, as in releasing a load,
the brake is engaged and the motor
must over power the brake to
rotate the drum. Powering against
the brake will cause heat to build
up in the drum and may transfer
heat to the wire rope. Cable-Out
operation should be limited to 5
minutes of continuous operation.
Cool-down may take 30 minutes.
Brake is disengaged during Cable-In
operation so pulls may be per-
formed immediately after reeling
out rope.

FREEWHEEL
Rotate the clutch lever to the
"Free" position as shown in Figure
8. If there is a load on the wire
rope, the clutch lever may not turn
easily. Release tension on the wire
rope by jogging out some of the
rope then try releasing the clutch.
Rope can now be pulled off drum.
A drag mechanism prevents back-
lash to keep rope from snarling. To
reengage drum, rotate the clutch
lever to the "Engaged" position
(Figure 8).

freewheel lever.
Do not release clutch when winch is
under load. Release tension on wire
rope by jogging out some rope.
Never engage clutch lever while
drum is turning. This may damage
winch or wire rope.

OPERATING HINTS
1. Do not put angular loads on
winch. Whenever possible, pull
should be perpendicular to
winch.
2. Keep wire rope under tension
when operating winch so it
remains tight and even on drum.
3. Replace wire rope when frayed.
EXTENDING LIFE OF WINCH
1. KEEP A TIGHTLY WOUND WIRE
ROPE DRUM. Do not allow wire
rope to become loosely wound. A
loosely wound spool allows wire
rope under load to work its way
down into layers of wire rope on
drum. When this happens, wire
rope may become wedged within
body of windings, damaging wire
rope. To prevent this problem,
keep wire rope wound tightly
and evenly at all times. A good
practice is to rewind wire rope
under tension after each use.
2. DO NOT ALLOW MOTOR TO
OVERHEAT. During long or heavy
pulls, motor and gearbox will
get hot.
3. USE A PULLEY BLOCK FOR HEAVY
LOADS. To maximize winch and
wire rope life, use pulley block to
double line heavier loads.
4. AVOID FREQUENT STOPPING
AND STARTING A PULL. The pull
required to start moving a load
is greater than pull to keep it
moving.
5. MINIMIZE AMOUNT OF TIME
IN REVERSE (CABLE-OUT) DIREC-
TION. Drag brake is always in
friction when powering wire rope
off drum. Using freewheel opera-
tion and pulling rope off drum
minimizes brake wear.
6. TRY TO WINCH ON WIRE ROPE
LAYER CLOSEST TO DRUM. The
more wire rope that is on drum,
the harder winch has to work to
move load. Plan winching tasks to
minimize amount of rope on
drum but do not winch with less
than 5 turns of rope on drum.
7. PREVENT KINKS BEFORE THEY
OCCUR (See Figure 9).

(a) This is the start of a kink. At this
time, the wire rope should be
straightened.
(b) The wire rope was pulled and
the loop has tightened to a kink.
The wire rope is now perma-
nently damaged and must be
replaced.
(c) Kinking causes the wire strands
under the greatest tension to
break and thus reduces the load
capacity of the wire rope. The
wire rope must be replaced.
M A I N T E N A N C E
Perodically check the tightness of all
mounting bolts.
LUBRICATION
Winch is lubricated for life at facto-
ry. It is unnecessary to grease or oil
any part of winch at any time. If
relubrication is necessary (after
repair or disassembly) only use
factory approved grease (See
Replacement Parts List).
