To temporarily wire the winch to a 12V
battery:
1. Plug the power cable into the cor-
responding plug socket on the winch.
Route the power cable from the winch
to your battery, being careful to avoid
getting it tangled with the other wires or
causing a tripping hazard.
2. Connect the red alligator clip to the
positive (+/RED) terminal of your bat-
tery. Use only a 12V battery source that
is in good working condition. Connect
the black alligator clip to the frame of
your vehicle to establish a ground con-
nection.
3. Plug the remote control switch into the
second plug socket on the side of the
winch. This remote switch allows the
winch to be operated from a safe dis-
tance.
4. Set the remote control aside in a safe
place until the winch is ready to oper-
ate.
To permanently wire the winch to a 12V
battery:
The included power cable can be used for
a permanent wiring set-up; however, the
alligator clips must be replaced with suit-
able connectors (not included) to allow the
red wire to hook up to a positive 12V power
source and the black wire to connect to the
vehicle frame. Route the wires through the
vehicle in a way that will prevent damage
to the wires during operation and mainte-
nance of the vehicle.
Important Wiring Reminders
1. Always wear ANSI approved safe-
ty glasses when operating the
winch or working near the 12V
battery.
2. Always connect the positive (+/
RED) cable to the positive (+/
RED) battery post and the nega-
tive (-/BLACK) cable to the vehi-
cle frame.
3. Always connect the red alligator
clip to the battery FIRST, followed
by the black alligator clip to the
vehicle frame.
4. Never run the battery dead while
using the winch.
5. Never use a battery that is leaking
acid or is badly corroded.
Failure to comply with these and
other warnings could result in seri-
ous personal injury.
If holes are drilled into metal to route
the power cable, be sure to use rubber
grommets to protect the cable from
being cut on the sharp metal.

NOTICE
Mounting
Receiver Hitch
The receiver hitch is designed to be mount-
ed to a standard truck step bumper. The
vehicle and bumper must have a minimum
towing capacity of 2000 lbs. The receiver
accepts a standard 2" draw bar.
To install the receiver hitch:
1. Temporarily clamp the receiver hitch to
the truck bumper with C-clamps.
2. Use the holes in the receiver hitch as a
guide for drilling four 1⁄2" mounting holes
into the bumper.
Note: Avoid drilling into any wiring that
may be routed through the inside of the
bumper.
DO NOT weld or drill additional holes
in the hitch. This will weaken the
hitch and may cause it to break.

This winch has a pulling capacity of 2,000
lbs. Applying this capability to a practical
sense, you can:
• Move a load from a “dead” stop of up to
2,000 lbs. on level ground.
• Move up to a 4,800 lb boat in water.
• Maintain movement of a wheeled vehi-
cle of up to 6,000 lbs.
Pulling capacity is reduced as the incline
increases. For example, maintaining vehi-
cle movement capacity is reduced from
6,000 lbs. on flat ground to 1,100 lbs. on
a 45° incline. Please refer to Figure 4 for
estimated pulling capacity (maintaining
vehicle movement) on various inclines.
Figure 4. Pulling capacity chart.

end of the hand crank over the flattened
end of the threaded shaft (see Figure
5).
3. Replace the outer hex nut and tighten it
against the hand crank.
4. Rotate the hand crank clockwise to
tighten the cable. Turn until the cable
has been completely retracted.
Figure 5. Hand crank.

H7604 2000 Lb. Electric Winch -11-
5. Retighten the clutch knob and tighten
the inner hex nut.
6. Attach the power cord to the 12V bat-
tery.
7. Stand clear of the cable. Use the remote
control to turn the winch ON and begin
retracting the cable.
Maintenance
Occasionally examine the cable for
any fray or other damage. Damage
to the cable can significantly
reduce the pulling capacity and will
increase the likelihood of breaking
under load. This could cause seri-
ous personal injury.
1. Occasionally lubricate the cable with a
light machine oil.
2. Grease the gears every 6 months.
Separate the left and right housing to
expose the gears. Use a good quality
waterproof grease.
Never use the hand crank to assist
the operating winch. This will dam-
age the winch and may cause seri-
ous personal injury. Never wrap the cable around an
object and attach the hook to the
cable. This can damage the object
and fray or kink the cable. Should
the cable or pulling object break,
serious personal injury could occur.
Winch
To operate the electric winch:
1. Place the vehicle in low gear (manual
transmission) or Park (automatic trans-
mission). Put your emergency brake
ON and block the wheels with suitable
chocks.
2. Attach the power and control cables to
the winch.
3. Unlock the cable by turning the clutch
knob counterclockwise, then pull out
the amount of cable you need. Always
leave at least three turns of cable on
the winch to prevent it from slipping off
under initial tension.
4. Hook onto the pulling object using a
pulling point, tow strap, or chain as
shown in Figure 6.
