3. All users must understand the operation of all controls and learn how to
stop the winch quickly in case of emergency.
4. Keep hands clear of the winch and steel cable when spooling the line in or
out. Hold the cable by the strap. Fingers caught in the hook or fairlead
may be pulled into the mechanism and crushed or pinched.
5. Make sure the winch is fixed to a solid support structure that can
withstand the towing capacity.
6. Never fully extend the cable while under load.
7. Do not exceed the winch load capacity.
a. Do not use the winch if damaged or it was subjected to a dynamic
shock load. Have the winch inspected and repaired by a qualified
service technician.
8. Always use proper couplings when connecting the winch cable hook,
sling, eyebolt or other accessory to the load. Never connect the hook back
to the cable. This causes cable damage. Always use a sling or chain of
suitable strength.
9. Do not use inappropriate attachments to extend the length of the winch
cable.
10. Do not lift items vertically. The winch was designed for horizontal use
only.
11. Do not pull the steel cable around or over corners.
12. Stay well away from the winch, steel cable and load when under tension.
A cable that breaks under tension can whiplash and inflict death or a
serious injury.
a. Use a winch rope dampener to absorb the cable’s energy should it
break.
13. Secure the load after moving it with the winch. Do not rely on the winch
to hold a load in position for an extended period of time. Never leave the
load unattended.
14. Apply blocks to a vehicle while connecting and disconnecting the winch
cable.
15. Observe the spooling of the cable onto the drum. Side pulls can cause the
cable to pileup at one end of the drum. To correct uneven stacking, spool
out that section of cable and move it to the other end of the drum and
continue winching. Uneven spooling causing cable pileup can interfere
with the winch tie rods causing damage to the winch.

WINCHING LIMITATIONS
There are several limitation that can affect the time duration, power consumption
and maximum weight a winch can move. A snatch block will improve the winch’s
performance. Make sure to follow all safety and operation instructions from the
snatch block’s manufacturer.
POWER
The maximum load the
winch can pull is
diminished with each
additional layer of steel
cable around the winch’s
drum. Table 1 shows the
maximum amount of
weight it can pull and the length of cable remaining on the drum.
Whenever possible, remove as much steel cable off the winch to pull with the
maximum power. Keep five wraps of steel cable on the drum at all times to
prevent the steel cable from slipping off.
Use a snatch block to move a heavier load that is
close to the winch. This will double the amount of
line outside the fairlead and increase the winch’s
pulling power at close range.
Pull a load at an angle by using a pulley attached to
a structure (Fig. 7). Both must be capable of
withstanding the load.
LINE SPEED
The heavier the load, the longer it will take the winch to move the load to the
desired location. Consult Table 2 to determine how fast the line will be drawn
into the winch.
A snatch block will halve the line speed when pulling the load.
Layer Rated Line Pull Cable Capacity
1 12,000 lb (5,443 kg) 17 ft (5.2 m)
2 9,685 lb (4,393 kg) 40 ft (12.2 m)
3 8,119 lb (3,683 kg) 65 ft (20 m)
Table 1
Fig. 7

8942724 12V DC Winch V1.0
12 For technical questions call 1-800-665-8685
POWER CONSUMPTION
The winch requires more amps to move a heavier load. Consult Table 2 to
determine the amperage consumption based on the load’s weight.
A snatch block increases a winch’s pulling power without an increase in amperage.
Using a snatch block can halve the power required.
OVERLOAD
The overload protection may kick in if the winch becomes overheated. Allow
several minutes for the winch to cool before pressing the overload reset button
to continue pulling the load.
NOTICE! Do not press and hold the reset button while winching. This can
damage the winch.
