ASSEMBLY OF WINCH
WARNING: Before installing this winch, disconnect the vehicle ground and positive
leads from the battery.
WARNING: CHEMICAL AND FIRE HAZARD. Failure to observe these instructions
could lead to severe injury or death.
Always remove jewelry and wear eye protection.
Never lean over battery while making connections.
Always verify area is clear of fuel lines, fuel tank, brake lines, electrical wires, etc when drilling.
Never route electrical cables:
1. Across any sharp edges.
2. Through or near moving parts.
3. Near parts that become hot.
Always insulate and protect all exposed wiring and electrical terminals.
Always install terminal boots as directed.
Always choose a mounting location that is sufficiently strong to withstand the maximum pulling
capacity of the winch.
NOTE: The wire cable has been installed on your winch under minimal load at the factory. The
wire rope must be re-spooled onto the drum under load so that the outer layers will not draw down
into the inner layers, damaging the wire rope.
Step (1)
Install mounting kit or prepare a flat, secure mounting location for the winch. Carefully follow the
instructions included with the mounting kit.
NOTE: If you manufacture your own mounting plate it should have at least 1/4in. thickness.
Fasteners should be steel high-tensile grade 5 or better. A poorly designed mount may void warranty.
If you choose not to use a mounting kit, you will need to drill holes in the structural support of your
vehicle. Be certain that your structural support will stand up to the rated pulling forces of this winch.
Step (2)
Position the winch over the holes in the mounting kit or structural support.
Step (3)
Secure winch to mounting kit or structural support using bolts, washers and nuts supplied.

NOTE: In order to gain access to the hardware directly underneath the cable drum it may be
necessary to unspool the cable from the winch drum.
LUBRICATION
All moving parts in the winch are permanently lubricated with high-temperature lithium grease at the
time of assembly. Under normal conditions factory lubrication will suffice. Lubricate cable periodically
using light penetrating oil. Inspect for broken strands and replace if necessary. If the cable becomes
worn or damaged, it must be replaced.
PREPARING THE CABLE FOR INSTALLATION
Unwind the new cable by rolling it along the ground to prevent kinking. Remove old cable and
observe the manner in which it is attached to the drum flange.
MOUNTING THE CONTROL BOX
The control box can be mounted in various ways depending on the application. What follows are the
manufacturer’s recommendations, which shows the steps to attach the control box to the winch
motor base.

CAUTION: When attaching wires to the motor or solenoid terminals, hold the inner nut with
a wrench while tightening the outer nut with a second wrench. Do not allow the terminals to rotate in
their housings. Rotation may cause internal wire damage or part misalignment.
For normal self-recovery work, your vehicle’s existing electrical system is adequate. A fully charged
battery and proper connections are essential. Run the vehicle engine during winching operations to
keep battery charged.
Pay close attention to proper electrical cable connection as follows (refer to Diagram 1)
1. Short Red cable (B') connects to the red terminal (B) of the motor.
2. Short black cable with yellow jacket (C') connects to the yellow terminal (C) of the motor.
3. Short black cable with black jacket (D') connects to the black terminal (D) of the motor.
4. Thin black cable (E) connects to bottom terminal (A) of the motor.
5. Long Black Cable (1.8m), one terminal connects to the bottom terminal (A) of the motor, and
the other terminal negative (-) connects to negative (-) terminal of battery.
6. Long red cable positive (+) connects to positive (+) terminal of battery.

Diagram2: Principle of power works
NOTE:
1. Your battery must be kept in good condition.
2. Be sure battery cables are not drawn across any surfaces, which could possibly damage
them.
3. Corrosion on electrical connections will reduce performance or may cause a short.
4. Clean all connections especially in remote control switch and receptacle.
5. Use a silicone sealer to protect from corrosion in marine environments.
6. Index the heads of the plate studs into the keyhole slots on the back of the winch.
7. Attach the winch/adaptor plate assembly to your trailer hitch by inserting the trailer hitch ball
through the receiver in the adaptor plate.
OPERATING YOUR WINCH
Read the following carefully before attempting to operate your winch and keep the instructions for
future reference.
1. 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 to the center of the vehicle. After the job is done you can
un-spool and rewind for a neat lay of the cable.
2. Store the remote control switch inside your vehicle where it will not become damaged and
inspect before you plug it in.
3. When ready to begin spooling in, plug in remote control switch with clutch disengaged. Do
not engage clutch with motor running.
4. Never connect the hook back to the cable; this causes cable damage. Always use a sling or
chain of suitable strength.
5. Observe your winch while in operation, if possible while standing at a safe distance. Stop the
winching process every 3 feet or so to assure the cable is not piling up in one corner.
Jamming the cable can break your winch.
6. Do not attach tow hooks to the winch mounting apparatus. They must be attached to vehicle
frame.
7. The use of a snatch block will aid recovery operations by providing a doubling of the winch
capacity and a halving of the winching speed, and the means to maintain a direct line pull to
the center of the rollers. When double loading during stationary winching, the winch hook

Page of 15
8
should be attached to the vehicle frame.
8. Ensure rated “D” or bow shackles are used in conjunction with an approved tree trunk
protector to provide a safe anchor point.
9. When extending winch cable, ensure that at least FIVE (5) wraps of cable remain on drum at
all times. Failure to do so could result in the cable detaching from the drum under load,
causing serious personal injury or property damage.
10. All winches are provided with a red cable marking to identify that 5 cable wraps remain on
the winch drum; when this mark appears at the rollers, no recovery should be attempted
beyond this marking.
11. Since the greatest pulling power is achieved on the innermost layer of your winch, it is
desirable to pull off as much line as you can for heavy pulls; however, you must leave 5
wraps minimum on the drum, to the red cable marking. If this is not practical, use a snatch
block and double line arrangement.
12. Neat, tight spooling avoids cable blinding, which is caused when a load is applied and the
cable is pinched. If this happens, alternately power the winch in and out. Do not attempt to
work a bound cable under load; free by hand.
13. Apply blocks to wheels when vehicle is on an incline.
14. Battery:
Be sure that the battery is in good condition. Avoid contact with battery acid or other
contaminants.
Always wear eye protection when working around a battery.
Have the engine running when using the winch, to avoid depleting the battery.
15. Winch cable:
Be sure that the cable is in good condition and is attached properly.
Do not use the winch if cable is frayed.
Do not move the vehicle to pull a load.
Do not replace the cable with a cable of lesser strength.
The life of cable is directly related to the use and care it receives. Following each use, a cable
must be wound onto the drum under a load of at least 500 lbs. (230kg) or the outer wraps will
draw into the inner wraps and severely damage the cable during winching. The first winch use
should be a familiar run while in a relaxed, non-recovery situation. Spool out the cable until the
red cable mark appears (about five wraps on the drum), then rewind the cable onto the drum
under a load of 500 lbs. (230kg) or more. This will slightly tension and stretch the new cable and
create a tight cable wrap around the drum. Failure to do so may result in cable damage and
reduced cable life.
When the cable is replaced, apply a drop of thread bonder to seal the threads and prevent
leakage. Tighten the clamp screw properly but do not over-tighten. The clamp thread will
prevent loosening of the screw in arduous conditions.
When replacing the steel wire rope, be sure to disconnect the winch cable to “+” (positive) of the
battery, and disengage the clutch by move the clutch handle to the “OUT” position.
16. Do not attempt to exceed the pulling limits of this winch.
17. Do not drive your vehicle to assist the winch. Vehicle movement in combination with winch
operation may overload the cable, the winch itself or cause damaging shock loads.
18. Shock loads when winching are dangerous! A shock load occurs when an increased force is
suddenly applied to the cable. A vehicle rolling back on a slack cable may induce a
damaging shock load.
19. The winch shown in this manual is solely for vehicle and boat mounted, non-industrial

Page of 15
9
applications.
20. Do not use winch in hoisting applications due to required hoist safety factors and features.
21. Do not use the winch to lift, support or otherwise transport personnel.
22. Never operate your electric winch in a gas station or any place where explosive gasoline
fumes are present.
23. This winch uses DC power.
DAY-TO-DAY USE OF YOUR WINCH
The best way to get acquainted with how your winch operates is to make a few test runs before you
actually need to use it. Plan your test in advance. Remember you can hear your winch as well as
you can see it operate. Learn to recognize the sound of a light steady pull, a heavy pull, and the
sounds caused by load jerking or shifting. Soon you will gain confidence in operating your winch and
its use will become second nature to you.
WARNING: Strictly obey the above steps for wire control to avoid unintentionally
engaging the radio control, which could cause serious dangers.
1. Prior to operating the winch, ensure the vehicle is secured by applying the parking brake or
chocking the wheels.
2. Pull out the winch cable to the desired length and connect to an anchor point. The winch clutch
allows rapid uncoiling of the cable for hooking onto the load or anchor point. The shifter tab
located on the gear housing of the winch operates the clutch as follows:
(A) To disengage the clutch, move the clutch shifter tab to the “OUT” position. Cable may be
free-spooled off the drum.
(B) To engage the clutch, move the clutch shifter tab into the “IN” position. The winch is now
ready for use.
3. Recheck all cable rigging before proceeding.
4. This electric winch includes an external wireless remote control.
(A) Radio control: Insert plug into the vehicle’s 12V power port. Use the handheld controller and
press button “IN” or “OUT” for wire rope in or out. The radio control system is exclusive to
each winch.
(B) Wire control:
Step 1 Connect one end of the control cable to the interface of the handheld controller;
Step 2 Connect the other end to the interface of the plug, then put the plug into the socket,
press button “IN” or “OUT” for wire rope in or out.

Radio Control Specifications:
Working Voltage 9V–12V
Frequency 433MHz
Power 10mW
Working Temperature -4oto 140 oF
Maximum Control Distance 100 ft.
5. To commence winching operation, start vehicle engine, place transmission in neutral, maintain
engine speed at idle. Never winch with your vehicle in gear or in park, which can damage
your vehicle’s transmission.
6. Never wrap the cable around an object and hook onto the cable when winching.
7. Keep hands, clothing, hair and jewelry clear of the drum area and cable when winching.
8. Never use the winch if the cable is frayed, kinked or damaged.
9. Never allow anyone to stand near the cable, or in line with the cable behind the winch while it
is under power. If the cable should slip or break, it can suddenly whip back towards the winch,
causing a hazard for anyone in the area . Always stand well to the side while winding.
10. Remove switch from 12V power port when winch is not in use.
11. Do not operate multiple winches with same frequency at the same time by remote control
within a distance of 220 feet; interference will occur among radio signals with same frequency.
12. If water enters the handheld controller, immediately remove battery and clean the circuit board
with ethyl alcohol (density required ≥98%).
13. Replace batteries in the handheld controller regularly; low voltage will affect performance.

USE OF WIRELESS CONTROL
The control handle has a 2-in-1 function. It is a wireless control as well as a cable-operating control.
Before you use the control in the wireless mode, you must install the battery to make it operational.
With the battery installed, the control will work remotely. There is no need to remove the battery
when using the cable since the attached cable overrides the remote function.
MAINTENANCE
It is highly recommended that the winch be used at least once a month. Simply power the cable out
50 feet, free spool 16 feet and then power back in. This will keep all components in good working
condition so that the winch can be relied on when needed. Contact your authorized service center
for technical assistance and repairs.
