WINCH WARNINGS AND PRECAUTIONS
WARNING –Keep hands and body away from Fairlead (cable intake slot) when
operating.
WARNING –Secure vehicle in position before using winch.
WARNING –Be certain winch is properly bolted to a structure (or vehicle) that can
hold the winch load.
WARNING –Do not use inappropriate attachments to extend the length of the
winch cable.
WARNING –Never lift people or hoist loads over people.
WARNING –Never come in between the winch and the load when operating.
WARNING –Do not apply load to winch when cable is fully extended. Keep at
least 5 full turns of cable on the spool.
WARNING –After moving an item with the winch, secure the item. Do not rely on
the winch to hold it for an extended period.
WARNING –Examine winch before using. Components may be affected by
exposure to chemicals, salts, and rust.
WARNING –Never operate winch if cable shows any signs of weakening, such
as knotting or kinking.
WARNING –Do not cross over or under cable when the winch is under load.
WARNING –Do not move your vehicle with the cable extended and attached to
the load. You could easily exceed the winch rating and snap the cable.
WARNING –Use gloves while handling cable.

4
WARNING –When the vehicle is parked on an incline you should use wheel
chocks.
WARNING –Re-spool cable properly avoiding cable misalignment.
WARNING –The winch cable must be wound onto the drum under a load of at
least 10% of the rated line pull or the outer wraps will draw into inner wraps and
damage winch cable
WARNING –Before operating the winch under load you should check proper
function of the winch by engaging and disengaging the clutch, by operating the
directional controls, and operating the speed controls. This will ensure that the winch
is working properly and will help prevent unintended damage and injury. Cycling the
winch prior to loading will also ensure the gears are properly aligned.
UNPACKING
When unpacking, check to make sure all parts are included. Refer to Assembly
Drawings and Parts List (both with the like item numbers) at the end of this manual.
INSTALLATION
1. Your 20000lb winch is designed with a bolt pattern that is standard in this class of
winch. Many winch mounting kits are available that utilize this bolt pattern for the
most popular vehicle and mounting channels. If you cannot find a kit locally, contact
us and we will provide you with the name of a dealer near you. If you utilize the
mounting channel you must ensure that it is mounted on a flat surface so that the
three major sections (motor, drum and gear housing) are properly aligned. Proper
alignment of the winch will allow even distribution of the full rated load.
2. Start by connecting the roller fairlead to the mounting channel using 2 each of the
cap screw, flat washer, lock washer and securing with nut. (Make sure the screw is
placed through the mounting channel and roller fairlead from inside the channel.
This will allow enough clearance for the winch to be placed in the channel without
obstruction.)

5
3. Mount winch to the vehicle using high strength cap screw. It should be aligned and
secured to a solid part of the vehicle (front or rear) where the full rated load will be
evenly distributed.
4. Connect the two-color (positive) battery cable from the directional valve to screw-
down positive (+) terminal to the 12/24-volt battery.
5. Please refer to installation illustration.
Mounting The Balance Valve:
The balance valve supplied is connected to motor. Be sure the balance valve’s
installing direction meets hydraulic principle chart. Otherwise, the winch will not reach
the rated line pull, and it is also dangerous for winch to power off the cable with heavy
load. If this symptom happens, simply disconnect the balance valve: exchange the oil
hole between hydraulic motor and balance valve, while your winch is working in a
different direction; change A→C1,B→C2 into A→C2,B→C1 and reconnect it. If your
order includes the balance valve should be supplied, it will have been connected with
the motor at the factory.
Plumbing Connections:
Keep all hoses away from any areas where heat may be considered too extreme such
as an exhaust manifold or turbo. Lines should not be allowed to rub on any abrasive
or vibrating surfaces. In some applications, 90°fittings on the directional valve and
motor or balance valve are necessary to make hose mounting more flexible. After
plumbing has been laid out on vehicle, install o-ring fittings supplied to valve. Torque
tight. Do not over tighten any fittings. Install o-ring fittings on Winch Motor. Torque
tight. Connect any hose port A on motor or port V1 on balance valve to port A on
directional valve, port B on motor or port V2 on balance valve to port B on directional
valve, port P on directional valve to pump’s high pressure port, port T on valve to
reservoir, if necessary Connect any hose port S on valve to steering box. Attach any
o-ring or seal from vehicles original tube fitting to tube fitting.

Caution:
The hydraulic system needs a relief valve to ensure the system safety. The absence
of such a valve could cause serious injury and damage the winch.
Winch battery cables should be placed so that there is a small amount of slack in the
cable.
If you are using a heat exchanger with your application to cool the hydraulic fluid you
should refer to the illustration about mounting.
You should check the hydraulic fluid level and replace any that may have seeped out.
The hydraulic system should be purged at this time. Listed below are the directions on
how to purge the hydraulic system.
1) Start the engine.
2) Power the winch to draw out about 5 feet of cable.
3) Shut down the engine.
4) Check the fluid level and fill as needed.
5) Repeat steps 1 through 4 as necessary.
6) Start the engine.
7) Move the cable into the desired position.
8) Turn the wheels on the vehicle from the right lock to the left lock positions five
times to help bleed the hydraulic system.
9) If the hand control unit is working backwards, simple exchange the brown and
the white wire connections within the valve.
Test the winch for proper operation. Refer to the section below.
OPERATION
WARNING
1 Make sure clutch is totally engaged before starting any winch operation;
2 Stay clear and away from raised loads;
3 Stay clear of cable while pulling do not try to guide cable;
4 A min. of 5 wraps of cable around the drum barrel.
General information:
The Winch’s standard equipment contains gear reducer, drum, hydraulic motor,
solenoid valve, switch assembly, female connector and plumbing fittings. The winch
obtains its pressure from the vehicle’s existing power steering pump or other hydraulic
power. The winch is totally sealed and can be used underwater.
There are several other ways to supply power to the winch. The first way is to use
an individual pump for engineering use. The second way is to provide the winch’s

8
hydraulic pressure is with the vehicle’s exiting power steering pump (See Installation
Instructions).
①Use a suitable individual pump, which doesn’t have an oil pressure relief valve.
It will supply pressure for both the steering box and the winch.
②Use a combined pump with an integrated oil valve. The oil valve will supply two
kinds of flow based on the difference in demand. One type of flow will be constant and
should be used with the steering system. The other will provide higher pressure and
is for engineering use.
Caution:
Hydraulic system needs a relief valve to make sure the system is safe; If there is not a
relief valve in the system; it would be dangerous and the system can’t be operated. If
your winch is driven by an existing hydraulic power system, the relief valve is also
existing.
Winch working demonstration:
1. Disengage the clutch by turning the clutch to the “Free Spool”position.
2. Grab the cable assembly and pull the cable to the desired length, then attach to
item being pulled.
Caution: Always leave at least five turns of cable on the drum; Review Winch Safety
Warnings and Precautions on page 2、3 before continuing.
3. Reengage the clutch by turning the clutch assembly to the “High Speed”or “Low
Speed”position as needed.
4. Insert the switch assembly connector onto the directional valve
5. Test-run winch in both directions. Turn the winch in each direction for about one or
two seconds meantime make the clutch totally engaged automatically.
6. Keep clear of the tow path, hold and operate the remote control supplied. Wait until
the motor stops before reversing directions.
7. When you have finished, remove the remote control from the female connector of
the directional valve and replace the female connector cover.

MaintenanceseWINCH ACCESSORIES YOU WILL NEED
NOT INCLUDED WITH YOUR WINCH
Gloves –For handling the wire rope and hook strap.
Anchor Strap/Chain –Tree saver anchor straps are made of high quality nylon with
high tensile strengths up to 15000lbs.
Heavy Blanket –place on the cable to absorb energy should the wire rope break.
RIGGING TECHNIQUES
Self-Recovery
Locate a suitable anchor such as a strong tree trunk or boulder.
Always use a sling as an anchor point. CAUTION Do not attach
the clevis hook back onto the cable as this could cause damage to
the cable. As shown in Fig 3.1
CAUTION Do not winch from an acute angle as the wire rope
will pile up on one side of the drum causing damage to wire rope
and the winch. Fig 3.2
Short pulls from an angle can be used to straighten the vehicle.
Long pulls should be done with the wire rope at a 90° angle to the
winch/vehicle.
When pulling a heavy load, place a blanket or jacket over the wire
rope five or six feet from the hook. In the event of a broken cable it
will dampen the snap back. For additional protection open the
hood of the vehicle as shown in Fig 3.3
For pulls over 70% rated line pull, we recommend the use of the
snatch block/pulley block to double line the wire rope. Fig 3.4
This reduces the load on the winch and the strain on the rope by up
to 50% depending on the included angle.

WARNING - Never use your winch for overhead hoisting or for
lifting people or moving people.
LUBRICATION
1. All moving parts within the Winch having been Lubricated using high temperature
lithium grease at the factory. No internal lubrication is required.
2. Lubricate Cable Assembly periodically using a light penetrating oil.
CABLE ASSEMBLY REPLACEMENT
If the wire rope has become worn or is beginning to show signs of strands breaking, it
must be replaced before being used again.
1. Turn clutch to the “Free Spool”position.
2. Extend cable assembly to its full length. Note how the existing cable is
connected to the drum.
3. Remove old cable assembly and attach new one in the same way as the old
cable was connected to the drum. Insert the end of the new rope and secure
the screw being tightly screwed
4. Turn clutch to the “High Speed”position.
5. Retract cable assembly onto drum, being careful not to allow kinking on the
first five wraps, then the winch cable must be wound onto the drum under a
load of at least 10% rated line pull.
WARNING - Only replace the wire rope with the identical replacement part
recommended by the manufacturer.
