WARNING
CAUTION

GETTING TO KNOW YOUR WINCH
Your winch is a powerful piece of machinery. It is important that you
understand the basics of its operation and specifications so that when you
need to use it, you can use it with confidence and safety. Below is a list of
the components of your winch and their use. You should practice using
your winch before you are in a situation where you need to use it.
1.
Your EWP4500 winch is part of our new product line which has been
engineered with several patented technologies.
Motor: Your 3.2/3.9hp motor is powered by a 12/24 volt battery and provides
power to the gear mechanism which turns the drum and winds the wire rope.
Winch Drum: The winch drum is the cylinder on which the wire rope is stored. It
can feed or wind the rope depending on the remote winch switch.
Wire Rope (cable): Your winch has a 1/4"X47.6' galvanized aircraft cable
designed specifically for load capacity of 4500lbs. The wire rope feeds onto the
drum in the “under wind” position through the roller fairlead and is looped at the
end to accept the clevis hook pin.
Roller Fairlead: When using the winch at an angle the roller fairlead acts to
guide the wire rope onto the drum and minimizes damage to the wire rope from
abrasion on the winch mount or bumper.
Mechanic Gear System: The reduction gears convert the winch motor power
into extreme pulling forces.
Braking System: Braking action is automatically applied to the winch drum
when the winch motor is stopped and there is a load on the wire rope. A
separate mechanical brake applies the braking action.
Control System: Your winch was made to provide you the ability to use it in a
medley of operations. The winch can be controlled by using the Power
Cord/Switch Assembly or through a solenoid control box.
Free Spooling Clutch: The clutch allows the operator to manually disengage
(“CLUTCH OUT”) the spooling drum from the gear train, free spool. Engaging
the clutch (“CLUTCH IN”) locks the winch into the gear system.

10.Solenoid: Power from the vehicle battery flows through the weather-sealed
switch before being directed to the winch motor.
11.Remote Switch: The Power switch leads have a dual switch for powering in or
powering out your winch drum. The remote switch allows you to stand clear of
the wire rope when the winch is under load.
12.Wireless Remote Control: allow you to control winch far from 50 Ft away.
13.Universal Flat Bed Mounting Channel: Your winch could have been optionally
supplied with a flat bed mounting channel that can be mounted to most flat
surfaces such as trailers, step bumpers, truck beds, etc. The mounting channel
also has holes to accept your roller fairlead.
14.Snatch Block: If your winch is supplied with a snatch block that can double the
pulling power of the winch, or change the pulling direction without damaging the
wire rope. We recommend you to use double line and snatch block for pulling
over 70% of the rated line pull.
SAFETY PRECAUTIONS
WARNING
WARNING –Do not exceed rated capacity shown in this table.
WARNING –Intermittent use only. Allow winch to cool between uses.
WARNING –Do not use winch to lift (vertically).
WARNING –Do not use winch to pull or move people in any way.
WARNING –NEVER cut, weld, or modify any part of the winch or cable.

WARNING –A minimum of five wraps of cable around the drum barrel is
necessary for pulling and holding the rated load.
WARNING –Keep yourself and others a safe distance to the side of the cable
when it is under tension.
WARNING –The wire rope may break before the motor stalls. For heavy
loads at or near rated capacity, use a pulley block/snatch block to reduce the
load on the wire rope.
WARNING –Never step over a cable, or go near a cable under load.
WARNING –Don’t move the vehicle to pull a load (towing) on the winch cable.
This could result in cable breakage.
WARNING –Disconnect the remote control and battery leads when not in use.
WARNING –Avoid “shock loads”by using the control switch intermittently to
take up the slack in the wire rope. “Shock loads” can far exceed the rate
capacity for the wire rope and drum.
WARNING –Do not exceeds maximum line pull ratings shown on the tables.
WARNING –When re-spooling the cable ensure that the cable spools in the
under-wind position with the cable entering the drum from the bottom, not the
top.
To spool correctly you should keep a slight load on the cable while
pushing the remote button to draw in the cable. Walk toward the winch not
allowing the cable to slide through your hands. Do not let your hands get within
12″of the winch while re-spooling.
Turn off the winch and repeat the
procedure until a few feet of cable is left. Disconnect the remote control and
finish spooling by hand by rotating the drum by hand with the clutch disengaged.
Keep hands clear of the fairlead and drum while the winch is under power.
Do not use as a hoist. Do not use for overhead lifting.
Failure to heed these warnings may result in personal injury and/or property
damage.
WARNING –Use gloves to protect hands when handling the cable. Never let
the cable slide through your hands.
4

WARNING –Never connect the cable back to itself. Apply blocks to the wheels
of the vehicle when on an incline. Duration of winching pulls should be kept as
short as possible. If the motor becomes uncomfortably hot to the touch, stop
winching immediately and let it cool down for a few minutes. Do not pull for
more than one minute at or near the rated load.
CAUTION –If the motor stalls do not maintain power to the winch. Electric
winches are designed and made for intermittent use and should not be used in
constant duty applications.
CAUTION –Never disengage the clutch when there is a load on the winch..
CAUTION –Use the hand saver hook when handling the hook for spooling or
un-spooling the wire rope.
GENERAL TIPS FOR SAFE OPERATION
The 4,500lbs and its all-derivative types are rated at 4,500lbs capacity when
spooling the first rope layer on the drum.
Overloading can damage the
winch/motor/ or wire rope.
For loads over 70% of rated line pull, we
recommend the use of the pulley block/snatch block to double the wire rope
line. This will aid in two ways: a) reduce the number or rope layers on the drum,
as well as, b) reduce the load on the wire rope by as much as 50%. When
doubling the line back to the vehicle, attach to the frame or other load bearing
part.
The vehicle engine should be kept running during operation of the winch to
minimize battery drain and maximize power and speed of the winch. If the
winch is used for a considerable amount of time with the engine off, the battery
may be drained and too weak to restart the engine.
Get to know your winch before you actually need to use it. We recommend that
you set up a few test runs to familiarize yourself with rigging techniques, the
sounds your winch makes under various loads, the way the cable spools on the
drum, etc.
5

Inspect the wire rope and equipment before each use. A frayed or damaged
rope must be replaced immediately. Use only the manufacturer’s replacement
rope with the exact specifications.
Inspect the winch installation and bolts to ensure that all bolts are tight before
each operation.
Never connect the cable back to itself. This will cause cable damage. Always
use a snatch block, sling or chain of suitable strength as shown in the
illustrations.
Store the remote control inside your vehicle in a place that it will not be
damaged.
Any winch that appears to be damaged in any way, is found to be worn, or
operates abnormally shall be removed from service.
Pull only on parts of the vehicle as specified by the vehicle manufacturer.
Only attachments and/or adapters supplied by the manufacturer shall be used.
Whenever before your winch start to working, please slightly test-run your
winch in two direction, even if the winch drum only round a few degree of angle,
ensure the winch is well-balanced, especially after you operated the clutch,
test-running winch can make winch in gear.
WINCHING TECHNIQUES A-Z
a. Take time to asses your situation and plan your pull.
b. Put on gloves to protect your hands.
c. Disengage the clutch to allow free-spooling and to save energy.
d. Attach the hand saver hook to the clevis hook.
e. Pull out the wire rope to your desired anchor point using the hand saver hook.
f. Secure the clevis hook to the anchor point: Sling, chain or snatch block. Do
attach the hook back onto the wire rope.
g. Engage the clutch.
h. Connect the remote control to the winch.
i. Start your engine to ensure power is being replenished to the battery.
not
j. Power in the wire rope guiding the wire under tension to draw up the slack in the
wire. Once the wire is under tension stand well clear. Never step over the wire rope.
6

k. Disengage the clutch to allow free-spooling and to save energy.
l. Inspect the wire rope. Make sure there are at least 5 wraps of wire rope around the
winch drum.
m. Drape a blanket or jacket over the wire rope approximately 5 to 6 feet from the
hook. Open the hood for added protection.
n. Clear the area. Make sure all spectators are back and that no one is directly in
front or behind the vehicle or anchor point.
o. Begin winching. Be sure that the wire rope is winding evenly and tightly around the
drum. The vehicle that is being winched can be slowly driven to add assistance to the
winching process. Avoid shock loads; keep the wire rope under tension.
p. The vehicle to be winched should be placed in neutral and the emergency brake
released. Only release the brake pedal when under full tension. Avoid shock loads to
the winch. This can damage the winch, rope and vehicle.
q. The winch is meant for intermittent use. Under full load with a single line rig do not
power in for more than a minute without letting the motor cool down for a few minutes
and then resume the winching operation.
r. The winching operation is complete once the vehicle is on stable ground and is able
to drive under its own power.
s. Secure the vehicle. Be sure to set the brakes and place the vehicle in park.
t. Release the tension on the wire rope. The winch is not meant to hold the vehicle for
long periods of time.
u. Disconnect the wire rope from the anchor.
v. Rewind the wire rope. Make sure that any wire already on the drum has spooled
tightly and neatly. If not, draw out the wire and re-spool from the point where the rope
is tight.
w. Keep your hands clear of the winch drum and fairlead as the wire rope is being
drawn in.
x. Secure the hook and hook strap.
y. Disconnect the remote control and store in a clean, dry place.
z. Clean and inspect connections and mounting hardware for next winching operation.

WINCH ASSEMBLY AND MOUNTING
1.
Your 4500lb 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 popular vehicles and mounting channels. If you will 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.
Start by connecting the roller fairlead (Part# P450800) to the mounting channel
using 2 each of the cap screw M8 X 20 (Part# P450024), flat washer (Part#
P450002), lock washer (Part# 450003) and securing with Nut M8 (Part#
P450023). (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.)
Assemble the winch to the mounting channel by first pulling and releasing the
clutch knob to “CLUTCH OUT” position. Pull out a few inches of cable from the
drum and feed the wire loop through the opening in the front of the mounting
channel and roller fairlead. Now, using the remaining M8 x 35 cap screws
(Part# P450004), flat washer (Part# P450002), lock washer (Part# P450003)
and nut M8 (Part# P450005) secure the winch to the mounting channel.
Connect the battery and motor leads as the drawing above. Keep in mind that
every type of winch is different each other.
CAUTION –Batteries contain gases which are flammable and explosive.
2.
3.
4.
Wear eye protection during installation and remove all jewelry. Do not lean over
battery while making connections.
Assemble the clevis hook to the cable. Take off the pin from the clevis hook,
connect the clevis hook to the cable and mount the pin back to the clevis Hook.
Always use the hand saver when free-spooling and re-spooling the wire rope.
Using the hand saver keeps your hands and fingers away from the rotating
drum.
Check for proper drum rotation. Pull and turn the clutch knob to the “CLUTCH
OUT” position. Pull out some cable from the drum, and then turn the clutch
knob to the “CLUTCH IN” position to engage the gears. Press the cable out
button on the power switch. If the drum is turning and releasing more cable
then your connections are accurate. If the drum is turning and collecting more
cable then reverse the leads on the motor. Repeat and check rotation.

WINCH 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 from 5,000lbs to 10,000lbs.
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.
