Winch ASSEMBLY AND MOUNTING
1. Your CPE 2,000 lb 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 ATV’s and mounting channels. If
you cannot find a kit locally, contact CPE and we will provide you with the
name of a dealer near you.
2. Regardless of the mounting kit you use, ensure that your CPE winch 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.
3. Utilize the M8 x 30 mounting bolts, washers and nuts included.
4. Connect the battery (5’ 9”) and motor (4’ 1”) leads. Connect the red
(Positive+) to the in-facing terminal (marked +) on the motor and the black
(Negative-) to the out-facing terminal (marked -) on the motor. Then
connect the red (Positive+) lead from the power switch to the positive (+)
terminal of the vehicles 12 volt battery. Connect the black (Negative -)
lead from the power switch to the negative (-) terminal of the battery.
(Fig.1 & Fig. 2) CAUTION Batteries contain gases which are
flammable and explosive. Wear eye protection during installation and
remove all jewelry. Do not lean over battery while making connections.
5. Assemble the Clevis Hook to the cable. Pull and turn the clutch knob to
the “Off” position (Free-spooling). Pull out some cable from the drum.
Take off the pin from the Clevis Hook, connect the Clevis Hook to the
cable and mount the pin back to the Clevis Hook (Fig. 3 & Fig. 4)
6. Always use the Hand Saver when free-spooling and re-spooling the wire
rope. (Fig. 7) Using the Hand Saver will keeps your hands and fingers
away from the rotating drum.
7. Check for proper drum rotation. Pull and turn the clutch knob to the “off”
position (Free-spooling). Pull out some cable from the drum, then turn
the clutch knob to the “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.

SAFETY PRECAUTIONS
WARNING
WARNING – DO NOT EXCEED RATED CAPACITY.
WARNING – Intermittent use only.
WARNING - Do not use winch in lifting or moving or persons.
WARNING - A minimum of five wraps of cable around the drum barrel is
necessary for pulling and holding the rated load. The cable clamp is not
designed to hold the load without 5 wraps of cable around the barrel.
WARNING - Keep yourself and others a safe distance to the side of the
cable when 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 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 Do not exceed maximum pull rating. 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 re-spool correctly, and while wearing gloves,
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.
CAUTION - Use gloves to protect hands when handling the cable. Never
let the cable slide through your hands.
Apply blocks to the wheels of the vehicle when on an incline.
No modifications, alterations, or deviation to the winch are authorized by the
manufacturer and should not be made.
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 of intermittent use
and should not be used in constant duty applications.
CAUTION - Never release the free-spool clutch when there is a load on the
winch.
CAUTION - Use hand saver hook when handling the hook for spooling or
un-spooling the wire rope.
GENERAL TIPS FOR SAFE OPERATION
The C20049 is rated at 2,000 lbs. capacity when spooling the first rope
layer on the drum. Overloads can damage the winch/motor/ or wire
rope. For loads over 1,000 lbs. we recommend the use of the pulley
block/snatch block to double the wire rope line. The 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 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.
Inspect the wire rope and equipment before each use. A frayed or
damaged rope shall be replaced immediately. Use only
manufacturer’s identical 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
UNTIL REPAIRED. It is recommended that the necessary repairs be
made by a manufacturer’s authorized repair facility.
Pull only on areas of the vehicle as specified by the vehicle
manufacturer.
Only attachments and/or adapters supplied by the manufacturer shall
be used.
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
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
Fig 3.1
Fig 3.2
Fig 3.3
For pulls over 1,000lbs, 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
approximately 50%.
WARNING - Never use your winch for overhead hoisting or for
lifting people or moving people.
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 also save battery
power.
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 not 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.
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.
k. Double check your anchors and make sure all connections are
secure.
Fig 3.4
Fig 3.5
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 all well 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.
MAINTAINNENCE
1. Periodically check the tightness of mounting bolts and electrical
connections. Remove all dirt or corrosion and always keep clean.
2. Do not attempt to disassemble the gear box. Repairs should be done
by the manufacturer or an authorized repair center.
3. The gear box has been lubricated using a high temperature lithium
grease and is sealed at the factory. No internal lubrication is required.
REPLACING THE WIRE ROPE
1. If the wire rope has become worn or is beginning to show signs of
strands breaking it must be replaced before being used again. To do
this, remove the defective rope by free spooling. Remove the
M5x5mm bolt on the drum and release the rope.
2. Insert the end of the new rope and secure the M5 x 5 mm bolt tightly.
3. Engage the clutch and re-spool the new rope on the drum keeping
tension on the rope as it spools. Ensure that the rope is respooling in
the under wind position.
WARNING - Only replace the wire rope with the identical replacement part
recommended by the manufacturer.
