WARNINGS
•Do not exceed the rated load capacity indicated in this manual.
•Intermittent use only. Allow the winch to cool between each use.
•Do not use the winch to lift a load (vertically).
•NEVER use the winch to lift or move people in any way.
•NEVER cut, weld or modify any part of the winch or the cable.
•A minimum of five turns of steel cable around the drum are required to pull and hold the
rated load. For synthetic cable, ensure a minimum of 10 turns.
•When the winch is in use, please ensure that all people present (including yourself) are
a safe distance away from the cable.
•The cable (whether steel or synthetic) may break before the motor stalls. For heavy
loads (at or near rated load capacity), use a pulley block to reduce the load on the
cable.
•Never step on a cable and never approach a loaded cable.
•Do not move the towing vehicle in order to pull the load with the winch cable. This
could cause the cable to break.
•Please ensure that the remote control and battery cables are disconnected when not in
use.
•Please avoid jolting the cable by using the controls intermittently to remove slack in the
cable. Jolts can far exceed the load capacity of the cable and the drum.
•Do not exceed the maximum rated pulling capacity indicated in this manual.
•When winding the cable, please ensure that it is wound in the correct direction and that
it winds around the drum from the bottom and not from the top. To ensure that the
cable is wound correctly, you should apply light tension to the cable while pressing the
button on the remote control to pull the cable. Move towards the winch to avoid the
cable slipping between your hands. Do not move your hands within 30 cm of the winch
when winding. Turn off the winch and repeat this process until there are only a few cm
of cable left. Disconnect the remote control and finish winding the cable by
disengaging the clutch and turning the drum by hand. Keep your hands away from the
roller fairlead and the drum when the winch is powered.
•Failure to pay attention to these warnings may result in personal injury and/or damaged
property.
•Use gloves to protect your hands when handling the cable. Never allow the cable to slip
between your hands.
•Never attach the cable to itself. When the vehicle is on a slope, apply chocks to the
wheels. When pulling a load, the winch should be run for the shortest time possible. If
the motor becomes too hot to touch, stop winching immediately and allow the motor to
cool for a few minutes. Do not run the winch for more than a minute if you are at or near
the rated load.

06EQUIPMENT INFORMATION
6.1. General information
This winch is a powerful machine which must be handled with extreme caution with attention paid
to all cautions and warnings indicated in this manual. It is important that you understand its
specifications and the basics of how it works so that you can use it safely and with complete
confidence whenever you need to.
Below, you will find a list of the winch’s components and their functions. We recommend that you
practice using the winch before finding yourself in a situation where you need to use it.
1. This winch is designed for maximum pull strength with a single layer of cable wound around
the winch drum (the first layer).
2. The motor is fed by a 12 or 24-volt battery which powers the gear mechanism that spins the
drum and winds the cable. Before use, ensure the winch is connected to the correct supply
voltage.
3. The winch drum is the cylinder around which the cable is wound. It can unwind or rewind the
cable, depending on which button is pressed on the remote control.
4. The winch may be equipped with a cable (galvanised steel aircraft cable), which is specifically
designed for a rated pulling load of 9072 kg. The cable is wound around the drum from the
bottom through the roller fairlead and has a loop at the end to allow the hook to be attached.
5. When the winch is used at an angle, the roller fairlead guides the cable onto the drum. This
minimises damage to the cable caused by abrasion on the winch support or the vehicle
bumper.
6. The gearbox converts the power of the motor into an extreme pulling force.
7. A braking action is automatically applied to the drum when the motor is stopped and the cable
is loaded. The braking action is complemented by a separate mechanical brake.
8. The clutch allows the operator to manually disengage ("DISENGAGE") the drum from the
gearbox. "ENGAGE" locks the drum to the gearbox.
9. Solenoid: Power from the vehicle battery feeds the winch motor via a sealed switch.

EN - ENGLISH – 01/2020
Translation of original instructions 7EN Reproduction is prohibited
10. The power switch cables have a double switch to turn the winch on or off. The remote control
allows you to keep a safe distance from the cable when it is loaded.
11. The wireless remote control (optional, contact us): allows you to control the winch from a
distance of up to approx. 15 metres.
12. The winch can also be supplied with a mounting plate (optional, contact us) which can be
mounted on most flat surfaces such as trailers, bumper steps, truck beds, etc. The mounting
plate also has holes for attaching the roller fairlead.
13. The winch can also be supplied with a pulley block (optional, contact us) to double the winch’s
pulling power or change the pulling direction without damaging the cable. We recommend that
you use a double line and a pulley block when pulling more than 70% of the rated pulling load.

07MOUNTING - INSTALLATION
Accessories you will need which are not included with the winch:
•Gloves for handling the cable and hook safety strap.
•Anchoring sling/chain.
•Blanket to throw over the cable to absorb the energy if the cable breaks.
1. The winch is designed with a standard bolt pattern for this class of winch. Many winch
mounting kits use this bolt pattern for common vehicles and mounting plates. If you wish to use
a mounting plate, ensure that it is mounted on a flat surface so that the motor, drum and
gearbox housing are correctly aligned. Correct alignment of the winch will ensure uniform
distribution of a rated load.
2. Begin by assembling the roller fairlead and the mounting plate using 2 screws M10 X 35, a washer,
a lock washer securing the whole with a M10 nut. Ensure that the screws are inserted through the
mounting plate from the inside and through the roller fairlead. This will ensure that there is enough
space for the winch to be placed on the plate.
3. Assemble the winch on the mounting plate by pulling and turning the clutch switch to the
"DISENGAGE" position. Pull a few centimetres of cable from the drum and pass the cable loop
through the opening at the front of the mounting plate and through the roller fairlead. You may
now attach the winch to the mounting plate using the remaining screws M10 x 35, the washer,
the lock washer and the M10 nut.
4. Installation of the control enclosure :

5. Connect the battery and the motor cables as shown in the diagram below. Bear in mind that
each type of winch is different.
CAUTION
Batteries contain inflammable and explosive gases. Always wear protective goggles during
installation and remove all jewellery beforehand. Do not lean over the battery while making
the different connections.
6. Attach the clevis hook to the cable: remove the pin from the hook, connect the hook to the
cable and replace the pin.
7. Always use the safety strap when winding or unwinding the cable. Using the nylon strap will
help you to keep your hands and fingers away from the drum when it is rotating.
8. Check that the drum rotates correctly. Pull and turn the clutch switch to the "DISENGAGE"
position. Manually pull out some of the cable and then, turn the clutch switch to the "ENGAGE"
position to lock the gearbox to the drum. Press the "OUT" button on the remote control. If the
drum turns and unwinds the cable, your connections are correct. If the drum turns and winds
up the cable, swap the motor connections. Repeat and check the drum rotation.

08COMMISSIONING - USAGE
Do not use this equipment without having first fully read and understood the user manual. Failure
to pay attention to these instructions whilst using this equipment poses a risk to your safety.
Before using the equipment, please, observe and apply the following safety instructions:
•The rated load of the winch indicates the force applied to the first layer on the drum.
Overloading can damage the winch, motor or cable. For loads greater than 70% of the rated
load, we recommend using a double-line with pulley block. This will reduce:
- the number of layers of cable on the drum,
- the load on the cable by 50%. When you double the line and attach the return line to the
vehicle, attach it to the chassis or another load-bearing part.
•The vehicle engine must be kept running while the winch is running in order to minimise the
drain on the battery and maximise the power and speed of the winch. If the winch is operated
for a considerable time with the engine off, the battery will drain and you may not be able to
restart the engine.

•Get to know your winch before you actually need to use it. We recommend that you carry out
some trial runs to practice attaching the cable, familiarise yourself with the sounds your winch
makes under different loads, observe the way the cable is wound around the drum, etc.
•Inspect the cable and equipment before each use. A frayed or damaged cable must be replaced
immediately. Only use a cable that meets the specifications recommended by the manufacturer.
•Inspect the winch’s installation and bolts to ensure that all bolts are secure before each use.
•Never attach the cable to itself or it may become damaged. Always use a pulley block, sling or
an appropriate-strength chain, as shown in the illustrations.
•Store the remote control inside your vehicle in a place where it will not get damaged.
•Any winch that looks to be damaged in any way, is found to be worn, or is not functioning
correctly should no longer be used.
•When towing a vehicle, only pull on parts specified by the vehicle manufacturer.
•Only accessories and/or adapters supplied by the manufacturer should be used.
•Before using your winch, briefly test it in both directions. Even if the drum is only at an angle of
a few degrees, ensure that the winch is well balanced, especially if you have used the clutch.
The test will engage the gearbox with the drum once again if necessary.

8.1. Winch cable techniques
Auto-recovery
NOT CORRECT CORRECT
Figure 1
Identify a suitable anchor point. When choosing an
anchor point, choose a strong, firm point such as a
tree trunk or rock.
Always use a sling as an anchor.
CAUTION
Do not attach the hook to the cable as shown
in Fig. 1, it could become damaged.
Figure 2
CAUTION
Do not winch at an acute angle. Doing so will
cause the cable to wind on one side of the drum,
which could damage the cable and the winch, as
shown in Fig. 2
Short angle pulls can be used to straighten the
vehicle. Long pulls should be done with the cable at a
90° angle to the winch/vehicle.
Figure 3
When pulling a heavy load, throw a blanket or jacket
over the cable about 1.50 m from the hook. This way,
if the cable breaks, the whiplash will be absorbed. For
extra protection, open the bonnet of your vehicle as
shown in Fig. 3.
With 1 line With2 lines
Figure 4
For pulling loads greater than 70% of the rated load,
we recommend using a pulley block to double the
line. Fig. 4.
This will reduce the load on the winch and the tension
on the cable by up to 50%, depending on the angle.
Figure 5
WARNING
Never use the winch for hoisting or lifting
or moving people. Fig. 5.

8.2. Operating the winch
Preparation before winching
1. Take some time to assess the situation and prepare your winching operation appropriately.
2. Wear gloves to protect your hands.
3. Disengage the clutch by turning the switch to the DISENGAGE position. This will allow the
cable to unwind freely and will save energy.
4. Attach the safety strap to the hook.
5. Pull the cable to the desired anchor point using the safety strap.
6. Attach the hook to the anchor point using a sling, chain or a pulley block. Do not hook the
cable onto itself.
7. Engage the gearbox by turning the switch to the ENGAGE position.
8. Connect the remote control to the winch.
9. Start the vehicle engine to ensure that the battery is charging. The vehicle engine must be
running to provide maximum power to the winch. The vehicle should be in neutral with the
handbrake applied. Chock the wheels to prevent it from moving.
10. Gradually put the cable under tension by gently guiding it. Once the cable is under tension,
keep a safe distance. Never step on the cable.
11. Check the anchor points and make sure all connections are secure.
12. Inspect the cable. Make sure there are the minimum number of turns required around the
drum.
13. Place a blanket or jacket over the cable about 1.50 m from the hook. Open the vehicle bonnet
for extra protection.
14. Make sure the area is clear. Ensure that all other people keep a safe distance away and that
no one is directly in front of or behind either the vehicle or the anchor point.
Winching operation
15. Start winching. Ensure the cable wraps evenly and tightly around the drum. The towing vehicle
may be driven slowly to assist the winching process. Avoid jolting the cable. Keep the cable
under tension.
16. If towing a vehicle, the vehicle in question must be in neutral with handbrake released. Only
release the brake pedal when maximum tension is reached. Avoid jolting the load as this could
damage the winch, the cable and the vehicle.
17. The winch is designed for intermittent use. When pulling a full load with a single line, do not
winch for more than one minute at a time. Allow the motor to cool for a few minutes, then
resume winching.
18. Winching is complete once the vehicle in question is on stable ground and can be driven under
its own power.
19. Secure the vehicle. Be sure to park the vehicle and apply the brakes.
20. Release the tension on the cable. The winch is not designed to hold the vehicle for a long time.
21. Detach the cable from the anchor point.
22. Rewind the cable. Ensure that all of the cable already wrapped around the drum has been
wound correctly. If this is not the case, pull the cable out and wind it again with the cable under

EN - ENGLISH – 01/2020
Translation of original instructions 15EN Reproduction is prohibited
tension.
23. Keep your hands away from the drum and the roller fairlead whilst winding the cable around
the drum.
24. Secure the hook and the safety strap.
25. Unplug the remote control and store it in a suitable, dry place.
26. Clean and inspect the connections and mounting equipment for the next winching.
09maintenance
9.1. Winch
1. Periodically check the tightness of the mounting bolts and electrical connections. Remove any
dirt or corrosion and ensure the winch is always kept clean.
2. Do not attempt to disassemble the gearbox. Repairs must be carried out by the manufacturer
or an approved repair centre.
3. The gearbox has been lubricated with high-temperature lithium grease and is factory-sealed.
No internal lubrication is required.
9.2. Cable
If the cable is worn or begins to show signs that it might break, it must be replaced before using the
winch.
1. Move the switch to the "DISENGAGE" position.
2. Pull out the full length of the cable. Take note of the manner in which the existing cable is
attached to the drum.
3. Remove the old cable and attach a new cable to the drum. Insert the end of the new cable and
tighten the M8 x 10 screw.
4. Ensure that the new cable is wound around the drum in the same direction as the old one. The
cable must leave the drum from underneath the drum.
5. Move the switch to the “ENGAGE” position.
6. Wind the cable around the drum. The first five turns of steel cable (first 10 for synthetic cable)
should be done carefully so that the cable is wound correctly. Next, the cable should be wound
onto the drum with a load of at least 10% of the rated pulling force.
WARNINGS
