Winching Principles
You need a winch to be powerful enough to pull your vehicle while overcoming the added resistance caused by obstacles, moving
water, mud, snow, sand or inclines.
As a general guide you need a winch with a maximum line pull at least 1.5 times greater than the gross vehicle weight. There are three
and are for reference only.
1. Gross Vehicle Weight (Wt): Contains a vehicle weight and the weight of the supplies and equipments carried.
2. Surface Drag (S): The characteristics of the terrain or surface to be traversed.

3. Gradient resistance: The incline of grade or slope on which the vehicle is being moved.
A gradient of 10% is a rise of one metre in ten metres.

Rolling Pull Effect required=(Wt X S) + (Wt X G)
For example, if a vehicle weighing 2994 Kgs is winched by 100% on an off road surface,
the above formula would be used as follows:
Wt: 2994 Kgs (gross vehicle weight)
G: 0.71 (gradient value of 100%)
(Wt X S)+ (Wt X G)
= 1557 Kgs + 2126 Kgs
= 3683 Kgs of effect required to recover the vehicle

Remote Hand Control Operation
• Before commencing any operation with the winch using the remote hand control
ensure that the isolator switch on the side of the control box is in the OFF position.
• Plug the control cable (with the remote hand controller attached) into the socket on
the control box and turn slightly anti-clockwise to lock into position.
• Turn the isolator switch to the ON position.
Note:
It is recommended that for the initial set-up of the winch (prior to applying any load)
that the winch be operated in the WIRED mode.
• Once the winch has been set-up then the remote hand control can be operated either
in the WIRED OR WIRELESS mode.
• To use the remote hand controller in the WIRELESS mode unplug the remote hand
controller from the control cable.
• If at any stage during operation the remote hand controller fails to operate the winch,
reset the control box by turning the isolator switch off then back on.
• The hand control is not waterproof and care must be taken in its usage.
In the event of damage or breakage, replacement hand controls are available to be
purchased through the 4x4 Tough customer service helpline.
