Safety instructions specific to this product

WARNING:

•  Do not use the winch for lifting loads.  The winch must never be used for lifting or 

moving people.

•  Do not use the winch cable for towing vehicles, this can overload the cable and 

the winch’s gear box.

•  Do not exceed the winch’s rated load.
•  Do not use the winch under heavy load for a long time. It is intended for intermittent 

use only and must not be under constant load. If the motor becomes very hot, 
stop the winch and let it cool for a few minutes. Never operate the winch for 
longer than 1 minute at a time on maximum or near-maximum load.

•  Make sure that there are always 5 turns of winch cable left on the drum.
•  Avoid winching at extreme angles as this can result in the cable spooling up on just 

one side of the drum. This can lead to the cable tangling, resulting in damage to 
both the cable and winch.

•  Make sure that the voltage is not less than 12 V to get the maximum pulling power. 

The winch has maximum pulling force when one layer of cable is wound on 
the drum. The greater the number of layers wound round the drum, the lesser  
the pulling force.

•  Never wind the winch cable directly round the object to be winched, it could 

damage the cable. Use some kind of strap/sling.

•  Attach the winch securely to a vehicle or fixed object before operating it.  

The anchor point must be strong enough to bear the winch’s maximum load.

•  Winch slowly at first, until the cable is taut. Stop and check that all the joints are 

secure. Make sure that the hook is securely connected.

•  It is a good idea to lay a heavy blanket or jacket over the cable near the hook when 

winching heavy loads. The weight of the blanket will dampen any recoil in the cable 
and prevent it whipping around if it should break.
