Locate the provided hand control/pendant switch.

The hand control plugs into a whip coming out of the bottom of
the control box.

Once the hand control is plugged in, you are now ready to
retract the mast.

Put the hand control in the “

in

” position.

Press the button that says “

run

” in order to retract the mast.

Letting off of the “run” button will stop the mast. Once the mast
is all the way down, let off of the “run” button.

Once the cable goes slack, stop immediately. Do not allow the
winch to “free spool”.

Important:

 The winch is designed for intermittent use only. 

Continuous running in excess of 3 minutes can damage the winch 
motor. Allow a 20 minute cooling off period before continuing use. 
Continuous use without a cooling off period will cause overheating 
and damage the motor.
