9.3.1
Raising Mast
1. Disengage the locking pin on the mast
2. Slowly and evenly turn the crank handle clockwise
and raise the mast to
its full height
This action produces an audible clicking sound from inside the winch
mechanism
3. Release the handle slowly to lock
the mast in position
4. Make sure the locking pin on the mast is fully inserted and locking the mast
in position
WARNING
Keep hands and fingers clear of the drum and cable area of the
winch when operating.
Do not attempt to guide cable by hand.
CAUTION
Never continue turning the handle counter-clockwise if the cable
does not keep moving out.
This disengages the winch brake mechanism and can create an
unsafe or hazardous condition.

approx. 20
cm/8”. This action locks the mast in position.

NOTE
The winch brake prevents the handle from spinning rapidly backwards if ever
your hand slips off the winch handle while lowering the mast.
CAUTION
The winch brake is not fully locked until you hear at least two (2)
clicks of the ratchet. Only then do you release the handle.
