a. General. The vehicle power steering pump is used to power the winch.
The engine must be running while operating the winch. However if the engine
will not run, the winch cable may be payed out by moving the levers to FREE
SPOOL wheel position, then paying out cable down to the fifth layer. Then move
levers to LOCK position, keeping no less than five full wraps of cable on the winch
drum. When engaging or disengaging HIGH and LOW range, it will be necessary
to rotate the drum by hand to align gears. This may also be done by powering the
winch in and out with no load on cable 1/2 second at a time until full engagement
b. Preparation for Use.
The eye of the winch cable needs a thimble to keep wires from
shearing or breaking. Refer to unit maintenance for installation.
(1) Park vehicle directly facing object to be winched. Place transmission
shift lever in N (neutral), or P (Park) for M1123 and A2 vehicles.
(2) Apply parking brake.
(3) Chock wheels.
(4) Start engine (para. 2-10).
c. Unwinding Winch Cable.
Do not power out winch cable for more than 10 ft (3 m). Use free
spool for paying out long lengths of winch cable. Failure to free
spool long lengths of winch cable will cause damage to winch.
(1) Move clutch levers (1) and (2) to FREE.
Wear leather gloves when handling winch cable. Do not handle
cable with bare hands.
When fully extending winch cable, ensure that five wraps of
winch cable remain on drum at all times. Failure to do this may
cause injury or death to personnel.
Allow 1 ft (30.5 cm) of slack in winch cable prior to start of
winching operations. This allows time for winch motor start up for
maximum pulling power.
(2) Pull cable (3) by hand to desired length. Connect to load, leaving
1 ft (30.5 cm) of slack in cable (3).
