a. General. The vehicle electrical system is used to power the winch. It is
recommended to have engine running while operating the winch so the
alternator recharges the battery. Increased engine rpms can be maintained by
use of the hand throttle. When engaging or disengaging the clutch, it may be
necessary to rotate the drum by hand to align gears.
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) Start engine (para. 2-10).
(4) Chock wheels.
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) Turn clutch lever (1) counterclockwise to FREE SPOOL.
Wear leather gloves when handling winch cable. Do not handle
cable with bare hands.
When fully extending winch cable, ensure that four 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 out cable (5) by hand to desired length. Connect to load leaving
1 ft (30.5 cm) of slack in cable (5).
d. Pulling Load.
Refer to table 1-16 (6,000 lb), or table 1-17 (Optional 9,000 lb),
Winch Data, for pulling load capacity.
(1) Remove remote control switch (3) from stowage box (4).
(2) Turn clutch lever (1) clockwise to ENGAGED.
Direct all personnel to stand clear of winch cable during winch
operation. A snapped winch cable will cause injury or death.
