OPERATE WINCH (M916A1 AND M916A2) (Con’t).
(3)
The winch operator’s station is located on left side of the trac-
tor behind the cab. The operator stands on the platform provided and operates the
winch using the controls on top of the control panel.
Always wear heavy gloves when handling winch
cable. Never allow cable to run through hands;
frayed cables can cut you. Never operate winch with
less than four turns of cable on drum. Keep cable
coils tight and close together on drum while winch-
ing. Failure to follow this warning may result in
injury to personnel.
Hearing protection is required for operator and per-
sonnel working around winch station during opera-
tion.
DO NOT use winch for moving or lifting people. Seri-
ous injury could result.
Keep trailer air supply hoses away from wire rope to
prevent damage to hoses.
NOTE
Rated winch pull is set by limiting hydraulic system
relief valve pressure to maximum of 2500 psi, which pro-
vides 45,000 lb (20,250 kg) pull on bare drum. As winch
drum is loaded with wire rope, effective line pull is
reduced. The line per cable layer with 7/8-inch wire rope
is:
1 st layer 45,000 lb (20,250 kg)
2nd layer 39,265 lb (17,810 kg)
3rd layer 34,775 lb (15,773 kg)
4th layer 31,210 lb (14,156 kg)
5th layer 28,310 lb (12,841 kg)
