ENGAGING THE WINCH POWER TAKEOFF

TM 9-2320-273-10

OPERATING WINCHES AT TEMPERATURES BELOW -25F (-32C)

Avoid winching operations that cause sudden shock loads.

At extremely cold temperatures, metals become brittle

and sudden shock loads can cause equipment damage.

a. After the winch has been serviced by Organizational Maintenance and before

operating the winch, warm up the hydraulic system by engaging the PTO and

operating the tractor at fast idle for 30 minutes.

b. When you have warmed up the hydraulic system, operate the winch in no-load

condition by paying out about 100 feet of the wire rope at low speed. Then take

up the wire rope at low speed. Winch should now be ready for normal operation.

ENGAGING THE WINCH POWER TAKEOFF

The winch is not to be used for moving or lifting people.

Do not shift the transmission with the power takeoff

(PTO) engaged. The gears stop during shifting, which

could cause excessive loading of power takeoff.

Keep engine speed above 1100 rpm after engaging PTO or

damage to the clutch could result.

a. Place the transmission ratio selector in neutral (N).

b. Operate the engine at low idle and set the parking brakes.

c. Move the ratio selector to 1st speed and pull the PTO knob to engage the PTO. Then

return the ratio selector back to neutral (N).

d. At the winch control panel, increase the engine speed to the desired speed ABOVE

1100 RPM. Normal operation is 2100 rpm.
