OPERATION GUIDELINES
OPERATING THE WINCH
The following instructions outline the proper method of hydraulic winch operation to give safe efficient
trouble-free service.
Winch line speed should be controlled by metering the control valve with the winch control lever. Move the
winch control lever in the desired direction using a slow smooth movement of the control lever. Abrupt
lowering or raising of loads will cause shock loads and sudden changes in truck balance. When lifting heavy
loads, use slow winch line speeds.
FEATHERING THE WINCH CONTROL LEVER
Increased engine speeds may be used for paying out or taking up the unloaded winch line or extremely light
loads.
Continuous operation of the winch under high speeds and/or heavy loads may cause overheating of the
winch gearbox or brake.
The winch is equipped with a brake on “WINCH DOWN”. When lowering loads and stopping the winch line
movement, if a continued creeping down of the winch line is observed the brake may need repair or
adjustment.
BOOM TIP WINCH EXTENSION SHAFT (OPTION)
When using the optional wire take-up reel, the wire should be spooled on the take-up reel in the same
direction as the winch line is wound on the winch drum. Operate the winch control lever in the “WINCH UP”
position.
