WINCH
DESCRIPTION
The winch uses the electrical power from the vehicle charging system to power a motor that winds wire rope into
the winch drum by means of planetary gear reduction.
The winch assembly includes the following:
Motor:The winch motor is powered by the vehicle electrical system and features a thermal protection switch
that automatically stops the motor function in the power-in direction if the motor gets too hot.
Winch Drum:The winch drum allows the wire rope to be stored on the winch and transmits forcetothewire
rope.
Wire Rope:The wire rope allows the winch to be connected to an anchor to provide a pulling force.
Fairlead:The fairlead consists of four rollers and acts as guide for the wire rope andminimizes damage to the
rope.
Automatic Brake:The winch is equipped with an automatic brake that will stop rotation of thewinch drum if
the winch motor is stopped.
Clutch Lever:The clutch lever allows the winch drum to be disconnected from the winch motor to allow the
wire rope to be pulled from the winch by hand.
Remote Socket:The remote socket allows the remote control to be attached to the control pack to allow the
winchtofunction.
Remote Control:The remote control provides the interface between the winch operator and the winch. The
remote control provides the ability to power the winch in, out, and stop thewinch.
OPERATION
Winch:The winch uses the electrical power from the vehicle charging system to power a motor that winds wire rope
into the winch drum via planetary gear reduction. By nature, a winch is capable of generating very high forces and
should be used with care. Do not operate the winch without reading and understanding the complete winch owner’s
manual.
Low Voltage Interrupt:The winch is equipped with a device that will interrupt winch function if the vehicle charging
system voltage drops to a low level. The winch will not power-in or out for 30seconds if this device is tripped. If the
interrupt is tripped, the vehicle should be operated at high idle for a few minutes to allow the vehicle charging sys-
tem to recover before continuing to winch.
Winch Motor Thermal Protection:The winch is equipped with athermalprotectiondeviceinthemotor.Ifthe
winch is operated for an excessive duration, the device may interrupt motor function to protect the winch motor.
During this time the winch will power-out but will not power-in. Allow the winch motor to cool for a few minutes
before continuing operation of the winch. The winch will resume normal function once the motor cools.
Remote Control:Tooperatethewinch,thetoggleswitchispresseddowntopowerthewinchinand up to power
the winch out. The winch will stop if the switch is left in the neutral (center) position.
Clutch Lever:The clutch lever is used to allow free spooling of the winch drum. Rotate theclutch lever on the
winch to disengage the clutch.
WARNING
WARNING: Disconnect and isolate battery negative cable before attempting any troubleshooting or repairs.
Do not disengage the clutch if the winch is under a load or wire rope is under tension.
Do not route electrical cables across sharp edges.
Do not route electrical cables through or near moving parts.
Always wear heavy leather gloves when handling a wire rope.
Never let wire rope slip through your hands.
Always keep hands clear of wire rope, hook loop, hook and fairlead opening during installation, opera-
tion, and when spooling in or out.
Always use supplied hook strap whenever spooling wire rope in or out, during installation or operation.
Failure to follow these instructions may result in personal injury.
