Winch Controls
The spring loaded, motor mounted, live air manual throttle control valve is
supplied as a standard feature on the winch. Optional remote throttle
controls may be available on some models. Reference the model code on
the winch nameplate and compare it to the sales brochure to determine
your configuration. The throttle controls provide operator control of the
motor speed and direction of drum rotation.
Winch Mounted Live Air Throttle (standard feature)
When viewed from the air motor, move the control throttle handle to the
right (clockwise) to pay out wire rope and to the left (counterclockwise) to
haul in wire rope. Refer to the attached label.
To ensure smooth operation of the winch avoid sudden movements of the
control valve. Sudden movement of the control valve may activate the
overload device. If this occurs reset the winch by pressing the "ON"
button of the emergency stop device and smoothly action the control
valve. Ensure the winch is not overloaded.
Emergency Stop Device
The emergency stop device is located at the air inlet of the winch on local
control models, or on the pendant of remote control models. When
activated, winch drum rotation will immediately cease.
1.
To start winch operation press the "ON" button.
2.
To operate winch, press the "Haul-in" or "Payout" control lever.
3.
In the event of an emergency all winch operation can be stopped by
pushing the emergency stop button. This will prevent air from
reaching the winch motor which will stop any movement.
4.
The "ON" button must be pushed to restart the winch after the
"Emergency Stop" button have been used.

Remote Control Pendant (optional feature)
Provides for remote winch control at distances up to 18 metres away from
the winch motor. Pilot air hoses connect the pendant to the winch motor to
provide winch operation. The pendant control throttle is a two lever
movable control station. Direction of winch drum rotation is determined
by the pendant control lever depressed.
• All new, altered or modified equipment should be inspected and
tested by personnel instructed in safety, operation and maintenance
of this equipment to ensure safe operation at rated specifications
before placing equipment in service.
• Never use a winch that inspection indicates is damaged.
Frequent and periodic inspections should be performed on equipment in
regular service. Frequent inspections are visual examinations performed
by operators or service personnel during routine winch operation. Periodic
inspections are thorough inspections performed by personnel trained in
inspection of the winch. Inspection intervals depend upon the nature of the
critical components of the equipment and the severity of usage.

Winch Brake
Manual Drum Brake (optional feature)
The manual drum brake may be applied by pushing down on the handle
and released by pulling up. If the handle is pushed down fully, it should
lock in that position and prevent drum rotation, until released by the
operator. The brake must be kept properly adjusted to hold the required
load.
Disengaging Clutch Equipped Winches
The function of the disengaging clutch is to disengage the wire rope drum
from the motor so that wire rope can be unwound from the drum by hand.
The disengaging clutch is located at the end of the drum on the side of the
winch opposite of the winch motor.
• Do not engage clutch when motor is running or drum is spinning, as
this produces a severe strain on parts.
• Do not disengage clutch when winch is loaded. Ensure clutch is fully
engaged before operating winch. Engage locking dog before leaving
load suspended.
• Do not engage locking dog while drum is spinning.
• Do not use winches equipped with a disengaging clutch for lifting
applications. If the label below is attached to the winch, do not use
winch for lifting.
Careful inspection on a regular basis will reveal potentially dangerous
conditions while still in the early stages, allowing corrective action to be
taken before the condition becomes dangerous.
Deficiencies revealed through inspection, or noted during operation, must
be reported to an appointed person. A determination must be made as to
whether a deficiency constitutes a safety hazard before resuming
operation of the winch.
Records and Reports
Some form of inspection record should be maintained for each winch,
listing all points requiring periodic inspection. A written report should be
made monthly on the condition of the critical parts of each winch. These
reports should be dated, signed by the person who performed the
inspection, and kept on file where they are readily available for review.
