Check brake band adjustment and brake band lining wear. Disassemble and
inspect disc brake.

Winch motor controls sticking.

Check pendant/throttle levers return to normal (neutral) positions when
released.

Disassemble, inspect and repair the pilot air control valve. Verify spool
adjustment.

Winch does not lift
load.

filter.

Throttle or pendant
lever moves but
winch does not
operate.

Motor may be damaged.

Disassemble and clean the motor and replace any worn or damaged parts.

Insufficient air supply.

Ensure the air pressure at the winch inlet is at least 90 psig (6.3 bar/630
kPa) at rated volume. Clean air line filter.

Emergency Stop Valve engaged.

Reset Emergency Stop valve.

Overload Device engaged.

Reduce load to within rated capacity of winch and reset Emergency Stop
Valve.

Air leak.

Check hose connections. Check hose lines for wear or damage. Replace
worn or damaged hoses.

makes excessive noise
during operation.

Improper lubrication.

Set lubricator to provide a minimum of 3 drops per minute.

kPa).

Leaking diaphragm.

Disassemble brake and replace diaphragm.

No release pressure at the brake port.

Verify proper operation of winch controls.
