Winch Use, Operation and
Maintenance—Electric
•
Keep the winch free of dirt, oil, grease, water and
other substances.
•
Check all mounting bolts and verify they are
tightened to the recommended torque values.
Replace any damaged fasteners.
•
Periodically check all connections to verify they
are tight and free of corrosion.
•
Check the cable for visible damage every time
the winch is operated. Examples of damage are:
cuts, knots, crushed or frayed portions, and
broken strands. Replace cable immediately if
damaged. Failure to replace a damaged cable
could result in breakage.
•
Regularly check the brake for slippage or drift.
This is detected visually when winch is under
load. If winch drum continues to turn after
controls are released, the brake may need to be
replaced.

assembly. This will ensure proper performance
and extend the life of the winch. If winch seems
to labor or get excessively hot during the
lowering of loads, the brake will need to be
serviced or replaced.
•
Check motor brushes periodically and replace
when necessary.
NOTE: Only the motor brushes and brake assembly
require periodic replacement.

Winch Mechanical Brake

The mechanical brake generates heat when loads are
lowered and the wire cable is powered out. Care must be
taken to avoid overheating the mechanical brake.
Whine or chatter associated with a new mechanical
brake is normal and typically disappears with use.
Overheating the mechanical brake may result in
permanent damage to, or failure of, the brake. Replace
any damaged brake components before resuming use of
the winch.
