teeth, and oil the bushings as needed.

WINCH USE, OPERATION & MAINTENANCE - ELECTRIC
Keep winch free of dirt, oil, grease, water and other substances.
Check all mounting bolts and make sure they are tightened to the recommended torque values. Replace
any damaged fasteners.
Periodically check all connections to be sure they are tight and free of corrosion.
Check cable for visible damage every time the winch is operated. Examples of damage are: cuts, knots,
mashed or frayed portions, and broken strands. Replace cable immediately if damaged. Failure to replace
a damaged cable could result in breakage.
Regularly check 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.
Periodically clean and grease brake 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.
