Periodic Preventive Maintenance
• Keep hoist free of dirt, oil, grease, water and
other substances.
• Check all mounting bolts and make sure
they are tightened to the recommended
torque values on the product data sheet.
Replace any damaged fasteners.
• Periodically check all connections to be sure
they are tight and free of corrosion.
• Check rope for visible damage every time
hoist is operated. Examples of damage are:
cuts, knots, mashed or frayed portions, and
broken strands. Replace rope immediately
if damaged. Failure to replace a damaged
rope could result in breakage.

WARN Industrial Hoists
• Regularly check brake for slippage or drift.
This is detected visually when hoist is under
load. If hoist drum continues to turn after
controls are released, brake may need to
be replaced.
• Periodically clean and grease brake
assembly. This will ensure proper
performance and extend the life of the hoist.
If hoist 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 bushes and brake
assembly require periodic replacement.
Semi-annually or after each
25 hours of operation
