Maintenance
Manual Winch: Use, Operation,
and Maintenance
Prior to Use
•
Inspect rope or cable and replace if damaged.
•
Inspect mounting hardware for correct tightness
and torque if necessary.
•
Gears, ratchet pivot point, and shaft bushings must
be kept lubricated with a thin film of oil or grease.
Operation
Raising the Lights:
1. The cable must be securely fastened to the winch
drum.
2. Verify the cable and cable attachments are not
damaged. Contact Generac Mobile to order a
replacement cable if necessary.
3. Referring to the “Lift / Let Down” decal on the
winch, turn handle according to the specified
direction to lift. The ratchet MUST make a loud
clicking sound while winding the cable.
Lowering the Lights:
Referring to the “Lift / Let Down” decal on the winch, turn
handle according to the specified direction to lower. No
clicking will be heard because the brake system is
activated.
Maintenance
The following procedures should be performed at least
annually:
1. The gears and bushings of the winch must be kept
lubricated. Apply a thin film of grease to the gear
teeth, and oil the bushings as needed.
2. The ratchet pawl pivot point must be kept lubri-
cated with a thin oil.
NOTE: Do not get oil or grease on the brake mechanism.
Electric Winch (If Equipped):
Use, Operation, and Maintenance
•
Keep the winch free of dirt, oil, grease, water, and
other substances.
•
Check all mounting bolts and verify they are tight-
ened to the recommended torque values. Replace
any damaged fasteners.
•
Periodically inspect all connections to verify they
are tight and free of corrosion.
•
Inspect 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 inspect 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.
•
Periodically clean and grease the brake assembly.
This will ensure correct 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.
•
Inspect 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. Avoid
overheating the mechanical brake. 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.
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.
