Maintenance
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.
Maintenance Activity
Inspect fasteners
Inspect electrical connections
Inspect condition of cables
Clean and grease brake assembly
Inspect motor brushes
Inspect winch and control
Trailer Wheel Bearings
The trailer axles are equipped with a Zerk grease fitting
to allow lubrication of the wheel bearings without the
need to disassemble the axle hub. Use only a high
quality grease made specifically for lubrication of wheel
bearings, such as Valvoline
Proceed as follows to lubricate the wheel bearings:
1. See
Figure
4-2. Remove the small rubber plug (A)
from the metal end cap (B).

2. Attach a standard grease gun fitting to the Zerk
grease fitting (C).
3. Pump grease into the Zerk fitting until fresh grease
is visible around the nozzle of the grease gun.
4. Wipe any excess grease from the axle hub with a
clean cloth and install the rubber plug.

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.
Before Each
Use
The minimum recommended lubrication is every 12
months or 12,000 mi (19,312 km). More frequent
lubrication may be required under extremely dusty or
damp operating conditions.
Every six months, or depending on usage, inspect for
play in each bearing by jacking up the trailer, then trying
to rock the wheel. If further assistance is required, con-
tact Generac Mobile Products Technical Service at 1-
800-926-9768.
Jack Maintenance
Inspect each jack foot before each use for damage and
remove any mud or debris. The jacks must be clean and
in good operating condition to properly support the unit.
