Maintenance
Winch Use, Operation, and
Maintenance
•
Keep the 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 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.

Lower Radiator Hose Heater Use
and Maintenance (If Equipped)
The following points should be followed when operating a
unit equipped with a lower radiator hose heater.
IMPORTANT NOTE: Improper use of the lower radiator
hose heater could result in serious personal injury.
•
Verify the cooling system is full of a proper mixture
of water and engine coolant before each use.
•
Heater is designed for all-night operation; how-
ever, 2-5 hours of heating just prior to starting is
usually sufficient for proper engine starting.
•
When heater is in operation, unit must be parked
in a level position to maintain the proper orientation
of the heater.
•
Use only an undamaged extension cord, outdoors
rated, three-prong grounded 120VAC cord with a
minimum amperage rating of 10A. Connect to
properly grounded 120VAC, GFCI outlet only.
•
Before starting the engine, unplug extension cord
from power first; then unplug heater cordset from
extension cord.

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.
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.
Winch Maintenance Schedule
After First Use
Trailer Wheel Bearings
The light tower is equipped with a grease zerk fitting to
allow lubrication of the wheel bearings without the need
to disassemble the axle hub. To lubricate the axle
bearings, remove the small rubber plug on the grease
cap, attach a standard grease gun fitting to the grease
zerk fitting and pump grease into the fitting until new
grease is visible around the nozzle of the grease gun.
Use only a high quality grease made specifically for
lubrication of wheel bearings. Wipe any excess grease
from the hub with a clean cloth and replace the rubber
plug when finished. The minimum recommended
lubrication is every 12 months or 12,000 miles (19,312
km); more frequent lubrication may be required under
extremely dusty or damp operating conditions.
•
Periodically clean and grease the 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.
