Periodically check the actuator mounting fasteners for
damage or loosening. Inspect the actuator for worn or
damaged parts. As you are towing your trailer, be aware
of any changes in braking quality. This could be an early
warning of brake or actuator malfunction and requires
immediate attention. Consult a certified brake specialist to
make necessary adjustment or repairs.
ADJUSTABLE CHANNEL
Your trailer may be equipped with an adjustable channel
(Figure 3) that allows the coupler to be raised or lowered
to a desired height. Periodically check the channel bolts for
damage or loosening.
WARNING
Failure to maintain proper fluid level in the actuator
may result in loss of braking action which could cause
severe property damage, injury or death.

WHEEL BEARINGS
Wheel bearings (Figure 38) must be inspected and
lubricated once a year or 12,000 miles to insure safe
operation of your trailer.
If trailer wheel bearings are immersed in water, they must
be replaced.
If the trailer has not been used for an extended amount
of time, have the bearings inspected and packed more
frequently, at least every six months and prior to use.
Follow the steps below to disassemble the wheel hub and
service the wheel bearings. See Figure 38.

DANGER
If trailer wheels are under water for a long period of
time, wheel bearings may fail. If this is the case, service
wheel bearings immediately.
The possibility exists of the wheels falling off causing
equipment damage and severe bodily harm even death!
