SAFETY OPERATION MAINTENANCESETUP
Maintenance and Servicing
Procedures not specifically explained in this manual must
be performed only by a qualified technician.
TO PREVENT SERIOUS INJURY FROM TOOL FAILURE:
Do not use damaged equipment. If abnormal noise or vibration
occurs, have the problem corrected before further use.
Note: Tow vehicles often have more frequent maintenance requirements, including changes of
engine and transmission oils and filters, lubrication of components, and cooling system checks.
Check your owner’s manual for information on scheduled maintenance of your tow vehicle.
BEFORE EACH USE: Inspect the trailer and tow vehicle according to the instructions on page 4.
Tires
1. Periodic inspection and maintenance of tires
and wheels are essential to towing safety,
including spare tires. Proper tire pressure affects
vehicle handling and the safety of your tires.
You can find the correct tire pressure for your
tow vehicle on the tire information placard.
2. Underinflation reduces the load-carrying capacity
of your tow vehicle or trailer, may cause sway and
control problems, and may result in overheating,
causing blowouts or other tire failure.
3. Overinflation causes premature tire wear
and affects the handling characteristics
of the tow vehicle or trailer.
Wheel Bearings
1. EVERY 2,000 TO 3,000 MILES OF USE,
lubricate the Hub Assemblies with a heavy weight
bearing grease, following the instructions in
Hub Bearing Maintenance on page 16.
2. After each Hub Assembly is reassembled,
tighten the Castle Nut until the wheel
starts spinning with slight resistance.
Loosen the Castle Nut about 1/6 turn from this point.
3. Insert a new Cotter Pin through the
Castle Nut and the hole in the axle.
4. Bend the Cotter Pin back,
locking it and the Nut in place.
Hub Bearing Maintenance
1. WARNING! If the following procedure is
not followed, it may result in wheel locking
and tire blowout, causing an automobile
accident or road hazard. Whenever a Hub
on a new unit requires assembly (or a Hub
is disassembled for maintenance), the
following procedures MUST be followed:
a. Using a suitable solvent, thoroughly clean
the Bearings, Dust Hub Cap, and the rest
of the parts of the Hub assembly of all
grease, dirt, metal shavings, or any other
foreign object. The parts must be cleaned
even if they are new or appear clean.
b. Allow all parts to dry completely.
c. Make sure your hands are clean and bearing
packer (not supplied) is also clean.
d. Place fresh, clean bearing grease
in the bearing packer.
e. With the grease-filled bearing packer in
one hand and the Bearing in the other,
press the Bearing into the grease, forcing
the grease inside the slots in the Bearing.
Continue doing this until every slot in the
Bearing is completely full of grease.
2. As you finish assembling the Hub, be careful not to
get any dirt or debris on any part of the assembly.
3. Replace the Dust Hub Cap over each Bearing.
