Maintenance
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 16.
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.
Lubricate Wheel Bearings
1.
EVEry 2,000 tO 3,000 MiLES OF USE,
lubricate zerk fittings on back of Hub Assemblies
with a heavy-weight bearing grease.
WarninG! Whenever a hub is disassembled
(if a hub on a new unit requires assembly
or a hub is disassembled for maintenance),
the following procedure MUSt be obeyed.
Failure to read and obey all of the following
instructions completely will void the warranty
and can result in damage to the trailer,
property damage, or serious injury.
2.
EVEry 20,000 MiLES OF USE,
clean and repack bearings:
a. Using a suitable solvent, thoroughly clean
bearings and the rest of the parts in Hub
Assembly of all grease, dirt, metal shavings,
or any other foreign object.
parts must be
cleaned even if they are new or
appear
clean.
b. Allow all pieces to dry completely.
c. Make sure that your hands are thoroughly
clean and bearing packer (not included)
is also thoroughly clean.
d. Place fresh, clean bearing grease in the packer.
e. With the grease-filled bearing packer in one
hand and bearing in the other, press bearing
into grease, forcing grease inside slots in
bearing. Continue doing this until every slot
in bearing is completely full of grease.
f. Reassemble Hub Assemblies.
g. Thread Castle Nut onto Axle until tire
starts spinning with slight resistance,
then back off slightly and line up gaps
in Castle Nut with holes in Axle.
h. Insert a new Cotter Pin through
Castle Nut and Axle. Bend pins in
opposite directions to secure tire.
i. Replace Dust Caps, tapping with
rubber mallet to seat them.
Hitch
Check nuts, bolts, and other fasteners to ensure that hitch remains secured to tow
vehicle and coupler remains secured to trailer. The connection point may require
periodic lubrication to permit free movement of coupler to hitch ball.
Wiring
1. Make sure connector-plug prongs and receptacles,
light bulb sockets, wire splices, and ground
connections are clean and shielded from moisture.
Lightly coat all electrical terminal connections with
nonconducting (dielectric), light waterproof grease.
2. Clean prongs with very fine sandpaper, being
careful not to damage the contact area.
3. Turn lights off, then clean surface deposits
in connector holes. Lubricate lightly with
dielectric, light waterproof grease.
