With assistance, place the Coupler (A14) over the vehicle’s hitch ball and pull back
on the Trigger and push down on the Handle until the Trigger locks in the slot. Pull
up and down on the Coupler to make sure the hitch ball is fitting snugly in the Cou-
pler. There should be no play between the hitch ball and Coupler.
iMPorTanT - If there is play, tighten the Adjustment Nut until no play is present:
After unlocking the Handle, the Nut retaining plate (holding the adjusting nut in
place) needs to be pressed back while the Nut is tightened. After Nut is tight-
ened, the retaining plate needs to fit in place against the flats of the nut to
prevent it from moving. This adjustment should be done by 2 people. If the
Adjustment Nut is too tight, the Handle will not lock.
After the Adjustment Nut is properly adjusted, pull back on the Trigger and push
down on the Handle until the Trigger locks in the slot. Pull up on Handle firmly to
make sure the Trigger is locked in place and the Handle cannot move. replace the
safety Pin and “r” Pin. (see figure f.)

system. noTe: Make sure to consult the operator’s manual of the towing ve-
hicle for proper connection instructions.

When towing the Trailer over long distances stop and check the tightness of all
connections and Tail Lights (A11) at least every 100 miles. Carry extra bulbs and
fuses if towing the Trailer at night over long distances.
Carry emergency flares and fire extinguisher, if required for operation in your state.

• speed rating- The speed rating denotes the speed at which a tire is designed to be driven for ex-
tended periods of time. This does not indicate that the
vehicle or rims can safely reach or maintain that speed.
These ratings are listed to the right. (The markings on
the example tire diagram show M. The markings on your
tire may differ.) Note: You may not find this information
on all tires because it is not required by law.

• Tire Ply composition and Materials used- The num-
ber of plies indicates the number of layers of rubber-
coated fabric in the tire. In general, the greater the number of plies, the more weight a tire can support.
Tire manufacturers also must indicate the materials in the tire, which include steel, nylon, polyester,
and others.
• Maximum Permissible inflation Pressure- This number is the greatest amount of air pressure that
should ever be put in the tire under normal driving conditions.

Tire care
checking Tire Pressure
note: Underinflated tires can decrease handling, stopping performance, traction, tire life,
and load-carrying capability, in addition to causing other negative and hazardous
effects, including tire failure. Overinflated tires are at greater risk of an impact break,
where the tread and casing break when striking a hard edge, often opening a huge
gash across the tread. Incorrect inflation pressure also increases tires wear rate.
Therefore, it is important to keep tires inflated properly.
Check all tires’ pressure at least monthly, due to the following factors:
• Most tires naturally lose air gradually.
• Tires can suddenly lose air if the tire strikes a pothole, curb, or other object.
• It is usually not possible to determine underinflation of radial tires by visual in-
spection.
This vehicle has 60 PSI recommended cold tire inflation pressure. The term “cold”
in this manual does not refer to the temperature outside, but it refers to the fact that a tire
that has not been driven for a period is cooler (and therefore has lower pressure) than a
tire that has been driven on. Tires heat up while being driven on. To check (or fill to) a
tire’s cold inflation, the tire must have not been driven for more than a mile or two for at
least three hours. If you check a tires pressure when it is not “cold”, the pressure will ap-
pear higher than the actual cold tire inflation.
steps for Maintaining Proper Tire Pressure
1.
Locate the recommended tire pressure on the vehicle’s tire information placard,
certification label, or in the owner’s manual. This trailer has 60 PSI recommended
cold tire inflation pressure.
2.
3.
Measure and record the tire pressure of all tires.
If the tire pressure is too high in any of the tires and the tires have not been driven
for at least three hours, slowly release air by gently pressing on the tire valve stem
with the edge of your tire gauge until you get to the correct pressure. If the vehicle
have been driven within the past three hours and the tire pressure is too high on any
tires, then recheck the pressure once the tires have been allowed to sit motionless
for at least three hours.
4.
5.
If the tire pressure is too low, note the difference between the measured tire pres-
sure and the correct tire pressure. These “missing” pounds of pressure are what
you will need to add.
At a service station, add the missing pounds of air pressure to each tire that is
underinflated.

7.
Check all the tires to make sure they have the same air pressure.
If the tires’pressure was not measured“cold”, then the pressure should be rechecked
with the tires cold as soon as possible.
Tire size
To maintain safety, only purchase new tires of the same size as the original tires.
Look at the Tire and Loading Information Placard, the Specifications Chart in this manual,
or the sidewall of the tire being replaced. If you have any doubt about selecting the correct
size, consult a tire dealer.
Tire Tread
The tire tread provides traction that prevents your vehicle from slipping, especially
if the road is wet or icy. Tires are unsafe and should be replaced when the tread is worn
down to 1/16”. Measure tread depth using a tread depth indicator (not included).
Tire rotation
Every 5,000 miles the left and right tires should be switched. This will cause the
tires to wear more evenly and last longer.
Tire Balance and alignment
The tires need to be balanced to prevent vibration when driving. This involves at-
taching small weights to the rim to offset small differences in rim and tire weight. The tires
also need to be aligned properly. Alignment is the orientation of the tires to the road surface
and their being parallel. This helps the tires to wear evenly, and provide better traction.
Both tire balance and alignment require specialized equipment that is not provided with
this vehicle.
Tire repair
To properly repair a punctured tire, the hole needs to be properly plugged and
patched from the inside of the tire. Tread punctures can be repaired if they are not too
large. Sidewall punctures should not be repaired, the tire needs to be replaced if the
sidewall is damaged. Tires should be removed from the rim to be inspected before being
plugged and patched. A qualified mechanic should remove the tire from the rim, perform
the repair, and remount the tire.

VeHicle load liMiT
steps for determining correct load limit
1.
Locate the statement “The weight of cargo should never exceed XXX pounds” on
your vehicle’s placard.
2.
3.
That figure equals the available amount of cargo and luggage load capacity.
Determine the combined weight of luggage and cargo being loaded on the vehicle.
That weight may not safely exceed the available cargo and luggage load capacity.
4.
If the trailer’s load exceeds the cargo and luggage load capacity, then the trailer
be unsafe resulting in hazardous effects, such as: Trailer’s tires will not be able to
maintain traction properly, and stopping distance will be increased significantly.
insPecTion, MainTenance, and cleaning
1.
Before eacH use, inspect the general condition of the Trailer. Check for loose
Bolts and Nuts, misalignment or binding of moving parts, cracked, bent, or broken
parts, excessively worn Safety Chain , damaged Tail Lights/Side Running Lights/
Wiring Harness, loose Lug Nuts, loose Hitch connection, and any other condition
that may affect its safe operation. If abnormal noise or vibration occurs, have the
problem corrected before further use. do not use damaged equipment.
2.
3.
4.
Before eacH use, check the Tires according to the instructions on the previous
pages.
Before eVery use and aT 500 Mile inTerVals during eVery TriP,
check and tighten the Tire Lug Nuts. Torque from 85 to 90 ft-lb.
eVery 2,000To 3,000 Miles of use, lubricate the Hub Assemblies with a heavy
weight bearing grease. follow the Bearing Packing instructions as explained
on page 5. 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. Insert a new Cotter Pin through the Castle Nut and the hole in
the axle. Bend the Pin back, locking it and the Nut in place.
5.
To clean, use only water and a mild detergent.
