Lug Nut Pattern and Warning Label
The following labels showing the proper lug nut tightening pattern and
a warning label are located on the driver side front or front sidewall on
travel trailers, and on the driver side of the pinbox on fifth wheel units.
Lug pattern label will vary according to number of wheel lugs.
Torque Wrench Usage
1.
Tools should be maintained, in good condition, and stored
appropriately.
2.
Do not use accessories or handle extensions unless specifically
allowed by the torque wrench manufacturer.
3.
Apply torque in a slow, steady manner in a downward direction
and avoid sudden "jerking" movements.
4.
When the wrench signals (by clicking, beeping, or lights) that a
specific torque has been reached, stop immediately.
"Keep your air pressure checked, while you
are traveling, at least once a week."

VEHICLE OPERATION
TIRES
Read and understand the following before taking your first trip in your
RV.
Routine maintenance on your RV is important. To ensure your tires
are operating safely, regular inspection of the tires and checking
tire pressures is absolutely mandatory.
Alignment, balance and bearing wear will affect tire wear. Make sure
to look for cracking, bulging, uneven tread wear, etc.

Tire Pressure
You must follow the manufacturer's inflation guidelines for
maximum load capacity. Under-inflation is just as dangerous as
over-inflation.
Proper inflation should be monitored closely.
Failure to do so could result in the overheating of a
tire causing a blowout. Inflation pressure should be
as recommended by the tire manufacturer or as the federal label for
the recreation vehicle indicates.
When you are using your Recreation Vehicle, check inflation pressure
weekly. Pressure should be checked when the tires are cold. During
travel, tires heat up and pressure increases. Do not bleed air from hot
tires or your tires may then be under-inflated.
Cold tire inflation pressure is defined as a tire that has not been used
for three or more hours, or has been driven less than one mile. Tire
inflation pressure of a hot tire may show an increase of as much as 6
psi over a cold tire.
