SILICOSIS/RESPIRATORY WARNINGS
WARNING
SILICOSIS WARNINGRESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete, metaland
other materials with silica in their composition may give
off dust or mists containing crystalline silica. Silica is a
basic component of sand, quartz, brick clay, granite and
numerous other minerals and rocks. Repeated and/or
substantial inhalation of airborne crystalline silica can
cause serious or fatal respiratory diseases, including
silicosis. In addition, California and some other
authorities have listed respirable crystalline silica as a
substance known to cause cancer. When cutting such
materials, always follow the respiratory precautions
mentioned above.
WARNING
Grinding/cutting/drilling of masonry, concrete, metaland
other materials can generate dust, mists and fumes
containing chemicals known to cause serious or fatal
injury or illness, such as respiratory disease, cancer,
birth defects or other reproductive harm. If you are
unfamiliar with the risks associated with the particular
process and/or material being cut or the composition of
the tool being used, review the material safety data
sheet and/or consult your employer, the material
manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources on hazardous
materials. California and some other authorities, for
instance, have published lists of substances known to
cause cancer, reproductive toxicity, or other harmful
effects.
Control dust, mist and fumes at the source where
possible. In this regard use good work practices and
follow the recommendations of the manufacturers or
suppliers, OSHA/NIOSH, and occupational and trade
associations. Water should be used for dust
suppression when wet cutting is feasible. When the
hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for
the materials beingused.

TIRES/WHEELS/LUG NUTS
Tires and wheels are a very important and critical
components of the trailer. When specifying or replacing
the trailer wheels it is important the wheels, tires, and axle
are properly matched.
WARNING — Damaged Wheels
DO NOT attempt to repair or modify a
wheel. DO NOT install an inter-tube
to correct a leak through the rim. If
the rim is cracked, the air pressure in
LUG NUT TORQUE REQUIREMENTS
It is extremely important to apply and maintain proper wheel
mounting torque. Be sure to use only the fasteners matched
to the cone angle of the wheel. Proper procedure for
attachment of the wheels is as follows:
1.Start all wheel lug nuts by hand.
2.Torque all lug nuts in sequence. See Figure 39. DONOT torque the wheel lug nuts all the way down. Tighten
each lug nut in 3 separate passes as defined by Table
10.
the inter-tube may cause pieces of the
rim to explode (break-off) with great force and can cause
serious eye or bodily injury.
TIRES WEAR/INFLATION
Tire inflation pressure is the most important factor in tire
life. Pressure should be checked cold before operation.
DONOT bleed air from tires when they are hot. Check
inflation pressure weekly during use to insure the maximum
tire life and tread wear.
