Trailer Safety Guidelines - MULTIQUIP MG30T2D Operation Manual

Tires/Wheels/Lug Nuts
Tires and wheels are a very important and critical compo-
nents of the trailer. When specifying or replacing the trailer
wheels it is important the wheels, tires, and axle are prop-
erly matched.
CAUTION :
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 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. DO
NOT bleed air from tires when they are hot! . Check inflation
pressure weekly during use to insure the maximum tire life
and tread wear.
Table 9 (Tire Wear Troubleshooting) will help pinpoint the
causes and solutions of tire wear problems.
CAUTION :
ALWAYS wear safety glasses when
NOTE
removing or installing force fitted
parts. Failure to comply may result
in serious injury.

and loosening of fasteners. Replace all damaged parts im-
mediately.
