MAINTENANCE (MIXER)
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.
TIRES WEAR/INFLATION
Tire infl ation 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 infl ation
pressure weekly during use to insure the maximum tire life
and tread wear.
Table 8 (Tire Wear Troubleshooting) will help pinpoint the
causes and solutions of tire wear problems.
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.
CAUTION
ALWAYS wear safety glasses when removing
or installing force fitted parts. Failure to
comply may result in serious injury.
