EC-42S CONCRETE MIXER — MAINTENANCE (MIXER)
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.
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 8 (Tire Wear Troubleshooting) will help pinpoint the
causes and solutions of tire wear problems.
ALWAYS
wear safety glasses
when removing or installing force
fitted parts. Failure to comply may
result in serious injury.
