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.

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 8 (Tire Wear Troubleshooting) will help pinpoint the causes and solutions of tire wear problems.

CAUTION:

Suspension

The leaf suspension springs and associated components (Figure 29) should be visually inspected every 6,000 miles for signs of excessive wear, elongation of bolt holes, and loosening of fasteners. Replace all damaged parts (sus- pension) immediately. Torque locknut securing U-clamp to spring leaf between 45 and 50 ft.-lbs.

ALWAYS wear safety glasses

NOTE when removing or installing force fitted parts. Failure to comply may result in serious injury.
