MS30H/MS30E MIXER —TRAILER SAFETY GUIDELINES

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 maxi- mum tire life and tread wear.

Table 5 (Tire Wear Troubleshooting) will help pinpoint the causes and solutions of tire wear problems.

Suspension

The rigid type axle and associated hardware (Figure 7) should be periodically inspected for signs of excessive wear, elon- gation of bolt holes, and loosening of fasteners. Replace all damaged parts immediately.

Figure 7. Axle Support Components

ALWAYS wear safety glasses when removing or installing force fitted

NOTE parts. Failure to comply may result

in serious injury.
