Grease Fittings (Zerk) Maintenance (Electric Motor)

1.There are two grease (Figure 33) fittings at each end of the electric motor that will require lubrication. Lubricate these fittings about every 16 months.

2.Use Poleyrex EM (Exxon Mobil) or equalivant lubricant. Clean grease fitting, apply grease gun to fitting (1/2 shot). Remember too much grease or injecting grease too quickly can cause premature bearing failure. Slowly apply the recommended amount of grease, taking a miniute or so to apply.

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 properly matched.

WARNING Damaged Wheels

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 maximum tire life and tread wear.

WARNING Eyesight Hazard

ALWAYS wear safety glasses when removing or installing force fitted parts. Failure to comply may result in serious injury.

Table 9 (Tire Wear Troubleshooting) will help pinpoint the causes and solutions of tire wear problems.
