ST-45 PUMP —TOWING GUIDELINES

Towing Safety Precautions

CAUTION

■Check with your county or state safety towing regulations department before towing your concrete pump.

To reduce the possibility of an accident while transporting the pump on public roads, always make sure that the trailer and the towing vehicle are in good operating condition and both units are mechanically sound.

The following list of suggestions should be used when towing the pump:

■Make sure that the hitch and coupling of the towing vehicle are rated equal to, or greater than the trailer "gross vehicle weight rating" (GVWR).

■ALWAYS inspect the hitch and coupling for wear. NEVER tow the light tower's trailer with defective hitches, couplings, chains etc.

■CHECK the tire air pressure on both the towing vehicle and the trailer. Also check the tire tread wear on both vehicles.

■ALWAYS make sure the trailer section of the pump is equipped with a "Safety Chain".

■ALWAYS attach trailer's safety chain to frame of towing vehicle.

■ALWAYS make sure that the vehicle and trailer directional, backup, brake, and trailer lights are connected properly and are working properly.

■Remember in most cases the maximum speed unless otherwise posted for highway towing is 45 MPH, however before towing your pump, check your local state, and county vehicle towing requirements. Recommended off-road towing is not to exceed 10 MPH or less depending on type of terrain.

■Place chocked blocks underneath wheel to prevent rolling, while parked.

■Depending on soil conditions and location it may be necessary to place support blocks underneath the trailer's bumper to prevent tipping, while parked.

■Inflate tires to correct pressure, inspect tires for cuts, and excessive wear. See Table 5 (Tire Wear Troubleshooting).

■Check wheel mounting lug nuts with a torque wrench. Torque wheel lug nuts as described in the "Lug NutTorque Requirements", Table 7.

■Make sure brakes are synchronized and functioning properly.

■Check tightness of suspension hardware (nuts and bolts).

■Avoid sudden stops and starts.This can cause skidding, or jackknifing. Smooth, gradual starts and stops will improve gas milage.

■Avoid sharp turns to prevent rolling.

■Retract wheel stand when transporting.

■DO NOT transport pump with fuel in the fuel tank.

CAUTION

If the trailer coupler is deformed replace entire coupler. NEVER tow the pump with a defective trailer coupler.There exist the possibility of the trailer separating from the towing vehicle.

PumpTrailerVehicle Connection

1.Check the vehicle hitch ball, and trailer coupler for signs of wear or damage. Replace any parts that are worn or damaged before towing.

2.Use only the 2-inch ball diameter with a towing capability of 5,000 lbs. (2,268 kg) as indicated on the trailer's coupler. Use of any other ball diameter will create an extremely dangerous condition which can result in separation of the coupler and ball or ball failure.

3.Be sure the coupler is secured to the hitch ball and the lock lever is down (locked).

4.Attach safety chains as shown in Figure 36. Remember to cross the safety chains.

5.After towing for about 50 miles recheck the entire towing system for tightness.

Recommended Maintenance

1.Smear ball socket and clamp face with chassis grease. Periodically oil pivot points and were surfaces of coupler with SAE 30 W motor oil.

2.When parking or storing the concrete pump, keep the coupler off the ground so dirt and other debris will not build up in the ball socket.
