OM3043 06/06 Operation - Section 30 Operating Instructions Page 30-9 a. Move the hoist lever back to the HOIST posi- tion and fully raise the dump body. Continue to hold the hoist lever until the body is com- pletely raised. NOTE: If the dumped material builds up at the rear of the body and the body cannot be lowered, then perform steps c and d below: NOTE: If the body is not completely raised, it may lower very rapidly when the truck is moved forward and the material is cleared from the rear of the truck. c. Move the hoist lever back to the HOIST posi- tion to fully raise the dump body. Then release the hoist lever so it returns to the HOLD position. b.
Once the body is fully raised, release the hoist lever (it will return to the HOLD posi- tion). d. Shift the selector switch to forward, release the brake lock, and depress the override but- ton. Drive forward to clear the material. Stop, shift the selector switch to NEUTRAL, and apply the brake lock. Lower the body again. c. Shift the selector switch to FORWARD, release the brake lock, and press the over- ride button. d. Slowly drive forward to clear the material. NOTE:
Failure to hoist the body, after making an unsuccessful attempt at lowering the body, may result in the dump body suddenly lowering after the truck has pulled ahead of the material that was previously preventing the body from lowering. e. Once the material is cleared, stop the truck, place the selector switch in NEUTRAL, and apply the brake lock. f. Completely lower the body. NOTE: Failure to hoist the body, after making an unsuccessful attempt at lowering the body, may result in the dump body suddenly lowering after the truck has pulled ahead of the material that was previously preventing the body from lowering. DO NOT move t he truck with a raised dump body raised except in an emergency.
Fail- ure to lower the body before moving the truck may cause damage to the hoist cylinders, frame, and/or body hinge pins. To Lower The Dump Body (When dumping on flat ground): 9. It is very likely when dumping on flat ground that the dumped material will prevent the body from lowering. In this instance, the truck will have to be driven forward a short distance (just enough to cle ar the material) before the body can be lowered. 10. With the body returned to the frame, move the selector switch to FORWARD, release the brake lock, and exit the dump area carefully. a. Shift the selector switch to FORWARD, release the brake lock, and depress the override button.
Drive forward enough for the body to clear the material. Stop, shift the selector switch to NEUTRAL, and apply the brake lock. TOWING Prior to towing a truck, many factors must be care- fully considered. Serious personal injury and/or sig- nificant property damage may result if important safety practices, procedures, and preparation for moving heavy equipment are not observed. b. Move the hoist lever forward to the DOWN position and release. Releasing the lever places the hoist control valve in the FLOAT position, allowing the body to return to the frame. DO NOT tow the truck any faster than 8 kph (5 mph). A disabled machine may be towed after adhering to the following minimum precautions.
1. Shut the engine off. Chock wheels on disabled truck to prevent movement while attaching tow bar. 2. If the truck is equipped, install the hydraulic connections for steering and dumping between the towing and towed vehicles. Check the towed vehicle braking system.
