OM3040 03/13 Operating Instructions - Section 30 Page 30-13 Lowering The Dump Body 7. After the load clears the body, lower the body to the frame by moving the hoist control lever for- ward to the DOWN position. The dump body will start to move downward. SAFE PARKING The operator must continue the use of safety precau- tions when preparing for parking and engine shut- down. 8. Releasing the lever during the downstroke will return the lever to the FLOAT position. The body will then float down under its own weight. If dumped material builds up at the body tailgate and the body cannot be lowered, shift the trans- mission shift lever to DRIVE.
Release the brake lock switch, and drive forward to clear the mate- rial. Stop, and shift the transmission shift lever to NEUTRAL. Apply the brake lock switch and lower the dump body. See the note below. Any questionable truck performance the operator may have noticed must be checked by maintenance personnel before the truck is released for another shift. 1. The truck should be parked on level ground, when possible. If parking must be done on a grade, the truck should be positioned perpen- dicular to the grade. 2. The parking brake must be applied and/or chocks placed fore/aft of the wheels so that the truck cannot roll. Each truck should be parked at a reasonable distance from one another.
3. Haul roads are not safe parking areas. In an emergency, choose the safest spot most visible to other machines in the area. If the truck becomes disabled where traffic is heavy, mark the truck with warning flags in daylight, or with flares at night. DO NOT move the truck with the dump body raised except in the event of an emergency. Failure to lower the dump body before moving the truck may cause damage to the hoist cylinders, frame and body hinge pins. SHUTDOWN PROCEDURE The following sequence of shutdown procedure is important and should be followed at each shutdown. NOTE:
When traveling, always place the hoist control lever in the FLOAT position, regardless of whether or not the truck is loaded. If the transmission shift lever is moved to any position other than NEUTRAL when the hoist control is not in FLOAT, the central warning lamp will flash and the alarm buzzer will sound intermittently. 1. Stop the truck, and reduce engine rpm to low idle. Place the transmission range selector in NEUTRAL, and apply the parking brake. 2. Allow the engine to cool gradually by operating at low idle for 3 to 5 minutes. 9. With the body on the frame, move the transmis- sion shift lever to DRIVE. Release the brake lock switch, and carefully exit the dump area. 3.
Turn the keyswitch to the OFF position to stop the engine. 4. Close and lock all windows, remove the key from the key switch and lock the cab to prevent possible unauthorized truck operation. 5. Dismount the truck, properly.
