Operation - Section 30 OM3070 Page 30-12 Operating Instructions SAFE PARKING PROCEDURES The operator must continue the use of safety precau- tions when preparing for parking and engine shut- down. ENGINE SHUTDOWN PROCEDURE The following procedure must be followed at each engine shutdown. 1. Stop the truck. Reduce the engine rpm to low idle. Place the selector switch in NEUTRAL and apply the parking brake switch. If the engine shutdown with timer delay is preferred, refer to the Delayed Engine Shutdown procedure.
In the event that the equipment is being worked in consecutive shifts, any questionable truck perfor- mance the operator may have noticed must be checked by maintenance personnel before the truck is released to another operator. 2. Allow the engine to cool gradually at low idle for three to five minutes. 1. Park the truck on level ground, if possible. If parking on a grade, position the truck perpen- dicular to the grade. 3. With the truck stopped and the engine cool, turn the key switch counterclockwise to OFF for nor- mal shutdown of the engine. If the engine does not shutdown with the key switch, use the engine shutdown switch on the center console (see Operator Controls section). 2.
Apply the parking brake and install wheel chocks so that the truck cannot roll. Park each truck a safe distance from one another. 3. Haul roads are not safe parking areas. In an emergency, pick the safest spot most visible to other machines in the area. If the truck becomes disabled, mark the truck with warning flags in daylight, or flares at night. 4. With the key switch OFF and the engine stopped, wait at least 90 seconds. Ensure the pressure is relieved in the steering circuit by turning the steering wheel back and forth sev- eral times. No front wheel movement will occur when hydraulic pressure is relieved. 5.
Close and lock all windows, remove the key from the key switch, and lock the cab to prevent possible unauthorized truck operation. Dis- mount the truck properly.
