Operation - Section 30 OM3043 06/06 Page 30-6 Operating Instructions 3. Check the gauges, warning lights, and instru- ments before moving the truck to ensure proper system operation and proper instrument func- tioning. Observe the braking and steering circuit hydraulic warning lights. If the warning lights come on, shut the engine off immediately and determine the cause. 1. Look to the rear before backing the truck. Watch for and obey the ground spotter's hand signals before reversing. Sound the warning horn three times. The spotter must have a clear view of the total area at the rear of the truck. 2. Operate the truck only while properly seated with the seat belt fastened.
Keep hands and feet inside the cab compartment while the truck is in operation. 4. Ensure the headlights, work lights, and taillights are in proper working order. Good visibility may prevent an accident. Check the operation of the windshield wipers. 3. Check the gauges and instruments frequently during operation for proper readings. 5. When the truck body is in the dump position, DO NOT allow anyone beneath it unless the body-up retaining pin or cable is in place. 4. Observe all regulations pertaining to the job site's traffic pattern. Be alert to any unusual traf- fic pattern. Obey the spotter's signals. 6. DO NOT allow unauthorized personnel to ride in the truck.
DO NOT allow anyone to ride on the stairs or ladder of the truck. 5. Match the truck speed to the haul road condi- tions. Slow the truck in congested areas. Keep a firm grip on the steering wheel at all times. 7. DO NOT leave the truck unattended while the engine is on. Shut the engine off, and apply the parking brake before getting out of the cab. 6. DO NOT allow the engine to idle for extended periods of time. 7. Check the parking brake periodically during the shift while the truck is stopped. Use the parking brake only for parking. DO NOT use the parking brake for loading/dumping.
MACHINE OPERATION SAFETY PRECAUTIONS After the truck engine is started and all the systems are functioning properly, the operator must follow all the local safety rules to ensure safe machine operation. DO NOT use the brake lock for parking. With the engine stopped, hydraulic pressure will bleed- down, allowing the brakes to release! If any of the red warning lights come on, or if any gauge reads in the red area during truck opera- tion, a malfunction is indicated. Stop the truck as soon as safety permits, shut the engine off, and have the problem corrected before resuming truck operation. 8. Check the brake lock performance periodically for safe loading and dumping. 9.
Proceed slowly on rough terrain to avoid deep ruts or large obstacles. Avoid traveling close to the soft edges and the edge of the fill area. 10. Truck operation requires concentrated effort by the driver. Avoid distractions of any kind while operating the truck. Operating the truck with stalled or free spinning wheel motors may cause serious damage to the wheel motors! If the truck does not begin to move within 10 seconds after depressing the throttle pedal (selector switch in a drive position), release the throttle pedal. Allow the wheels to regain trac- tion before accelerating the engine again. 11. Before driving the truck, ensure the tires are properly inflated.
If the truck has been driven with an under-inflated tire, do not park the truck inside a building until the tire has cooled to ambient temperature.
