Operation - Section 3 OM3020.1 12/99 Page 3-6 Operating Instructions MACHINE OPERATION SAFETY PRECAUTIONS After the truck engine is started and all systems are functioning properly, the operator must follow all local safety rules to insure safe machine operation. If any of the red warning lights come “On” or if any gauge reads in the red area during truck operation, a malfunction is indicated. Stop truck as soon as safety permits, shut down engine if problem indicates and have problem corrected before resuming truck operation. Truck is equipped with “Slip/Slide” control.
If this function should become inoperative, operating truck with stalled or free spinning wheel motors may cause serious damage to wheel motors! If truck does not begin to move within 10 seconds after depressing throttle pedal (Selector Switch in a drive position), release throttle pedal and allow wheels to regain traction before accelerating engine again. 1. Always look to the rear before backing the truck. Watch for and obey ground spotter’s hand signals before making any reverse movements. Sound the warning horn (3 blasts). Spotter should have a clear view of the total area at the rear of the truck. 2. Operate the truck only while properly seated with seat belt fastened.
Keep hands and feet inside the cab compartment while truck is in operation. 3. Check gauges and instruments frequently during operation for proper readings. 4. Observe all regulations pertaining to the job site’s traffic pattern. Be alert to any unusual traffic pattern. Obey the spotter’s signals. 5. Match the truck speed to haul road conditions and slow the truck in any congested area. Keep a firm grip on steering wheel at all times. 6. Do not allow engine to run at “Idle” for extended periods of time. 7. Check parking brake periodically during shift. Use parking brake ONLY for parking. Do not use park brake for loading / dumping. Do not attempt to apply parking brake while truck is moving!
Do not use “Brake Lock” or “Emergency Brake” (if equipped) for parking. With engine stopped, hydraulic pressure will bleed down, allowing brakes to release! 8. Check brake lock performance periodically for safe loading and dump operation. 9. Proceed slowly on rough terrain to avoid deep ruts or large obstacles. Avoid traveling close to soft edges and the edge of fill area. 10. Truck operation requires concentrated effort by the driver. Avoid distractions of any kind while operating the truck. MACHINE OPERATION ON THE HAUL ROAD 1. Always stay alert! If unfamiliar with the road, drive with extreme caution. Cab doors should remain closed at all times if truck is in motion or unattended. 2.
Obey all road signs. Operate truck so it is under control at all times. Govern truck speed by the road conditions, weather and visibility. Report haul road conditions immediately. Muddy or icy roads, pot holes or other obstructions can present hazards. 3. Initial propulsion with a loaded truck should begin from a level surface whenever possible, but when there are circumstances where starting on a hill or grade cannot be avoided, use the “ STARTING ON A GRADE WITH A LOADED TRUCK ” procedure (next page). 4. When backing the truck, give backup signal (three blasts on the horn); when starting forward, two blasts on the horn.
These signals must be given each time the truck is moved forward or backward.
