Operation - Section 3 OM3043 Page 30-6 Operating Instructions 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. HAULING 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. 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. 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. 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! 3. When backing the truck, give back-up signal (three blasts on the horn); when starting for- ward, two blasts on the horn. These signals must be given each time the truck is moved for- ward or backward. 4. Use extreme caution when approaching a haul road intersection. Maintain a safe distance from oncoming vehicles.
Do not use BRAKE LOCK or EMERGENCY BRAKE (if equipped) for parking.With engine stopped, hydraulic pressure will bleed down, allowing brakes to release! 5. Maintain a safe distance when following another vehicle. Never approach another vehi- cle from the rear, in the same lane, closer than 50 ft. (15 m). When driving on a down grade, this distance should not be less than 100 ft. (30 m). 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. 6. Do not stop or park on a haul road unless unavoidable.
If you must stop, move truck to a safe place, apply parking brake, and shut down engine before leaving cab. Block wheels securely and notify maintenance personnel for assistance. 10. Truck operation requires concentrated effort by the driver. Avoid distractions of any kind while operating the truck. 7. Before starting up or down a grade, maintain a speed that will insure safe driving and provide effective retarding under all conditions. Refer to Grade/Speed decal in operator's cab. LOADING 1. Pull into the loading area with caution. Remain at a safe distance while truck ahead is being loaded. 8.
When operating truck in darkness, or when visi- bility is poor, do not move truck unless all head- lights, clearance lights, and tail lights are on. Do not back truck if back-up horn or lights are inop- erative. Always dim headlights when meeting oncoming vehicles. 2. Do not drive over unprotected power cables. 3. When approaching or leaving a loading area, watch out for other vehicles and for personnel working in the area. 4. When pulling in under a loader or shovel, follow Spotter or Shovel Operator signals. The truck operator may speed up loading operations by observing the location and loading cycle of the truck being loaded ahead, then follow a similar pattern. 9.
If the Emergency Steering light and/or Low Brake Pressure Warning light (if equipped) illu- minate during operation, steer the truck imme- diately to a safe stopping area, away from other traffic if possible. Refer to item 6 above. 5. When being loaded, operator should stay in truck cab with engine running. Place Selector Switch in NEUTRAL and apply Wheel Brake Lock. 10. The Statex III w/Fuel Enhancement system monitors wheel motor, ambient, and static exciter temperatures. If any one of these values is outside the limits established, the Statex III controls will cause the engine to increase to 1650 RPM. (Normal engine RPM for haul road/ retarding operation is 1250 RPM.) 6.
When loaded, pull away from shovel as quickly as possible but with extreme caution.
