Operating Instructions - Section 30 OM3044 Page 30-6 5. Maintain a safe distance when following another vehicle. Never approach another vehicle 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). Do not use “Brake Lock” or “Emergency Brake” (if equipped) for parking. 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, block wheels securely, shut down engine and notify mainte- nance personnel for assistance. 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. 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. 10. Truck operation requires concentrated effort by the driver. Avoid distractions of any kind while operating the truck. 8. When operating truck in darkness, or when visibil- ity is poor, do not move truck unless headlights are on. Do not back truck if backup horn or lights are inoperative. Always dim headlights when meeting oncoming vehicles. LOADING 1.
Pull into the loading area with caution. Remain at a safe distance while truck ahead is being loaded. 2. Do not drive over unprotected power cables. 9. If the Emergency Steering light and/or Low Brake Pressure Warning light (if equipped) illuminate during operation, steer the truck immediately to a safe stopping area, away from other traffic, if pos- sible. Refer to item 6 above. 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. 10. The Statex III system monitors wheel motor, ambient, and static exciter temperatures. If wheel motor or static exciter temperature 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.) 5. When being loaded, operator should stay in truck cab. Place Selector Switch in NEUTRAL and apply brake lock with engine running. 11. When maximum truck speed is reached, the truck will experience a DECREASE in engine RPM. 6.
When loaded, pull away from shovel as quickly as possible but with extreme caution. 12. Check tires for proper inflation periodically during shift. If truck has been run on a flat”, or under- inflated tire, it must not be parked in a building until the tire cools. 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 unat- tended. PASSING 1. Do not pass another truck on a hill or blind curve! 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. 2. Before passing, make sure the road ahead is clear. If a disabled truck is blocking your lane, slow down and pass with extreme caution. 3. Use only the areas designated for passing. 3. 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 back- ward. 4. Use extreme caution when approaching a haul road intersection. Maintain a safe distance from oncoming vehicles.
