OM3070 Operation - Section 30 Operating Instructions Page 30-9 HAULING 1. Stay alert! Drive with extreme caution. Cab doors must remain closed at all times if the truck is in motion or unattended. DO NOT use the brake lock for parking. With the engine stopped, hydraulic pressure will bleed- down, allowing the brakes to release! 2. Obey all road signs. Operate the truck in a con- trolled manner. Govern the truck speed by the road conditions, weather, and visibility. Report haul road conditions immediately. Muddy or icy roads, pot holes, or other obstructions can pres- ent hazards. 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. 3. When backing the truck, give the back-up signal three sounds of the horn. When starting for- ward, two sounds of the horn. These signals must be given each time the truck is moved for- ward or backward. 10. Truck operation requires concentrated effort by the driver. Avoid distractions of any kind while operating the truck. 4. Use extreme caution when approaching a haul road intersection. Maintain a safe distance from oncoming vehicles. 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. 5. Maintain a safe distance of 15 m (50 ft) when following another vehicle. When driving down- hill, maintain a distance of 30 m (100 ft). 6. DO NOT stop or park on a haul road unless unavoidable. If you must stop, move the truck to a safe place, apply the parking brake, and shut the engine off before leaving the cab. Chock the wheels securely, and notify maintenance per- sonnel for assistance. LOADING 1. Pull into the loading area with caution. Remain at a safe distance while the truck ahead is being loaded. 2.
DO NOT drive over unprotected power cables. 3. When approaching or leaving a loading area, watch for other vehicles and for personnel work- ing in the area. 7. Before starting up or down a grade, maintain a speed that will ensure safe driving and provide effective retarding. Refer to the grade/speed decal in the operator's cab. 4. When pulling in under a loader or shovel, follow the spotter or shovel operator signals. The truck operator may speed up loading by observing the location and loading cycle of the truck being loaded ahead. Then follow a similar pattern. 8.
When operating the truck in darkness, or when visibility is poor, DO NOT move the truck unless all the headlights, clearance lights, and tail lights are on. DO NOT back the truck if the back-up horn or lights are inoperative. Dim the headlights when meeting oncoming vehicles. 5. When the truck is being loaded, the operator must stay in the truck cab with the engine on. Place the selector switch in NEUTRAL, and apply the brake lock. 9. If the emergency steering light and/or low brake pressure warning light illuminate during opera- tion, immediately steer the truck to a safe stop- ping area, away from other traffic. 6. When loaded, drive away from the shovel quickly, but with extreme caution.
10. The Statex III w/fuel enhancement system mon- itors wheel motor, ambient, and static exciter temperatures. If any one of these values is out- side the limits established, the Statex III con- trols will cause the engine to increase to 1,650 rpm. Normal engine rpm for haul road/retarding operation is 1,250 rpm.\ NOTE: Never pull or tow a loaded truck.
