OM3043 Operation - Section 3 Operating Instructions Page 30-7 11. When maximum truck speed is reached, haul trucks equipped with Statex III w/Fuel Enhance- ment (Fuel Saver) system will experience a DECREASE in engine RPM. To Raise dump body: NOTE: This is different from trucks equipped with Statex II or Statex III without Fuel Enhancement, which increase RPM upon reaching speed limit. The dumping of very large rocks (10% of payload, or greater) or sticky material (loads that do not flow freely from the body) may allow the material to move too fast and cause the body to move RAPIDLY and SUDDENLY.
This sudden move- ment may jolt the truck violently and cause pos- sible injury to the operator, and/or damage to the hoist cylinders, frame, and/or body hinge pins. If it is necessary to dump this kind of material, refer to the CAUTION in the following procedure: 12. Check tires for proper inflation periodically dur- ing 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 . PASSING 1. Do not pass another truck on a hill or blind curve! 4. Pull the lever to the rear to actuate hoist circuit. (Releasing the lever anywhere during HOIST UP will place the body in HOLD at that position.) 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. 5. Raise engine RPM to accelerate hoist speed. Refer to the CAUTION below. DUMPING 1. Pull into dump area with extreme caution. Make sure area is clear of persons and obstructions, including overhead utility lines. Obey signals directed by the spotter, if present. If dumping very large rocks or sticky material as described in WARNING above, slowly accelerate engine RPM to raise body. When the material starts to move, release hoist lever to HOLD posi- tion.
If material does not continue moving and clear body, repeat this procedure until material has cleared body. Avoid unstable areas. Stay a safe distance from edge of dump area. Position truck on a solid, level surface before dumping. As body raises, the truck Center of Gravity (CG) will move. Truck must be on level surface to pre- vent tipping / rolling! 2. Carefully maneuver truck into dump position. When backing truck into dump position, use only the foot-operated brake pedal to stop and hold truck; DO NOT rely on Wheel Brake Lock to stop truck; this control is unmodulated and applies REAR SERVICE BRAKES ONLY. 3.
When truck is stopped and in dump position, apply Wheel Brake Lock and move the Selector Switch to the NEUTRAL position. 6. Reduce engine RPM as last stage of hoist cylin- der begins to extend and let engine go to low idle as last stage reaches half-extension. 7. Release hoist lever as last stage of hoist cylin- der reaches full extension.
