Operating Instructions - Section 30 7/09 OM3050 Page 30-10 PASSING 4. When the truck is stopped and in the dump position, apply the wheel brake lock and move the directional control lever to NEUTRAL. 1. Do not pass another truck on a hill or blind curve. Only use areas designated for passing. 2. Before passing, ensure the road ahead is clear. If a disabled truck is blocking your lane, slow down and pass with extreme caution. LOADING Dumping 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 movement may jolt the truck violently and cause possible injury to the operator and/or damage to the hoist cylinders, frame, and/or body hinge pins. 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 out for other vehicles and personnel working in the area. 4. When pulling in under a loader or shovel, follow the spotter or shovel operator’s 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. 5.
During loading, the operator must stay in the cab with the engine running. Place the directional control lever in NEUTRAL and apply the brake lock. 6. When loaded, pull away from shovel as quickly as possible but with extreme caution. 5. Pull the lever to the rear to actuate the hoist circuit. Releasing the lever anywhere during "hoist up" will hold the body at that position. DUMPING Raising The Dump Body 6. Raise the engine rpm to accelerate the hoist speed. If dumping very large rocks or sticky material as described in the WARNING above, slowly accelerate the engine to raise the body. When the material starts to move, release the hoist lever to the HOLD position.
If the material does not continue moving and clear the body, repeat this procedure until the material has cleared the body. 1. Pull into the dump area with extreme caution. Ensure the area is clear of persons and obstructions, including overhead utility lines. Obey signals directed by the spotter, if present. 2. Avoid unstable areas. Stay a safe distance from the edge of the dump area. 7. Reduce the engine rpm as the last stage of the hoist cylinder begins to extend. Let the engine go to low idle as the last stage reaches half- extension. To prevent tipping or rolling, position the truck on a solid, level surface before dumping. As the body raises, the truck center of gravity will move. 8.
Release the hoist lever as the last stage of the hoist cylinder reaches full extension. 3. Carefully maneuver the truck into the dump position. When backing the truck into the dump position, use only the foot-operated brake pedal to stop and hold the truck. Do not rely on the wheel brake lock to stop the truck. This control is not modulated and applies the rear service brakes only . 9. After the material being dumped clears the body, lower the body to the frame.
