OM3023 10/00 Operation - Section 3 Operating Instructions Page 3-11 PASSING 1. Do not pass another truck on a hill or blind curve! To Raise dump body: 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. 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: 3. Use only the areas designated for passing. 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. Avoid unstable areas. Stay a safe distance from edge of dump area. Position truck on a solid, level surface before dumping. 4. Pull dump lever up to the "RAISE" position and release lever. 5. Raise engine RPM to accel- erate hoist speed. Refer to the CAUTION below.
When body is near the maximum angle, reduce engine RPM (reduce foot pres- sure on the accelerator pedal) to reduce shock load to the hydraulic system and hoist cylinders. As body raises, the truck Center of Gravity (CG) will move. TRUCK MUST BE ON LEVEL SUR- FACE to prevent 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. 3. When in dump position, place transmission range selector at the "Neutral" position, and apply the Park Brake lever/switch. 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, move hoist lever to "HOLD" posi- tion. If material does not continue moving and clear body, repeat this procedure until material has cleared body. 6. When the dump body rises to the set position (adjusted position of body positioner) dump lever returns to the "HOLD" position. If desired to raise the body further, move dump lever to raise position and dump will rise. If dump lever is released, lever will return to hold position. Dump body will stop in that position. 7. After material being dumped clears body, lower body to frame.
