DUMPING 1. Pull into dump area with extreme caution. 2. Carefully maneuver truck into dump position. Obey signals directed by the spotter, if present. 3. When in dump position, apply Brake Lock and move Transmission Range Selector to the " N eutral" position To Raise dump body: 4. Pull the lever (depress the hoist switch release button, if equipped) to the rear to actuate hoist circuit. Releasing the lever anywhere during "hoist up" will place the body in "hold" at that position. 5. Raise engine RPM to accelerate hoist speed. 6. Reduce engine RPM as last stage of hoist cylinder begins to extend and let engine go to low idle as last stage reaches half-extension. 7.
Release hoist lever as last stage reaches full extension. 8. After material being dumped clears body, lower body to frame. To Lower Body: Move hoist lever (depress the hoist switch release button, if equipped) forward to "down" position and release. Releasing the lever places hoist control valve in the "float" position allowing the body to return to frame. NOTE: If dumped material builds up at body tailgate and body cannot be lowered, shift Transmission Range Selector to "D" (Drive), release Brake Lock, and drive forward to clear material. Stop, shift Transmission Range Selector to "N" (Neutral), apply Brake Lock and lower body.
The HAULPAK ® is not to be moved with the dump body raised except for emergency moves only. Fail- ure to lower body before moving truck may cause damage to hoist cylinders, frame and/or body hinge pins. 9. With body returned to frame, move Transmission Range Selector to "D" (Drive), release Brake Lock, and leave dump area carefully. HB6004 4/94 Operating Instructions HB6-7
