To Raise dump body: 1. 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. Raise engine RPM to increase hoist speed. 3. Reduce engine RPM as the last stage of the hoist cylinders begin to extend and then let the engine go to low idle as the last stage reaches half-exten- sion. 4. Release hoist lever as the last stage reaches full extension. 5.

Releasing the lever places hoist control valve in the “float” position allowing the body to return to frame. Refer to “OPERATING INSTRUCTIONS, DUMPING” for more complete details concerning this control. ____________________________________________________________________________________________________ ASH TRAY ENGINE SHUTDOWN SWITCH The Ash Tray (4, Figure 3-4) is used for extinguishing and depositing smoking materials.
