Window Control Switch To Raise Body: This switch (7, Figure 32-6) is spring-loaded to the OFF position. Pushing the front of the switch raises the right side cab window. Pushing the rear of the switch lowers the window. 1. Pull the lever to the rear to actuate hoist circuit. (Releasing the lever anywhere during HOIST 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.

Engine Shutdown Switch This switch (8, Figure 32-6) is used for engine shutdown by depressing this button and hold- ing it until engine stops. 4. Release hoist lever as the last stage reaches full extension. 5. After material being dumped clears the body, lower the body to frame. Use this switch to shutdown engine if engine does not shutdown by turning keyswitch OFF, or to shutdown engine without turning OFF 24 VDC electric circuits. Refer to “OPERATING INSTRUCTIONS, DUMPING” for more complete details concerning this control. There is also a ground level engine shutdown switch on the right front frame rail behind the ladder. To Lower Body:

Move hoist lever forward to DOWN position and re- lease. Releasing the lever places the hoist control valve in the normal FLOAT position, allowing the body to return to frame.
