(see Figure 2-10). If the hopper door is open, all hydraulic functions should become inoperative.

2. Ensure that the warning message “Pump: Hopper Door Not Closed” appears on the multiplexed
monitor screen (see Figure 3-1) and that both Pump button and Hopper Door Open indicator
on the control panel are flashing red.
3. Verify that the hydraulic system has been rendered inoperative by activating one of the control
buttons, such as the Tailgate Up button on the control panel.
