Product Overview 20 Controls Completing the Installation of the Arag to KZ Valve Conversion Kit Agitation Switch The agitation switch is located on the center console to the right of the seat; refer to the Operator’s Manual for your machine. Toggle this switch forward to turn on the agitation in the tank or rearward to stop the agitation. When the switch is turned on, a light on the switch illuminates. To operate the agitation function, run the sprayer-system pump and run the engine above low idle.
Operation Setting the Boom-Section-Bypass Valves Manual Mode Only Important: When operating in Auto mode, the boom-sections-bypass shutoff valve must be closed. Before using the sprayer for the first time, if you change the nozzles, or as needed, calibrate the sprayer flow, speed, and set the boom-section bypass (if operating in Manual mode); refer to the calibration procedure in the Operator’s Manual.
11. Adjust the right boom-bypass knob (Figure 129) until the pressure is at the previous level. 7. Turn the master boom switch to the OFF position. 12. Turn on the right boom and turn off the center boom. 8. Use the application-rate switch to adjust the sprayer-system pressure to 689 kPa (100 psi). 13. Adjust the center boom-bypass knob (Figure 129) until the pressure is at the previous level. 9. Turn the agitation switch to the OFF position and read the pressure gauge. 14. Turn all the booms off.
Maintenance Note: Allow the bowl to drain completely. 4. Rotate the bowl counterclockwise and remove it from its filter head (Figure 132). Changing the Pressure Filter Screen 5. Remove the old pressure-filter element (Figure 132). Note: Discard the old filter. Service Interval: Every 400 hours—Change the pressure filter screen. 6. Check the O-ring for the drain cap (located at the threaded fitting of the bowl) and the O-ring for the bowl for damage and wear (Figure 132).
Note: Squeeze the 2 legs of the retainer together while pushing it down. Note: Retain the actuator and retainer for installation in Installing the Valve Actuator (page 62).
