Operation Calibrating the Boom-Section-Bypass Valves Note: Before using the sprayer for the first time, if you change the nozzles, or as needed, calibrate the sprayer flow, speed, and boom bypass. Select an open flat area to perform this procedure. 1. Fill the spray tank halfway with clean water. 2. Lower the sprayer booms. 3. Move the range selector to the NEUTRAL position and set the parking brake. Figure 106 1. Knob (section-bypass valve ) 4.
Calibrating the Agitation-Bypass Valve Service Interval: Yearly Select an open flat area to perform this procedure. 1. Fill the spray tank with clean water. 2. Verify the agitation-control valve is open. If it has been adjusted, open it completely at this time. Figure 107 3. Set the parking brake and start the engine. 1. Boom-section-bypass adjustment knobs 4. Set the range selector to NEUTRAL. 5. Set the pump switch to the ON position. 12. Turn on the left boom and turn off the right boom. 6.
Maintenance Adjusting the Master-Boom-Bypass Valve Changing the Pressure Filter Screen Note: Adjusting the master-boom-bypass valve reduces or increases the amount of flow sent to the agitation nozzles in the tank when the master-boom switch is set to the OFF position. Service Interval: Every 400 hours—Change the pressure filter screen. 1. Fill the sprayer tank 1/2 full with clean water. Note: Optional pressure filter screens are available through your authorized Toro parts distributor. 2.
Note: Replace any damaged or worn O-rings for the plug, bowl, or both. 7. Install the new pressure-filter element into the filter head (Figure 110). Note: Ensure that the filter element is firmly seated into the filter head. 8. Install the bowl onto the filter head and tighten by hand (Figure 110). 9. Install the cap onto the bowl and tighten by hand (Figure 110).
Removing the Agitation-Manifold Valve 1.

Storage Perform the following maintenance steps for short-term or long-term storage: • For short-term storage (less than 30 days), clean the sprayer system; refer to your Operator’s Manual. • For long-term storage (longer then 30 days), clean the agitation valve and the 3 section valves; refer to Cleaning the Agitation and Section Valves (page 53).
Troubleshooting Troubleshooting the Spray System Problem A boom section does not spray. Possible Cause Corrective Action 1. The electrical connection on the boom valve is dirty or disconnected. 1. Turn the valve off manually. Disconnect the electrical connector on the valve and clean all leads, then connect it. 2. The fuse is open (blown). 2. Check the fuses and replace them as necessary. 3. Repair or replace the hose. 4. Adjust the boom-bypass valves. 3. A hose is pinched. 4.
