operator’s seat. It allows you to start or stop the spray operation. Press the switch to enable or disable the spray system. Left, Center, and Right Section Switches The left, center, and right section switches are located on the control panel (Figure 52). Toggle each switch forward to turn the corresponding section on and rearward to turn them off. When the switch is turned on, a light on the switch illuminates. These switches affect the spray system only when the master section switch is on.
Flow meter The flow meter measures the flow rate of the fluid to the boom section valves (Figure 54). Section Valves Use the boom-section valves to turn the sprayer pressure on or off to the sprayer nozzles in the left, center, and right boom sections (Figure 54). Section-Bypass Valves The boom section-bypass valves (Figure 55) redirect the fluid flow from a boom to the tank when you turn off the boom section.
Operation Note: Determine the left and right sides of the machine from the normal operating position. Note: If you need to transport the vehicle on a trailer with the sprayer installed, make sure that the booms are tied down and secure. g028857 Figure 57 Before Operation 1.

Filling the Tanks Important: Ensure that the chemicals you use are compatible for use with VitonTM (see the manufacturer's label; it should indicate if it is not compatible). Using a chemical that is not compatible with VitonTM degrades the O-rings in the sprayer, causing leaks. Filling the Freshwater Tank Important: Do not use reclaimed water (gray water) in the freshwater tank.

Before you start the engine, ensure that you are in the operating position, the transmission is in neutral, and the parking brake is engaged. You and any passengers should remain seated whenever the machine is in motion. Keep both hands on the steering wheel whenever possible. Always keep your arms and legs within the operator’s compartment.
Operating the Sprayer gradually downhill, if possible. Use care when reversing the machine. To operate the Multi Pro WM, first fill the spray tank, then apply the solution to the work area, and finally clean the tank. It is important that you complete all 3 of these steps in succession to avoid damaging the sprayer. For example, do not mix and add chemicals in the spray tank at night and then spray in the morning. This would cause the chemicals to separate and possibly damage the sprayer components.

Changing the Spray Section Position Positioning the Spray Sections Perform the following steps to move the outer spray sections to the SPRAY position: The boom-section lift switches on the sprayer control panel allows you to move the outer spray sections between transport position and spray position without leaving the operator's seat. Whenever possible, stop the machine before changing spray section positions. 1. Park the machine on a level surface. 2.
Using the Boom-Section Transport Cradle inadequate to achieve the desired application rate. To correct you application rate, slow your ground speed to achieve your application rate or select a sprayer nozzle with a higher application rate range. The sprayer is equipped with boom-section transport cradles that have a unique safety feature.
After Operation After Operation Safety • Park the machine on a level surface; engage the parking brake; shut off the engine; remove the key; and wait for all movement to stop before leaving the machine. After you finish operating the machine for the day, wash off all chemical residue from the outside of the machine; refer to Chemical Safety. Allow the engine to cool before storing the machine in any enclosure. Maintain and clean the seat belt(s) as necessary.
9. Set the master-section switch to the OFF position, shut off the sprayer pump, and shut off the engine. 10. Repeat steps 1 through 9 at least 2 more times to ensure that the spray system is fully cleaned. Important: You must always complete this procedure at least 3 times to ensure that the spray system is fully clean, preventing damage to the system. 11. Clean the suction filter and pressure filter; refer to Cleaning the Suction Filter (page 65) and Cleaning the Pressure Filter (page 65).
Cleaning the Nozzle Filter 1. Park the machine on a level surface, engage the parking brake, shut off the sprayer pump, shut off the engine, and remove the key. 2.

Assembling the Manifold Valve Operator supplied material: Clear silicone grease. Important: Use only silicone grease when assembling the valve. 1. Check the condition of the outlet fitting O-rings (section valve manifold only), end cap O-rings, back seating O-rings, and ball seat for damage or wear (Figure 123 and Figure 124). Note: Replace any damaged or worn O-rings or seats. g028240 2. Apply silicone grease to the valve stem and insert it into the valve stem seat (Figure 123 and Figure 124). 3.
Installing the Rate Control Manifold Valve 1. 4. Align a gasket between the flanges of the rate control valve manifold and the pressure filter head (Figure 126A). 5. Note: If needed, loosen the mounting hardware for the pressure filter head as needed to provide clearance. 6. 7. 8. Assemble the rate control valve manifold, gasket, and agitation-valve manifold with a flange clamp and tighten by hand (Figure 126A).
2. Assemble the agitation bypass valve, gasket, and agitation-valve manifold with a flange clamp and tighten by hand (Figure 128). 3. Align a gasket between the flanges of the rate control valve and the agitation-valve manifold (Figure 128A). Installing the Master Boom Manifold Valve 1. Align the flange of the master-boom-valve manifold, a gasket, and the flange of the master-boom bypass valve (Figure 129). g033605 Figure 128 1. Flange (rate control valve) 5.
