Chemical Safety Safety Improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbol. Failure to comply with the instruction may result in personal injury or death. WARNING Chemical substances used in the spray system may be hazardous and toxic to you, bystanders, animals, plants, soils or other property.
• Chemicals and fumes in the tanks are dangerous; • never enter the tank or place your head over or in the opening. Follow all local/state/federal requirements for the spraying of chemicals. Before Operating • • Operate the machine only after reading and • • • • • • • • • • • • • understanding the contents of this manual. Never allow children to operate the sprayer. Never operate the sprayer without first reading and understanding the Operator's Manual.
• • • If the machine ever vibrates abnormally, stop over of vehicle and serious injury or death. Drive carefully. To prevent tipping or loss of control: – Use extreme caution, reduce speed and maintain a safe distance around sand traps, ditches, creeks, ramps, and any unfamiliar areas or other hazards. – Watch for holes or other hidden hazards. – Use caution when operating vehicle on a steep slope. Normally travel straight up and down slopes.
• Heavy loads affect stability. Reduce the weight of DANGER the load and your speed when operating on hills. Hydraulic fluid escaping under pressure can have sufficient force to penetrate skin and do serious damage. • Avoid stopping on hills, especially with a load. Stopping while going down a hill will take longer than stopping on level ground. If the sprayer must be stopped, avoid sudden speed changes, which may initiate tipping or rolling of the sprayer.

Operating the Sprayer the manufacturer's label; it should indicate if it is not compatible). Using a chemical that is not compatible with Viton will degrade the O-rings in the sprayer, causing leaks. 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.
Setting the Hydraulic Lift Lock Important: The booms can be damaged by transporting them in any position other than the “X” transport position using the boom transport cradle. Engage the hydraulic lift lever and lock it to provide hydraulic power for control of the boom lift. 1. Push forward the hydraulic-lift lever (Figure 36). To put the booms back into the transport cradle, lower the boom(s) to the spray position, and then raise the boom(s) back into the transport position.
Spraying Tips 3. • Do not overlap areas where you have previously Note: You can use a cleaning/neutralizing agent in the water as needed. On the final rinse, use only clean, clear water. sprayed. • Watch for plugged nozzles. Replace all worn or damaged nozzles. • Use the master boom switch to stop the spray flow before stopping the sprayer. Once stopped, use the neutral engine speed lock to hold the engine speed up to keep the agitation running.
InfoCenter Icon Descriptions Using the InfoCenter LCD Display Information icon The InfoCenter LCD display shows information about your machine, such as the operating status, various diagnostics, and other information about the machine (Figure 38). There is a splash screen and main information screen on the InfoCenter. You can switch between the splash screen and main information screen, at any time, by pressing any of the InfoCenter buttons and then selecting the appropriate directional arrow.
Using the Menus Adjust tank volume To access the InfoCenter menu system, press the menu access button while at the main screen. This will bring you to the main menu. Refer to the following tables for a summary of the options available from the menus: Home screen Inactive screen Calibration Active screen Menu Item Description Test Speed This menu sets the test speed for calibration. Flow Calibration This menu calibrates the flow meter.
Calibrating the Sprayer Flow 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. 1. Fill the spray tank with clean water. 2. Set the parking brake and turn the engine on. 3. Set the pump switch to the On position, and turn on the agitation. 4. Press down on the accelerator pedal until you reach the maximum engine speed, and toggle the throttle lock switch to the On position. 5.
Calibrating the Boom Bypass 14. Turn on the right boom and turn off the center boom. 15. 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. Adjust the center boom bypass valve until the pressure reading is at the previously adjusted level (typically 40 psi or 2.75 bar). 16. Turn all the booms off. 17. Turn the pump off. Select an open flat area to perform this procedure. 1.
10. Locating the Pump Turn the pump switch to the Off position. Shift the throttle lever to the Idle position and turn the ignition Off. The pump is located near the rear of the vehicle (Figure 40). g018934 Figure 40 1. Pump 38 2.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Before each use or daily Maintenance Procedure • Clean the suction strainer (More often when using wettable powders). Every 50 hours • Lubricate the pump. Every 100 hours • Lubricate the grease fittings. • Lubricate the boom hinges.

Lubrication Greasing the Sprayer System Service Interval: Every 50 hours Every 100 hours Lubricate all bearings and bushings after every 100 hours or once a year, whichever occurs first. Grease Type: No. 2 General-purpose, lithium-base grease 1. Wipe the grease fitting clean so that foreign matter cannot be forced into the bearing or bushing. 2. Pump grease into the bearing or bushing. 3. Wipe off excess grease. g009164 Figure 43 1. Bed support 3. Bed 2.
Greasing the Boom Hinges Spray System Maintenance Service Interval: Every 100 hours Important: If the boom hinge is washed with water, all water and debris must be cleared from the hinge assembly and fresh grease must be applied. WARNING Chemical substances used in the spray system may be hazardous and toxic to you, bystanders, animals, plants, soils or other property. Grease Type: No. 2 general-purpose, lithium-base grease. 1.
Pump Maintenance Inspecting the Pump Service Interval: Every 400 hours/Yearly (whichever comes first)—Inspect the pump diaphragms and replace if necessary (See an Authorized Toro Service Distributor). Every 400 hours/Yearly (whichever comes first)—Inspect the pump check valves and replace if necessary (See an Authorized Toro Service Distributor).
Cleaning the Suction Strainer Cleaning Cleaning the Flowmeter Service Interval: Before each use or daily Service Interval: Every 200 hours/Yearly (whichever comes first) (More often when using wettable powders). 1. Thoroughly rinse and drain the entire spraying system. 2. Remove the flowmeter from the sprayer and flush it with clean water. 3. Remove the retainer ring on the upstream side (Figure 47). 1.
Storage Note: Make sure to install the springs into the valve assembly. 1. Position the sprayer on a level surface, set the parking brake, disengage the PTO, stop the engine, and remove the ignition key. F. Secure the valve seats to the valve assembly with the 3 forks previously removed. 2.
