Please carefully read all of the safety instructions and decals in the safety section. Knowing this information could help you or bystanders avoid injury.

Check the following items each time you begin using the sprayer for the day:

• Check the tire pressure.

  Note: These tires are different than car tires; they require less pressure to minimize turf compaction and damage.

• Check all fluid levels and add the appropriate amount of specified fluids, if any are found to be low.

• Check the brake pedal operation.

• Check to see that the lights are working.

• Turn the steering wheel to the left and right to check steering response.

• Check for oil leaks, loose parts, and any other noticeable malfunctions. Make sure that the engine is off and all moving parts have stopped before checking for oil leaks, loose parts, and other malfunctions.

If any of the above items are not correct, notify your mechanic or check with your supervisor before taking the sprayer out for the day. Your supervisor may want you to check other items on a daily basis, so ask what your responsibilities are.

To provide proper performance and long sprayer life, follow these guidelines for the first 100 operating hours:

• Check the fluid and engine oil levels regularly and be alert for indications of overheating in any component of the sprayer.

• After starting a cold engine, let it warm up for about 15 seconds before accelerating.

• To optimize the brake system, burnish (break in) the brakes as follows:

  1. Load 454 L (120 US gallons) of water into the tank.

  2. Move the machine to and open-level area.

  3. Drive the machine at full speed.

  4. Apply the brakes rapidly.

     Note: Stop the machine in a straight line without locking up the tires.

  5. Wait 1 minute to allow the brakes to cool.

  6. Repeat steps 3 through 5 an 9 additional times.

• Avoid racing the engine.

• Vary the sprayer speed during operation. Avoid fast starts and quick stops.

• Refer to the for any special low-hour checks.

The following procedure can be used to adjust the actuators on the center boom to keep the left and right booms at level.

1. Extend the booms to the spray position.

2. Remove the cotter pin from the pivot pin (Figure 13).

6. Turn the eyelet rod in the actuator rod to shorten or lengthen the extended actuator to the desired position (Figure 14).

   Note: The eyelet rod must be turned in half or complete revolutions to allow the reassembly of the rod to the boom.

7. Once the desired position has been achieved, tighten the jam nut to secure the actuator and eyelet rod.

8. Raise the boom to align the pivot with the actuator rod. While holding the boom, insert the pin through both boom pivot and actuator rod (Figure 13).

9. With the pin in place, release the boom and secure the pin with the cotter previously removed.

10. Repeat this procedure for each actuator rod bearing, if necessary.

To operate the Multi Pro Sprayer, 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 lead to separation of the chemicals and to possible damage to the sprayer components.

The Multi Pro Sprayer has been specifically designed to have high durability in order to give it the long sprayer life you need. Different materials have been chosen for specific reasons at different locations on your sprayer to meet this goal. Unfortunately, there is no single material which is perfect for all foreseeable applications.

Some chemicals are more aggressive than others, and each chemical interacts differently with various materials. Some consistencies (e.g. wettable powders, charcoal) are more abrasive and lead to higher-than-normal wear rates. If a chemical is available in a formulation that would provide increased life to the sprayer, use this alternative formulation.

As always, remember to clean your sprayer thoroughly after all applications. This will do the most to ensure that your sprayer has a long and trouble-free life.

Always fill the fresh water tank with clean water before handling or mixing any chemicals.

The fresh water tank is located on the left side of the ROPS bar. It supplies a source of fresh water for you to wash chemicals off of your skin, eyes, or other surfaces in the case of accidental exposure.

To open the fresh water tank spigot, turn the lever on the spigot.

Install the Chemical Pre-Mix Kit for optimal mixing and exterior tank cleanliness.

Important: Ensure that the chemicals you will be using are compatible for use with Viton (see 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.

Important: Verify that the proper application rate has been set prior to filling the tank with chemicals.

1. Stop the sprayer on a level surface, move the range selector to the Neutral position, stop the engine, and set the parking brake.

2. Ensure that the tank drain valve is closed.

3. Determine the amount of water needed to mix the amount of chemical you need as prescribed by the chemical manufacturer.

4. Open the tank cover on the spray tank.

   Note: The tank cover is located in the center of the top of the tank. To open it, turn the front half of the cover counterclockwise and swing it open. You can remove the strainer inside for cleaning. To seal the tank, close the cover and rotate the front half clockwise.

5. Add 3/4 of the required water to the spray tank using the anti-siphon fill receptacle.

   Important: Always use fresh clean water in the spray tank. Do not pour concentrate into an empty tank.

6. Start the engine and set the pump switch to the On position.

7. Press the accelerator pedal to the floor and set the throttle lock to the On position.

8. Set the master boom switch to the Off position.

9. Turn the agitation valve to the On position.

10. Add the proper amount of chemical concentrate to the tank as directed by the chemical manufacturer.

    Important: If you are using a wettable powder without full agitation, mix the powder with a small amount of water to form a slurry before adding it to the tank.

11. Add the remaining water to the tank.

The boom lift switches on the sprayer control panel allows you to move the booms between transport position and spray position without leaving the operator's seat. It is recommended to change boom positions while the machine is stationary.

Important: To ensure that your solution remains well mixed, use the agitation feature whenever you have a solution in the tank. For agitation to work, the pump must be on and the engine must be running above an idle. If you stop the vehicle and need agitation on: set the parking brake, turn the pump On, press the accelerator pedal to floor, and switch the throttle lock to the On position.

Note: This procedure assumes that the pump is on from the Filling the Spray Tank procedure.

1. Lower the booms into position.

2. With the master boom switch in the Off position, set the 3 boom switches to the On position.

3. Drive to the location where you will be spraying.

4. Set the master boom switch to the On position to begin spraying.

   Note: The InfoCenter will show the booms with the spray on.

   Note: When the tank is nearly empty, the agitation may cause foaming in the tank. To prevent this, turn the agitation valve off. Alternatively, you can use an anti-foaming agent in the tank.

5. Use the rate switch to adjust and set a target.

6. When finished spraying, set the master boom switch to the Off position to turn off all booms, then set the pump switch to the Off position.

• Do not overlap areas that you have previously 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, place the range selector in the Neutral position and use the neutral engine speed lock to hold the engine speed up to keep the agitation running.

• You will obtain better results if the sprayer is moving when you turn the booms on.

• Watch for changes in the application rate that may indicate that your speed has changed beyond the range of the nozzles or there is a problem with the spray system.

Important: You must always empty and clean the sprayer immediately after each use. Failure to do so may cause the chemicals to dry or thicken in the lines, clogging the pump and other components.

Note: Install the Tank Clean Rinse Kit for optimal tank cleaning.

1. Stop the sprayer, set the parking brake, place the range selector in the Neutral position, and turn off the engine. The tank will drain to the left side of the machine.

2. Locate the tank drain valve on the left side of the machine (Figure 15).

   Note: The valve is behind the left fender bracket next to the fuel tank.

   

   Figure 15

   1. Tank drain

3. Remove the valve from the bracket, and let the valve rest on the ground.

4. Open the valve to drain any unused material from the tank and dispose of it according to local codes and the material manufacturer's instructions (Figure 15).

   Note: This allows any residual material in the line to drain.

5. When the tank has drained completely, close the drain valve and install the valve onto the bracket (Figure 15).

6. Rinse the inside of the tank with at least 22 L (6 US gallons) of clean fresh water and close the cover.

   Note: You can use a cleaning/neutralizing agent in the water as needed. On the final rinse, use only clean, clear water.

7. Start the engine.

8. Set the pump switch to the On position and use the application rate switch to increase the pressure to a high setting.

9. With the range selector in the Neutral position, press the accelerator pedal to the floor and toggle the throttle lock switch to the On position.

10. Ensure that the agitation valve is in the On position.

11. Set the master boom switch and boom control switches to the On position to begin spraying.

12. Allow all of the water in the tank to spray out though the nozzles.

13. Check the nozzles to ensure that they are all spraying correctly.

14. Set the master boom switch to the Off position, set the pump switch to the Off position, and stop the engine.

15. Repeat steps 6 through 14 at least 2 more times to ensure that the spray system is fully cleaned.

16. On the last cycle, run the last few gallons of water through the drain valve to clear the drain tubing.

17. Clean the strainer; refer to Cleaning the Suction Strainer.

    Important: If you used wettable powder chemicals, clean the strainer after each tank.

18. Using a garden hose, spray off the outside of the sprayer with clean water.

19. Remove the nozzles and clean them by hand.

    Note: Replace damaged or worn nozzles.

In case of an emergency, the sprayer can be towed for a short distance. However, we do not recommend this as a standard procedure.

Towing the sprayer is a 2–person job. If the machine must be moved a considerable distance, transport it on a truck or trailer; refer to Transporting the Sprayer.

1. Attach a tow line to the frame.

2. Put the range selector in the Neutral position and release the parking brake.

3. Tow the sprayer at less than 8 km/h (5 mph).

For moving the sprayer long distances, use a trailer. Secure the sprayer to the trailer. Also, make sure that the booms are tied down and secure. There is 1 metal loop on the front of the frame and 2 loops on the rear of the frame (Figure 21).
