Performing Pre-Starting Checks

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

  • Check the air pressure in the tires.

    Note: The tires of this machine are different than car tires; they require less air 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.

  • With the engine shut off, check for oil leaks, loose parts, and any other noticeable 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 daily, so ask what inspections you are responsible to perform.

Preparing the Sprayer

Filling the Spray Tank

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

Important: Whenever possible, do not use reclaimed water (gray water) in the spray tank.

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.

Important: After filling the tank for the first time, check the tank straps for any play. Tighten them as necessary.

  1. Purge the spray system of spray-system conditioner by running the sections.

  2. Park the machine on a level surface, move the range selector to the neutral position, engage the parking brake, shut off the engine, and remove the key.

  3. Ensure that the tank drain valve is closed.

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

  5. Open the tank cover on the spray tank.

    Note: The tank lid is located at 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.

  6. 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.

    g239037

    Figure 68

  7. Start the engine, engage the PTO, and set the hand throttle if equipped.

  8. Turn the agitation switch ON position.

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

    Important: If you are using a wettable powder, mix the powder with a small amount of water to form a slurry before adding it to the tank

  10. Add the remaining water to the tank.

    Note: For better agitation, decrease the application rate setting.

    During Operation

    During Operation Safety

    General Safety

    • The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage.

    • Wear appropriate clothing, including eye protection; long pants; substantial, slip-resistant footwear; and hearing protection. Tie back long hair and do not wear loose clothing or loose jewelry.

    • Wear appropriate personal protective equipment as directed in Chemical Safety.

    • Use your full attention while operating the machine. Do not engage in any activity that causes distractions; otherwise, injury or property damage may occur.

    • Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.

    • Do not carry more than 1 passenger on the machine; the passenger should sit in the designated seating position only.

    • Operate the machine only in good visibility. Avoid holes or hidden hazards.

    • Before you start the engine, ensure that you are in the operating position, the transmission is in the NEUTRAL position.

    • Remain seated whenever the machine is in motion. Keep both hands on the steering wheel whenever possible, and always keep your arms and legs within the operator’s compartment.

    • Use care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.

    • Before backing up, look rearward and ensure that no one is behind you. Back up slowly.

    • Never spray while people, especially children, or pets are nearby.

    • Do not operate the machine near drop-offs, ditches, or embankments. The machine could suddenly roll over if a wheel goes over the edge or if the edge gives way.

    • Reduce the speed when operating on rough terrain, uneven ground, and near curbs, holes, and other sudden changes in terrain. Loads may shift, causing the machine to become unstable.

    • Stop the machine, shut off the engine, remove the key, engage the parking brake, and inspect for damage after striking an object or if there is an abnormal vibration in the machine. Make all necessary repairs before resuming operation.

    • Slow down and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.

    • Use extra caution when operating the machine on wet surfaces, in adverse weather conditions, at higher speeds, or with a full load. Stopping time and distance increase in these conditions.

    • Do not touch the engine or muffler while the engine is running or soon after it has shut off. These areas may be hot enough to cause burns.

    • Before you leave the operator’s position, do the following:

      • Park the machine on a level surface.

      • Shift the transmission into the NEUTRAL position.

      • Shut off the spray pump.

      • Engage the parking brake.

      • Shut off the engine and remove the key (if equipped).

      • Wait for all movement to stop.

    • Never run an engine in an area where exhaust gasses are enclosed.

    • Do not operate the machine when there is the risk of lightning.

    • Use accessories and attachments approved by Toro only.

    Operating the Sprayer

    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.

    Important: The tank markings are for reference only and cannot be considered accurate for calibration.

    Caution

    Chemicals are hazardous and can cause personal injury.

    • Read the directions on the chemical labels before handling the chemicals, and follow all manufacturer recommendations and precautions.

    • Keep chemicals away from your skin. Should contact occur, wash the affected area thoroughly with soap and clean water.

    • Wear goggles and any other protective equipment recommended by the chemical manufacturer.

    The Multi Pro WM has been specifically designed to have high durability 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 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 machine and spray system thoroughly after all applications. This ensures that your sprayer has a long and trouble-free life.

    Spraying

    Using the Sprayer

    Important: To ensure that your solution remains well mixed, use the agitation feature whenever you have solution in the tank. For agitation to work, you must engage the PTO and the engine must be running above an idle. If you stop the vehicle and need the agitation on, place the shift lever in the NEUTRAL position, engage the parking brake, engage the PTO, engage the clutch, and set the hand throttle, if equipped.

    Note: This procedure assumes that the PTO is engaged (HD-series models with a manual transmission) and the section valve calibration is complete.

    1. Lower the booms into position.

    2. Set the master-section switch to the OFF position.

    3. Set the individual section switches, as needed, to the ON positions.

    4. Drive to the location where you plan to spray.

    5. Navigate to the Application Rate screen on the InfoCenter and set the desired rate by performing the following steps:

      1. Ensure that the switch for the pump is in the ON position.

      2. For HD-series models with a manual transmission, select the desired gear range.

      3. Begin driving at your target ground speed.

      4. Verify that the monitor displays the correct application rate. If needed, adjust the application-rate switch until the monitor displays the desired application rate.

      5. Return to the location where you are spraying.

    6. Set the master-section switch to the ON position and begin spraying.

      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.

    7. When finished spraying, set the master-section switch to the OFF position to turn off all spay sections, and disengage the PTO lever (HD-series models with a manual transmission).

    Turf Care Precautions while Operating in Stationary Modes

    Important: Under some conditions, heat from the engine, radiator, and muffler can potentially damage grass when operating the sprayer in a stationary mode. Stationary modes include tank agitation, hand spraying with a spray gun, or using a walking boom.

    Use the following precautions:

    • Avoid stationary spraying when conditions are extremely hot and/or dry, as turf can be more stressed during these periods.

    • Avoid parking on the turf while stationary spraying. Park on a cart path whenever possible.

    • Minimize the amount of time that you leave the machine running over any particular area of turf. The extent of damage to the grass depends on both time and temperature.

    • Set the engine speed as low as possible to achieve the desired pressure and flow. This minimizes the heat generated and the air velocity from the cooling fan.

    • Allow the heat to escape upward from the engine compartment by raising the seat assemblies during stationary operation rather than being forced out under the vehicle.

    Positioning the Spray Sections

    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.

    Setting the Hydraulic Lift Lock

    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.

    Changing the Spray Section Position

    Perform the following steps to move the outer spray sections to the SPRAY position:

    1. Park the machine on a level surface.

    2. Use the boom-section lift switches to lower the outer sections.

      Note: Wait until the outer spray sections reach the full, extended spray position.

    Complete the sprayer job, then perform the following steps to retract the outer spray sections into the transport position:

    1. Park the machine on a level surface.

    2. Use the boom-section lift switches to raise one of the outer spray sections.

    3. Use the boom-section lift switches to raise the other outer spray sections.

    4. Raise the sections until they have moved completely into boom-section transport cradles forming the “X” transport position, and the lift cylinders are fully retracted.

      Important: Release the boom-section lift switch(es) once the outer spray sections have reached the desired position. Running the actuators against the mechanical stops may damage the lift cylinders and/or other hydraulic components.

      Important: Ensure that the spray sections do not contact any low overhead objects while in the transport position, this can damage the spray sections.

      Important: The spray sections can be damaged by transporting them in any position other than the “X” transport position using the boom transport cradle.

      g467635

      Figure 75

      “X” transport position

    Important: To prevent damage to the lift cylinder, make sure that the actuators are fully retracted before transporting the machine.

    Spraying Tips

    • Do not overlap areas where you have previously sprayed.

    • Watch for plugged nozzles. Replace all worn or damaged nozzles.

    • Use the master-section 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.

    • You obtain better results if the sprayer is moving when you turn the spray sections 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.

    Unclogging a Nozzle

    If a nozzle becomes clogged while you are spraying, clean the nozzle as follows:

    1. Stop the sprayer on a level surface, shut off the engine, and engage the parking brake.

    2. Set the master section switch to the OFF position and then set the sprayer-pump switch to the OFF position.
