While Operating

Warning

Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you.

Do not run engine indoors or in an enclosed area.

  • The operator should remain seated whenever the sprayer is in motion. The operator should keep both hands on the steering wheel whenever possible. Keep your arms and legs within the sprayer body at all times.

  • Failure to operate the sprayer safely may result in an accident, tip over of the sprayer, 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, unfamiliar areas, or any areas that have abrupt changes in ground conditions or elevation.

    • Watch for holes or other hidden hazards.

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

    • Avoid sudden stops and starts. Do not go from reverse to forward or forward to reverse without first coming to a complete stop.

    • Slow down before turning. Do not attempt sharp turns or abrupt maneuvers or other unsafe driving actions that may cause a loss of sprayer control.

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

    • Watch out for traffic when you are near or crossing roads. Always yield the right of way to pedestrians and other vehicles. This sprayer is not designed for use on streets or highways. Always signal your turns or stop early enough so that other people know what you plan to do. Obey all traffic rules and regulations.

    • The electrical and exhaust systems of the sprayer can produce sparks capable of igniting explosive materials. Never operate the sprayer in or near an area where there is dust or fumes in the air which are explosive.

    • If you are ever unsure about safe operation, stop work and ask your supervisor.

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

  • If the machine ever vibrates abnormally, stop immediately, wait for all motion to stop, and inspect the sprayer for damage. Repair all damage before resuming operation.

  • Before getting off of the seat:

    1. Stop the movement of the machine.

    2. Place the range selector in Neutral and set the parking brake.

    3. Turn the ignition key to Off.

    4. Remove the ignition key.

      Important: Do not park the machine on an incline.

  • Lightning can cause severe injury or death. If lightning is seen or thunder is heard in the area, do not operate the machine; seek shelter.

Braking

  • Slow down before you approach an obstacle. This gives you extra time to stop or turn away. Hitting an obstacle can damage the sprayer and its contents. More important, it can injure you.

  • Gross Vehicle Weight (GVW) has a major impact on your ability to stop and/or turn. Heavy loads and attachments make a sprayer harder to stop or turn. The heavier the load, the longer it takes to stop.

  • Turf and pavement are much more slippery when they are wet. It can take 2 to 4 times as long to stop on wet surfaces as on dry surfaces. If you drive through standing water deep enough to get the brakes wet, they will not work well until they are dry. After driving through water, you should test the brakes to make sure they work properly. If they do not, drive slowly while putting light pressure on the brake pedal. This will dry the brakes out.

ROPS Safety

Note: For each machine covered in this Operator’s Manual, a cab installed by Toro is a ROPS.

  • Do not remove the ROPS from the machine.

  • Fasten the seat belt and ensure that you can release it quickly in an emergency. Always wear your seat belt when the roll bar is up or on a machine with a cab installed by Toro.

  • Check carefully for overhead obstructions and do not contact them.

  • Keep the ROPS in safe operating condition by thoroughly inspecting it periodically for damage and keeping all the mounting fasteners tight.

  • Replace any damaged ROPS component. Do not repair or alter it.

Operating on Hills and Rough Terrain

Operating the sprayer on a hill may cause tipping or rolling of the sprayer, or the engine may stall and you could lose headway on the hill. This could result in personal injury.

  • Do not accelerate quickly or slam on the brakes when backing down a hill, especially with a load.

  • Never drive across a steep hill; always drive straight up or down or go around the hill.

  • If the engine stalls or you begin to lose headway while climbing a hill, gradually apply the brakes and slowly back straight down the hill.

  • Turning while traveling up or down hills can be dangerous. If you have to turn while on a hill, do it slowly and cautiously. Never make sharp or fast turns.

  • Heavy loads affect stability. Reduce the weight of the load and your speed when operating on hills.

  • 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. Do not slam on the brakes when rolling backward, as this may cause the sprayer to overturn.

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

    Warning

    Sudden changes in terrain may cause abrupt steering wheel movement, possibly resulting in hand and arm injuries.

  • Reduce your speed when operating on rough terrain and near curbs.

  • Grip the steering wheel loosely around the perimeter. Keep your hands clear of the steering wheel spokes.

Loading

The weight of the cargo can change the sprayer center of gravity and sprayer handling. To avoid loss of control and personal injury, follow these guidelines:

  • Reduce the weight of the load when operating on hills and rough terrain to avoid tipping or overturning of the sprayer.

  • Liquid loads can shift. This shifting happens most often while turning, going up or down hills, suddenly changing speeds, or while driving over rough surfaces. Shifting loads can cause the sprayer to tip over.

  • When operating with a heavy load, reduce your speed and allow for sufficient braking distance. Do not suddenly apply the brakes. Use extra caution on slopes.

  • Be aware that heavy loads increase your stopping distance and reduce your ability to turn quickly without tipping over.

Maintenance

  • Only permit qualified and authorized personnel to maintain, repair, adjust, or inspect the sprayer.

  • Before servicing or making adjustments to the machine, stop the engine, set the parking brake, and remove the key from the ignition to prevent someone from accidentally starting the engine.

  • To make sure that the entire machine is in good condition, keep all nuts, bolts, and screws properly tightened.

  • To reduce the potential for fire, keep the engine area free of excessive grease, grass, leaves, and accumulation of dirt.

  • Never use an open flame to check the level or leakage of fuel or battery electrolyte.

  • If the engine must be running to perform a maintenance adjustment, keep your hands, feet, clothing, and any parts of your body away from the engine and any moving parts. Keep everyone away.

  • Do not use open pans of fuel or flammable cleaning fluids when cleaning parts.

  • Do not adjust the ground speed governor. To ensure safety and accuracy, have an Authorized Toro Distributor check the ground speed.

  • Keep your body and hands away from pin hole leaks or nozzles that eject high pressure fluid. Use cardboard or paper to find leaks. Fluid escaping under pressure can penetrate skin and cause injury requiring surgery within a few hours by a qualified surgeon; otherwise, gangrene may result.

  • If major repairs are ever needed or assistance is required, contact an Authorized Toro Distributor.

  • To be sure of optimum performance and safety, always purchase genuine Toro replacement parts and accessories. Replacement parts and accessories made by other manufacturers could be dangerous. Altering this sprayer in any manner that may affect sprayer operation, performance, durability, or its use, may result in injury or death. Such use could void the product warranty.

Safety First

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

Preparing to Drive the Sprayer for the First Time

Checking the Engine Oil

The engine is shipped with oil in the crankcase; however, the level of oil must be checked before you first start the engine and after you have run it.

  1. Position the machine on a level surface.

  2. Remove the dipstick and wipe it with a clean rag (Figure 11).

  3. Insert the dipstick into the tube and make sure it is seated fully. Remove the dipstick and check the oil level.

    g023037
  4. If the oil level is low, remove the filler cap from the valve cover (Figure 11) and pour oil into the opening until the oil level is up to the Full mark on the dipstick; refer to Changing the Engine Oil for the proper oil type and viscosity. Add the oil slowly and check the level often during this process. Do not overfill.

  5. Install the dipstick firmly in place.

Checking the Tire Pressure

Check the tire pressure every 8 hours or daily to ensure proper levels. Fill the tires to 138 kPa (20 psi). Also, check the tires for wear or damage.

Adding Fuel

Danger

In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property.

  • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills.

  • Never fill the fuel tank inside an enclosed trailer.

  • Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.

  • Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by a spark.

  • Store gasoline in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of gasoline.

  • Do not operate without entire exhaust system in place and in proper working condition.

Danger

In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property.

  • Always place gasoline containers on the ground away from your vehicle before filling.

  • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

  • When practical, remove gas-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

  • If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.

  • If a gasoline dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

Recommended Fuel

  • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

  • ETHANOL: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol ). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty

  • Do not use gasoline containing methanol.

  • Do not store fuel either in the fuel tank or fuel containers over the winter unless a fuel stabilizer is used.

  • Do not add oil to gasoline.

Filling the Fuel Tank

The fuel tank capacity is approximately 19 L (5 US gallons).

Note: The fuel tank cap contains a gauge which shows the fuel level; check it frequently.

  1. Shut the engine off and set the parking brake.

  2. Clean the area around the fuel-tank cap (Figure 12).

    g023038
  3. Remove the fuel tank cap.

  4. Fill the tank to about one inch below the top of the tank, (bottom of the filler neck). This space in the tank allows gasoline to expand. Do not overfill.

  5. Install the fuel-tank cap securely.

  6. Wipe up any fuel that may have spilled.

Performing the Pre-Starting Checks

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.

  • 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.

Adjusting the Booms to Level

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).

    g013780
  3. Lift up on the boom and remove the pin (Figure 13), and slowly lower the boom to the ground.

  4. Inspect the pin for any damage, and replace it if necessary.

  5. Use a wrench on the flat sides of the actuator rod to immobilize it, then loosen the jam nut to allow the eyelet rod to be manipulated (Figure 14).

    g014220
  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.

Operating the Sprayer

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.

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 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.

Filling the Fresh Water Tank

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.

Filling the Spray Tank

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.

Operating the Booms

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.

Changing the Boom Position

  1. Stop the sprayer on level ground.

  2. Use the boom lift switches to lower the booms.

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

  3. When the booms need to be retracted, stop the sprayer on level ground.

  4. Use the boom lift switches to raise the booms, until they have moved completely into boom transport cradle forming the “X” transport position and the boom cylinders are fully retracted.

    Important: To prevent damage to the boom actuator cylinder, make sure that the actuators are fully retracted before transport.

Using the Boom Transport Cradle

The sprayer is equipped with a boom transport cradle that has a unique safety feature. In the event of accidental boom contact with a low overhead object while in the transport position, the boom(s) can be pushed out of the transport cradles. If this occurs, the booms will come to rest in a near horizontal position to the rear of the vehicle. While the booms will not be damaged due to this movement, they should be immediately put back into the transport cradle.

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

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. Make sure that the boom cylinders are fully retracted to prevent actuator rod damage.

Spraying

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.

Spraying Tips

  • 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.

Cleaning the Sprayer

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.

    g023039
  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.
