Safe Operating Practices

Warning

The Workman equipped with a spray system is an off-highway vehicle only and is not designed, equipped, or manufactured for use on public streets, roads, or highways.

Do not drive the workman on public streets, roads, or highways.

The Workman was designed and tested to offer safe service when operated and maintained properly. Although hazard control and accident prevention partially are dependent upon the design and configuration of the machine, these factors are also dependent upon the awareness, concern, and proper training of the personnel involved in the operation, maintenance and storage of the machine. Improper use or maintenance of the machine can result in injury or death.

This is a specialized utility vehicle designed for off–road use only. Its ride and handling will have a different feel than what drivers experience with passenger cars or trucks. So take time to become familiar with your Workman.

Not all of the attachments that adapt to the Workman are covered in this manual. See the Operator’s Manual provided with attachment for additional safety instructions.

Supervisor's Responsibilities

  • Make sure that operators are thoroughly trained and familiar with the Operator’s Manual, Training Material, Engine Manual, and all labels on the Workman vehicle.

  • Be sure to establish your own special procedures and work rules for unusual operating conditions (e.g. slopes too steep for vehicle operation). Use the third high lockout switch if high speed could result in a safety or vehicle abuse situation.

Chemical Safety

Warning

Chemical substances used in the spray system may be hazardous and toxic to you, bystanders, animals, plants, soils or other property.

  • Carefully read and follow the chemical warning labels and Material Safety Data Sheets (MSDS) for all chemicals used and protect yourself according to the chemical manufacturer's recommendations. For example, use appropriate Personal Protective Equipment (PPE) including face and eye protection, gloves, or other equipment to guard against personal contact with the chemical.

  • Keep in mind that there may be more than one chemical used, and information on each chemical should be assessed.

  • Refuse to operate or work on the sprayer if this information is not available!

  • Before working on a spray system, make sure that the system has been triple rinsed and neutralized according to the recommendations of the chemical manufacturer(s) and all of the valves have been cycled 3 times.

  • Verify there is an adequate supply of clean water and soap nearby, and immediately wash off any chemicals that contact you.

  • Obtain proper training before using or handling chemicals.

  • Use the correct chemical for the job.

  • Follow the chemical manufacturer's instructions for the safe application of the chemical.

  • Handle chemicals in a well ventilated area.

  • Wear goggles and other protective equipment as instructed by the chemical manufacturer. Ensure that as little skin as possible is exposed while using chemicals.

  • Have clean water available especially when filling the spray tank.

  • Do not eat, drink, or smoke while working with chemicals.

  • Always wash your hands and other exposed areas as soon as possible after finishing the work.

  • Properly dispose of unused chemicals and chemical containers as instructed by the chemical manufacturer and your local codes.

  • 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. Only trained and authorized persons should operate this sprayer. Make sure that all operators are physically and mentally capable of operating the sprayer.

  • This vehicle is designed to carry the operator and one passenger in the seat provided by the manufacturer. Never carry any other passengers on the vehicle.

  • Never operate the sprayer when under the influence of drugs or alcohol. Even prescription drugs and cold medicines can cause drowsiness.

  • Do not drive the sprayer when you are tired. Be sure to take occasional breaks. It is very important that you stay alert at all times.

  • Become familiar with the controls and know how to stop the engine quickly.

  • Keep all shields, safety devices, and decals in place. If a shield, safety device, or decal is malfunctioning, illegible, or damaged, repair or replace it before operating the machine.

  • Always wear substantial shoes. Do not operate the machine while wearing sandals, tennis shoes, or sneakers. Do not wear loose fitting clothing or jewelry which could get caught in moving parts and cause personal injury.

  • Wearing safety glasses, safety shoes, long pants, and a helmet is advisable and required by some local safety and insurance regulations.

  • Keep everyone, especially children and pets, away from the areas of operation.

  • Be extremely careful when operating around people. Always be aware of where bystanders might be and keep them away from the work area.

  • Before operating the vehicle, always check all parts of the vehicle and any attachments. If something is wrong, stop using the vehicle. Make sure that the problem is corrected before vehicle or attachment is operated again.

  • Since gasoline is highly flammable, handle it carefully.

    • Use an approved gasoline container.

    • Do not remove the cap from the fuel tank when the engine is hot or running.

    • Do not smoke while handling gasoline.

    • Fill the fuel tank outdoors, and fill it to about 25 mm (1 inch) below the top of the tank (the bottom of the filler neck). Do not overfill it.

    • Wipe up any spilled gasoline.

  • Use only an approved non-metal, portable fuel container. Static electric discharge can ignite gasoline vapors in a ungrounded fuel container. Remove the fuel container from the bed of the vehicle and place on the ground away from the vehicle before filling. Keep nozzle in contact with container while filling.

  • Check the safety interlock system daily for proper operation. If a switch should malfunction, replace the switch before operating machine.

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.

  • Operator and passenger should remain seated whenever the vehicle is in motion. Operator should keep both hands on steering wheel, whenever possible and passenger should use hand holds provided. Keep arms and legs within the vehicle body at all times. Never carry passengers in the box or on attachments. Remember your passenger may not be expecting you to brake or turn and may not be ready.

  • Always watch out for and avoid low overhangs such as tree limbs, door jambs, and over-head walkways. Make sure there is enough room over head to easily clear the vehicle, sprayer booms and your head.

  • When starting the engine:

    • Sit on operator’s seat and ensure parking brake is engaged.

    • Disengage PTO and return hand throttle lever to Off position.

    • Move shift lever to Neutral and depress clutch pedal.

    • Keep foot off accelerator pedal.

    • Turn ignition key to Start.

  • Using the machine demands attention. Failure to operate vehicle safely may result in an accident, tip 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. Reduce speed when making sharp turns or when turning on hillsides. Avoid turning on hillsides whenever possible.

    • Use extra caution when operating vehicle on wet surfaces, at higher speeds or with a full load. Stopping time will increase with a full load. Shift into a lower gear before starting up or down a hill.

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

    • Do not attempt sharp turns or abrupt maneuvers or other unsafe driving actions that may cause a loss of vehicle control.

    • Do not pass another vehicle traveling in the same direction at intersections, blind spots, or at other dangerous locations.

    • When draining, do not let anyone stand behind vehicle and do not drain liquid on any one’s feet.

    • Keep all bystanders away. Before backing up, look to the rear and assure no one is behind. Back up slowly.

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

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

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

  • Do not use a cab on a Workman vehicle equipped with a spray system. The cab is not pressurized and will not provide adequate ventilation when used with a sprayer. The cab will also overload the vehicle when the spray system tank is full.

  • Do not touch engine, transaxle, muffler or muffler manifold while engine is running or soon after it has stopped because these areas may be hot enough to cause burns.

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

  • Before getting off the seat:

    • Stop movement of the machine.

    • Shut engine off and wait for all movement to stop.

    • Set parking brake.

    • Remove key from ignition.

    Note: Block wheels if machine is 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 vehicle and its contents. More important, it can injure you and your passenger.

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

  • Turf and pavement are slick 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.

Operating on Hills and Rough Terrain

Operating the vehicle on a hill may cause tipping or rolling of the vehicle, 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.

Loading

The weight of the cargo can change the Workman center of gravity and 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 vehicle.

  • 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 vehicle 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 vehicle.

  • 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.

  • Empty the tank before tilting or removing sprayer from vehicle and before storage.

  • Never work under a sprayer without using tank support prop rod.

  • Make sure all hydraulic line connectors are tight, and all hydraulic hoses and lines are in good condition before applying pressure to the system.

  • Keep body and hands away from pin hole leaks that can eject hydraulic fluid under high pressure. Use paper or cardboard, not hands, to search for leaks.

    Danger

    Hydraulic fluid escaping under pressure can have sufficient force to penetrate skin and do serious damage.

    If fluid is injected into the skin it must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.

  • Before disconnecting or performing any work on the hydraulic system, all pressure in system must be relieved by stopping engine, cycling dump valve from raise to lower and/or lowering the tank and attachments. If the tank must be in the raised position, secure it with the safety support.

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

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

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

  • Do not overspeed engine by changing governor settings. Maximum engine speed is 3650 rpm. To assure safety and accuracy, have an Authorized Toro Distributor check maximum engine speed with a tachometer.

  • 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 vehicle in any manner may affect the vehicle’s operation, performance, durability or its use may result in injury or death. Such use could void the product warranty of The Toro® Company.

  • This vehicle should not be modified without The Toro® Company’s authorization. Direct any inquiries to The Toro® Company, Commercial Division, Vehicle Engineering Dept., 300 West 82nd St., Bloomington, Minnesota 55420–1196. USA

  • Refer to your vehicle’s Operator’s Manual for other maintenance.

If you install the sonic-boom and/or the foam-marker kit, you will add switches to the control panel for controlling their operation. The sprayer comes with plastic plugs in these locations.

Regulating (Rate Control) Valve

This valve, located behind the tank (Figure 31), controls the amount of fluid that is routed to the booms by directing fluid flow to the boom.

g022362

Flowmeter

The flowmeter measures the flow rate of the fluid (Figure 31).

Boom Valves

These valves turn the three booms on or off (Figure 31).

Boom-bypass Valves

The boom-bypass valves redirect the fluid flow from a boom to the tank when you turn off the boom section. You can adjust these valves to ensure that the boom pressure remains constant no matter how many booms are on. Refer to Calibrating the Boom Bypass.

Agitation-throttle Valve

This valve is located on the rear left side of the tank (Figure 32). Turn the knob on the valve to the 6 o'clock position to turn on the tank agitation and to the 8 o'clock position to turn off the tank agitation.

g022363

Note: For agitation to work, the PTO and clutch must be engaged, and the engine must be running above an idle. If you stop the sprayer and need agitation on, place the range shift lever in the Neutral position, let out the clutch, set the parking brake, and set the hand throttle (if equipped).

Tank-drain Handle

The tank-drain handle is located on the left side of the machine (Figure 33). To open the tank drain, turn the handle to the 3 o’clock position. To close the drain, turn the handle to the 12 o’clock position.

Operation

Note: Determine the left and right sides of the machine from the normal operating position.

Note: If you ever need to transport the vehicle on a trailer with the sprayer attached, make sure the booms are tied down and secure.

Think 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.

Filling the Fresh Water Tank

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

The sprayer is equipped with a fresh water tank. It supplies a source of fresh water for you to wash chemicals off your skin, eyes, or other surfaces in the case of accidental exposure.

To open the fresh water tank spigot, turn the spigot lever towards the front of the sprayer.

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 34).

    g013780
  3. Lift up on the boom and remove the pin (Figure 34), 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 35).

    g014220
  6. Turn the eyelet rod in the actuator rod to shorten or lengthen the extended actuator to the desired position (Figure 35).

    Note: You must turn the eyelet rod in half or complete revolutions so that you can assemble 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.

  9. While holding the boom, insert the pin through both boom pivot and actuator rod (Figure 34).

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

  11. Repeat the procedure for each actuator rod bearing, if necessary.

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 lead to separation of the chemicals and possible damage to 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 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.

Remember to clean your sprayer thoroughly after all applications. This will do the most to ensure your sprayer has a long and trouble free life.

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

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

  3. Open the tank cover on the spray tank.

    The tank lid 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.

  4. 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.

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

  6. Turn the agitation switch on.

  7. 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

  8. Add the remaining water to the tank.

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

Operating the Booms

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

Note: If the sprayer is mounted on a Workman HD/HDX/HDX-D, the vehicle must be locked into bed lift mode.

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 (Figure 36).

    g255717
  2. Move the hydraulic-lift lock left to engage the lock (Figure 36).

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 transporting the machine.

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: In order to ensure that your solution remains well mixed, use the agitation feature whenever you have solution in the tank. For agitation to work, the PTO must be engaged and the engine must be running above an idle. If you stop the vehicle and need agitation on, place the shift lever in the Neutral position, set 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 and the boom valve calibration has been completed.

  1. Lower the booms into position.

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

  3. Set the individual boom switches, as needed, to the On positions.

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

  5. Navigate to the Application Rate screen on the InfoCenter and set the desired rate. To do this:

    1. Ensure that the pump is On.

    2. Select the desired gear range and begin driving to your target.

    3. Verify that the monitor displays the correct application rate. If needed, manipulate the application rate switch until the monitor displays the desired application rate.

    4. Return to the location where spraying is to begin.

  6. Set the master boom switch to the On position to 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 boom switch to the Off position to turn off all booms, then disengage the PTO lever.

Spraying Tips

  • Do not overlap areas where 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, 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.

  2. Use the tank drain valve to drain any unused material from the tank and dispose of it according to local codes and the material manufacturer's instructions.

    The tank drain is located on the left side of the machine (Figure 37).

    g022364
  3. Fill the tank with at least 190 L (50 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.

  4. Start the engine.

  5. With the shift lever in the Neutral position, engage the PTO, and set the hand throttle.

  6. Ensure that the agitation control valve is in the On position.

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

  8. Allow the water in the tank to spray out though the nozzles.

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

  10. Set the master boom switch to the Off position, disengage the PTO, and stop the engine.

  11. Repeat steps 3 through 10 at least 2 more times to ensure that the spray system is fully cleaned.

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

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

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

  14. Remove the nozzles and clean them by hand. Replace damaged or worn nozzles.
