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 (and passenger) should remain seated whenever the machine is in motion. The operator should keep both hands on the steering wheel whenever possible. Keep your arms and legs within the operator’s compartment at all times.

  • Failure to operate the machine 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 machine 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 machine 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 machine 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 machine can produce sparks capable of igniting explosive materials. Never operate the machine 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 shut off. 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 machine for damage. Repair all damage before resuming operation.

  • Before getting off the seat:

    1. Stop the machine.

    2. Remove your foot from the traction pedal and engage the parking brake.

    3. Turn the key for the starter switch to the OFF position.

    4. Remove the key from the starter switch.

      Important: Do not park the machine on an incline.

  • Lightning can cause severe injury or death. If lightning is seen 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 machine 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 machine 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 that 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 machine on a hill may cause tipping or rolling of the machine, or the engine may stall and you could lose headway on the hill. This could result in personal injury.

  • Do not accelerate quickly or suddenly apply 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 takes longer than stopping on level ground. If you must stop the machine, avoid sudden speed changes, which may initiate tipping or rolling of the machine. Do not suddenly apply the brakes when rolling backward, as this may cause the machine 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 machine to become unstable.

    Warning

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

    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 center of gravity of the machine and the handling of it. To avoid loss of control and personal injury, follow these guidelines:

  • 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 machine 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 machine.

  • Before performing any maintenance, ensure that the system has been thoroughly rinsed and cleaned.

  • Before servicing or making adjustments to the machine, shutoff the engine, engage the parking brake, and remove the key 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 you must run the engine 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 traction control speed. To ensure safety and accuracy, have an Authorized Toro Distributor check the ground speed.

  • Keep your body and hands away from pinhole 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 machine in any manner that may affect machine operation, performance, durability, or its use, may result in injury or death. Such use could void the product warranty.

    In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel 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 fuel that spills.

    • Do not fill the fuel tank completely full. Add fuel to the fuel tank until the level is 25 mm (1 inch) below the bottom of the filler neck. This empty space in the tank allows fuel to expand.

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

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

    Danger

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

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

    • Do not fill fuel 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 gasoline-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 fuel dispenser nozzle.

    • If you must use a fuel dispenser nozzle, 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 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 you use a fuel stabilizer.

    • Do not add oil to gasoline.

    Filling the Fuel Tank

    Fuel tank capacity: approximately 45 L (12 US gallons).

    1. Park the machine on a level surface, engage the parking brake, shut off the spray pump, shut off the engine, remove the key, and allow the engine to cool.

    2. Clean the area around the fuel-tank cap (Figure 19).

    After the first 100 hours
  • Follow the guidelines for breaking in a new sprayer.
    • Check the engine-oil and fluid levels regularly and be alert for indications of overheating in any component of the sprayer.

    • After filling the tank, check the tank straps for any play. Tighten as necessary; refer to Inspecting the Tank Straps.

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

    • Avoid hard-braking situations for the first several hours of new sprayer break-in operation. New brake linings may not give optimum performance until several hours of use has caused the brakes to become burnished (broken-in).

    • Avoid racing the engine.

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

    Operating the Sprayer

    To operate the Multi Pro® Sprayer, first fill the sprayer tank, apply the product mix to the job site, and finally clean the tank and spray system. 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 sprayer tank at night and then spray in the morning. This leads to separation of the chemicals and 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 provide 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 sprayer and spray system thoroughly after all applications. This ensures that your sprayer has a long and trouble-free life.

    Note: If you have questions or need additional information regarding the spray-control system, refer to the Operator’s Manual supplied with the system.

    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 ROPS, behind the passenger seat (Figure 25).

    Note: 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 fill the tank, unscrew the cap on the top of the tank, fill the tank with fresh water, and tighten the cap.

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

    g032530

    Filling the Spray Tank

    Important: Ensure that the chemicals you use are compatible 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: The tank-volume markings are for reference only and cannot be considered accurate for calibration.

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

    1. Stop the machine on a level surface, shut off the engine, and engage 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.

      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 under the tank cover and clean the strainer.

    4. Assemble the fill hose to the quick disconnect fitting of the anti-siphon fill receptacle.

    5. Add 3/4 of the required water to the spray tank (Figure 26).

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

      g191616
    6. Start the engine, engage the parking brake, set the spray-pump switch to the ON position, and move the throttle lever to HIGH IDLE.

    7. Set the agitation switch to the ON position.

      Important: Prior to introducing wettable powders into any Toro Spray System mix the powders in a suitable container with sufficient fresh water to create a free flowing slurry. Failure to do so may result in chemical deposits on the bottom of the tank, degraded agitation, clogging of filters, and improper application rates.Toro recommends using the approved Eductor Kit for this machine. Contact your Authorized Toro Dealer for more information.

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

    9. Add the remaining water to the tank, remove the fill hose, and close the tank cover.

      Note: To seal the tank, close the cover and rotate the front half clockwise.

    Operating 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.

    1. Stop the sprayer on level ground.

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

      Note: Wait until the sections reach the fully-extended spray position.

    3. When you need to raise the spray sections, stop the sprayer on level ground.

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

      Note: Raise the sections until they have moved completely into section transport cradle, forming the “X” transport position and the section cylinders are fully retracted.

    Important: To prevent damage to the section-actuator cylinder, ensure that the actuators are fully retracted before transport.

    Important: Release the actuator switch once the sections have reached the desired position. Running the actuators against the mechanical stops may damage the lift cylinders and/or other hydraulic components.

    Operating 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 section(s) can be pushed out of the transport cradles. If this occurs, the boom sections will come to rest in a near-horizontal position to the rear of the vehicle. While this movement will not damage the outer boom sections, they should be immediately put back into the transport cradle.

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

    To put the boom sections back into the transport cradle, lower the boom section(s) to the spray position, and then raise the boom section(s) back into the transport position. Ensure that the lift cylinders are fully retracted to prevent actuator rod damage during storage.

      • Calibrate the agitation bypass valve, or replace worn nozzles and calibrate the agitation bypass valve; refer to Calibrating the Agitation-Bypass Valve.

    Taking Proper Turf Care Precautions while Operating in Stationary Modes

    Important: Under some conditions, heat from the engine, radiator, and muffler can 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 very 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 the machine is left running over any particular area of turf. Both time and temperature affect how much the grass may be damaged.

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

    Spraying Tips

    • Do not overlap areas that 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 it stops, use the engine-throttle control 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 spray sections on.

    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.

    3. Remove the clogged nozzle and clean it using a spray bottle of water and a toothbrush.

    4. Install the nozzle.

    Selecting a Nozzle

    Note: Refer to the nozzle-selection guide that is available through your Authorized Toro Dealer.

    The turret bodies can accept up to 3 different nozzles. To select the desired nozzle perform the following:

    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 set the spray-pump switch to the OFF position.

    3. Rotate the turret of the nozzles in either direction to the correct nozzle.

    4. For machines operated in the application rate mode, perform a flow calibration; refer to the Software Guide for the Multi Pro 5800-D and 5800-G turf sprayers with ExcelaRate spray system.

    Cleaning the Sprayer System

    Draining the Tank

    1. Stop the sprayer, engage the parking brake, and shut off the engine.

    2. Locate the tank-drain valve at the left, rear fender of the machine (Figure 36).
