  • This machine was designed for one operator only. Do not carry passengers.

  • Wear appropriate personal protective equipment such as safety glasses, long pants, substantial slip-resistant footwear, and hearing protection. Tie back long hair and avoid loose clothing and loose jewelry which may get tangled in moving parts.

  • This machine produces sound levels in excess of 85dBA at the operator’s ear and can cause hearing loss through extended periods of exposure. Wear hearing protection when operating this machine.

  • Check that the following items are in place and in proper working condition: the operator presence controls, safety switches, guards, and shields. Do not operate the machine unless they are in proper working condition. Replace worn or deteriorated parts with genuine Toro parts when necessary.

    Danger

    It is essential that operator safety mechanisms be connected and in proper operating condition prior to use.

    Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. When the key is turned to the OFF position, the engine should shut off. If not, stop using the machine immediately and contact an Authorized Service Dealer.

  • Do not operate the machine when people, especially children, or pets are in the area. Shut off the machine and attachment(s) if anyone enters the area.

  • Do not operate the machine without the safety devices in place and in proper working condition. Components are subject to wear, damage and deterioration, which could expose moving parts or allow objects to be thrown. Frequently check for worn or deteriorating components and replace them with the manufacturer’s recommended parts when necessary.

  • Do not fill, calibrate, or clean the machine when people, especially children, or pets are in the area.

  • Check all sprayer components for wear and leaks before applying pressure to the system. Do not use if leaking or damaged.

  • Make sure the operator platform is clean and free from chemical residue and debris buildup.

Chemical Safety

Warning

Chemical substances used in the spreader-sprayer 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. Ensure that as little skin as possible is exposed while using chemicals. Use appropriate Personal Protective Equipment (PPE) to guard against personal contact with chemicals, such as:

    – safety glasses, goggles, and/or face shield

    – chemical resistant gloves

    – rubber boots or other substantial footwear

    – hearing protection

    – respirator or filter mask

    – clean change of clothes, soap, and disposable towels, to be kept on-hand, in the event of a chemical spill.

  • 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 spreader-sprayer if this information is not available!

  • Before working on a spreader-sprayer 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 three times.

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

Fuel Safety

Danger

Gasoline is extremely flammable and vapors are explosive.

A fire or explosion from gasoline can burn you, others, and cause property damage.

  • Fill the fuel tank outdoors on level ground, in an open area, when the engine is cold. If fuel is spilled, do not attempt to start the engine. Move away from the area of the spill and avoid creating any source of ignition until fuel vapors have dissipated.

  • Do not refill the fuel tank or drain the machine indoors or inside an enclosed trailer.

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

  • Add fuel before starting the engine. Never remove the cap of the fuel tank or add fuel when engine is running or when the engine is hot.

  • Store gasoline in an approved container and keep it out of the reach of children.

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

Caution

Refueling engine is difficult especially when using a larger refueling container—19 L (5 US gallons).

When refueling, it is recommended to:

  • Use a smaller container—4-8 L (1-2 US gallons).

  • Use a funnel.

  • In certain conditions during fueling, static electricity can be released causing a spark which can ignite gasoline vapors.

    • Do not fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground and away from your vehicle before filling.

    • 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 is used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock open device.

  • Do not overfill the fuel tank. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows gasoline to expand. Overfilling may result in fuel leakage or damage to the engine or emission system.

  • Gasoline is harmful or fatal if swallowed. Long-term exposure to vapors may cause serious injury and illness.

    • Avoid prolonged breathing of vapors.

    • Keep face away from nozzle and gas tank/container opening.

    • Keep away from eyes and skin.

  • To help prevent fires:

    • Keep engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris which can accumulate in these areas.

    • Clean up oil and fuel spills and remove fuel soaked debris.

    • Allow the machine to cool before storing the machine in any enclosure. Do not store the machine or fuel container, or refuel, where there is an open flame, spark, or pilot light such as on a water heater or other appliance.

Fuel Specification

Petroleum fuelUse unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).
Ethanol blended fuelUse of an oxygenated, unleaded-gasoline blend with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same.
Do not use ethanol blends of gasoline (such as E15 or E85) with more than 10% ethanol by volume. Performance problems and/or engine damage may result which may not be covered under warranty.

Important: For best results, use only clean, fresh fuel (less than 30 days old).

  • 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.

During Operation

During Operation Safety

General Safety

The operator must use their full attention when operating the machine. Do not engage in any activity that causes distractions; otherwise, injury or property damage may occur.

Warning

Operating engine parts, especially the muffler, become extremely hot. Severe burns can occur on contact and debris, such as leaves, grass, brush, etc. can catch fire.

Clean the machine as stated in the Maintenance section. Keep engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris which can accumulate in these areas.

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, gloves, and any other protective equipment recommended by the chemical manufacturer.

  • Operate the engine only in well-ventilated areas. Exhaust gases contain carbon monoxide, which is an odorless deadly poison.

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

  • Operate the machine only in good visibility and appropriate weather conditions. Do not operate the machine when there is the risk of lightning.

  • Keep away from holes, ruts, bumps, rocks, and other hidden hazards. Use care when approaching blind corners, shrubs, trees, tall grass or other objects that may hide obstacles or obscure vision. Uneven terrain could overturn the machine.

  • Start the engine with your feet well away from the spreader or spray nozzles.

  • Be aware of weather conditions and check that spray nozzles, patterns, and volume are suitable.

  • Do not operate the machine without all safety shields, guards, switches, and other devices in place and in proper working condition.

  • Keep clear of the discharge area at all times.

  • Keep hands and feet away from moving parts. If possible, do not make adjustments with engine running.

  • Be aware of the spreading/spraying path and direct discharge away from others. Avoid discharging material against a wall or obstruction as the material may ricochet back toward the operator.

  • Be alert, slow down and use caution when making turns. Do not operate in reverse unless absolutely necessary. Always look down and behind you before moving the machine in reverse.

  • Stop spreading/spraying when making tight turns to minimize uneven distribution pattern, application rate, and chemical drift.

  • Chemicals may drift and cause injury to people and animals. It may also damage plants, soil, or other property.

  • Park the machine on level ground. Stop engine, wait for all moving parts to stop, and remove the key.

    • Before checking, cleaning or working on the machine.

    • After striking a foreign object or an abnormal vibration occurs (inspect the machine for damage and make repairs before restarting and operating the machine).

    • Before clearing blockages.

    • Whenever you leave the machine. Do not leave a running machine unattended.

  • Stop the engine, wait for all moving parts to stop:

    – Before refueling.

  • Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the spreading/spraying activity. Never assume that children will remain where you last saw them.

    • Keep children out of the working area and under the watchful care of another responsible adult, not the operator.

    • Be alert and turn the machine off if children enter the area.

    • Before and while backing or changing direction, look behind, down, and side-to-side for small children.

    • Never allow children to operate the machine.

    • Do not carry children, even with the spreading/spraying shut off. Children could fall off and be seriously injured or interfere with the safe operation of the machine. Children that have been given rides in the past could suddenly appear in the working area for another ride and be run over or backed over by the machine.

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

  • Liquid loads and granular materials 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 stopping distance. Use extra caution on slopes.

  • 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 speed when operating on rough terrain or near curbs.

  • Safely relieve liquid from spray wand every time engine is turned off.

    Warning

    Spray wand traps liquids under high pressure, even when engine is off. High pressure spray discharge could cause serious injury or death.

    • Keep clear of nozzle and do not direct spray or stream at people, pets, or non-work area property.

    • Do not direct spray on or near electrical power components or source.

    • Do not repair spray wand, hoses, seals, nozzle, or other wand components; replace them.

    • Do not attach hoses or other components to the end of the spray wand nozzle.

    • Do not attempt to disconnect the spray wand from the machine while the system is pressurized.

    • Do not use spray wand if trigger lock is damaged or missing.

    • Do not keep spray wand in locked-open position when job is complete.

  • When draining or relieving system, do not let anyone stand in front of nozzles and do not drain on a person’s feet.

Slope Safety

  • Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. The operator is responsible for safe slope operation. Operating the machine on any slope requires extra caution. Before using the machine on a slope, the operator must:

    • Review and understand the slope instructions in the manual and on the machine.

    • Evaluate the site conditions of the day to determine if the slope is safe for machine operation. Use common sense and good judgment when performing this evaluation. Changes in the terrain, such as moisture, can quickly affect the operation of the machine on a slope.

  • Operate across slopes, never up and down. Avoid operation on excessively steep or wet slopes.

  • Identify hazards at the base of the slope. Do not operate the machine near drop-offs, ditches, embankments, water or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge collapses. Keep a safe distance (twice the width of the machine) between the machine and any hazard. Use a walk-behind machine or a handheld tool to operate in these areas.

    g222400

    3. Water
    4. W=width of the machine
    5. Keep a safe distance (twice the width of the machine) between the machine and any hazard.

  • Avoid starting, stopping or turning the machine on slopes. Avoid making sudden changes in speed or direction; turn slowly and gradually.

  • Do not operate a machine under any conditions where traction, steering or stability is in question. Be aware that operating the machine on wet grass, across slopes or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering. The machine can slide even if the drive wheels are stopped.

  • Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks or other hidden hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine.

  • Use extra care while operating with accessories or attachments. These can change the stability of the machine and cause a loss of control. Follow directions for counter weights.

  • If you lose control of the machine, step off and away from the direction of travel of the machine.

Operating the Machine

Starting the Engine

  1. Leave the motion control levers in neutral and engage the parking brake.

  2. Set the throttle to the FAST position.

  3. On a cold engine, push the choke lever forward into the ON position.

    On a warm engine, leave the choke in the OFF position.

  4. Turn ignition switch to the START position. Release the switch as soon as the engine starts.

    Important: Do not crank the engine continuously for more than ten seconds at a time. If the engine does not start, allow a 60 second cool-down period between starting attempts. Failure to follow these guidelines can burn out the starter motorEngine may be difficult to start in temperatures under -1 °C (30°F).

  5. If the choke is in the ON position, gradually return choke to the OFF position as the engine warms up.

Stopping the Engine

  1. Move the motion control levers back to the neutral position and bring the machine to a full stop.

  2. Engage the parking brake.

  3. Place the throttle midway between the SLOW and FAST positions.

  4. Allow the engine to run for a minimum of 15 seconds, then turn the ignition switch to the OFF position to stop the engine.

  5. Remove the key to prevent children or other unauthorized persons from starting the engine.

Driving the Machine

Caution

Machine can spin very rapidly by positioning one lever too much ahead of the other. Operator may lose control of the machine, which may cause damage to the machine or injury.

  • Use caution when making turns.

  • Slow the machine down before making sharp turns.

Important: To begin movement (forward or backward), the brake lever must be disengaged (pushed forward) before the motion control lever can be moved.

Driving Forward

  1. Make sure the motion control lever is in the neutral position.

  2. Release the parking brake.

  3. To move forward in a straight line, move both levers forward with equal pressure.

    g317102

    Figure 15

    To turn left or right, pull the motion control lever back toward neutral in the desired turn direction.

    The machine will move faster the farther the motion control lever is moved from the neutral position.

  4. To stop, position both motion control levers in the neutral position; releasing the lever will automatically return it to neutral.

    Note: Stopping distance may vary depending on the spreader-sprayer load.

Driving in Reverse

  1. Move the motion control lever to the neutral position.

  2. To move rearward in a straight line, slowly move both levers rearward with equal pressure.

    g317115

    Figure 16

    To turn left or right, release pressure on the motion control lever toward the desired turn direction.

  3. To stop, position both motion control levers in the neutral operate position.

    Note: Stopping distance may vary depending on the spreader-sprayer load.

Adjusting the Front Reference/Speed Control Bar

Adjust the front reference/speed control bar for desired maximum forward speed.

  1. Stop the machine and move the motion control levers to the neutral position.

  2. Loosen the knobs on both sides of the control tower.

    g387111

  3. Move the bar forward to obtain the fastest speed.

    Move the bar backward to obtain the slowest speed.

  4. On both sides, tighten the knobs.

Important: Make sure the knobs are tight so the front reference/speed control bar does not move during operation.

Changing the Platform Suspension

The rubber isolators under the operator platform can be adjusted to make the ride softer or harder. There are three positions: front, middle, and rear.

To make the ride softer move the isolators to the front position.

To make the ride stiffer move the isolators to the rear position.

Operating the Spreader

The spreader disperses free-flowing granular substances such as grass seed, fertilizer, ice melt, etc. When using the spreader, first fill the granule hopper, then apply to the work area, and finally clean the hopper. It is important to complete all three of these steps to avoid damaging the spreader.

Note: Clean your spreader thoroughly after all applications.

Before Operating the Spreader

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.

Make sure the spreader has been calibrated before starting; refer to Spreader Calibration .

Important: Verify that the proper application rate has been set prior to filling the hopper.

Filling the Spreader Hopper

  1. Stop the machine on a level surface, move motion control lever to the neutral position, stop the engine, and set the parking brake.

  2. Use the Spreading Charts on the following pages to determine the rate dial setting.

    Note: If the setting is not listed for the type of material being used, place the setting at a lower value then adjust as needed.

  3. Drive to the work area.

  4. Stop the spreader-sprayer on a level surface, leave motion control lever in the neutral position, stop the engine, and set the parking brake.

  5. Ensure that the hopper gate is closed.

  6. Remove the cover from the hopper, add the material to be spread, and replace the cover.

    Note: Do not overload the hopper; refer to the Maximum Hopper Capacity in Specifications.

    Note: One extra bag of granular product may be placed in each fertilizer box; however, do not exceed the Maximum Machine Weight as stated in Specifications. Overloading the machine will shorten the life of the transmission and void the warranty.

    Note: When operating the machine, maintain a minimum of 60 lb (27 kg) in the hopper when there are 50 lb (23 kg) bags in each fertilizer box.

Spreading

Spreading Tips:

  • To ensure uniform application, be sure to overlap the material distribution. The highest amount of material will dispense from the front of the hopper and less material from each side. Adjust the distribution pattern to achieve desired results.

  • Watch for changes in the distribution pattern; unequal distribution may lead to striping.

Note: Make sure the machine has been calibrated properly before starting the spreading application.

  1. Start the engine and place the throttle midway between the SLOW and FAST positions.

  2. Set the impeller speed to the appropriate broadcast rate setting.

  3. Move the throttle to the FAST position and drive forward.

  4. Pull the Spread Open/Close handle up to open the hopper gate and begin spreading.

    2. Flowers
    3. Side deflector lowered

  5. Evaluate the spread pattern. If adjustments are needed, see Spreader Pattern Adjustment.

  6. When finished spreading, close the hopper gate.

  7. Clean the hopper after each spreading session.

    Important: Always empty and clean the spreader immediately after each use. Failure to do so may cause the chemicals to corrode the spreader and other components.

Cleaning the Spreader

  1. Drive the machine to a designated cleaning area.

  2. Stop the machine on a level surface, leave the motion control lever in the neutral position, and turn off the engine. Engage the parking brake.

  3. Rotate the dial past the “9” position to the maximum open position. Open the hopper gate by pulling the handle up.

    Note: The hopper can be rotated forward to help assist with cleaning; refer to Adjusting the Hopper Position.

  4. Using a garden hose, spray the inside and outside of the entire spreader with clean water.

    Note: Do not use a power washer to clean the machine. The high-pressure water may force residual corrosive materials into spreader-sprayer components.

  5. When the hopper has been thoroughly rinsed and drained, close the gate.

  6. Place the rate dial to a setting lower than the maximum open position.

  7. Allow the spreader-sprayer to completely dry before the next use.

Adjusting the Hopper Position

  • Rotating the hopper forward

    The hopper can be rotated forward for maintenance and cleaning. Before adjusting, make sure side deflector is in the raised position. Pull the hopper latch handle towards the hopper frame tube to unlock the latch and rotate the hopper forward. The prop rod will stop it in the forward position.

    3. Hopper latch handle–locked operating position
    4. Pull latch towards frame
    5. Prop rod

  • Returning the hopper to the operating position

    Slowly rotate the hopper rearward towards the engine. The prop rod has a stop that will prevent the hopper from rotating to the locked operating position.

    1. Pull the hopper slightly forward.

    2. Grab the prop rod close to the detent (see Figure 22) and lift it up towards the hopper frame.

      Important: Do not grab the end of the prop rod located by the engine.

      g416467

      Figure 22

      1. Grab here
      2. Detent
      3. Do Not grab end of prop rod

    3. Push down on the back of hopper until it latches and locks into place.

      Note: Make sure the hopper is securely locked in the down position before driving the machine.

Spreader Calibration

The spreader should be calibrated each time a new material is used. The spread width ranges from 0.9-7.6 m (3-25 ft) and depends on the material particle size, volume/density, and rate of travel.

Refer to the spreading charts along with Determining the Distribution Pattern, Determining the Effective Spreading Width, and Calculating the Application Rate sections to calibrate the machine.

Determining the Distribution Pattern

Operator supplied equipment: 15 shallow collection pans and 15 graduated measuring cylinders

The most accurate method to measure the distribution is to use shallow collection pans and graduated measuring cylinders. In the example below, 15 shallow collection pans approximately 30 cm (12 inches) wide, 91 cm (36 inches) long, and 5 cm (2 inches) tall are used.

  1. Make sure to allow ample driving distance before setting up the pans to ensure the machine is traveling at the desired spreading speed before reaching the pans.

  2. Place one pan in the center of the drive path. Arrange the next two pans, one on each side, far enough apart to allow ample room for the spreader drive tires to pass over the center pan.

  3. Place the remaining pans in a straight line as shown in Figure 23 or Figure 24.

    • For larger granule materials:

      Space six additional pans, on each side, 30 cm (12 inches) apart as shown in Figure 23).

      g319659

      Figure 23

      1. Spreader moving towards pans

      5. L1 and R1 collection pan gap (spread apart to allow machine to pass through)
      6. Graduated measuring cylinder

    • For smaller granule materials:

      Place six additional pans, on each side, with no gap in between each pan (Figure 24).

      g319658

      Figure 24

      1. Spreader moving towards pans

      3. Left collection pans (no gap between each)
      4. Right collection pans (no gap between each)
      5. L1 and R1 collection pan gap (spread apart to allow machine to pass through)
      6. Graduated measuring cylinder

  4. Refer to the Spreading Charts section to determine the appropriate rate dial setting.

  5. Fill the hopper approximately half-full with the desired material.

  6. Set the impeller speed to the appropriate broadcasting rate.

  7. Pull the Spread Open/Close handle to the open position and drive the spreader, at the appropriate speed, over the center pan. Repeat this several times, moving in the same direction each time, until enough material is dispensed to fill the center graduated measuring cylinder half full.

  8. Label each graduated measuring cylinder to correspond with the distribution pans (i.e. ...L2, L1, Center, R1, R2....) (refer to Figure 23 and Figure 24).

  9. One at a time, take a collection pan and dump the contents into the corresponding graduated measuring cylinder. Record the amount of material collected and return the pan to its location. Repeat this until all pan contents have been emptied.

  10. With the graduated measuring cylinder in the same straight line as the pans, evaluate the volume of material in each cylinder to determine the quality of the distribution from the spreader.

  11. To adjust the spreader pattern, refer to Spreader Pattern Adjustment.

  12. Repeat steps 5 through 11 until a uniform pattern is achieved.

Determining the Effective Spreading Width

The effective width is used to determine the uniform distribution of the material.

Note: The spreading width range is 0.9 m (3 ft) up to 7.6 m (25 ft).

  1. After the spreader pattern is correctly adjusted, evaluate the amount of material in the center graduated measuring cylinder.

  2. Locate the two tubes, one each side of center, that contain half the measured amount of the material that you observed in the center graduated cylinder.

  3. Go to the two corresponding pans. Starting from the outer edge, measure and record the distance between left pan, through the center pan, to the outer edge of the right pan.

    Note: This measurement is the effective spreading width.

Calculating the Application Rate

  1. Determine the amount of product to be applied.

  2. Determine the calibration course

    1. Determine the amount of product to be spread per 93 m2 (1,000 ft2). Use the recommended rate from the Spreading Charts section or the product manufacturer’s label as a guide.

    2. Determine a course length by dividing by the effective spread width.

      For example, if the effective width is 1.8 m (6 ft), then the calibration course length equals 51 m (167 ft).

      Course Length

       93 m2 (1,000 ft2)=51 m (167 ft)
        1.8 m (6 ft)

    3. The calibration course is 1.8 m (6 ft) by 51 m (167 ft).

    4. Measure and visibly mark the course length. Make sure to allow ample distance before the starting marker to ensure the spreader is at full speed when crossing the first mark of the course.

  3. Set the appropriate gate dial setting (refer to the Spreading Charts section as a starting point).

  4. Add material to the hopper (for example, 11.3 kg (25 lb) was added).

  5. Drive the spreader over the calibration course while applying the material.

  6. Empty the remaining material of the hopper into a clean bucket.

  7. Weigh the bucket containing the material and record the weight. Pour the contents back into the hopper and then weigh the empty bucket. Subtract these two amounts to determine the amount of material remaining in the hopper (for example, 9 kg (20 lb) remains.)

  8. Subtract the amount remaining in the hopper (step 7) from the amount originally added (step 4); the result is the amount applied to the course.

    Amount Applied

    11.3 kg (25 lb) – 9 kg (20 lb)=2.3 kg (5 lb)

    For this example, 2.3 kg (5 lb) was applied to 93 m2 (1,000 ft2).

  9. If necessary, adjust the rate dial to achieve the recommended amount to be applied and repeat the procedure. Once the correct application rate is achieved, repeat this procedure an additional time to verify the results.

    Note: Designate a new calibration course each time, so the turf is not damaged.

Spreader Pattern Adjustment

If the spread pattern is skewed or dispensing too light/heavy to one side (see Figure 25 and Figure 26), adjust the gate as follows:

g025543

Figure 25

  1. Heavy to left side
  2. Move ramp pattern to shaded position
  3. Heavy to right side

Note: Do not adjust the ramps to split product flow. Use only the front or rear ramp positions as shown.

To adjust when the material pattern rotate the spread pattern control knob:

  • Clockwise if heavy on left side.

  • Counterclockwise if heavy on right side.

Operating the Sprayer

The sprayer disperses liquid substances. Before using the sprayer make sure it has been properly cleaned before adding any chemicals. When using the sprayer, first fill the spray tank, then apply the solution to the work area, and finally clean the tank. It is important to complete all three of these steps 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.

Note: Clean your sprayer thoroughly after all applications.

Before Operating the Sprayer

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.

Make sure the sprayer has been calibrated before starting; refer to Spray Calibration/Tip Chart/Liquid Quantities.

Filling the Spray Tank

Important: Ensure that the chemicals you will be using are compatible for use with Viton® or fluorocarbon (see the manufacturer's label; it should indicate if it is not compatible). Using a chemical that is not compatible with Viton® or fluorocarbon 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.

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

  1. Stop the machine on a level surface, move motion control lever 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 needed as prescribed by the chemical manufacturer.

  3. Open the tank cap on the spray tank.

  4. Add 3/4 of the required water to the spray tank.

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

  5. Start the engine and place the throttle midway between the SLOW and FAST positions.

  6. Set the spray pump switch to the ON position.

    7. Spray pump switch

  7. Move the throttle to the FAST position.

    Note: The water in the tank will circulate.

  8. Before adding chemicals to the tanks, be sure:

    • the valving is set for the tank that is being used; refer to Spray Pump Valving.

    • the spray pressure control knob is all the way open (turn counterclockwise). This will increase circulation/agitation and help purge the system of air.

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

    Important: If 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 and secure tank cap.

    Note: Anytime the tank has been run dry, repeat steps 5 through 10. This will reduce the time required to purge the system of air.

Extending and Folding the Outer Spray Booms

The outer spray booms can be rotated forward to extend the boom or rearward to fold the boom.

    1. Overlap area
    2. Effective spray area

  • Watch for plugged nozzles.

  • Disengage spray control levers to stop the spray flow before stopping the motion of the sprayer. Once stopped, leave the motion control lever in neutral and keep the pump running.

  • Better results are obtained if the sprayer is moving when spray controls are turned 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.

Note: Make sure the machine has been calibrated properly before starting spray application

  1. Make sure the spray pump is on.

  2. Drive to the work area to be sprayed.

  3. Adjust the spray pressure to the appropriate setting.

  4. Turn on the appropriate spray control:

    The sprayer and spreader can be operated either together or individually (spray liquid and spread granular at the same time or separately). Regardless of the situation, make sure that the machine is running at full throttle.

    When finished spraying, turn off the spray control lever and the spray pump switch.

    The spray pump switch can be left on for tank agitation.

    To use the spray wand:

    Warning

  5. When finished spraying:

    • From the front spray nozzles:

      Turn the three section valves off.

    • From the spray wand:

      1. Release the trigger and its lock (if applicable).

      2. Turn the spray wand flow valve off

      3. Return the wand back to its holder.

Important: Contact an Authorized Service Dealer if the spreader-sprayer fails to operate properly.

Cleaning the Sprayer

Clean the spray system after each spraying session.

Important: 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.

To properly clean the spray system:

  • Use three separate rinses.

  • Use a minimum of 19 L (5 US gallons) for each rinse.

  • Use the cleaners and neutralizers as recommended by the chemical manufacturers.

  • Use pure clean water (no cleaners or neutralizers) for the last rinse.

Warning

Do not clean spray nozzles by mouth or blowing through them. Swallowing or inhaling chemicals could cause serious injury or death.

Replace all worn and damaged nozzles.

Make sure nozzles are installed correctly.

  1. Drive the machine to a designated cleaning area.

  2. Stop the spreader-sprayer on a level surface, leave the motion control lever in the neutral position, and turn off the engine. Engage the parking brake.

  3. Fill the tank with clean fresh water and close the cover.

  4. Start the engine.

  5. With the motion control lever in neutral position, engage the pump, and set the engine throttle to FAST.

  6. Set the three spray valves to ON.

  7. Allow the water in the tank to spray out through the nozzles.

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

  9. Set the spray valve to ON. Remove the wand from its holder and point it in a safe direction.

  10. Squeeze the spray wand trigger to release the pressure.

  11. Return the wand to its holder.

  12. Set the spray control levers and the wand lever to the OFF position, disengage the pump, and stop the engine.

  13. Clean the strainer located below the knee pad. Close both tank supply valves. When removing the canister, drain any unused chemical from the line and dispose of it according to local codes and the chemical manufacturer's instructions.

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

    g387234

To close the valve, pull the handle outward and rotate the handle counterclockwise until handle locks.

Spray Calibration/Tip Chart/Liquid Quantities

Note: Before using the sprayer for the first time, change nozzles, or as needed–calibrate the sprayer flow and speed.

Note: Refer to the chemical product label for application rate recommendations.

The lavender colored air injected tips come standard on the machine. These tips will apply liquid material at 1.24 L (0.34 US gallons) per 93 m2 (1,000 ft2) at 8 km/h (5 mph) and 276 kPa (40 psi). Each tip has a 276 kPa (40 psi) shut-off screen to prevent drip.

The machine is capable of using tips from 0.95 L (0.25 US gallons) to 3.8 L (1 US gallons) in size. See the chart below for the desired drop rate.

Note: This chart only applies if using air injected tips. Using other tips will require different calculations.

Tip ColorKM/HMPHkPapsiL/96 m2US gallons/ 1,000 ft2
Yellow85276400.95 L0.25 (1/4) US gallon
Lavender85276401.25 L0.33 (1/3) US gallon
Red85276401.9 L0.5 (1/2) US gallon
Brown85345502.84 L0.75 (3/4) US gallon
Grey64276403.79 L1 US gallon

Note: Please refer to the spray chart, located on the backside of the knee pad, for complete calibration.

To determine liquid quantities per tank, verify the tips installed on the machine (factory set is 1.25 L (0.33 US gallon) per 96 m2 (1,000 m2 through the Lavender tips).

For example, if the product calls for 32.5 to 44.3 ml (1.1 to 1.5 oz) per 96 m2 1,000 m2, use the median value of 38.4 ml (1.3 oz). The lavender tip is a 1.25 L (1/3 US gallon) tip, multiply by 3, and then multiply that number by the gallons added to the tank. If the tank is 113.5 L (30 US gallons) the equation would look like this:

1.3 X 3 X gallons needed.

1.3 median value X 3 X 30 gallons = 117 ounces used in 30 gallons of water.

After Operation

After Operation Safety

General Safety

  • Park machine on level ground, disengage drives, set parking brake, stop engine, and remove key. Wait for all moving parts to stop before leaving the operator’s position. Allow the machine to cool before servicing, adjusting, fueling, cleaning, or storing.

  • Clean grass, leaves, excessive grease or oil, and other debris from the muffler, drives, and engine area to help prevent fires.

Transporting the Machine

Note: Refer to the chemical warning product label(s) before transporting the machine and follow all local/state/federal requirements for transporting chemicals.

Note: Make sure the spreader hopper cover and the spray wand are secure before transporting.

Transporting the Machine

Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary lighting and marking as required by law. Thoroughly read all of the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.

To transport the machine:

  • Lock the brake and block the wheels.

  • Securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes. When securing the front of the machine, only use the tie down locations shown in Figure 41. If possible, both front and rear straps should be directed down and outward from the machine. Using non-designated locations may cause damage to the machine and/or attachment.

    g387256

    Figure 41

    1. Tie down location

    Warning

    Securing the machine on any upper frame location will cause the parking brake to not function properly, which could cause serious injury or death.

    Only use the front tie down locations on the lower frame to secure the machine.

  • Secure a trailer to the towing vehicle with safety chains.

Warning

Driving on the street or roadway without turn signals, lights, reflective markings, or a slow moving vehicle emblem is dangerous and can lead to accidents causing personal injury.

Do not drive machine on a public street or roadway.

Loading the Machine

Use extreme caution when loading machines on trailers or trucks. One full width ramp that is wide enough to extend beyond the rear tires is recommended instead of individual ramps for each side of the machine. A full width ramp provides a surface to walk on behind the machine. If it is not possible to use one full width ramp, use enough individual ramps to simulate a full width continuous ramp.

A steep ramp angle may cause components to get caught as the machine moves from ramp to trailer or truck. Steeper angles may also cause the machine to tip backward. If loading on or near a slope, position the trailer or truck so it is on the down side of the slope and the ramps extends up the slope. This will minimize the ramp angle. The trailer or truck should be as level as possible.

Important: Do not attempt to turn the machine while on the ramp, you may lose control and drive off the side.

Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp. Both maneuvers can cause the machine to tip backward.

Warning

Loading a machine on a trailer or truck increases the possibility of backward tip-over. Backward tip-over could cause serious injury or death.

  • Use extreme caution when operating a machine on a ramp.

  • Use only a single, full width ramp; do not use individual ramps for each side of the machine.

  • If individual ramps must be used, use enough ramps to create an unbroken ramp surface wider than the machine.

  • Avoid sudden acceleration while driving machine up a ramp to avoid tipping backward.

  • Avoid sudden deceleration while backing machine down a ramp to avoid tipping backward.

Maintenance

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

Maintenance Safety

  • Park machine on level ground. Disengage the spray or close the spreader gate, set the parking brake, stop engine and remove key or disconnect spark plug wire. Wait for all moving parts to stop before leaving the operator’s position. Allow the machine to cool before servicing, adjusting, fueling, unclogging, cleaning, or storing.

  • If you leave the key in the switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the switch before you perform any maintenance.

  • Never allow untrained personnel to service machine.

  • Disconnect battery or remove spark plug wire before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last.

  • Relieve the spray pressure from the system before servicing.

  • Empty the tank and/or hopper before tilting the machine for maintenance and before storing.

  • Keep all guards, shields, switches, and all safety devices in place and in proper working condition. Frequently check for worn or deteriorating components and replace them with genuine Toro parts when necessary.

    Warning

    Removal or modification of original equipment, parts and/or accessories may alter the warranty, controllability, and safety of the machine. Unauthorized modifications to the original equipment or failure to use original Toro parts could lead to serious injury or death. Unauthorized changes to the machine, engine, fuel or venting system, may violate applicable safety standards such as: ANSI, OSHA and NFPA and/or government regulations such as EPA and CARB.

    Warning

    Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid accidentally injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.

    • If equipped, make sure all hydraulic fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to hydraulic system.

    • Keep body and hands away from pinhole leaks or nozzles that eject high pressure hydraulic fluid.

    • Use cardboard or paper, not your hands, to find hydraulic leaks.

    • Safely relieve all pressure in the hydraulic system by placing the motion control levers in neutral and shutting off the engine before performing any work on the hydraulic system.

  • Do not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands.

  • Carefully release pressure from components with stored energy.

  • Keep your hands and feet away from moving parts or hot surfaces. If possible, do not make adjustments with the engine running.

  • Keep all parts in good working condition and all hardware tightened.

    Electrical System Maintenance

    Check Battery Charge

    Maintenance Service IntervalMaintenance Procedure
    Monthly
  • Check the battery charge.
    		•

    Allowing batteries to stand for an extended period of time without recharging them will result in reduced performance and service life. To preserve optimum battery performance and life, recharge batteries in storage when the open circuit voltage drops to 12.4 V.

    Note: To prevent damage due to freezing, battery should be fully charged before putting away for winter storage.

    Charge batteries in an open well ventilated area, away from spark and flames. Unplug charger before connecting or disconnecting from battery. Wear protective clothing and use insulated tools.

    Danger

    Charging or jump starting the battery may produce explosive gases. Battery gases can explode causing serious injury.

    • Keep sparks, flames, or cigarettes away from battery.

    • Ventilate when charging or using battery in an enclosed space.

    • Make sure venting path of battery is always open once battery is filled with acid.

    • Always shield eyes and face from battery.

    Danger

    Battery electrolyte contains sulfuric acid, which is poisonous and can cause severe burns. Swallowing electrolyte can be fatal or if it touches skin can cause severe burns.

    • Wear safety glasses to shield eyes, and rubber gloves to protect skin and clothing when handling electrolyte.

    • Do not swallow electrolyte.

    • In the event of an accident, flush with water and call a doctor immediately.

    Caution

    If the ignition is in the ON position there is potential for sparks and engagement of components. Sparks could cause an explosion or moving parts could accidentally engage causing personal injury.

    Be sure ignition switch is in the OFF position before charging the battery.

    1. Check the voltage of the battery with a digital voltmeter or with the message display. If the voltage is less than 12.4 V, the battery may need to be charged.

      Important: In order to prevent damage to the battery, use an automatic 12 volt smart charger approved for use with AGM type batteries with an output of 3.5 amps or less. Toro recommends the use of battery charger P/N 135-7024. Make sure the negative battery cable is disconnected before charging and that the charger is set to the correct mode for 12 V AGM batteries.

    2. Connect the negative battery cable.

      Note: If the positive cable is also disconnected, connect the positive (red) cable to the positive battery terminal first, then the negative (black) cable to the negative battery terminal. Slip insulator boot over the positive terminal.

      Note: If time does not permit charging the battery, or if charging equipment is not available, connect the negative battery cables and run the vehicle continuously for 20 to 30 minutes to sufficiently charge the battery.

    Recommended Jump Starting Procedure

    1. Check the weak battery for terminal corrosion (white, green, or blue “snow”), it must be cleaned off prior to jump starting. Clean and tighten connections as necessary.

      Caution

      Corrosion or loose connections can cause unwanted electrical voltage spikes at anytime during the jump starting procedure.

      Do not attempt to jump start with loose or corroded battery terminals or damage to the engine may occur.

      Danger

      Jump starting a weak battery that is cracked, frozen, has low electrolyte level, or an open/shorted battery cell, can cause an explosion resulting in serious personal injury.

      Do not jump start a weak battery if these conditions exist.

    2. Make sure the booster is a good and fully charged lead acid battery at 12.6 V or greater. Use properly sized jumper cables (4 to 6 AWG) with short lengths to reduce voltage drop between systems. Make sure the cables are color coded or labeled for the correct polarity.

      Caution

      Connecting the jumper cables incorrectly (wrong polarity) can immediately damage the electrical system.

      Be certain of battery terminal polarity and jumper cable polarity when hooking up batteries.

      Note: The following instructions are adapted from the SAE J1494 Rev. Dec. 2001 – Battery Booster Cables – Surface Vehicle Recommended Practice (SAE – Society of Automotive Engineers).

      Warning

      Batteries contain acid and produce explosive gases.

      • Shield the eyes and face from the batteries at all times.

      • Do not lean over the batteries.

      Note: Be sure the vent caps are tight and level. Place a damp cloth, if available, over any vent caps on both batteries. Be sure the vehicles do not touch and that both electrical systems are off and at the same rated system voltage. These instructions are for negative ground systems only.

    3. Connect the positive (+) cable to the positive (+) terminal of the discharged battery that is wired to the starter or solenoid as shown in .

    Waste Disposal

    Chemical Disposal

    Improper chemical disposal can pollute the environment and cause health issues.

    Follow the disposal directions on the chemical manufacturer’s label. Dispose of chemicals and containers in accordance to local/state/federal laws.

    Motor Oil Disposal

    Engine oil and hydraulic oil are both pollutants to the environment. Dispose of used oil at a certified recycling center or according to your state and local regulations.

    Battery Disposal

    Danger

    Battery electrolyte contains sulfuric acid, which is poisonous and can cause severe burns. Swallowing electrolyte can be fatal or if it touches skin can cause severe burns.

    • Wear safety glasses to shield eyes, and rubber gloves to protect skin and clothing when handling electrolyte.

    • Do not swallow electrolyte.

    • In the event of an accident, flush with water and call a doctor immediately.

    Federal law states that batteries should not be placed in the garbage. Management and disposal practices must be within relevant federal, state, or local laws.

    If a battery is being replaced or if the unit containing the battery is no longer operating and is being scrapped, take the battery to a local certified recycling center. If no local recycling is available return the battery to any certified battery reseller.

    Storage

    Extended or Winter Storage

    To help protect the pumps from freezing temperatures make sure the unit is free of all caustic chemicals and residue.

    Spreader Cleaning
