Toro Spreader Sprayer Safety

The following list contains safety information specific to Toro products and other safety information you must know.

General Operation

  • Check carefully for overhead clearances (i.e. branches, doorways, electrical wires, etc.) before operating under any objects, and do not contact them.

  • Use caution when you are riding on the platform and driving the machine over curbs, rocks, roots, or other obstructions.

  • Do not jerk the controls; use a steady motion.

  • Do not carry passengers.

  • Do not carry equipment on the machine.

Sprayer and Spreader Operation

Warning

The spray wand traps liquids under high pressure, even when engine is off. High-pressure spray 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 attach hoses or other components to the end of the spray-wand nozzle.

  • Do not attempt to disconnect the spray wand from the unit 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.

  • Do not touch the impeller for the spreader while the impeller is rotating.

  • Stop spreading/spraying when making tight turns to minimize an 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.

  • 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 unit to tip over.

  • Safely relieve pressure from spray wand every time engine is shut off.

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

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

Slope Operation

Use extreme caution when spreading or spraying chemicals and/or turning on slopes as loss of traction and/or tip-over could occur. The operator is responsible for safe operation on slopes.

  • Remove or mark obstacles such as rocks, tree limbs, etc., from the area on which you are spreading or spraying chemicals.

  • Watch for holes, ruts or bumps.

    Note: Tall grass can hide obstacles.

  • Use caution near drop-offs, ditches, or embankments.

    Note: The machine could suddenly turn over if a wheel goes over the edge of a cliff or ditch, or if an edge caves in.

  • Be aware that operating on wet grass, across steep 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.

  • Do not spread or spray chemicals on slopes greater than 15 degrees; refer to Figure 3 to determine the approximate slope angle of the work area.

  • Avoid sudden starts and stops when spreading or spraying chemicals uphill because the machine may tip backward.

    Note: The machine is more stable driving uphill.

  • Keep all movement on slopes slow and gradual.

  • Do not make sudden changes in speed or direction.

  • Follow the manufacturer’s recommendations for wheel weights or counter weights to improve stability.

  • Use extra care with attachments.

    Note: Use of attachments can change the stability of the machine.

Service

  • To ensure safe, optimal performance of the machine, use only genuine Toro replacement parts. Replacement parts made by other manufacturers could be dangerous, and such use could void the product warranty.

  • Never remove or tamper with safety devices. Check their proper operation regularly. Never do anything to interfere with the intended function of a safety device or to reduce the protection provided by a safety device.

  • Check brake operation frequently. Adjust and service as required.

Checking the Engine-Oil Level

Maintenance Service IntervalMaintenance Procedure
Before each use or daily
  • Check the engine-oil level.
    		•

    Oil Type: Detergent oil (API service SJ or higher)

    Oil viscosity: Refer to the table below.

    g027233

    Figure 16

    Important: Do not operate the engine with the oil level below the Low (or Add) mark on the dipstick, or over the Full mark.

    1. Move the machine to a level surface.

    2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position

    3. Allow the engine to cool.

    4. Remove the dipstick from the engine and wipe the dipstick with a clean rag (Figure 17).

      g033503g027234

      Figure 17

      1. Dipstick
      2. Maximum oil level
      3. Minimum oil level

    5. Insert the dipstick from the engine as shown in Figure 17.

      Note: Do not thread the dipstick into the filler neck when checking the engine oil level.

    6. Remove the dipstick from the filler neck and look at the oil level in the dipstick (Figure 17).

      Note: The engine oil level must cover between the hatch marked areas on the dipstick (Figure 17).

    7. If the oil level is low, wipe off the area around the filler neck and add the specified oil until the oil level is between the hatch marked areas on the dipstick.

      Important: Do not overfill the engine with oil.

    8. Hand tighten the dipstick into the filler neck (Figure 17).

    Adding Fuel

    Fuel tank capacity: 6.1 L (1.6 US gallons)

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

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

    • Do not use gasoline containing methanol.

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

    • Do not add oil to the fuel.

    Danger

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

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

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

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

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

    • Never buy more than a 30-day supply of gasoline.

    Danger

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

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

    • Do not fill the 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 equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

    • If this is not possible, then refuel the 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.

    Warning

    Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.

    • Avoid prolonged breathing of vapors.

    • Keep face away from nozzle and gas tank or conditioner bottle opening.

    • Avoid contact with skin; wash off spillage with soap and water.

    Using Stabilizer/Conditioner

    Use a fuel stabilizer/conditioner in the machine to provide the following benefits:

    • Keeps fuel fresh during storage of 90 days or less. For longer storage it is recommended that the fuel tank be drained.

    • Cleans the engine while it runs

    • Eliminates gum-like varnish buildup in the fuel system, which causes hard starting

      Important: Do not use fuel additives containing methanol or ethanol.

      Add the correct amount of gas stabilizer/conditioner to the gas.

      Note: A fuel stabilizer/conditioner is most effective when mixed with fresh fuel. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

    Fueling the Machine

    Note: Refueling the engine is difficult when using a larger refueling container such as a container with a 19 L (5 US gal) capacity.To make fueling the machine easier use the following equipment:

    • a fuel container with approximately a 4 to 8 L (1 to 2 US gal) capacity

    • a funnel

    1. Clean around the fuel tank cap.

    2. Remove the cap from the tank.

    3. Fill the fuel tank with unleaded gasoline to within 6 to 13 mm (1/4 to 1/2 inch) from the top of the tank. Do not fill into the filler neck.

      Important: Do not fill the tank more than 6 mm (1/4 inch) from the top of the tank because the gasoline must have room to expand.

    4. Install the fuel-tank cap and wipe up any spilled fuel.

    Operating the Spreader

    Caution

    Chemicals are hazardous and can cause personal injury.

    • Read the chemical manufacture’s directions on the label before handling the chemicals; 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 eye protection, gloves, and any other protective equipment recommended by the chemical manufacturer.

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

    Note: When you use your spreader, thoroughly clean it at the end of the day.

    Before Operating the Spreader

    Before you start using the spreader, ensure that the spreader has been calibrated for the material that you will disperse; refer to Calibrating the Spreader.

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

    Calibrating the Spreader

    Calibrate the spreader each time a new material is used. The spreader can broadcast material in a pattern 1.5 to 6.7 m (5 to 22 ft) wide depending on the material particle size, volume/density, and rate of travel, and wind conditions.

    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. Allow ample driving distance before the area where the collection pans are located to ensure that the machine is traveling at the desired speed (for spreading) before the machine reaches the collection 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 adequate room for the drive tires of the machine to pass around the center pan.

    3. Place the remaining pans in a straight line as shown in Figure 22 or Figure 23.

      • For larger granule materials:

        Space six additional pans, on each side, 12 inches (30 cm) apart (Figure 22).

        g027328

        6. Graduated measuring cylinder

    4. Set the drop rate cam to the recommended application rate; refer toSpreading Charts to determine the appropriate drop-rate cam setting.

    5. Fill the hopper approximately half-full with the desired material; refer to Filling the Spreader Hopper.

    6. Set the spreader pattern control to the middle of its travel; refer to Adjusting the Spreader Pattern.

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

    8. Pull the wide distribution granular gate control to the open position and drive the spreader, at the appropriate speed, over the center pan.

      Note: Repeat broadcasting over the test site several times, moving in the same direction each time, until enough material is dispensed to the collection pan to fill a graduated cylinder half full

    9. Label each graduated measuring cylinder to correspond with the distribution pans (i.e. ...L2, L1, Center, R1, R2...); refer to Figure 22 and Figure 23.

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

    11. 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.

    12. To adjust the spreader pattern, refer to the Adjusting the Spreader Pattern.

    13. Repeat steps 5 through 12 until an 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 6 to 8 m (20 to 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 1/2 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 area and amount of material that you are applying to the job site.

    2. Determine the calibration course length as follows:

      1. Initially, use the recommended rate indicated in theSpreading Charts section or the rate recommended on the product manufacturer’s label as a guide to help determine the amount of material that you would spread over a 93 m2 (1,000 ft2) area.

      2. Determine a course length by dividing 93 m2 (1,000 ft2) by the effective spread width.

        Note: For example, if the effective width is 1.8 meters (6 feet), 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 51m (167 ft).

      4. Measure and visibly mark the course length. Ensure that you allow enough distance before the starting marker so that the spreader moving forward at full speed when crossing the first mark of the course.

    3. Set the appropriate drop-rate cam setting; refer to the Spreading Charts as a starting point.

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

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

    6. Empty the remaining material of the hopper into a clean bucket; refer to Emptying the Hopper.

    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) of material is remained in the hopper after applying the material to the test course.

    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) of material was applied to the 93 m2 (1,000 ft2) test course.

    9. If necessary, adjust the drop-rate cam to achieve the recommended application rate. Once the correct application rate is achieved, repeat this procedure an additional time to verify your results.

      Important: Designate a new calibration course each time, so the turf is not damaged by excessive application of material.

    Using the Spreader

    Filling the Spreader Hopper

    Maximum hopper weight capacity: 79 kg (175 lb)

    1. Drive the machine to the work site.

    2. Move the machine to a level surface, move motion-control lever to the NEUTRAL position, shut off the engine, and set the parking brake.

    3. Ensure that the wide-distribution impeller-gate lever is in the fully forward (closed) position; refer to Wide-distribution Impeller-Gate Lever.

    4. Use the Spreading Charts to determine the setting for the drop-rate cam (Figure 24).

      Note: If the setting is not listed for the type of material that you are using, set the cam to the setting with a lower value then adjust as needed.

    Adjusting the Spreader Pattern

    If the spreader is casting material in a unequal side-to side—too light/heavy to one side—(see Figure 29 and Figure 30), adjust the spreader-pattern control as follows:

    g025543

    Figure 29

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

    Note: Do not adjust the ramps that split the product flow. Adjust only the front or rear ramp positions.

    1. Unlock the spreader-pattern control by turning the handle counterclockwise 90 degrees as shown in 2 of Figure 30.

      g027035

      Figure 30

      1. Spreader-pattern control
      2. Rotate counterclockwise to unlock
      3. Start notch if pattern is heavy to left side
      4. Start notch if pattern is heavy to right side
      5. Rotate clockwise to lock

    2. Adjust the spreader pattern as follows:

      • If the material is broadcast too heavy at the left side of the machine, pull the spreader-pattern control up slightly; refer to 3 of Figure 30.

      • If the material is broadcast too heavy at the right side of the machine, push the spreader-pattern control down slightly; refer to 4 of Figure 30.

    3. Lock the spreader-pattern control by turning the handle clockwise 90 degrees; refer to 5 of Figure 30.

    Using the Deflector Gate

    Use the deflector-gate control to temporarily stop or deflect granular material away from sidewalks, parking lots, patios, or anywhere the granular chemicals are not desired.

    Note: The deflector gate changes the discharged of materials from the left side of the spreader only.

    Push the knob for the deflector-gate control down to lower the deflector and temporarily deflect the granular material.

    Pull the knob up to raise the deflector for normal casting of materials at the left side of the machine.

    • To ensure uniform application, broadcast the material in an overlapping pattern as shown in Figure 32. The highest amount of material will dispense from the front of the hopper and less material from each side. You can adjust the distribution pattern to achieve the desired results.

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

    Note: Ensure that you calibrate the spreader before you start using the spreader.

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

    2. Set the impeller-speed control to appropriate broadcast rate and then press the impeller On/Off switch to the ON position (Figure 33).

    5. Evaluate the spread pattern.

      Note: If adjustments to the spreading pattern are needed, refer to Calibrating the Spreader.

    6. When you are finished spreading, close the wide-distribution impeller-gate lever.

      Note: Only the wide-distribution impeller-gate lever will close the impeller gate. Pushing the wide-distribution impeller-gate lever forward will also reset the narrow-distribution impeller-gate lever to the forward position.

    7. Clean the hopper after each spreading session; refer to Cleaning and Lubricating the Spreader.

      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 and Lubricating the Spreader

    Maintenance Service IntervalMaintenance Procedure
    After each use
  • Clean and lubricate the spreader.
    		•

    1. Drive the machine to a designated cleaning area with a level surface.

    2. Move the motion-control lever in the NEUTRAL position, shut off the engine, and set the parking brake.

    3. Empty the hopper; refer to steps 2 through 6 in Emptying the Hopper.

    4. Using a hose to 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 can force residual-corrosive materials into spreader-spreader components.

    5. Tilt the screen at the bottom of the hopper forward to clean the bottom components of hopper (Figure 36).

      g033504

    Operating the Sprayer

    Caution

    Chemicals are hazardous and can cause personal injury.

    • Read the chemical manufacture’s directions on the label before handling the chemicals; 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 eye protection, gloves, and any other protective equipment recommended by the chemical manufacturer.

    Use the sprayer to disperse liquid herbicides, pesticides, fertilizers, and other substances. Before using the sprayer ensure that you have cleaned the tank, plumbing, and nozzles before adding any chemicals. When you use the sprayer, you first fill the spray tank, then apply the chemical solution to the work site, and then when you are finished spraying, 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 the night before and then spray in the morning. This could lead to separation of the chemicals and possible cause damage to components of the sprayer.

    Calibrating the Sprayer

    Note: Before you use the sprayer for the first time or change the nozzles or when the sprayer is out of adjustment—calibrate the sprayer for ground speed and flow rate.

    Note: The left and right sprayer boom nozzles are wide pattern (white)nozzles and the center nozzle is narrow pattern (red) nozzle.

    Note: Refer to the chemical product label for output recommendations.

    The method to calibrate the sprayer flow involves driving a preset distance, recording the time, and then measuring the amount of liquid applied during that time.

    Calculating the Ground Speed

    Operator supplied equipment: Stop watch capable of measuring ± 1/10 second.

    1. Measure and visibly mark a course length to use to calculate your the average ground speed.

      Record your course length here .

      Note: Allow ample distance ahead of the starting marker to ensure the machine is at full ground speed when you cross the first marker of the course.

      Note: Example: the course length equals 45.7 m (150 ft).

    2. Add clean water into the spray tank 1/2 full; refer to Filling the Spray Tank.

    3. Drive the sprayer to an area far enough away from the course so that the machine will be traveling at the desired ground speed for spraying before the it reaches the first marker.

    4. Use a stop watch to measure the time (in seconds) that it takes the machine to travel the marked course (45.7 m (150 ft) in this example) while maintaining the desired ground speed.

      Note: Record your course time in the course time worksheet.

    Determining Application Rate

    Use the example results of the calculated speed, spray width, and nozzle capacity to determine the application rate.

    Note: The application rate may also be determined by using the Nozzle Flow Rate Chart, along with the chemical manufacturer’s label of recommendation.

    The examples below are based on the following information:

    • Average ground speed = 8.4 kph (5.2 mph)

    • Spray width = 2.7 m (108 inches)

    • Number of nozzles = 2

    • Nozzle capacity = 3.0 L/min (.79 gpm)

    Note: The numbers 6 and 600 are constants used in the formulas shown below.

    Using the Sprayer

    Before Operating the Sprayer

    Some chemicals are more aggressive than others and each chemical interacts differently with various materials. Some consistencies of sprayer chemicals (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.

    Ensure that the sprayer is calibrated before you start using the machine; refer to Calibrating the Sprayer.

    Filling the Spray Tank

    Important: Ensure that the chemicals that you are using in the sprayer are compatible for use with O-rings and seals made from fluoroelastomer material (refer to the chemical manufacturer's label; it should indicate if it is not compatible). If you use a chemical that is not compatible with fluoroelastomer material, the O-rings and seals in the sprayer can degrade and leak.

    Important: Before applying chemicals to the job site, verify that you have set the proper application rate prior to filling the tank.

    1. Move the machine to a level surface, move motion-control lever to the NEUTRAL position, shut off the engine, and set the parking brake.

    2. Ensure that the handle for the drain valve for the tank rotated 90 degrees counterclockwise to the is closed position (Figure 41).

    Transporting the Machine

    Machine weight: 227 kg (500 lb)—both sprayer tank and hopper empty; 389 kg (857 lb)—both sprayer tank and hopper full

    Caution

    This machine does not have proper turn signals, lights, reflective markings, or a slow moving vehicle emblem. Driving on a street or roadway without such equipment is dangerous and can lead to accidents causing personal injury. Driving on a street or roadway without such equipment may also be a violation of State laws and the operator may be subject to traffic tickets and/or fines.

    Do not drive a machine on a public street or roadway.

    Loading the Machine onto a Transport Vehicle

    Warning

    Loading the machine onto a trailer or truck increases the possibility of backward tip-over, and 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.

    • Do not exceed a 15-degree angle between ramp and ground, or between a ramp, a trailer, or a truck.

    • 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.

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

    • Use extreme caution when loading units onto trailers or trucks.

    • Use 1 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 (Figure 54). The platform, when down and locked into position, must extend back between the rear wheels and serves as a stop for tipping backward. Having a full-width ramp provides a surface for the platform to contact if the machine starts to tip backward. With the platform up, a full-width ramp provides a surface to walk on behind the machine.

    • The ramp should be long enough so that the angles do not exceed 15 degrees (Figure 54). A steeper angle may cause the chassis to get caught as the machine moves from ramp to trailer or truck. A steeper angle 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 ramp extends up the slope. This will minimize the ramp angle. The trailer or truck should be as level as possible.

      g000951

      Figure 54

      1. Trailer
      2. Full-width ramp
      3. Not greater than 15 degrees
      4. Full-width ramp (side view)

    • The operator should determine if it is best to have the platform up or down when loading, depending on conditions. If it is not possible to use one full-width ramp, use enough individual ramps to simulate a full-width, continuous ramp.

    • 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.

    Transporting the Machine

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

    Note: Ensure that the spreader-hopper cover and the spray wand are secure before transporting.
