Before Operation Safety

General Safety

  • Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Use only accessories and attachments approved by Toro.

  • Inspect the area where you will use the equipment, and remove all rocks, toys, sticks, wires, bones, and other foreign objects that may be contaminated by chemicals and/or affect the stability of the machine.

  • Wear appropriate clothing, including safety glasses, substantial slip-resistant footwear, and hearing protection. Tie back long hair and avoid loose clothing or jewelry that may get tangled in moving parts.

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

  • Do not fill, calibrate, or clean the machine while 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 the machine if it is leaking or damaged.

  • Ensure that the operator platform is clean and free from chemical residue and debris buildup.

  • Check that the operator-presence controls (if applicable), safety switches, and shields are attached and functioning properly. Do not operate the machine unless they are functioning properly. Frequently check for worn or deteriorating components and replace them with the manufacturer’s recommended parts when necessary.

Chemical Safety

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 Safety Data Sheets (SDS) 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 the following:

    – 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

  • If you are using more than 1 chemical, read the information about each chemical. Refuse to operate or work on the spreader-sprayer if this information is not available.

  • Before working on a spreader-sprayer system, ensure that the system has been triple rinsed and neutralized according to the recommendations of the chemical manufacturer(s) and that all 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.

  • Obtain proper training before using or handling chemicals.

  • Use the correct chemical for the job.

  • Follow the chemical manufacturer's instructions for the safe application of the chemical and do not exceed the recommended system application pressure.

  • Handle chemicals in a well-ventilated area.

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

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

  • Do not clean spray nozzles by blowing through them or placing them in your mouth.

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

  • Keep chemicals in their original packages and in a safe location.

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

  • Chemicals and fumes are dangerous; never enter the tank or hopper, and do not place your head over or in the opening.

  • Follow all local, state, and federal requirements for spreading and spraying chemicals.

Fuel Safety

Use extreme care when handling fuel.

In certain conditions gasoline is extremely flammable and its 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. Wipe up any gasoline that spills.

  • Never refill the fuel tank or drain the machine indoors or inside an enclosed trailer.

  • Do not fill the fuel tank completely full. Fill the fuel tank to the bottom of the filler neck. The empty space in the tank allows the gasoline to expand.

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

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

  • 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.

  • If you spill fuel, do not attempt to start the engine. Move away from the area of the spill and avoid creating any source of ignition until the fuel vapors have dissipated.

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

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

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

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

    • When practical, remove 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 gasoline-dispenser nozzle.

    • If you must use a gasoline-dispenser nozzle, 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.

  • Gasoline is harmful or fatal if swallowed. Long-term exposure to vapors has caused cancer in laboratory animals. Failure to use caution may cause serious injury or illness.

    • Avoid prolonged breathing of vapors.

    • Keep your face away from the nozzle and gasoline tank or container opening.

    • Keep gasoline away from your eyes and skin.

    • Never siphon gasoline by mouth.

  • To help prevent fires, do the following:

    • Keep the engine and the engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris that 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 near a flame or any enclosed area where open pilot lights or heat appliances are present.

Fuel Specification

Petroleum fuelUse unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).
Ethanol blended fuelUse an 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.
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.

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.

Using Stabilizer/Conditioner

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

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

Add the correct amount of fuel stabilizer/conditioner to the gasoline.

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

Filling the Fuel Tank

Fuel tank capacity: 22.7 L (5 US gallons)

  1. Park the machine on a level surface and shut off the engine.

  2. Allow the engine to cool.

  3. Clean around the fuel-tank cap and remove it (Figure 15).

    g311556

    Figure 15

  4. Fill the tank with fuel (Figure 15) to the bottom of the filler neck. Do not fill into the filler neck of the tank.

    Important: Do not fill the tank more than the bottom of the filler neck because the fuel needs room to expand.

  5. Install the fuel-tank cap securely.

  6. Wipe up any spilled fuel.

During Operation

During Operation Safety

General Safety

Use your full attention when operating the machine. Do not engage in any activity that causes distractions; otherwise, injury or property damage may occur.

  • Running the engine will cause engine parts, especially the muffler, to become extremely hot. Severe burns can occur on contact, and debris, such as leaves, grass, and brush, can catch fire.

    • Allow engine parts, especially the muffler, to cool before touching them.

    • Remove accumulated debris from the muffler and engine area.

  • Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you. Do not run the engine indoors or in a small, confined area where carbon monoxide fumes can collect.

  • 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.

    • The owner/user can prevent and is responsible for accidents that may cause personal injury or property damage.

    • This machine was designed for 1 operator only. Do not carry passengers and keep all others away from machine during operation.

    • Do not operate the machine under the influence of alcohol or drugs.

    • Operate only in daylight or good artificial light.

    • Do not operate the machine when there is the risk of lightning.

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

    • 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 or cause you to lose your balance or footing.

    • Do not operate the machine with damaged guards, shields, or covers. Always have safety shields, guards, switches and other devices in place and working properly.

    • Keep clear of the discharge area at all times.

    • Keep your hands and feet away from moving parts. If possible, Do not make any adjustments while engine is running.

  • Your hands, feet, hair, clothing, or accessories can become entangled in rotating parts and cause serious injury.

    • Do not operate the machine without guards, shields, and safety devices in place and working properly.

    • Keep your hands, feet, hair, jewelry, or clothing away from rotating parts.

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

  • Be alert, slow down, and use caution when making turns. Look behind you and to the side before changing directions. Do not spread or spray in reverse unless it is absolutely necessary.

  • Stop spreading or spraying while 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.

  • Do not change the engine governor setting or overspeed the engine.

  • Ensure that all drives are in neutral and engage the parking brake before starting the engine.

  • Park the machine on level ground. Shut off the engine, wait for all moving parts to stop, remove key, and engage the parking brake before doing the following:

    • Checking, cleaning, or working on the machine

    • Clearing blockages

    • Leaving the machine; do not leave a running machine unattended.

  • Shut off the engine, wait for all moving parts to stop, and engage parking brake before refueling.

  • Tragic accidents can occur if you are not alert to the presence of children. Children are often attracted to the machine and the spreader-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.

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

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

    • Never allow children to operate the machine.

    • Do not carry children, even if the machine is not in use. Children could fall off and be seriously injured or interfere with the safe operation of the machine. Children wanting a ride could appear in the working area without warning and be run over or backed over by the machine.

  • Reduce the weight of the load when operating the machine 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.

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

  • Reduce the speed when operating on rough terrain or near curbs.

  • Safely relieve liquid from the spray wand every time you shut off the engine.

  • The spray wand traps liquids under high pressure, even when engine is not running. High-pressure spray discharge could cause serious injury or death.

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

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

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

    • Do not keep the spray wand in the locked-open position after you complete the job.

    • When draining or relieving the system, Do not allow anyone to stand in front of the 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. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution.

  • Review the slope instructions listed below for operating the machine on slopes and to determine whether you can operate the machine in the conditions on that day and at that job site. Changes in the terrain can result in a change in slope operation for the machine.

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

  • Identify hazards at the base of the slope. Determine if the slope is safe for machine operation, including surveying the site. Always use common sense and good judgment when performing this survey.

  • Avoid starting, stopping, or turning the machine on slopes. Travel up and down on slopes. Avoid making sudden changes in speed or direction. If you must turn the machine, turn it slowly and gradually downhill, if possible. Use care when reversing the machine.

  • Do not operate a machine when you are uncertain about the traction, steering, or stability.

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

  • Be aware that operating the machine on wet surfaces, across slopes, or downhill may cause the machine to lose traction. Loss of traction to the wheels may result in sliding and a loss of braking and steering.

  • Use extreme caution when operating the machine near drop-offs, ditches, embankments, water hazards, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in. Establish a safety area between the machine and any hazard.

    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.

  • Use extra care while operating the machine with attachments; they can affect the stability of the machine.

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

  • Always keep the transmission in gear (if applicable) when you drive the machine down a slope.

  • Do not park the machine on an incline.

  • The weight of the material in the tank can change the handling of the machine. To avoid loss of control and personal injury, follow these guidelines:

    • 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.

    • Liquid loads shift, especially while turning, going up or down slopes, suddenly changing speeds, or while driving over rough surfaces. Shifting loads can cause the machine to tip over.

Before Operating the Spreader

Before you start using the spreader, calibrate the spreader for the material that you will disperse; refer to Calibrating the Spreader.

Important: Prior to filling the hopper, verify that you have set the proper spreader-application rate.

Calibrating the Spreader

Calibrate the spreader each time you change granular materials. The spreader broadcasts material in a pattern 1 to 7.6 m (3 to 25 ft) wide depending on the material particle size, volume/density, impeller-motor speed, rate of travel, and wind conditions.

Use the Spreading Charts along with information from Determining the Distribution Pattern, Determining the Effective Spreading Width, and Calculating the Application Rate when calibrating the spreader.

Preparing the Test Site and Machine

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

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

  1. 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.

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

    • For larger granule materials:

      Space 6 additional pans, on each side, 12 inches (30 cm) apart (Figure 22).

      g027328

      6. Graduated measuring cylinder

  3. Move the machine far enough away from the test area (where the collection pans are located) to ensure that the machine travels at the desired spreading speed before reaching the site.

  4. Determine the application rate and the related drop-rate cam setting; refer to Spreading Charts.

  5. Rotate the drop rate cam (Figure 24) to the cam setting you determined in step 4.

    g259776

    Figure 24

    1. Drop rate cam

  6. Ensure that the hopper-door control is in the close position, and fill the hopper approximately half-full with the desired material; refer to Hopper Controls.

  7. Pull the deflector control handle and lock it; refer to Adjusting the Deflector Control.

Determining the Distribution Pattern

  1. Set the diffuser control to the middle of its travel and lock it; refer to Adjusting the Diffuser Control.

  2. Adjust the impeller speed control to set the broadcast pattern width; refer to Adjusting the Impeller-Speed Control.

  3. Drive the machine toward the test site at the appropriate speed.

  4. As you approach the center pan, pull the wide distribution granular gate control to the open position, and drive over the center pan.

  5. Close the gate control, move motion-control lever to the NEUTRAL position, shut off the engine, wait for all moving parts to stop, remove key, and engage parking brake.

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

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

    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 half fill a graduated cylinder.

  8. 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.

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

  10. Fill the hopper half-full of the desired material and repeat steps 1 through 9 until you achieve a uniform pattern.

Determining the Effective Spreading Width

Use the effective width to determine the uniform distribution of the granular material.

Note: The spreading width range is 1 to 8 m (3 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 2 graduated cylinder, one each side of center, that contains 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 the distance between left pan, across the center pan, to the outer edge of the right pan, and record the measurement.

    Record the effective spreading width here: .

Preparing the Calibration Course for Calculating the Application Rate

  1. Determine a course length by dividing 93 m2 (1,000 ft2) by the effective spread width that you determined in Determining the Effective Spreading Width; use the course length formula. Record the course length here: .

    Calibration Course Length Formula

    Formula93 m2 (1,000 ft2) / Effective width measurement=Calibration course length
        
    Example93 m2 (1,000 ft2) / 1.8 m (6 ft)=51 m (167 ft)

    Note: In this example the effective width measures 1.8 m (6 ft).

  2. 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.

Calculating the Application Rate

  1. Determine the area and amount of material that you are applying to the job site and record those amounts in the area and materials worksheet.

    Record the job site area here: .

    Record the amount of job site material here: .

  2. Initially, use the recommended application rate indicated in theSpreading Charts section or use the rate recommended listed 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.

    Note: In this example the calibration course is 1.8 m (6 ft) by 51m (167 ft).

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

  4. Add material to the hopper.

    Note: In this example we added 11.3 kg (25 lb) 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.

  7. Weigh the bucket containing the material and record the weight. Pour the contents back into the hopper and then weigh the empty bucket. Calculate the remaining material weight using the remaining material weight formula. Record the remaining material weight here: .

    Remaining Material Weight Formula

    Formula(Remaining material and bucket weight) - (Bucket weight)=Remaining material weight
        
    Example10 kg (22 lb) - 1 kg (2 lb)=9 kg (20 lb)

    Note: In this example, 9 kg (20 lb) of material remain in the hopper after applying the material to the test course.

  8. Calculate applies material weigh using the applied material formula that follows. Record the applied material weight here: .

    Applied Material Weight Formula

    Formula(Original material weight) - (Remaining material weight)=Applied material weight
        
    Example11.3 kg (25 lb) - 9 kg (20 lb)=2.3 kg (5 lb)
     3

    Note: This calculation means that at the selected motor-rotation speed, 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 you achieve the correct application rate, repeat this procedure an additional time to verify your results.

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

Filling the Spreader Hopper

Maximum hopper weight capacity: 100 kg (220 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, wait for all moving parts to stop, remove key, and engage parking brake.

  3. Ensure that the hopper-door control is in the fully forward (closed) position; refer to Adjusting the Hopper-Door Control.

  4. Use the Spreading Charts to determine the setting for the drop-rate cam (Figure 25).

    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.

    g312531

    Figure 25

    1. Cover
    2. Hopper
    3. Drop-rate cam

  5. Remove the cover from the hopper, add the material that you are spreading, and install the cover onto the hopper (Figure 25).

    Note: Do not overload the hopper; the maximum weight capacity of the hopper is 100 kg (220 lb).

    Note: You may place extra bags of granular material in the cargo boxes behind the spray tanks.

  5. Evaluate the spread pattern.

    Note: If you need to adjustment the spreading pattern, refer to Adjusting the Impeller-Speed Control, Calibrating the Spreader, and Adjusting the Spreader Pattern.

  6. When you are finished spreading, close the hopper-door control.

  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.

Spreading Tips

Important: Ensure that you calibrate the spreader before you start using it.

  • To ensure uniform application, broadcast pellet or granular material in an overlapping pattern.

    Note: 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.

Operating the Sprayer

Caution

Chemicals are hazardous and can cause personal injury.

  • Read the chemical manufacturer’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 3 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.

Important: When you use your sprayer, thoroughly clean it at the end of the day.

Sprayer Nozzle Application Rate

The machine is factory equipped with lavender colored nozzle tips that have an application rate of 1.3 L (0.34 US gallon) per 93 m2 (1,000 ft2) when the sprayer pressure is 2.8 bar (40 psi), and the machine is driven 8 kph (5 mph).

  • Use to the nozzle application rate chart that follows when selecting nozzles and spraying with the machine.

  • Refer to the spreader/sprayer chart affixed to the back of the knee pad for quick reference calibration information in the field.

  • Your machine supports application rates between 0.95 L per 93 m2 (0.25 US gallon per 1,000 ft2) through 3.8 L per 93 m2 (1.0 US gallon per 1,000 ft2).

Note: Each sprayer tip shuts off when sprayer pressure is <0.3 bar (5 psi) to prevent dripping.

Mixing Product

Calculating the Average Application Rate

To determine about of product to mix for solution of chemical in the tank, you need to understand what nozzle application rate of your machine (the factory installed lavender nozzle tip application rate is 1.3 L/93 m2 (1 / 3 gallon per 1,000 ft2).

For example, a product may specify an application rate range of 33 to 44 ml/93 m2 (1.1 to 1.5 oz per 1,000 ft2). When calibrating the sprayer, use the formula that follows to calculate the average application rate:

Average Application Rate Formula

[lowest application rate] + [highest application rate]= [sum rate]
[sum rate] / 2= average application rate

Example: 33 + 44 ml (1.1 + 1.5 oz) = [77 ml (2.6 oz) sum rate]; 77 ml / 2 (2.6 oz / 2) =38.5 ml/93 m2 (1.3 oz per 1,000 ft2)―the average application rate value

Calculating the Amount of Product for a Solution of Chemical

  1. Multiply the average product application rate by the 1-gallon nozzle tip factor to determine the 1-gallon application rate.

    Example: median application rate value—38 ml/93 m2 (1.3 fl oz per 1,000 ft2) of 1.1 to 1.5) x 3 (lavender nozzle tip—nozzle tip factor) = 3.9 (adjusted application rate)

  2. Multiply the 1-gallon application rate by the amount of chemical solution that you need to add to the spray tank.

    Example: 3.9 (adjusted application rate) x gallons needed. If you are preparing a 114 L (30 US gallon) solution of chemical, use 3.5 L (117 fl oz) of product (3.9 x 30) for 114 L (30 US gallon) of water.

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.

Calibrate the sprayer before you start the spray application; refer to Sprayer Nozzle Application Rate.

Filling the 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: Do not use brackish or reclaimed water in the spray system.

  1. Move the machine to a level surface, move motion-control lever to the NEUTRAL position, shut off the engine, wait for all moving parts to stop, remove key, and engage parking brake.

  2. Ensure that the 3 boom sprayer-control valves are in the OFF position.

  3. Adjust the tank shutoff valves for the spray tank that you are using; refer to Using the Sprayer Tank Shutoff Valves.

  4. Determine the amount of product and water needed to mix the amount of chemical solution as specified by the chemical manufacturer; refer to Calculating the Amount of Product for a Solution of Chemical.

  5. Open the tank cap on the spray tank (Figure 44).

    g312608

    Figure 44

    1. Sprayer-tank cap
    2. Filler neck

  6. Add 3/4 of the required water to the sprayer tank through the filler neck.

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

  7. Loosen the locknut and turn the knob of the throttle valve counterclockwise (Figure 42).

  8. Start the engine and set the throttle midway between the SLOW and FAST positions.

  9. Set the sprayer-pump switch to the ON position (Figure 45).

  10. Move the throttle to the FAST position.

    Note: The water in the tank will circulate.

  11. Add the specified amount of chemical concentrate to the tank as directed by the chemical manufacturer.

    Important: If you are using a wettable-powder chemical, mix the powder with a small amount of water to form a liquid slurry before adding the chemical mixture to the tank.

  12. Add remaining water to the tank and install cap onto the filler neck of the tank.

    Note: Allow the content of the sprayer tank to mix thoroughly.

Important: Before applying chemicals to the job site, adjust the sprayer-pressure with the throttle valve according to the sprayer nozzle application rate.

Spraying with the Sprayer Boom

Important: To ensure that your chemical solution remains well mixed. For the agitation feature to work, set the sprayer-pump switch to the ON position, pull back the tank-agitation lever, and run the engine at high idle. If you shut off the machine and agitation is needed, leave the motion-control lever in the NEUTRAL position, engage the parking brake, increase the throttle to the FAST position, start the sprayer pump and run tank agitation.

Note: Calibrate the sprayer before you start the spray application; refer to Sprayer Nozzle Application Rate.

  1. Press the spray-pump switch on the control console to the OFF position.

  2. Adjust the sprayer-pressure with the throttle valve according to the sprayer nozzle application rate; refer to Adjusting the Sprayer Pressure.

  3. Drive the machine to the job site.

  4. As needed, set the left, center, and right boom sprayer-control valves to the ON position.

  5. Drive the machine and step on the spray-pump foot switch to turn on the spray pump; refer toSpray-Pump Foot Switch.

    Important: Keep your hands on the traction control levers; use the spray-pump foot switch. Use the spray-pump switch on the control console for mixing the tank(s), transferring fluid between tanks, and spraying with the hand wand.

    Note: Step off the spray-pump foot switch to shut off spray pump.

  6. When you finish spraying, move the boom sprayer-control valves are in the OFF position.

    Note: If you need to continue to mix the sprayer tank contents, open the throttle valve, and use the spray-pump switch on the control console.

Spraying Tips

  • Do not overlap the effective spray area that you have previously sprayed (Figure 46).

    g312650

    Figure 46

    1. Overlap area
    2. Effective spray area

  • Watch for plugged sprayer nozzles.

  • Move the boom sprayer-control valves to the OFF position to stop the spray flow before stopping the motion of the machine. Once stopped, leave the motion-control lever in NEUTRAL and leave the sprayer-pump switch in the ON position.

  • You obtain better results if the machine is moving when spray controls are turned ON.

  • Ensure adequate pump pressure for proper spray distribution by push the tank-agitation lever to the OFF position.

  • Watch for changes in the application rate. Changes in the application rate indicate that your ground speed has changed beyond the operating range of the nozzles or there is a problem with the sprayer system.

Note: When the tank is nearly empty, the tank agitation may cause foaming of the chemical solution in the tank. In this case, throttle valve to the OFF position. Alternatively, if an anti-foaming agent compatible with the existing chemical—add the anti-foaming agent according to the manufacturer’s instructions.

Spraying with the Spray Wand

Warning

The 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 the nozzle and do not direct the spray or stream from the wand at people, pets, or non-work area property.

  • Do not direct the spray at or near electrical-power components or source.

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

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

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

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

  • Rotate the spray-wand lock to the OFF position when job is complete.

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

    • While performing maintenance on the machine, someone could start the engine. Accidental starting of the engine could seriously injure you or others. Remove the key from the ignition switch, engage parking brake, and pull the wire(s) off the spark plug(s) before you do any maintenance. Also, push the wire(s) aside so that it does not accidentally contact the spark plug(s).

    • The engine can become very hot. Touching a hot engine can cause severe burns. Allow the engine to cool completely before servicing or repairing around the engine area.

    • Park the machine on level ground and allow it to cool. Never allow untrained personnel to service the machine.

    • Disengage the spray or close the spreader gate, set the parking brake, shut off the engine, and remove the key or disconnect the spark-plug wire. Wait for all movement to stop before adjusting, cleaning, or repairing the machine.

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

    • Relieve the pressure from the spray system before servicing the machine.

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

    • 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; otherwise, gangrene may result.

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

      • Keep your 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 working on the hydraulic system.

    • Raising the machine for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous. The mechanical or hydraulic jacks may not be enough support or may malfunction, allowing the machine to fall and cause possible injury. Do not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands or equivalent support.

    • Carefully release the pressure from components with stored energy.

    • Keep your hands and feet away from moving parts. If possible, do not make adjustments while the engine is running. If the maintenance or adjustment procedure requires the engine to be running and components moving, use extreme caution.

    • Contact with moving parts or hot surfaces may cause personal injury. Keep your fingers, hands, and clothing clear of rotating components and hot surfaces.

    • Check all bolts frequently to maintain their proper tightness.
