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.

      • 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.

    • Sudden changes in terrain may cause abrupt steering wheel movement, possibly resulting in hand and arm injuries. 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
    • 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 use a new material. The spreader broadcasts material in a pattern 1.5 to 6.7 m (5 to 22 ft) wide depending on the material particle size, volume/density, 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 28 or Figure 29.

      • For larger granule materials:

        Space 6 additional pans, on each side, 12 inches (30 cm) apart (Figure 28).

        g027328
      • For small granule materials:

        Place 6 additional pans, on each side, with no gap in between each pan (Figure 29).

        g027327
    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 30) to the cam setting you determined in step 4.

      g259776
    6. Fill the hopper approximately half-full with the desired material; refer to Filling the Spreader Hopper.

    Determining the Distribution Pattern

    1. Set the spreader pattern control to the middle of its travel; refer to .

    2. Tap the impeller control switch up or down to adjust the broadcasting pattern.

      Record the motor-rotation speed here: %.

    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 28 and Figure 29.

    7. 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.

      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 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 2 graduated cylinder, 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 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; refer to Emptying the Spreader.

    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: 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, wait for all moving parts to stop, remove key, and engage parking brake.

    3. Ensure that the heavy distribution granular-gate lever is in the fully forward (closed) position; refer to Heavy Distribution Granular-Gate Lever.

    4. Use the Spreading Charts to determine the setting for the drop-rate cam (Figure 31).

      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.

      g027326
    5. Remove the cover from the hopper, add the material that you are spreading, and install the cover onto the hopper (Figure 31).

      Note: Do not overload the hopper; the maximum weight capacity of the hopper is 79 kg (175 lb).

      Note: You may place 1 extra bag of granular product on top of the sprayer tank if necessary.

    Adjusting the Spreader Pattern

    If the spreader casts material unequally side-to side—too light/heavy to one side—(see Figure 36 and Figure 37), adjust the spreader-pattern.

    g025543

    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° as shown in 2 of Figure 37.

      g304910
    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 37.

      • 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 37.

    3. Lock the spreader-pattern control by turning the handle clockwise 90°; refer to 5 of Figure 37.

    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 block the granular material.

    • Pull the knob to raise the deflector to cast materials normally at the left side of the machine.

    Spreading Material

    1. Start the engine, and adjust the throttle midway between the SLOW and the FAST positions (Figure 39).

      g305555
    2. Tap the top of the impeller control switch to run the impeller motor (Figure 39).

      Note: The spreader controller runs the impeller motor at the last speed setting to which you adjusted it.

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

    4. Open the either the narrow or wide impeller-gate lever to begin spreading (Figure 40).

      Note: Use the flow-rate adjustment knob to control the discharge rate of the granular material from the hopper onto the impeller when the light distribution granular-gate lever is in the OPEN position.

      g027497
    5. Evaluate the spread pattern.

      Note: If you need to adjustment the spreading pattern, refer to Adjusting the Spreader Pattern.

    6. When you are finished spreading, close the heavy distribution granular-gate lever.

      Note: Only the heavy distribution granular-gate lever closes the impeller gate. Pushing the heavy distribution granular-gate lever forward also resets the light distribution granular-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.

    Spreading Tips

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

    g027374
    • To ensure uniform application, broadcast the material in an overlapping pattern as shown in Figure 41.

      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.

    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 Application Rate Tables, 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 (0.8 gpm)

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

    Liter per 100 m2 Application Rate

    Single nozzle capacity (Lpm) x Number of nozzles x 6=L
    Speed (kph) x Spray width (m)100 m2

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

    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, wait for all moving parts to stop, remove key, and engage parking brake.

    2. Ensure that the narrow-spray pattern and wide-spray pattern levers are in the OFF position and the handle for the drain valve for the tank rotated 90° counterclockwise to the is CLOSED position (Figure 52).

      g027391
    3. Determine the amount of water needed to mix the amount of chemical needed as specified by the chemical manufacturer.

    4. Open the tank cap on the spray tank (Figure 52).

    5. 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.

    6. Rotate the pump-shutoff valve clockwise to the OPEN position (Figure 53).

      g027392
    7. Start the engine and set the throttle midway between the SLOW and FAST positions.

    8. Set the sprayer-pump switch to the ON position (Figure 54).

      g305521
    9. Move the throttle to the FAST position.

    10. Pull the tank-agitation lever to the ON 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.

    Emptying the Sprayer Tank

    Operator supplied equipment:

    • A drain hose with a 1/2–14 inch NPT male coupling

    • A drain container (capacity varies with remaining sprayer tank content)

    • PTFE thread sealant

    1. Move the machine to a level surface at the designated area for emptying and cleaning the sprayer tank, 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. Remove the plug from the drain valve for the sprayer tank (Figure 55).

      Note: The drain valve is located at the left side of the machine.

      g025542
    3. Thread a drain hose (operator provided) into the end of the drain valve.

    4. Put the free end of the drain hose into a container with enough capacity to hold the remaining content of the sprayer tank.

      Note: Use the quantity marks at the front, left side of the sprayer tank for determine the quantity of chemical solution in the tank.

    5. Rotate the handle for the drain valve clockwise 90° to drain the tank (Figure 55).

      Allow the sprayer tank to drain completely.

    6. Apply PTFE thread sealant to the threads of the plug.

    7. Close the tank-drain valve, remove the drain hose, and install the drain plug into the valve (Figure 55).

      Note: Dispose of the sprayer chemicals according to local codes and the chemical manufacturer's instructions.

    Spraying with the Sprayer Boom

    Important: To ensure that your chemical solution remains well mixed, use the agitation feature whenever you have solution in the tank. 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 Calibrating the Sprayer.

    1. Tap the sprayer-pump switch to the ON position.

    2. Drive the machine to the job site.

    3. Push the tank-agitation lever to the OFF position.

      Note: There is some agitation effect even while the tank-agitation lever is in the OFF position.

    4. Use the sprayer-pump switch to adjust the spray pressure to the setting that you determined in Nozzle Application Rate Tables.

    5. Move the narrow or wide-spray pattern lever to the ON position and begin spraying.

      Important: Do not use both the narrow and wide controls at the same time.

      g027299
      g027299
    6. When you finish spraying, push forward the spray-pattern levers and set the sprayer-pump switch to the OFF position.

      Note: If you need to continue to mix the sprayer tank contents, leave the sprayer-pump switch in the ON position, and pull the tank-agitation lever.

    Spraying Tips

    g027300
    • Do not overlap the effective spray area that you have previously sprayed (see Figure 58).

    • Watch for plugged sprayer nozzles.

    • Move the narrow-and wide-spray pattern levers 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, push the tank-agitation lever 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. Remove the wand from the holder at the right side of the machine (Figure 59).

      g305609
    2. Firmly grip the spray wand and point it in the direction that you will spray.

      Note: The wand may recoil; ensure that you hold it securely.

    3. Adjust the pump pressure to the spray wand perform the following:

      • To increase the pump pressure to the wand, rotate the wand-pressure control counterclockwise (Figure 60).
