Multi-Pro 5800 Turf Sprayer

• Make sure that operators are thoroughly trained and familiar with the Operator's Manual, engine owner’s manual, and all labels on the sprayer.

• Establish your own special procedures and work rules for unusual operating conditions (e.g. slopes too steep for sprayer operation).

• Slow down before you approach an obstacle. This gives you extra time to stop or turn away. Hitting an obstacle can damage the sprayer and its contents. More important, it can injure you.

• Gross Vehicle Weight (GVW) has a major impact on your ability to stop and/or turn. Heavy loads and attachments make a sprayer harder to stop or turn. The heavier the load, the longer it takes to stop.

• Turf and pavement are much more slippery when they are wet. It can take 2 to 4 times as long to stop on wet surfaces as on dry surfaces. If you drive through standing water deep enough to get the brakes wet, they will not work well until they are dry. After driving through water, you should test the brakes to make sure they work properly. If they do not, drive slowly while putting light pressure on the brake pedal. This will dry the brakes out.

Operating the sprayer on a hill may cause tipping or rolling of the sprayer, or the engine may stall and you could lose headway on the hill. This could result in personal injury.

• Do not accelerate quickly or slam on the brakes when backing down a hill, especially with a load.

• Never drive across a steep hill; always drive straight up or down or go around the hill.

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

• Turning while traveling up or down hills can be dangerous. If you have to turn while on a hill, do it slowly and cautiously. Never make sharp or fast turns.

• Heavy loads affect stability. Reduce the weight of the load and your speed when operating on hills.

• Avoid stopping on hills, especially with a load. Stopping while going down a hill will take longer than stopping on level ground. If the sprayer must be stopped, avoid sudden speed changes, which may initiate tipping or rolling of the sprayer. Do not slam on the brakes when rolling backward, as this may cause the sprayer to overturn.

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

The weight of the cargo can change the sprayer center of gravity and sprayer handling. To avoid loss of control and personal injury, follow these guidelines:

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

• Liquid loads can shift. This shifting happens most often while turning, going up or down hills, suddenly changing speeds, or while driving over rough surfaces. Shifting loads can cause the sprayer to tip over.

• When operating with a heavy load, reduce your speed and allow for sufficient braking distance. Do not suddenly apply the brakes. Use extra caution on slopes.

• Be aware that heavy loads increase your stopping distance and reduce your ability to turn quickly without tipping over.

The traction pedal (Figure 7) controls the movement of the machine, both forward and reverse. Using the heel and toe of the right foot, press the top of the pedal to move forward or the bottom of the pedal to move in reverse. Release the pedal to slow and stop.

Important: Ensure that you allow the sprayer to come to a stop before switching between the Forward and the Reverse positions.

Note: The farther you press the pedal in either direction, the faster the sprayer will travel. To obtain maximum forward speed, set the throttle lever to the Fast position and press the traction pedal all the way forward.

Note: To get maximum power under heavy load or when ascending a hill, have the throttle in the Fast position while pressing traction pedal slightly to keep the engine speed high. When the engine speed begins to decrease, release the traction pedal slightly to allow the engine speed to increase.

When the switch is turned on, a light on the switch illuminates. For agitation to work, the pump must be on and the engine must be running above an idle. The agitation valve is located behind the tank (Figure 14)

Figure 14

1. Agitation valve
2. Boom valves

The agitation bypass valve redirects the fluid flow to the pump when you turn off agitation (Figure 15). It is located at the back of the agitation valve. You can adjust this valve to ensure that pressure remains constant during agitation. Refer to Calibrating the Agitation Bypass Valve.

Figure 15

1. Agitation bypass valve

The agitation control valve is a manual ball valve that controls flow to the agitation nozzles in the main tank (Figure 16). Using this valve allows the user further control over pressure at the agitation nozzles of the main tank when larger application rates are required.

Figure 16

1. Agitation control valve, open

These valves turn the 3 booms on or off (Figure 14). If you ever need to manually turn off a boom, rotate the knob on the valve clockwise to turn the valve off or counterclockwise to turn it on.

Note: Turning the boom valve manually can interfere with the function of the fuses. The fuses should be checked after manually rotating the valve.

If you install the Pro Foam Marker kit, you will add switches to the control panel for controlling their operation. The sprayer comes with plastic plugs in these locations.

If you install the Ultra Sonic Boom, you will add a switch to the dash for controlling its operation. The sprayer comes with a plastic plug in this location.

To the front of the tank cover is a hose receptacle with a threaded fitting, a 90-degree barbed fitting, and a short hose which you can direct toward the tank opening. This receptacle allows you to connect a water hose to it and fill the tank with water without contaminating the hose with the chemicals in the tank.

Important: Do not lengthen the hose to allow contact with the tank fluids. The distance from the end of the hose to the uppermost water level should be within local regulatory limits.

Figure 17

1. Anti-siphon fill receptacle
2. Tank cover

The tank cover is located in the center of the top of the tank. To open it, turn off the engine, then turn the front half of the cover to the left and swing it open. You can remove the strainer inside for cleaning. To seal the tank, close the cover and rotate the front half toward the right.

Note: The best time to check the engine oil is when the engine is cool, before it has been started for the day. If it has already been run, allow the oil to drain back down to the sump for at least 10 minutes before checking. If the oil level is at or below the Add mark on the dipstick, add oil to bring the oil level to the Full mark. Do not overfill. If the oil level is between the Add and Full marks, you do not need to add oil.

The engine is shipped with oil in the crankcase; however, the level of oil must be checked before you first start the engine and after you have run it.

1. Position the machine on a level surface.

2. Remove the dipstick, located under the passenger seat, and wipe it with a clean rag (Figure 18).

   Note: Insert the dipstick into the tube and make sure it is seated fully. Remove the dipstick and check the oil level.

   

   Figure 18

   1. Dipstick

3. If the oil level is low, remove the filler cap from the valve cover (Figure 19) and pour oil into the opening until the oil level is up to the Full mark on the dipstick; refer to Servicing the Engine Oil for the proper oil type and viscosity.

   Note: Add the oil slowly and check the level often during this process. Do not overfill.

   

   Figure 19

4. Install the filler cap.

5. Install the dipstick firmly in place.

Check the tire pressure every 8 hours or daily to ensure proper levels. Fill the tires to 124 kPa (18 psi). Also, check the tires for wear or damage.

Important: Your engine runs on No. 2-D or 1-D automotive-type diesel fuel with a minimum cetane rating of 40.

Note: Your engine may require a higher cetane-rated fuel if you operate the machine at high altitudes or in low atmospheric temperatures.

Using Biodiesel Fuel

This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petrodiesel). The petrodiesel portion should be low or ultra low sulfur. Observe the following precautions:

• The biodiesel portion of the fuel must meet specification ASTM D6751 or EN14214.

• The blended fuel composition should meet ASTM D975 or EN590.

• Painted surfaces may be damaged by biodiesel blends.

• Use B5 (biodiesel content of 5%) or lesser blends in cold weather.

• Monitor seals, hoses, gaskets in contact with fuel as they may be degraded over time.

• Fuel filter plugging may be expected for a time after converting to biodiesel blends.

• Contact your distributor if you wish for more information on biodiesel.

The sprayer is equipped with a boom transport cradle that has a unique safety feature. In the event of accidental boom contact with a low overhead object while in the transport position, the boom(s) can be pushed out of the transport cradles. If this occurs, the booms will come to rest in a near horizontal position to the rear of the vehicle. While the booms will not be damaged due to this movement, they should be immediately put back into the transport cradle.

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

To put the booms back into the transport cradle, lower the boom(s) to the spray position, and then raise the boom(s) back into the transport position. Make sure the boom cylinders are fully retracted to prevent actuator rod damage during storage.

Whenever the engine is run for routine maintenance and/or engine diagnostics, the rear wheels of the sprayer should be 25 mm (1 inch) off the ground with the rear axle supported on jack stands.

The jacking point at the front of the sprayer is under the front axle, directly under the leaf springs (Figure 32).

The machines reservoir is filled at the factory with approximately 56 L (15 US gallons) of high quality hydraulic fluid. Check the level of the hydraulic fluid before the engine is first started and daily thereafter. The recommended replacement fluid is as follows:

Alternate fluids: If the Toro fluid is not available, other fluids may be used provided they meet all the following material properties and industry specifications. We do not recommend the use of synthetic fluid. Consult with your lubricant distributor to identify a satisfactory product Note: Toro will not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendation.

Important: The ISO VG 46 Multigrade fluid has been found to offer optimal performance in a wide range of temperature conditions. For operation in consistently high ambient temperatures, 18° C (65° F) to 49° C (120° F), ISO VG 68 hydraulic fluid may offer improved performance.

Premium Biodegradable Hydraulic Fluid-Mobil EAL EnviroSyn 46H

Important: Mobil EAL EnviroSyn 46H is the only synthetic biodegradable fluid approved by Toro. This fluid is compatible with the elastomers used in Toro hydraulic systems and is suitable for a wide-range of temperature conditions. This fluid is compatible with conventional mineral oils, but for maximum biodegradability and performance the hydraulic system should be thoroughly flushed of conventional fluid. The oil is available in 5-gallon (19 L) containers or 55-gallon drums from your Mobil Distributor.

Important: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system oil is available in 20 ml (2/3 oz) bottles. One bottle is sufficient for 15 to 22 L (4 to 6 US gallons) of hydraulic oil. Order part no. 44-2500 from your authorized Toro distributor. This red dye is not recommended for use with biodegradable fluids; use food coloring.

1. Position the sprayer on a level surface, set the parking brake, stop the pump, stop the engine, and remove the ignition key.

2. Stop the pump, stop the engine, and remove the ignition key.

3. Clean the area around the hydraulic-oil-tank dipstick cap and remove it (Figure 59).

6. If the oil is low, fill the tank with the specified hydraulic fluid or equivalent to raise the level to the upper mark.

7. Install the dipstick cap into the tank and secure.

If the oil becomes contaminated, contact an Authorized Toro Distributor to have the system flushed.

Note: Contaminated oil looks milky or black when compared to clean oil.

Examine each hose in the spray system for cracks, leaks or other damage. At the same time, inspect the connections and fittings for similar damage. Replace any hoses and fittings if damaged.

The following procedure can be used to adjust the length of the actuator rods.

1. Extend the booms to the spray position.

2. Remove the cotter pin from the pivot pin (Figure 64).

6. Turn the eyelet rod in the actuator rod to shorten or lengthen the extended actuator to the desired position (Figure 65).

   Note: The eyelet rod must be turned in half or complete revolutions to allow the reassembly of the rod to the boom.

7. Once the desired position has been achieved, tighten the jam nut to secure the actuator and eyelet rod.

8. Raise the boom to align the pivot with the actuator rod. While holding the boom, insert the pin through both boom pivot and actuator rod (Figure 64).

9. With the pin in place, release the boom and secure the pin with the cotter removed previously.

10. Repeat the procedure for each actuator rod bearing if necessary.

1. Position the sprayer on a level surface, set the parking brake, stop the pump, stop the engine, and remove the ignition key.

2. Extend the booms to the spray position and support the booms using stands or straps from a lift.

3. With the weight of the boom supported, remove the bolt and nut securing the pivot pin to the boom assembly (Figure 66).

4. Remove the pivot pin (Figure 66).

5. Remove the boom and pivot bracket assembly from the center frame to access the nylon bushings.

6. Remove and inspect the nylon bushings from the front and back sides of the pivot bracket (Figure 66).

   Note: Replace any damaged bushings.

7. Place a small amount of oil on the nylon bushings and install them into pivot bracket.

8. Install the boom and pivot bracket assembly into the center frame, aligning the openings (Figure 66).

9. Install the pivot pin and secure it with the bolt and nut removed previously.

10. Repeat this procedure for each boom.

Once the main tank has been filled with water, check to see if there is any play in the tank straps. If the straps are loose, tighten the fasteners at the top straps until they are flush with tank. Do not over tighten.

Important: Over tightening the tank strap fasteners can result in deforming and damaging the straps.

1. Position the sprayer on a level surface, set the parking brake, stop the pump, stop the engine, and remove the ignition key.
