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).

• Read the Operator's Manual and other training material before operating the machine.

  Note: If the operator(s) or mechanic(s) cannot read the manual language, it is the owner's responsibility to explain this material to them.

• Become familiar with the safe operation of the equipment, operator controls, and safety signs.

• All operators and mechanics should be trained. The owner is responsible for training the users.

• Never untrained people operate or service the equipment.

  Note: Local regulations may restrict the age of the operator.

• The owner/user can prevent and is responsible for accidents or injuries occurring to himself or herself, other people, or damage to property.

• 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.

  Warning

  Sudden changes in terrain may cause abrupt steering wheel movement, possibly resulting in hand and arm injuries.

• Reduce your speed when operating on rough terrain and near curbs.

• Grip the steering wheel loosely around the perimeter. Keep your hands clear of the steering wheel spokes.

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 8) 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. To operate the agitation function, you must run the sprayer system pump and you must run the engine above an idle. The agitation valve is located behind the tank (Figure 15)

Figure 15

1. Actuator (agitation valve)
2. Handle (agitation throttle valve)
3. Handle (agitation bypass)

The agitation bypass valve redirects the flow of fluid to the sprayer system pump when you turn off the agitation function (Figure 15). The agitation bypass valve is located at the above of the agitation valve. You can adjust the bypass valve to ensure that pressure remains constant during agitation; refer to Calibrating the Agitation Bypass Valve.

The agitation throttle valve is a manually operated ball valve that controls flow to the agitation nozzles in the main tank (Figure 15). Using this valve allows the user to control the sprayer system pressure at the agitation nozzles of the main tank when larger application rates are required.

The section valves control flow to the 3 boom sections (Figure 16). If you ever need to manually turn off a section, rotate the knob on the valve clockwise to turn the valve off or counterclockwise to turn it on.

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

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.

Cooling system capacity: 5.5 L (5.8 US qt)

Coolant type: a solution of 50% water and 50% permanent ethylene glycol antifreeze

Important: Do not add coolant to an overheated engine until the engine has fully cooled. Adding coolant to an overheated engine may crack the engine block.

Check the engine coolant concentration as directed by the coolant manufacturer.

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

   Caution

   If the engine has been running, the coolant may be hot and pressurized. If you open the radiator cap when the coolant is hot, it could spray out and severely burn you or bystanders.

   Allow the engine to cool for at least 15 minutes before opening the radiator cap. The radiator cap must be cool to the touch.

2. When the engine is cool, remove the radiator cap (Figure 66).

   3. Expansion tank cap
   4. Full line, expansion tank

3. Place a large drain pan under the radiator.

4. Open the drain (Figure 67) and drain the coolant into the pan.

   

   Figure 67

5. Close the drain (Figure 67).

6. Remove the radiator cap (Figure 66).

7. Slowly fill the radiator with coolant to approximately 2.5 cm (1 inch) below the sealing surface of the cap.

   Note: Use enough coolant to fill the engine and the system lines. This will allow for the coolant to expand without it overflowing while the engine is warming up.

8. Start the engine with the cap loosely on the radiator (Figure 66).

9. Allow the engine to warm up until the thermostat opens.

   Note: This usually occurs between 175 and 190 degrees F.

   Caution

   As the engine continues to run, the coolant will become hot and pressurized. If you open the radiator cap when the coolant is hot, it could spray out and severely burn you or bystanders.

   • Allow the engine to cool for at least 15 minutes before opening the radiator cap. The radiator cap must be cool to the touch.

   • Wear protective clothing and avoid contact with hot coolant as you open the radiator cap.

10. Once the coolant has warmed up, top off the coolant level to the sealing surface of the cap and tighten the cap (Figure 66).

11. Open the expansion tank cap and fill the tank with coolant to the Cold level (Figure 66).

12. Check the coolant levels after several engine start up and shut down cycles.

    Note: Add coolant to the radiator and expansion tank as needed.

If the brake pedal travels more than 2.5 cm (1 inch) before you feel resistance, adjust the brakes as follows:

1. Position the sprayer on a level surface, stop the pump, stop the engine, and remove the key from the starter switch.

2. Set the parking brake.

3. Put the blocks under the wheels to prevent the machine from rolling.

4. Release the parking brake.

5. Loosen the front nuts on the brake cables under the front end of the sprayer (Figure 68).

   

   Figure 68

   1. Front nuts
   2. Rear nuts

6. Tighten the rear nuts equally until the brake pedal moves between 1 to 2 cm (1/2 to 1 inch) before you feel resistance (Figure 68).

   Important: Ensure that you tighten both rear nuts equally so that the threaded ends of the brake cables in front of the front nuts are the same length.

7. Tighten the front nuts.

Check the condition and tension of the alternator/cooling fan belt. Replace the belt as necessary.

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

2. Check the tension by depressing the belt midway between the alternator and the crankshaft pulleys with 10 kg (22 lb) of force.

   Note: The belt should deflect 10 to 12 mm (0.39 to 0.47 inches). If the deflection is not correct, go to 3. If it is correct, you may skip the remainder of this procedure and resume operating the sprayer.

3. Loosen the bolts that secure the brace to the engine and the bolt that secures the alternator to the brace (Figure 69).

   

   Figure 69

   2. Brace
   3. Alternator
   4. Bolts

4. Insert a pry bar between the alternator and the engine and carefully pry on the alternator outward.

5. When you achieve the proper tension, tighten the alternator and the bolts to secure the adjustment.

6. Tighten the locknut to secure the adjustment.

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.

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.
