Multi Pro® 5800-D 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 allow untrained people to operate or service the equipment.

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

• The owner/operator can prevent and is responsible for accidents or injuries occurring to 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 that they work properly. If they do not, drive slowly while putting light pressure on the brake pedal to dry the brakes.

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 suddenly apply 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 takes longer than stopping on level ground. If you must stop the sprayer, avoid sudden speed changes, which may initiate tipping or rolling of the sprayer. Do not suddenly apply 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.

  Use care when driving the machine in terrain that changes abruptly.

• 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:

• 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 forward and reverse movement of the machine. 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 the machine in reverse. Release the pedal to slow and stop the machine.

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 travels. To obtain maximum forward speed, set the throttle lever to the FAST position and press the traction pedal fully forward.

Note: To get maximum power under heavy load or when ascending a hill, have the throttle in the FAST position while pressing the 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.

The boom-section switches are located on the center console in front of the armrest (Figure 10). Toggle each switch forward to turn the corresponding boom section on and rearward to turn each off. When the switch is in the ON position, an icon appears on the InfoCenter.

Note: These switches affect only the spray system when the master-boom switch is in the ON position.

The pump switch is located on the center console to the right of the seat (Figure 10). Toggle this switch forward to run the pump or rearward to stop the pump.

Important: Engage the pump only when the engine is at low idle to avoid damaging the pump drive.

The raise/lower-boom switches are located on the center console to the right of the seat and used to raise or lower the left and right booms (Figure 10).

The agitation switch is located on the center console to the right of the seat (Figure 10). Toggle this switch forward to turn on the agitation in the tank or rearward to stop the agitation. When you turn on the switch, a light on the switch illuminates. To operate the agitation function, run the sprayer-system pump and run the engine above low idle. The agitation valve is located behind the tank (Figure 11).

Figure 11

1. Actuator (agitation valve)
2. Agitation-bypass-valve handle

The agitation-bypass valve redirects the flow of fluid to the sprayer-system pump when you turn off the agitation function (Figure 11). The agitation-bypass valve is located above the agitation valve. You can adjust the bypass valve to ensure that the pressure remains constant when cycling the agitation on and off; refer toCalibrating 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. 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 agitation-throttle valve is located above the pump (Figure 12).

Figure 12

1. Agitation-throttle-valve handle

The section valves control sprayer flow to the 3 boom sections, and you can turn them on or off with the valves (Figure 13).

Figure 13

1. Knobs (section-bypass valve)
2. Actuators (section valve)

The boom bypass redirects the fluid flow for a boom section to the tank when you turn off the boom section. You can adjust the boom bypass to ensure that the boom pressure remains constant no matter how many booms sections are on.

Located toward the front of the tank cover, is a hose receptacle with a threaded fitting, a 90-degree barbed fitting, and a short hose 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.
