The throttle lever is located on the control panel between the seats (Figure 11), and the throttle is used to control the engine speed. Push the lever forward to increase the engine speed and pull it rearward to decrease the engine speed.

Toggle the switch to operate the work lights (Figure 9). Push it forward to turn the lights on and rearward to turn them off.

The fuel gauge is located on the dash of the machine and the gauge displays the level of the fuel in the tank (Figure 9).

The pressure gauge (Figure 13) is located on the dash. This gauge shows the pressure of the fluid in the spray system in psi and kPa.

Use the spray-mode switch to change between the application rate mode (closed loop) and the manual mode (open loop).

The application-rate switch is located on the dash to the right of the steering wheel (Figure 13). Use the application-rate switch to control the spray pump speed when operating the sprayer in the manual mode. Press and hold the switch forward to increase the application rate (pressure), or press and hold it rearward to decrease the application rate (pressure).

The spray-pump switch is located on the center console to the right of the seat (Figure 13). Toggle this switch forward to run the spray pump or rearward to stop the pump. When the switch is turned on, a light on the switch illuminates.

Important: Engage the spray-pump switch only when the engine is at LOW IDLE to avoid damaging the pump drive.

The boom-section lift switches are located on the center console to the right of the seat and used to raise or lower the left and right boom sections (Figure 13).

The master section switch is located on the center console of the machine. This switch allows you to start or stop the spray operation. Press the switch to enable or disable the spray system (Figure 13).

The 3 section switches are located on the center console in the front of the armrest (Figure 13). Toggle each switch forward to turn the corresponding section on and rearward to turn each off. When the switch is in the ON position, an icon appears at the top of the InfoCenter.

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

The agitation switch is located on the center console to the right of the seat (Figure 13). Toggle this switch forward to turn on the agitation in the tank or rearward to stop the agitation. 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 low idle.

The agitation-bypass valve redirects the flow of fluid to the sprayer-system pump when you turn off the agitation function (Figure 14). 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 agitation on or off; refer to Calibrating the Agitation-Bypass Valve.

Figure 14

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

The flow meter measures the flow rate of the fluid for use by the InfoCenter system and when spraying in the application rate mode (Figure 14).

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 sprayer operator 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 15).

Figure 15

1. Agitation-throttle-valve handle

The section bypass valves are used to adjust the sprayer system pressure to the section valves to ensure that the sprayer pressure to the spray section remains constant no matter how many spray sections are on (Figure 16).

Note: Use the bypass valves when spraying in the manual mode (open loop) only.

Figure 16

1. Knob (section-bypass valves)
2. Section-bypass shutoff valve

Use the section-bypass shutoff valve to control fluid flow from the section bypass valves to the tank when spraying in the manual mode (open loop); refer to Figure 16.

Note: Close the section-bypass shut off valve when spraying in the application rate mode (closed loop).

At 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

2. Tank cover

The tank cover is located at the center, top of the tank. To open the cover, shut off the engine, 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.

Check the following items each time you begin use of the sprayer for the day:

• Check the air pressure in the tires.

  Note: The tires of this machine are different than car tires; they require less air pressure to minimize turf compaction and damage.

• Check all fluid levels and add the appropriate amount of specified fluids, if any are found to be low.

• Check the brake pedal operation.

• Check to see that the lights are working.

• Turn the steering wheel to the left and right to check steering response.

• With the engine shut off, check for oil leaks, loose parts, and any other noticeable malfunctions.

If any of the above items are not correct, notify your mechanic or check with your supervisor before taking the sprayer out for the day. Your supervisor may want you to check other items on a daily basis, so ask what inspections you are responsible to perform.

• Check the engine-oil and fluid levels regularly and be alert for indications of overheating in any component of the sprayer.

• After starting a cold engine, let it warm up for about 15 seconds before accelerating.

• Avoid racing the engine.

• Vary the sprayer speed during operation. Avoid fast starts and quick stops.

• Refer to for any special, low-hour checks.

Important: When operating in application rate mode, you must set the section-bypass valves to the closed position.

Important: Whenever possible, do not use reclaimed water (gray water) in the spray tank.

Before using the sprayer for the first time, whenever you change the nozzles, or as needed, calibrate the sprayer flow, speed, and set the section bypass.

Important: Select an open flat area to perform this procedure.

• The agitation-bypass valve is in the full-open position as shown in Figure 30A.

• The agitation-bypass valve is in the closed (0) position as shown in Figure 30B.

• The agitation-bypass valve is in an intermediate (adjusted relative to the pressure gauge for the sprayer system) position as shown in Figure 30C.

There are 2 categories of engine messages that display on the InfoCenter when the engine is running outside the safe operating limit:

• Engine advisories messages

• Stop engine messages

Note: You must set the audio mute option in the InfoCenter to ON for engine advisory and stop engine alarms to sound; refer to Muting the Audio Indicator in the Software Guide for the Multi Pro 5800-D and 5800-G turf sprayers with ExcelaRate spray system.

Note: The symbol at the top right corner of the home screen, an engine advisory message, or a stop engine message indicates that an active fault exists for the engine.

To operate the Multi Pro^® Sprayer, first fill the sprayer tank, apply the product mix to the job site, and finally clean the tank and spray system. It is important that you complete all 3 of these steps in succession to avoid damaging the sprayer. For example, do not mix and add chemicals in the sprayer tank at night and then spray in the morning. This leads to separation of the chemicals and possible damage to the sprayer components.

The Multi Pro^® Sprayer is specifically designed for high durability, provides the long sprayer life. Different materials have been chosen for specific reasons at different locations on your sprayer to meet this goal. Unfortunately, there is no single material which is perfect for all foreseeable applications.

Some chemicals are more aggressive than others and each chemical interacts differently with various materials. Some consistencies (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.

As always, remember to clean your sprayer and spray system thoroughly after all applications. This ensures that your sprayer has a long and trouble-free life.

Note: If you have questions or need additional information regarding the spray-control system, refer to the Operator’s Manual supplied with the system.

Refer to the Software Guide for the Multi Pro 5800-D and 5800-G turf sprayers with ExcelaRate spray system for information on the following:

Refer to the Software Guide for the Multi Pro 5800-D and 5800-G turf sprayers with ExcelaRate spray system for information on the following procedures:

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

The boom-section lift switches on the sprayer control panel allows you to move the outer spray sections between transport position and spray position without leaving the operator's seat. Whenever possible, stop the machine before changing spray section positions.

Important: Under some conditions, heat from the engine, radiator, and muffler can damage grass when operating the sprayer in a stationary mode. Stationary modes include tank agitation, hand spraying with a spray gun, or using a walking boom.

Use the following precautions:

• Avoid stationary spraying when conditions are very hot and/or dry, as turf can be more stressed during these periods.

• Avoid parking on the turf while stationary spraying. Park on a cart path whenever possible.

• Minimize the amount of time the machine is left running over any particular area of turf. Both time and temperature affect how much the grass may be damaged.

• Set the engine speed as low as possible to achieve the desired pressure and flow. This minimizes the heat generated and the air velocity from the cooling fan.

• Allow heat to escape upward from the engine compartment by raising the seat assemblies during stationary operation rather than being forced out under the vehicle.

• Do not overlap areas that you have previously sprayed.

• Watch for plugged nozzles. Replace all worn or damaged nozzles.

• Use the master section switch to stop the spray flow before stopping the sprayer. Once it stops, use the engine-throttle control to hold the engine speed up to keep the agitation running.

• You will obtain better results if the sprayer is moving when you turn the spray sections on.

If a nozzle becomes clogged while you are spraying, clean the nozzle as follows:

1. Stop the sprayer on a level surface, shut off the engine, and engage the parking brake.

2. Set the master section switch to the OFF position and then set the sprayer-pump switch to the OFF position.

3. Remove the clogged nozzle and clean it using a spray bottle of water and a toothbrush.

4. Install the nozzle.

Wash the machine as needed using water alone or with a mild detergent. You may use a rag when washing the machine.

Important: Do not use brackish or reclaimed water to clean the machine.

Note: Do not use power-washing equipment to wash the machine. Power-washing equipment may damage the electrical system, loosen important decals, or wash away necessary grease at friction points. Avoid excessive use of water near the control panel, engine, and battery.

Important: Do not wash the machine with the engine running. Washing the machine with the engine running may result in internal engine damage.

Use a trailer or truck when moving the machine long distances.

• Use full-width ramps for loading the machine onto a trailer or truck.

• Tie outer spray sections to the boom-section transport cradles.

• Bind the machine securely to the transport vehicle; Figure 55 and Figure 56 illustrate the tie-down points of the machine.
