    • Operate the machine only in good visibility. Avoid holes or hidden hazards.

    • Before you start the engine, ensure that you are in the operating position, the traction pedal is in the NEUTRAL position, and the parking brake is engaged.

    • Remain seated whenever the machine is in motion. Keep both hands on the steering wheel whenever possible, and always keep your arms and legs within the operator’s compartment.

    • Use care when approaching blind corners, shrubs, trees, or other objects that may obscure your vision.

    • Before backing up, look rearward and ensure that no one is behind you. Back up slowly.

    • Never spray while people, especially children, or pets are nearby.

    • Do not operate the machine near drop-offs, ditches, or embankments. The machine could suddenly roll over if a wheel goes over the edge or if the edge gives way.

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

    • Stop the machine, shut off the engine, remove the key, engage the parking brake, and inspect for damage after striking an object or if there is an abnormal vibration in the machine. Make all necessary repairs before resuming operation.

    • Slow down and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.

    • Use extra caution when operating the machine on wet surfaces, in adverse weather conditions, at higher speeds, or with a full load. Stopping time and distance increase in these conditions.

    • Do not touch the engine or muffler while the engine is running or soon after it has shut off. These areas may be hot enough to cause burns.

    • Before you leave the operator’s position, do the following:

      • Park the machine on a level surface.

      • Move the traction pedal to the NEUTRAL position.

      • Shut off the spray pump.

      • Engage the parking brake.

    • Do not remove the ROPS from the machine.

    • Fasten the seat belt and ensure that you can release it quickly in an emergency. Always wear your seat belt.

    • Check carefully for overhead obstructions and do not contact them.

    • Keep the ROPS in safe operating condition by thoroughly inspecting it periodically for damage and keeping all the mounting fasteners tight.

    • Maintain and clean the seat belt(s) as necessary.

    • Replace any damaged ROPS component. Do not repair or alter it.

    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.

    • 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.

    • 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.

    Operating the Sprayer

    To operate the sprayer: fill the sprayer tank, apply the product mix to the job site, and clean the tank and spray system. You must 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.

    Caution

    Chemicals are hazardous and can cause personal injury.

    • Read the directions on the chemical labels before handling the chemicals and 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 appropriate personal protective equipment (PPE) per the chemical manufacturer’s instructions.

    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.

    8. If the fluid level in the graduated catch container is 7.4 ml (1/4 fl oz) more or less than the nozzle volume in the 15-second catch test table, perform 1 of the following:

      • Perform a flow calibration, or replace worn nozzles and perform a flow calibration; refer to the flow calibration procedure in the Software Guide for the Multi Pro 5800-D and 5800-G turf sprayer with ExcelaRate spray system.

      • Calibrate the agitation bypass valve, or replace worn nozzles and calibrate the agitation bypass valve; refer to Calibrating the Agitation-Bypass Valve.

    Positioning the Spray Sections

    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.

    Changing the Spray Section Position

    Perform the following steps to move the outer spray sections to the SPRAY position:

    1. Park the machine on a level surface.

    2. Use the boom-section lift switches to lower the outer sections.

      Note: Wait until the outer spray sections reach the full, extended spray position.

    Complete the sprayer job, then perform the following steps to retract the outer spray sections into the transport position:

    Important: If your machine has the Drift Reduction Boom Shroud Kit, the Ultra Sonic Boom Leveling Kit installed, or both move the outer spray sections to the transport position one at a time.Moving both outer spray sections at the same time with the shroud kit or leveling kit installed may damage the shrouds, the sensors, or both.

    1. Park the machine on a level surface.

    2. Use the boom-section lift switches to raise the outer spray sections, until they have moved completely into boom-section transport cradles forming the “X” transport position, and the lift cylinders are fully retracted.

      Important: Release the boom-section lift switch(es) once the outer spray sections have reached the desired position. Running the actuators against the mechanical stops may damage the lift cylinders and/or other hydraulic components.

      g239336

    Important: To prevent damage to the lift cylinder, make sure that the actuators are fully retracted before transporting the machine.

    Using the Boom-Section Transport Cradle

    The sprayer is equipped with boom-section transport cradles that have a unique feature. In the event the spray section accidentally contacts with a low overhead object while in the transport position, you can push the spray section(s) out of the transport cradles. If this occurs, the spray sections come to rest in a near horizontal position to the rear of the machine. While this movement will not damage the spray sections, they should be immediately positioned into the transport cradle.

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

    To put the outer spray sections back into the transport cradle, lower the spray section(s) to the spray position and then raise the spray section(s) back to the transport position. Make sure that the lift cylinders are fully retracted to prevent damaging the actuator rod.

    Taking Proper Turf Care Precautions while Operating in Stationary Modes

    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.

    Spraying Tips

    • 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.

    Unclogging a Nozzle

    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.

    Cooling System Maintenance

    Cooling System Safety

    • Swallowing engine coolant can cause poisoning; keep out of reach from children and pets.

    • Discharge of hot, pressurized coolant or touching a hot radiator and surrounding parts can cause severe burns.

      • Always allow the engine to cool at least 15 minutes before removing the radiator cap.

      • Use a rag when opening the radiator cap, and open the cap slowly to allow steam to escape.

    • Do not operate the machine without the covers in place.

    • Keep your fingers, hands, and clothing clear of the rotating fan and drive belt.

    Coolant Specification

    The coolant reservoir is filled at the factory with a 50/50 solution of water and ethylene glycol base extended-life coolant. Check the coolant level before you first start the engine and daily thereafter; refer to Checking the Coolant Level.

    The following commercially available coolants or a manufacturer-specified equivalent meeting the long-life coolant specification:

    Extended-Life Coolant Products

    Ford (Motorcraft™)

    WSS-M97B44-D

    FCA—Chrysler (Mopar™)

    MS-12106

    General Motors (AC Delco™)

    GM6277M (Dex-Cool™)

    GMW 3420

    Volkswagen

    G12

    G12+

    G12++

    Coolants meeting technical standards ASTM D3306 or D4985, or SAE J1034, J814, or 1941.

    Important: Do not rely on the color of the coolant to identify the difference between conventional (IAT) and extended-life (OAT) coolant types.Coolant manufacturers may dye extended-life coolant (OAT) in one of the following colors: red, pink, orange, yellow, blue, teal, violet, and green.

    Coolant Types

    Ethylene-Glycol Coolant Type

    Corrosion Inhibitor Type

    Service Interval

    Extended-life antifreeze

    Organic-acid technology (OAT)

    5-years

    Conventional antifreeze (green)

    Inorganic-acid technology (IAT)

    2-years

    Note: When adding coolant to the machine, you will not damage the cooling system by mixing conventional (IAT) antifreeze with extended-life (OAT) antifreeze. However, mixing antifreeze types degrades the long life/extended life attribute of the OAT formulation.

    Important: The service interval of conventional (IAT) and extended-life (OAT) blended-coolant mixture—at any ratio—lasts as long as the coolant with the shortest service interval: 2 years.

    Checking the Coolant Level
