Multi Pro 1200/1250 Page1 -- 2 Safety Safety Instructions The Multi Pro 1200 and Multi Pro 1250 Turf Sprayers are designed and tested to offer safe service when operated and maintained properly. Although hazard control and accident prevention are partially dependent upon the design and configuration of the machine, these factors are also dependent upon the awareness, concern and proper training of the personnel involved in the operation, transport, maintenance and storage of the machine. Improper use or maintenance of the machine can result in injury or death. To reduce the potential for injury or death, comply with the following safety instructions. WARNING To reduce the potential for injury or death, comply with the following safety instructions. Before Operating 1. Read and understand the contents of the Operator’s Manual before starting and operating the machine. Be- come familiar with the controls and know how to stop the machine and engine quickly. Additional copies of the Operator’s Manual are available on the internet at www.Toro.com. 2. Keep all shields, safety devices and decals in place. If a shield, safety device or decal is defective, illegible or damaged, repair or replace it before operating the machine. Also tighten any loose nuts, bolts or screws to ensure machine is in safe operating condition. 3. Assure interlock switches are adjusted correctly so engine cannot be started unless range selector is in NEUTRAL. 4. Since gasoline is highly flammable, handle it carefully: A. Store fuel in containers specifically designed for this purpose. B. Do not remove machine fuel tank cap while engine is hot or running. C. Do not smoke while handling fuel. D. Fill fuel tank outdoors and only to within an inch of the top of the tank, not the filler neck. Do not overfill the fuel tank. E. Wipe up any spilled fuel. While Operating 1. Sit on the seat when starting and operating the machine. 2. Before starting the engine: A. Engage the parking brake. B. Make sure range selector is in NEUTRAL and the pump switch is OFF. 3. Do not run engine in a confined area without ade- quate ventilation. Exhaust fumes are hazardous and could possibly be deadly. 4. Do not touch engine, muffler, exhaust pipe or drive system components while engine is running or soon after it is stopped. These areas could be hot enough to cause burns. 5. Before getting off the seat: A. Ensure that range selector is in neutral. B. Set parking brake. C. Turn pump switch OFF. D. Stop engine and remove key from ignition switch. E. Do not park on slopes unless wheels are chocked or blocked. 6. Follow chemical manufacturer’s recommendations for handling precautions, necessary protective equipment, mixing proportions and clean up procedures.

Rev. A Multi Pro 1200/1250 Page1 -- 3 Safety Maintenance and Service 1. Before servicing or making adjustments, turn spray pump off, put range selector in neutral, stop engine, set parking brake and remove key from the switch. 2. Prior to servicing sprayer components, determine what chemical(s) have been used in the sprayer. Follow precautions and recommendations printed on chemical container labels or Material Safety Data Sheets when servicing sprayer components. Use appropriate protective equipment: protective clothing, chemical resistant gloves and eye protection. 3. Make sure machine is in safe operating condition by keeping all nuts, bolts and screws tight. 4. Never store the machine or fuel container inside where there is an open flame, such as near a water heat- er or furnace. 5. Make sure all hydraulic line connectors are tight and all hydraulic hoses and lines are in good condition before applying pressure to the system. 6. Keep body and hands away from pin hole leaks in hydraulic lines that eject high pressure hydraulic fluid. Use cardboard or paper to find hydraulic leaks. Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid accidentally injected into the skin must be surgically removed within a few hours by a doc- tor familiar with this form of injury or gangrene may result. 7. Before disconnecting or performing any work on the hydraulic system, all pressure in system must be re- lieved. To relieve system pressure, rotate steering wheel in both directions after the key switch has been turned off. 8. If major repairs are ever needed or assistance is de- sired, contact an Authorized Toro Distributor. 9. To reduce potential fire hazard, keep engine area free of excessive grease, grass, leaves and dirt. Clean protective screen on machine frequently. 10.If engine must be running to perform maintenance or an adjustment, keep hands, feet, clothing and other parts of the body away from moving parts. Keep by- standers away. 11. Do not overspeed the engine by changing governor setting. To assure safety and accuracy, check maximum engine speed. 12.Shut engine off before checking or adding oil to the crankcase. 13.Disconnect battery before servicing the machine. Disconnect negative battery cable first and positive cable last. If battery voltage is required for troubleshooting or test procedures, temporarily connect the battery. Reconnect positive cable first and negative cable last. 14.Battery acid is poisonous and can cause burns. Avoid contact with skin, eyes and clothing. Protect your face, eyes and clothing when working with a battery. 15.Battery gases can explode. Keep cigarettes, sparks and flames away from the battery. 16.To assure optimum performance and continued safety of the machine, use genuine Toro replacement parts and accessories. Replacement parts and accessories made by other manufacturers may result in non- conformance with the safety standards and the warran- ty may be voided. 17.When changing attachments, tires or performing other service, use correct jacks, hoists and jack stands. Make sure machine is parked on a solid level surface such as a concrete floor. Prior to raising the machine, remove any attachments that may interfere with the safe and proper raising of the machine. Always chock or block wheels. Use jack stands to support the raised machine. If the machine is not properly supported by jack stands, the machine may move or fall, which may result in personal injury (see Jacking Instructions in this chapter). 18.Make sure to dispose of potentially harmful waste (e.g. fuel, oil, engine coolant, filters, battery) in an envir- onmentally safe manner. Follow all local codes and reg- ulations when recycling or disposing of waste. Safety

Multi Pro 1200/1250 Page1 -- 4 Safety Jacking Instructions CAUTION When changing attachments, tires or performing other service, use appropriate jacks and supports. Make sure machine is parked on a solid, level surface such as a concrete floor. Prior to raising machine, remove any attachments that may interfere with the safe and proper raising of the machine. Always chock or block wheels. Use appropriate jack stands to support the raised machine. If the machine is not properly supported by jack stands, the machine may move or fall, which may result in personal injury. IMPORTANT: Before raising the sprayer, it is rec- ommended to empty the spray tank. If the spray tank is not emptied, consider the extra weight of spray tank contents when choosing appropriate jacks, hoists and jack stands for raising and sup- porting the machine. Jacking the Front End 1. Set parking brake and chock both rear tires to pre- vent the machine from moving. 2. Position jack securely under the A--arms, just to the inside of the front tire (Fig. 1). 3. Jack front of machine off the ground. 4.
