Although hazard control and accident prevention partially are 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. Review and understand the contents of the Operator’s Manual and Operator’s DVD before starting and operating the vehicle. Become familiar with the controls and know how to stop the vehicle 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 traction pedal is in NEUTRAL and cutting decks are DISENGAGED. 4. Since diesel fuel is highly flammable, handle it carefully: A. Use an approved fuel container. B. Do not remove 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. E. Wipe up any spilled fuel. Safety Page 1 – 2 – Groundsmaster 4000–D/4010–D While Operating 1. Sit on the seat when starting and operating the machine. 2. Before starting the engine: A. Apply the parking brake. B. Make sure traction pedal is in neutral and the PTO switch is OFF (disengaged). C. After engine is started, release parking brake and keep foot off traction pedal. Machine must not move. If movement is evident, the traction pedal linkage is adjusted incorrectly; therefore, shut engine off and adjust until machine does not move when traction pedal is released. 3. Do not run engine in a confined area without adequate ventilation. Exhaust fumes are hazardous and could possibly be deadly. 4. Do not touch engine, muffler or exhaust pipe 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 traction pedal is in neutral. B. Apply the parking brake. C. Disengage cutting decks and wait for blades to stop. D. Stop engine and remove key from switch. E. Toro recommends that anytime the machine is parked (short or long term), the cutting decks should be lowered to the ground. This relieves hydraulic pressure from the lift circuit and eliminates the risk of the cutting decks unexpectedly lowering to the ground. F. Do not park on slopes unless wheels are chocked or blocked. Safety Groundsmaster 4000–D/4010–D Page 1 – 3 – Safety Maintenance and Service 1. Before servicing or making adjustments, lower decks, stop engine, apply parking brake and remove key from the ignition switch. 2. Make sure machine is in safe operating condition by keeping all nuts, bolts and screws tight. 3. Never store the machine or fuel container inside where there is an open flame, such as near a water heater or furnace. 4. Make sure all hydraulic connectors are tight and all hydraulic hoses and lines are in good condition before applying pressure to the system.
