IMPORTANT SAFETY PRECAUTIONS This symbol is used to call attention to safety precautions that should be followed by the operator to avoid accidents. When you see this symbol, carefully read the message that follows and heed its advice. Failure tocomply with safety precautions could result in serious bodily injury. In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, prudence and proper training of personnel in the operation, transport,maintenance and storage of equipment. Lack of attention to safety can result in accident, per sonal injury,reduction of efficiency and worst of all—loss of life. Watch for safety hazards and correct defi- ciencies promptly. Use the following safety precautions as a general guide to safe operations when using thismachine. Additional safety precautions are used throughout this manual for specific operating and maintenance procedures. Read this manual and review the safety precautions often until you know the limitations. ACCIDENT PATTERNS TO AVOID 1. CONTACT WITH THE ROTATING BLADE - This accident usually happens when the operator is clearing the discharge chute of grass, (especially when the grass is wet), or when the operator adjusts the machine without turning it off and waiting for the blades to completely stop. 2. PROPELLED OBJECTS - Sticks, rocks, wires, and other objects can be propelled out through the discharge chute or from under the mower housing. Avoid discharging toward persons and against walls or obstructions. Material may ricochet toward operator. 3. GRASS DISCHARGE CHUTE - The mower shall not be operated without the grass discharge chute in its lowered position. Do not mow without grass discharge chute or grass catcher in place. 4. OVERTURNING - This happens when riding mowers are used on steep slopes, embankments or hills. The operator in these cases can come in contact with blades or sustain injuries during a fall. 5. MOWER RUNNING OVER THE VICTIM - This usually happens when a riding mower is driven in reverse. The accident victims are most often young children whom, unseen by the operator of the mower, were in the area being mowed. Before and while backing, look behind and down for small chil dren.Be alert and turn machine off if a child enters the area. WE SHARE YOUR DESIRE TO PROTECT YOURSELF, YOUR FAMILY, YOUR FRIENDS AND YOUR NEIGHBORS FROM ACCIDENTAL INJURY. OBSERVING AND ENFORCING THE FOLLOWING GUIDE LINES WILL HELP TO INSURE THE SAFETY OF EVERYONE. SAFETY INSTRUCTIONS AND RECOMMENDATIONS 1. PEOPLE WHO OPERATE, SERVICE, OR ARE OTHERWISE ASSOCIATED with the Zero Turn Mower should be trained in its proper use and warned of its dangers. Before operating, adjusting, or servicing the Zero Turn Mower they should read and understand this entire manual and the engine manual. 2. Do not operate machine while under the influence of alcohol or drugs. 3. A large percentage of riding mower-related injuries data indicates operators age 60 years and above are involved in these accidents. Protect yourself and others from serious injury. Evaluate your ability for a safe riding mower operation. 4. AVOID CONTACT WITH MOVING PARTS. Keep hands and feet from under mowing deck and away from blades at all times. Turn engine (motor) off if you must unclog the chute. 5

5. AVOID HILLS AND SLOPES. Use EXTREME caution when mowing and/or turning on slopes as loss of traction and/or tip-over could occur. Drive slower on slopes. DO NOT mow slopes greater than 15 degrees. Watch for ditches, holes, rocks, dips and rises, which change the operating angle. Keep away from drop-offs and steep banks. Avoid sudden starts when mowing uphill - mower may tip backwards. Loss of traction may occur going downhill - weight transfer to the front wheels may cause drive wheels to slip and cause loss of braking. DO NOT mow slopes when grass is wet - slippery conditions affect steering and reduce traction and braking. The operator is responsible for safe opera tion on slopes. 6. DISENGAGE POWER TO MOWER BEFORE BACKING UP. Do not mow in reverse unless absolutely necessary and then only after turning around and observing the entire area behind the mower. Go slowly. Most “running over victim” accidents occur in reverse. 7. BEGINNING OPERATORS SHOULD LEARN HOW TO STEER the Zero Turn Mower before attempting to mow. Start with slow engine speed and drive without the blades engaged in open area until comfortable with the machine. 8. KNOW HOW TO STOP QUICKLY. Know the location and operation of every control, especially how to brake and how to disengage the mower blades. 9. DO NOT MOVE THE CONTROL LEVERS from forward position to reverse position rapidly. The speed and/or direction of travel is affected instantly by movement of the Control Levers. 10. DO NOT ALLOW CHILDREN TO OPERATE MOWER. Do not allow others who have not had instructions to operate mower. 11. ALWAYS TURN ENGINE OFF AND REMOVE KEY before leaving mower to prevent children and inexperienced operators from starting the engine. Never leave the mower unattended with engine running. Always wait for all moving parts and all sounds to stop before leaving operator’s seat. Always set the parking brake on an unattended mower. 12. WEAR STURDY, ROUGH-SOLED WORK SHOES AND CLOSE-FITTING SLACKS AND SHIRTS. Never operate mower in bare feet, sandals or sneakers. 13. WEAR PERSONAL PROTECTIVE EQUIPMENT such as, but not limited to, protection for eyes, ears, feet,hands and head when operating or repairing equipment. Do not wear loose clothing or jewelry that may catch on equipment moving parts. 14. NEVER CARRY PASSENGERS. 15. KNOW THE AREA YOU ARE TO MOW. Watch for hidden dangers such as rocks, roots, sticks, holes, bumps, and drop-offs, etc. Before mowing, pick up all debris in area to be mowed. Sharp and hard objects can be propelled at a high speed and can act like shrapnel. Walk through tall grass BEFORE MOWING to make sure there are no hidden dangers. Mow higher than desired in tall grass to expose any hidden objects and/or obstacles, clean the area, and then mow to the desired height. 16. BE SURE THE AREA IS CLEAR of other people before mowing. Stop machine if anyone enters the area. 17. Use extreme care when approaching blind corners, shrubs, trees, or other objects that may block your view of a child. 18. NEVER REFUEL A MOWER INDOORS. Allow the engine time to cool before refueling. Unseen vapors may be ignited by a spark. Always clean up spilled gasoline. Never run the engine indoors in a garage or any other closed building. Allow engine to cool before storing in any enclosure. The engine exhaust and gasoline fumes are dangerous. 19. NEVER REMOVE THE FUEL CAP or add gasoline to a running or hot engine or an engine that has not been allowed to cool for several minutes after running. Always make sure the gas cap is in place. 20. DO NOT SMOKE AROUND THE MOWER or the gasoline storage container. Gasoline fumes can easily ignite. 6

21. Use only an approved gasoline container. 22. Avoid fire from static sparks. Never fill gasoline containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place fuel containers on the ground away from your vehicle before filling. 23 Avoid fire from static sparks. Remove mower from truck bed or trailer and refuel it on the ground. Only use an approved gasoline container and not the gasoline dispenser to refuel when the mower remains on trailer or truckbed. 24. Avoid fire from static sparks. During refueling, keep nozzle in contact with fuel tank or fuel container opening at all times. Avoid over filling, do not use nozzle lock-open device. 25. KEEP GASOLINE IN A WELL-VENTILATED AREA away from your living quarters and in tightly capped safety cans. Never store mower with gasoline in the tank inside a building where fumes may reach open flame or spark. 26. DISENGAGE BLADES, STOP ENGINE, ENGAGE PARKING BRAKE, DISCONNECT BATTERY AND REMOVE IGNITION KEYbefore any servicing. Be sure all moving parts and all sounds have stopped. Let engine cool and disconnect the spark plugs so the engine cannot start by accident. 27. KEEP ALL NUTS, BOLTS, AND SCREWS TIGHT to be sure equipment is in safe working condition,especially blade bolts. 28. VEHICLE SHOULD BE STOPPED AND INSPECTED FOR DAMAGE after striking a foreign object and the damage should be repaired before restarting and operating the equipment. Stop immediately and check for damage or loose parts if mower should start vibrating. 29. DISENGAGE BLADES BEFORE DRIVING ACROSS WALKS or projecting objects. 30. KEEP SAFETY DEVICES AND GUARDS IN PLACE. If any of the safety switches become inoperable, have them repaired immediately. 31. DO NOT STEP OR STAND ON THE MOWER HOUSING.
