The information in this manual can help you and others avoid injury and product damage. The operator is responsible for operating this product properly and safely. This manual identifies potential hazards and has special safety messages that help you and avoid personal injury and even death. Danger, Warning, and Caution are signal words used to identify the level of hazard. Howerver, regardless of the hazard, be extremely careful. Danger signals an extreme hazard that will cause series injury or death if you do not follow the recommended precautions. Warning signals a hazard that may cause serious injury or death if you do not follow the recommended precautions. Caution signals a hazard that may cause minor or moderate injury if you do not follow the recommended precautions. This manual uses two other words to highlight information. Important call attention to special mechanical information and Note: emphasizes general information worthy of special attention. · Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or their property. All drivers and mechanics should seek and obtain professional and practical instruction. The owner is responsible for training the users. Such instruction should emphasize: · - the need for care and concentration when working with ride-on machines; - the owner/user can prevent and is responsible for accidents or injuries occurring to himself or herself, other people, or property; - control of a ride-on machine sliding on a slope will not be regained by the application of the brake or putting transmission into neutral. Some reasons for loss of control are: insufficient wheel grip, driving too fast, inadequate braking, using a machine that is unsuitable for a task, lack of awareness of the effect of ground conditions (especially slopes), and incorrect load distribution. Preparation · Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Only use accessories and attachments approved by the manufacturer. While mowing, always wear substantial footwear, long trousers, hard hat, safety glasses, and ear protection. Long hair, loose clothing, or jewelry may get tangled in moving parts. Do not operate the equipment when barefoot or wearing open sandals. Thoroughly inspect the area where the equipment is to be used and remove all objects which may be thrown by the machine. Check that operator's presence controls, safety switches, and shields are attached and functioning properly. Do not operate unless they are functioning properly. Warning - Fuel is highly flammable. Take the following precautions: - Store fuel in containers specifically designed for this purpose. - Refuel outdoors only and do not smoke while refuelling. - Add fuel before starting the engine. Never remove the cap of the fuel tank or add fuel while the engine is running or when the engine is hot. - If fuel is spilled, do not attempt to start the engine but move the machine away from the area of spillage and avoid creating any source of ignition until fuel vapors have dissipated. SAFETY This machine meets or exceeds ANSI B71.4-1999 specifications in effect at the time of production. Improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbols: CAUTION, WARNING, and DANGER. Failure to comply with the instruction may result in personal injury or death. · Safe Operating Practices The following instructions are from CEN standard EN 836:1997, ISO standard 5395: 1990, and ANSI B71.4-1999. · Training · · Read the Operator's Manual and other training material carefully. Be familiar with the controls, safety signs, and the proper use of the equipment. Never allow children or people unfamiliar with these instructions to use or service the mower. Local regulations may restrict the age of the operator. Never mow while people, especially children, or pets are nearby. Do not carry passengers. · · · · 4 Operation · · · · Do not operate the engine in a confined space where dangerous carbon monoxide fumes can collect. Operate only in daylight or in good artificial light. Stay alert for holes in the terrain and other hidden hazards. Before attempting to start the engine, disengage all blade attachment clutches, shift into neutral, and engage the parking brake. Only start the engine from the operator's position. Use seat belts if provided. Never operate with the discharge deflector raised, removed, or altered, unless using a grass catcher. Remember there is no such thing as a safe slope. Travel on grass slopes requires particular care. To guard against overturning: - do not stop or start suddenly when going up or downhill. - machine speeds should be kept low on slopes and during tight turns. - stay alert for humps and hollows and other hidden hazards. - never mow across the face of the slope, unless the mower is designed for this purpose. Watch out for traffic when crossing or near roadways. Slow down and use caution when making turns and crossing roads and sidewalks. Stop the blade rotation before crossing surfaces other than grass. Stop reels or deck blades if not mowing. When using any attachments, never direct discharge of material toward bystanders or allow anyone near the machine while in operation. Never operate the machine with damaged guards, shields, or without safety protective devices in place. Be sure all interlocks are attached, adjusted properly, and functioning properly. Do not change the engine governor settings or overspeed the engine. Operating the engine at excessive speed may increase the hazard of personal injury. Disengage drive to attachements when transporting or not in use. Before leaving the operator's position: - stop on level ground; - disengage the power take-off and blade rotation and lower the attachments; - Change into neutral and set the parking brake; - stop the engine and remove the key. I-TRIM ® Stop the engine and disengage drive to attachment - before refuelling; - before removing the grass catchers; - before making height adjustment unless adjustment can be made from the operator's position. - before clearing blockages; - before checking, cleaning or working on the mower; - after striking a foreign opject or if an abnormal vibration occurs. Inspect the mower for damage and make repairs before restarting and operating the equipment. · · · Reduce the throttle setting before stopping engine and, if the engine is provided with a shut-off valve, turn the fuel off at the conclusion of mowing. Keep hands and feet away from cutting units. Look behind and down before backing up to be sure of a clear path. Do not operate the mower under the influence of alcohol or drugs. Use care when loading or unloading the machine into a trailer or truck. Use care when approaching blind corners, shrubs, trees, or other objects that may obscure vision. · · · · · · · Maintenance and Storage · Keep all nuts, bolts and screws tight to be sure the equipment is in safe working condition. Replace all worn or damaged decals. Never store the equipment with fuel in the tank inside a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure. To reduct the fire hazard, keep the engine, silencer, battery compartment and fuel storage area free of grass, leaves, or excessive grease. Park machine on level ground. Never allow untrained personnel to service machine. Check the grass catcher frequently for wear or deterioration. Keep all parts in good working condition and all hardware and hydraulic fittings tightened. If the fuel tank has to be drained, do this outdoors. Shut off fuel while storing or transporting. Do not store 5 fuel near flames. · · · · · · · · · · · · · Keep hands and feet away from the cutting units. · Be careful during adjustment of the machine to prevent entrapment of the fingers between moving blades and fixed parts of the machine Use care when checking blades. Wrap the blade(s) or wear gloves, and use caution when servicing them. Only replace blades. Never straighten or weld them. On multi-reel or blade machines, take care as rotating one blade can cause other blades to rotate. Disengage drives, lower the cutting units, set parking brake and stop engine. Wait for all movement to stop before adjusting, cleaning or repairing. Clean grass and debris from cutting units, drives, mufflers, and engine to help prevent fires. Clean up oil or fuel spillage. Use jack stands to support components when required. Carefully release pressure from components with stored energy. Disconnect battery before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last. Keep hands and feet away from moving parts. If possible, do not make adjustments with the engine running. Charge batteries in an open well ventilated area, away from spark and flames. Unplug charger before connecting or disconnecting from battery. Wear protective clothing and use insulated tools. · Check the safety interlock switches daily for proper operation. If a switch should fail, replace the switch before operating the machine. Using the machine demands attention. To prevent loss of control: - Do not drive close to sand traps, ditches, creeks, or other hazards. - Reduce speed when making sharp turns. Avoid sudden stops and starts. - When near or crossing roads, always yield the right-ofway. - Reduce foward pedal movement when going downhill to keep forward speed slow and to maintain control of the machine. · · · · · · · · Do not touch the engine, muffler, hydraulic components, or exhaust pipe while the engine is running or soon after it has stopped because these areas could be hot enough to cause burns. Make sure all hydraulic line connectors are tight and all hydraulic hoses and lines are in good condition before applying pressure to the system. Keep your body and hands away from pin hole leaks or nozzles that eject hydraulic fluid under high pressure. Use paper or cardboard, not your hands, to search for leaks. Hydraulic fluid escaping under pressure can have sufficient force to penetrate the skin and cause serious injury. Befo ...
