WHEN YOU SEE THIS SYMBOL— HEED ITS WARNING. WARNING: The Engine Exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. DANGER: Your tiller was built to be operated according to the rules for safe operation in this manual. As with any type of power equipment, carelessness or error on the part of the operator can result in serious injury. This tiller is capable of amputating hands and feet. Failure to observe the following safety instructions could result in serious injury or death. 1. GENERAL OPERATION • Do not place feet or hands on or near the tines when starting the engine or while the engine is running. • Read this operator’s manual carefully in its entirety before attempting to assemble this machine. Read, understand, and follow all instructions on the machine and in the manual(s) before operation. Be completely familiar with the controls and the proper use of the machine before operating it. Keep this manual in a safe place for future and regular reference and for ordering replacement parts. • Never attempt to make depth bar, tine width, cable, handle, or wheel adjustments while the engine is running. • Do not leave the tiller unattended with the engine running. • Your tiller is a powerful tool, not a plaything. Therefore, exercise extreme caution at all times. Your unit has been designed to perform one job: to till soil. Do not use it for any other purpose. • Before attempting to remove rocks, bricks and other objects from tines, stop the engine and be sure the tines have stopped completely. Disconnect the spark plug wire and move it away from the spark plug. • Never allow children under age 14 to operate the unit. Children 14 years and older should only operate the unit under close parental supervision. Only responsible individuals who are familiar with these rules of safe operation should be allowed to use your unit. • If your machine should start making an unusual noise or vibration, immediately stop the engine and allow the machine to come to a complete stop. Disconnect the spark plug wire and move it away from the spark plug. Take the following steps: • Do not operate tiller while under the influence of alcohol or drugs. • Inspect for damage. • Repair or replace any damaged parts. • Keep the area of operation clear of all persons, particularly small children and pets. Stop the engine when they are in the vicinity of your tiller. • Check for any loose parts and tighten to assure continued safe operation. • Wear sturdy, rough-soled work shoes and close fitting slacks and shirt. Shirt and slacks that cover the arms and legs and steel-toed shoes are recommended. Do not wear loose fitting clothes or jewelry and secure hair so it is above shoulder length. They can be caught in moving parts. Never operate a unit in bare feet, sandals or sneakers. • Muffler and engine become hot and can cause a burn. Do not touch. • Keep all shields, guards and safety devices in place and operating properly. • Use caution when tilling near fences, buildings and underground utilities. Rotating tines can cause damage or injury. • Operate tiller only in daylight or good artificial light. • Do not operate engine if air cleaner or cover over carburetor air intake is removed, except for adjustment. Removal of such parts could create a fire hazard. • Do not start tiller unless the shift lever (if provided) is in the neutral (N) position. • Do not allow anyone to stand or walk in front of tiller when starting or running engine. 2 Downloaded from www.manualsdb.com manuals search engine • Replace gasoline cap securely and wipe off any spilled gasoline before starting the engine as it may cause a fire or explosion. • Only use accessories approved for this machine by the manufacturer. Read, understand, and follow all instructions provided with the approved accessory. • Extinguish all cigarettes, cigars, pipes and other sources of ignition. • If situations occur which are not covered by this manual, use care and good judgment. Contact your dealer for assistance. • Never refuel unit indoors because flammable vapors will accumulate in the area. 2. CHILDREN • Never store the machine or fuel container inside where there is an open flame or spark such as a gas hot water heater, space heater, clothes dryer or furnace. • Tragic accidents can occur if the operator is not alert to the presence of small children. Children are often attracted to the tilling activity. Never assume that children will remain where you last saw them. • Never run your machine in an enclosed area as the exhaust from the engine contains carbon monoxide, which is a odorless, tasteless and deadly poisonous gas. • Keep children out of the work area and under the watchful eye of a responsible adult other than the operator. • To reduce fire hazard, keep engine and muffler free of leaves, grass, and other debris build-up. Clean up fuel and oil spillage. Allow unit to cool at least 5 minutes before storing. • Be alert and turn the unit off if a child enters the area. • Never allow children under the age of 14 to operate the tiller. • Before cleaning, repairing, or inspecting, make certain the tines and all moving parts have stopped. Disconnect the spark plug wire and keep wire away from spark plug to prevent accidental starting. Do not use flammable solutions to clean air filter. 3. SERVICE • Use extreme care in handling gasoline and other fuels. They are extremely flammable and the vapors are explosive. • Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition. • Store fuel and oil in approved containers, away from heat and open flame, and out of the reach of children. Check and add fuel before starting the engine. Never remove gas cap or add fuel while the engine is running. Allow engine to cool at least two minutes before refueling. • Never tamper with safety devices. Check their proper operation regularly. • Do not alter or tamper with the engine’s governor setting. The governor controls the maximum safe operating speed of the engine. Overspeeding the engine is dangerous and will cause damage to the engine and to other moving parts of the machine.
