DANGER: Your chi pper-shred der was buil t to be oper ated accord ing to the rul es for safe o peration in

this manual. As with any type of powe r equipme nt, careless ness or error on the pa rt of the operat or can result in serious i njury. This chipper-shr edder is capable of amputa ting fingers and hands and throwing objects. Failure to observe the following safety instructions could result in serious injury or death.

1. GENERAL OPERATION

• 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.

• Your chipper-shredder is a powerful tool, not a plaything. Therefore, exercise extreme caution at all times. Your unit has been designed to perform two jobs; to chip and shred vegetation found in a normal yard. Do not use it for any other purpose.

• Never allow children under age 16 to operate the unit. Children 16 ye ars 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.

• Keep the area of operation clear of all persons, particularly small children and pets. Stop the engine when they are in the vicinity of the unit. Keep work area clean and clear of branches or obstacles which could cause you to stumble or fall.

• When feeding material into this equipment, be extremely c areful that pieces o f metal, roc ks, bottle s, cans or other foreign objects are not included. Personal injury or damage to the machine could result.

• 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. Wear gloves when feeding material in the chipper chute or shredder hopper.

• Always wear safety glasses or safety goggles, during operation and while performing an adjustment or

repair, to protect eyes from foreign objects that may be thrown from the machine.

• Never place your hands, feet, or any part of your body into the shredder hopper, chipper chute, discharge opening, or near any moving part while the engine is running. Keep clear of the discharge opening at all times. If it becomes necessary to push material into the chipper chute or shredder hopper, use a small diameter stick, NOT YOUR HANDS.

• If it is necessary for any reason to unclog the feed intake or discharge openings or to inspect or repair any part of the machine where a moving part can come in contact with your body or clothing, stop the machine, allow it to cool, disconnect the spark plug wire from the spark plug and move it away from the spark plug before attempting to unclog, inspect or repair.

• Do not operate unit while under the influence of alcohol or drugs.

• The machine should only be operated on a level surface. Never operate your unit on a slippery, wet, muddy or icy surface. Keep your work area clean and clear of branches or obstacles which could cause you to stumble and fall. Do not overreach. Maintaining proper footing and balance is essential to preventing accidents.

• Do not allow an accumulation of processed material to build up in the discharge ar ea as this will preve nt proper discharge and can result in kickback from the chipper chute.

• Keep your face and body back from chipper chute to avoid accidental bounce back of any material.

• Do not transport machine while engine is running.

• If the cutting mechanism strikes a foreign object or 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.

• Inspect for damage.

• Repair or replace any damaged parts.

• Check for any loose parts and tighten to assure continued safe operation.

• Never attempt to attach or remove catcher bag when engine is running. Shut the engine off and wait for the impeller to come to a complete stop. The impeller continues to rotate for a few seconds after the engine is shut off. Never place any part of the body in the impeller area until you are sure the impeller has stopped rotating.

• Muffler and engine become hot and can cause a burn. Do not touch.

• Do not allow leaves or other debris to build up on engine's muffler. The debris could ignite and cause a fire.

• Do not attempt to shred or chip material larger than specified in this manual. Personal injury or damage to the machine could result.

• 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.

• Only use accessories approved for this machine by the manufacturer. Read, understand, and follow all instructions provided with the approved accessory.

• If situations occur which are not covered by this manual, use care and good judgment. Contact your dealer for assistance.

• Keep discharge chute deflector, chipper chute door, and all other guards and safety devices in place and operating properly.

• Only operate unit in good daylight. Do not operate unit at night or in dark areas where your vision may be impaired.

2. CHILDREN

Tragic accidents can occur if the operator is not alert to the presence of small children. Children are often attracted to the chipper-shredder and the chipping and shredding activity. N ever as sume t hat chi ldren will remain where you last saw them.

• Keep children out of the work area and under the watchful eye of a responsible adult other than the operator.

• Be alert and turn the unit off if a child enters the area.

• Never allow children under the age of 16 to operate the chipper-shredder.

3. SERVICE

• Use extreme care in handling gasoline and other fuels. They are extremely flammable and the vapors are explosive.

• 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.

• Replace gasoline cap securely and wipe off any spilled gasoline before starting the engine as it may cause a fire or explosion.

• Extinguish all cigarettes, cigars, pipes and other sources of ignition.

• Never refuel unit indoors because flammable vapors will accumulate in the area.

• 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.

• Never run your machine in an enclosed area as the exhaust from the engine contains carbon monoxide, which is an odorless, tasteless and deadly poisonous gas.

• 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.

• Before cleaning, repairing, or inspecting, make certain the impeller and all moving parts have stopped. Disconnect the s park plug wire and keep wire away from spark plug to prevent accidental starting. Do not use flammable solutions to clean air filter.

• Check the blade and engine mounting screws at frequent intervals for proper tightness. Also visually inspect blades for wear and/or damage (e.g., bent, cracked). R eplace with blade s which meet origi nal equipment specifications.

• Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condit ion.

• Never tamper with safety devices. Check their proper operation regularly.

• After striking a foreign object, immediately stop the engine, disconnect the spark plug wire from the spark plug, and thoroughly inspect the unit for any damage. Repair damage before starting and operating unit.

• 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.
