THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY. WHEN YOU SEE THIS SYMBOLHEED 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 snow thrower 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. If you violate any of these rules, you may cause serious injury to yourself or others.

1. TRAINING

• Read this operator's manual carefully in its entirety before attempting to assemble or operate this machine. Be completely familiar with the controls and the proper use of this machine before operating it. Keep this manual in a safe place for future and regular reference and for ordering replacement parts.

• Never allow children under 14 years old to operate a snow thrower. Children 14 years old and over should only operate snow thrower under close parental supervision. Only persons well acquainted with these rules of safe operation should be allowed to use your snow thrower.

• No one should operate this unit while intoxicated or while taking medication that impairs the senses or reactions.

• Keep the area of operation clear of all persons, especially small children and pets.

• Exercise caution to avoid slipping or falling, especially when operating in reverse.

1. PREPARATION

• Thoroughly inspect the area where the equipment is to be used and remove all door mats, sleds, boards, wires and other foreign objects.

• Disengage all clutches and shift into neutral before starting engine.

• Do not operate equipment without wearing adequate winter outer garments. Do not wear jewelry, long scarfs or other loose clothing which could become entangled in moving parts. Wear footwear which will improve footing on slippery surfaces.

• Before working with gasoline, extinguish all cigarettes and other sources of ignition. Check the fuel before starting the engine. Gasoline is an extremely flammable fuel. Do not fill the gasoline tank indoors, while the engine is running, or until engine has been allowed to cool at least two minutes. Replace gasoline cap securely and wipe off any spilled gasoline before starting the engine as it may cause a fire or explosion.

• Use a grounded three wire plug-in for all units with electric drive motors or electric starting motors.

• Adjust collector housing height to clear gravel or crushed rock surface.

• Never attempt to make any adjustments while engine is running (except where specifically recommended by manufacturer).

• Let engine and machine adjust to outdoor temperature before starting to clear snow.

• Always wear safety glasses or eye shields during operation or while performing an adjustment or repair, to protect eyes from foreign objects that may be thrown from the machine in any direction.

2. OPERATION

• Do not put hands or feet near or under rotating parts. Keep clear of discharge opening and auger at all times.

• Exercise extreme caution when operating on or crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic. Do not carry passengers.

• After striking a foreign object, stop the engine, remove wire from spark plug, and thoroughly inspect the snow thrower for any damage. Repair the damage before restarting and operating the snow thrower.

• If the snow thrower should start to vibrate abnormally, stop the engine and check immediately for the cause. Vibration is generally a warning of trouble.

• Stop engine whenever you leave the operating position, before unclogging the collector/impeller housing or discharge guide, and making any repairs, adjustments, or inspections. Never place your hand in the discharge or collector openings. Use a stick or wooden broom handle to unclog the discharge opening.

• Take all possible precautions when leaving the unit unattended. Disengage the collector/impeller, shift into neutral, stop the engine, and remove the key.

• When cleaning, repairing, or inspecting, make certain collector/impeller and all moving parts have stopped. Disconnect spark plug wire and keep away from plug to prevent accidental starting.

• Do not run engine indoors, except when starting engine and transporting snow thrower in or out of building. Open doors. Exhaust fumes are dangerous.

• Do not clear snow across the face of slopes. Exercise extreme caution when changing direction on slopes. Do not attempt to clear steep slopes.

• Never operate snow thrower without guards, plates, or other safety protection devices in place.

• Never operate snow thrower near glass enclosure, automobiles, window wells, drop off, etc., without proper adjustments of snow thrower discharge angle. Keep children and pets away.

• Do not overload machine capacity by attempting to clear snow at too fast a rate.

• Never operate the machine at high transport speeds on slippery surfaces. Look behind and use care when backing.

• Never direct discharge at bystanders or allow anyone in front of unit.

• Disengage power to collector/impeller when transporting or not in use.

• Use only attachments and accessories approved by the manufacturer of snow thrower (such as wheel weights, counter weights, cabs, etc.).

• Never operate the snow thrower without good visibility or light. Always be sure of your footing and keep a firm hold on the handles. Walk, never run.

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

3. MAINTENANCE AND STORAGE

• Check shear bolts, engine mounting bolts, etc., at frequent intervals for proper tightness to be sure equipment is in safe working condition.

• Never store the machine with fuel in the fuel tank inside a building where ignition sources are present, such as hot water and space heaters, clothes dryers, and the like. Allow engine to cool before storing in any enclosure.

• Always refer to operator's manual instructions for important details if snow thrower is to be stored for an extended period.

• Run machine a few minutes after throwing snow to prevent freeze up of collector/impeller.

• Check clutch controls periodically to verify they engage and disengage properly and readjust if necessary. Refer to operator's manual for adjustment instructions.

WARNING - YOUR RESPONSIBILITY:

Restrict the use of this power machine to persons

who read, understand and follow the warnings and instructions in this manual and on the machine.
