WARNING

You must read, understand and comply with all safety and operating instructions in this manual before attempting to set-up and operate your snowthrower.

Failure to comply with all safety and operating instructions can result in loss of machine control, serious personal injury to you and /or bystanders, and risk of equipment and property damage. The triangle in the text signifies important cautions or warnings which must be followed.

WARNING

Engine exhaust from this product contains chemicals known, in certain quantities, to cause cancer, birth defects, or other reproductive harm.

Safety Rules

GENERAL

• Read the Operator’s Manual carefully. Be thoroughly familiar with all controls and proper equipment use.

• Never allow children to operate the machine. Do not allow adults to operate it without proper instruction.

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

• Never discharge material toward any person or pet.

• Make sure:

a. snowthrower is in good operating condition; b. all safety devices and shields are in place and

working;

c. all adjustments are correct.

PREPARATION

• Never attempt to make any adjustment while engine is running.

• Thoroughly inspect the area where the snowthrower is to be used and remove all objects such as door mats, sleds, boards, wires and sticks.

• Disengage all clutches (release Drive and Auger Control levers) before starting engine.

• Do not operate snowthrower without wearing proper winter clothing. Wear footwear which improves footing on slippery surfaces.

• Do not wear long scarves or loose clothing that could become entangled in moving parts.

• Adjust Skid Shoe height to clear gravel or crushed rock surface.

• Handle gasoline with care - it is highly flammable.

a. Use approved gasoline container. b. Never remove the fuel tank cap or add gasoline to

a running or hot engine. c. Never fill the fuel tank indoors. d. Wipe up spilled gasoline.

• Do not run engine indoors. Exhaust fumes are deadly.

WARNING

This unit is a “two-stage” snowthrower. The first stage is the auger, which feeds the snow

back into the impeller housing. The second stage is the impeller, which throws the snow out the discharge chute. If bodily contact is made with the auger or impeller when they are rotating, severe personal injury will occur.

To avoid injury, keep others and yourself away from the auger and the discharge chute whenever the engine is running. Read and follow all of the safety rules and warnings in this manual.

WARNING

To avoid serious injury, do not put your hands into the auger housing or discharge chute. If auger stalls or chute becomes plugged, use the following procedure to remove objects or clear the chute:

1. Release both the Drive and Auger Control levers.

2. Shut off the engine.

3. Remove the Engine Key.

4. Wait for moving parts to stop.

5. Disconnect spark plug wire.

6. Use a narrow board to remove foreign objects and clear the chute or auger. Never put your hands into the auger or discharge chute.

Safety Rules

OPERATION

• Keep hands and feet away from rotating parts. Keep clear of discharge opening at all times.

• Always clear snow up and down the face of slopes, never across the face. Use extreme caution when changing direction on slopes. Do not attempt to clear slopes over 17.7% (10o)

• Use extreme caution when operating on or crossing gravel drives, walks or roads. Stay alert for hidden hazards and traffic.

• Be especially careful not to touch snowthrower parts which might be hot from operation. Allow such parts to cool before attempting to maintain, adjust or service.

• If unit starts to vibrate abnormally, disengage drives and stop the engine. Check immediately for the cause. Vibration is generally a warning of trouble.

• Before leaving operator’s position for any reason:

- shut off engine,

- remove the Engine Key and

- wait for all moving parts to stop.

• Before cleaning, repairing or inspecting the unit, make certain all moving parts have stopped. Remove the key and then disconnect the spark plug wire to prevent accidental starting.

• Always use a grounded, 3-wire plug receptacle for electric starting.

• Adjust snow discharge angle for safe flow when operating near glass enclosures, automobiles, window wells, dropoffs, etc.

• Do not overload machine capacity by clearing snow at too fast a ground speed.

• Never operate machine at high transport speeds on slippery surfaces. Use care when backing up.

• Disengage Auger Control when transporting or not in use.

• Never operate the snowthrower without good visibility or light. Always be sure of your footing.

• Do not change the engine governor settings or overspeed the engine.

• Never direct the discharge chute at bystanders; nor allow anyone in front of the unit while it is operational.

• Never operate this machine without all of the proper guards or other safety protective devices in place.

MAINTENANCE & STORAGE

• Keep all nuts, bolts and screws tight to ensure that the equipment is in safe operating condition.

• Never store equipment with gasoline in the tank in a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure.

• Always refer to the Operator’s Manual for important details if snowthrower is to be stored for an extended period.

• Run auger drive a few seconds after completion of throwing snow to help clear out snow and prevent icing and freeze-up on unit.

SAFETY DECALS

Safety warning decals are placed at strategic locations on the snowthrower as a constant reminder to the operator of the most important safety precautions. All warning, caution and instructional messages on your snowthrower should be carefully read and obeyed. If any of these decals are lost or damaged, replace them at once. They can be purchased from your local dealer.

WARNING

• Read Owner’s Manual before operating unit.

• Never allow children to operate snowthrower.

• Always direct discharge chute so as to avoid injury to persons—or damage to property

• Stop engine and disconnect spark plug wire before removing debris or servicing unit.

• Keep all shields and guards in place while running.
