Operation

NOTE: Determine the left and right sides of the machine from the normal operating position.

•Gasoline is extremely flammable and explosive. A fire or explosion from gasoline can burn you and others.

•To prevent a static charge from igniting the gaso- line, place the container and/or snowthrower on the ground before filling, not in a vehicle or on an object.

•Fill the tank outdoors when the engine is cold. Wipe up spills.

•Do not handle gasoline when smoking or around an open flame or sparks.

•Store gasoline in an approved fuel container, out of the reach of children.

•Do not tip the snowthrower with fuel in the fuel tank.

The operation of any snow thrower can result

in foreign objects thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating your snow thrower or performing any adjust-

ments or repairs. We recommend standard safety glasses or a wide vision safety mask worn over spectacles.

IMPORTANT: Know how to operate all controls before adding fuel or attempting to start the engine.

Filling the Fuel Tank

Fill the fuel tank with fresh unleaded gasoline, do not exceed 87 octane rating (Figure 8).

Figure 8

IMPORTANT: Do not add oil to the gasoline.

IMPORTANT: Do not use E85 blended fuels. This engine is not E20/E30/E85 compatible. Alternative fuels with high alcohol content can cause hard starting, poor engine performance, and may cause internal engine damage.

NOTE: For best results, purchase only the quantity of gasoline that you expect to use in 30 days. Otherwise, you may add fuel stabilizer to newly purchased gasoline to keep it fresh for up to 6 months.

Checking the Engine Oil Level

NOTE: 10W30 synthetic oil is acceptable for use in cold temperatures.

1.Move the snowthrower to a level surface.

2.Clean around the dipstick (Figure 9).

Hand contact with the rotating auger blades inside the discharge chute is the most common cause of injury associated with snow throwers. Never use your hand to clean out the discharge chute.

To clear the chute:

1.SHUT THE ENGINE OFF!

2.Wait 10 seconds to be sure the auger blades have stopped rotating.

3.Always use a clearing tool at least 15 inches long, not your hands (Figure 19).

Figure 19

Preventing Freeze-up after Use

•Let the engine run for a few minutes to prevent moving parts from freezing. Stop the engine, wait for all mov- ing parts to stop, and remove ice and snow from the snowthrower.

•Clean off any snow and ice from the base of the chute.

•Rotate the discharge chute left and right to free it from any ice buildup.

•With the ignition key in the Off position, pull the recoil starter handle several times or connect the electrical cord to a power source and the snowthrower and push the electric start button once to prevent the recoil starter and/or the electric starter from freezing up.

•In snowy and cold conditions, some controls and mov- ing parts may freeze. Do not use excessive force when trying to operate frozen controls. If you have difficulty operating any control or part, start the engine and let it run for a few minutes.

Operating Tips

The auger blades can throw stones, toys, and other foreign objects and cause serious personal injury to the operator or to bystanders.

•Keep the area to be cleared free of all objects that the auger blades could pick up and throw.

•Keep all children and pets away from the area of operation.

•Do not operate snow thrower if weather condi- tions impair visibility. Throwing snow during a heavy, windy snowstorm can blind you and be hazardous to the safe operation of the snow thrower.

•The best time to remove snow is the early morning. At this time the snow is usually dry and has not been exposed to the direct sun and warming temperatures.

•Slightly overlap each successive path to ensure all snow will be removed.

•Throw snow downwind whenever possible.

•For extremely heavy snow, reduce the width of snow removal by overlapping previous path and moving slowly.

•Keep engine clean and clear of snow during use. This will help air flow and extend engine life.

•After snow-throwing is completed, allow engine to run for a few minutes to melt snow and ice off the engine.

•Clean the entire snow thrower thoroughly after each use and wipe dry so it is ready for next use.

Maintenance

NOTE: Determine the left and right sides of the machine from the normal operating position.

Storage

Storing the Snowthrower

Immediately prepare your snow thrower for storage at the end of the season or if the unit will not be used for 30 days or more.

WARNING: Never store the snow thrower with gasoline in the tank inside a building where fumes may reach an open flame, spark or pilot light as on a furnace, water heater, clothes dryer or gas appliance. Allow the engine to cool before storing in any enclosure.

SNOW THROWER

When snow thrower is to be stored for a period of time, clean it thoroughly, remove all dirt, grease, leaves, etc. Store in a clean, dry area.

1.Clean entire snow thrower after each use.

2.Inspect and replace belts, if necessary (See “Replace- ing the Drive Belt” section of this manual).

3.Be sure that all nuts, bolts, screws, and pins are securely fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary.

4.Touch up all rusted or chipped paint surfaces; sand lightly before painting.

FUEL SYSTEM

IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as carburetor, fuel hose, or tank during storage. Also, alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage.

•Empty the fuel tank by starting the engine and letting it run until the fuel lines and carburetor are empty.

•Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

•Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative in mini- mizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not empty the gas tank and carburetor if using fuel stabilizer.

ENGINE OIL

Drain oil (with engine warm) and replace with clean engine oil. (See “Changing the Engine Oil” section of this manual).

CYLINDER

1.Remove spark plug.

2.Pour one ounce (29 ml) of oil through spark plug hole into cylinder.

3.Pull recoil starter handle slowly a few times to distribute oil.

4.Replace with new spark plug.

OTHER

•Remove safety ignition key; store it in a safe place.

•Do not store gasoline from one season to another.

•Replace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems.

•If possible, store your snow thrower indoors and cover it to protect it from dust and dirt.

•Cover your snow thrower with a suitable protective cover that does not retain moisture. Do not use plastic. Plastic cannot breathe, which allows condensation to form and will cause your snow thrower to rust.

IMPORTANT: Never cover snow thrower while engine/ exhaust area is still warm.
