OPERATION

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 (minimum 87 AKI 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

1.Move the snowthrower to a level surface.

2.Clean around the dipstick (Figure 9).

NOTE: Dipstick location may vary depending on engine type.

3.Remove either side mounted filler cap dipstick or high oil fill dipstick and wipe it clean.

4.Insert the dipstick into the filler neck and turn clockwise until fully seated. Then remove the dipstick by turning it counter-clockwise.

5.Fill oil to "FULL" on dipstick with the recommended oil.

6.Securely screw in the oil filler cap/dipstick.

NOTE: Running the engine with a low oil level can cause engine damage. Always check the engine oil before start up.

NOTE: Running the engine with too much oil may cause engine damage and excess smoke in the exhaust. Always check the engine oil level before start up.
