Filling the Engine with Oil

ENGINE

See engine manual.

LUBRICATION

NOTE: SAE 10W30 or SAE 5W30 oil is acceptable for use in cold temperatures if engine is difficult to start.

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil.

Change the oil after every 25 hours of operation or at least once a year if the snow thrower is not used for 25 hours in one year.

Check the crankcase oil level before starting the engine and after each five (5) hours of continuous use. Tighten oil fill cap / dipstick securely each time you check the oil level.

1.Move the snowthrower to a level surface.

2.Clean around the dipstick (Figure 7).

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.

Fill if oil is below “Add” on the

GLSVWLFN

Fill if oil is

below letter

“L” on the

¿OOHU FDS

Figure 7

1.Oil filler cap/dipstick

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.

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 gasoline, place the container and/or snowthrower on the groundbeforefilling,notinavehicleoronanobject.

•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 adjustments 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 9).

Figure 9

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.
