If the snow thrower will not be used for 30 days or

longer, or if it is the end of the snow season when the

last possibility of snow is gone, the equipment needs to

be stored properly. Follow storage instructions below to

ensure top performance from the snow thrower for many

more years.

4. Remove the spark plug and pour one (1) ounce

of engine oil through the spark plug hole into the

cylinder. Cover spark plug hole with a rag and crank

the engine several times to distribute the oil. Replace

spark plug.

CAUTION: 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.
