FUELING ENGINE
This engine is certified to operate on
unleaded gasoline, Before operation,
gasoline must be mixed with a good
quality 2-cycle air-cooled engine oil.
We recommend Craftsman brand oil.
Blower
Vacuum
BEFORE STARTING ENGINE
WARNING: Be sure to read the fuel
information in the safety rules before
you begin. If you do not understand the
-6-
Mix gasoline and oil at a ratio of 40:!
(A 40:1 ratio is obtained by mixing 3.2
ounces of oil with 1 gallon of unleaded
gasoline). DO NOT USE automotive oil
or boat oil. These oils will cause engine
damage. When mixing fuel, follow
instructions printed on container.
Once oil is added to gasoline, shake
container momentarily to assure that
the fuel is thoroughly mixed. Always
read and follow the safety rules relating
to fuel before fueling your unit°
IMPORTANT
Experience indicates that 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.
To avoid engine problems, empty the
fuel system before storage for 30 days
or longer. Drain the gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh
fuel next season.
Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel
gum deposits during storage. Craftsman brand oil is already blended with
fuel stabilizer. See the STORAGE section for additional information.
