WARNING; Experience indicates that alcohol blended fuels
icalled 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, the fuel system should be emptied
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. See Storage Instructions
for additional information.
Never use engine or carburetor cleaner products in the fuel
tank or permanent damage may occur,
CAUTION:
• When preparing fuel mixture, mix only the amount
needed for the job you are to do Do not use fuel mixture
that has been stored longer than two (2) months. Fuel
mixture stored lortger than this will cause hard starting
and poor performance, if fuel mix has been stored
longer than this time it should be removed and filled
with a fresh mixture.
• Use only a good grade of regular gasoline,
0 Use only a reputable brand of 2-cycle, air cooled engine
oil. Sears Chain Saw Oil is especially suited to this
