not require adjusting. However, refer to
the Trouble Shooting Section of this

ENGINE STORAGE
If grass deflector shows wear, it should
be replaced.
It _s important to prevent gum deposits
from forming in essential fuel system
parts such as the carburetor, fuel filter,
fuel hose or tank during storage. Also,
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, the fuel
system should be emptied before
storage of 30 days or longer. Follow
these instructions:
To remove gasoline, run the engine
until the tank is empty and the engine
stops.
10
If you do not want to remove gasoline,
a fuel stabilizer (such as Sears
Craftsman fuel stabilizer No. 33500)
may be added to any gasoline left in
the tank to minimize gum deposits and
acids. If the lank is almost empty, mix
stabilizer with fresh gasoline/oil
mixture in a separate container and
add some to the tank.
Always follow instructions on
stabilizer container. Run engine at
least 10 minutes after stabilizer is
added to allow mixture to reach
carburetor. Store trimmer in a safe
place. See warning above.
