NOTE:
Fuel stabilizer
is an acceptable
alternative
in minimizing
the formation
of
fuel gum deposits
during
storage.
Add
stabilizer
to gasoline
in fuel tank or stor-
age container.
Always
follow the mix ratio
found
on stabilizer
container.
Run engine
at least 10 minutes
after adding
stabilizer
to allow the stabilizer
to reach
the car-
buretor.
Do not empty
the gas tank and
carburetor
if using fuel stabilizer.

store your unit indoors
and
cover it to protect
it from dust and dirt.
