to the fuel system. If you have chosen to use a fuel stabilizer
and have not drained the fuel system, follow all safety
instructions and storage precautions in this manual to
prevent the possibility of fire from the ignition of gasoline
fumes. Remember, gasoline fumes can travel to distant
sources of ignition and ignite, causing risk of explosion and
fire.
NOTE: Gasoline, if permitted to stand unused for extended
periods (30 days or more), may develop gummy deposits
which can adversely affect the engine carburetor and cause
engine malfunction. To avoid this condition, add a gasoline
stabilizer to the fuel tank and run the engine a few minutes,
or drain all fuel from the unit before placing it in storage.
