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.
