Never store engine indoors or in enclosed poorly venti-
lated areas with fuel in tank, where fuel fumes may reach an
open flame, spark or pilot light, as on a furnace, water heater,
clothes dryer or other gas appliance.
If engine is to be unused for 30 days or more, prepare as
follows:
Remove all gasoline from carburetor and fuel tank to
prevent gum deposits from forming on these parts and
causing possible malfunction of engine. Drain fuel outdoors,
into an approved container, away from open flame. Be sure
engine is cool. Do not smoke. Run engine until fuel tank is
empty and engine runs out of gasoline.
NOTE: Fuel stabilizer (such as Sta-Bil) is an acceptable alternative in minimizing
the formation of fuel gum deposits during storage. Add stabilizer to gasoline in
fuel tank or storage container. Always follow mix ratio found on stabilizer
container. Run engine at least 10 min. after adding stabilizer to allow it to reach
the carburetor.
