Fuel Storage
NEVER store engine with fuel in the
fuel tank inside a building with potential sources of
ignition such as hot water heater, space heater,
clothes dryer, electric motor, etc. Failure to do so
may result in an explosion and result in death or
serious injury.
If engine fuel stored in the gas tank and/or an approved
gas container is to be unused without gasoline stabilizer for more
than 15-30 days, prepare it for short-term/seasonal storage. See
Fuel Treatment later in this section.
If engine fuel is to be stored for more than one season,
without gasoline stabilizer, it will gradually deteriorate. Also, if
it is stored in the engine’s gas tank without gasoline stabilizer it
is likely that your carburetor will have gum deposits, a clogged
fuel system and will VOID YOUR WARRANTY. Prepare the fuel for
extended storage.
Fuel System
To avoid stale fuel and carburetor problems, treat the fuel system
in the following manner:
NOTE: Always follow mix ratio found on the stabilizer container.
Failure to do so may result in equipment damage.
NOTE: It is NOT necessary to drain stabilized gas from carburetor.
Fuel Treatment
Add fuel stabilizer according to Manufacturer’s 1.
instructions.
Run engine at least 10 minutes after adding the stabilizer to 2.
allow it to reach the carburetor.
NEVER store the engine with the fuel in
the fuel tank inside a building with potential sources
of ignition such as a hot water heater, space heater,
clothes dryer, electric motor, etc.
NOTE: Instead of using a fuel preservative/stabilizer, you can
empty the fuel tank as described next in Extended Storage -
Draining the Fuel.
Extended Storage
Draining the Fuel
NOTE: Clean debris from the engine before draining fuel from
the carburetor.
NOTE: If you have prepared your fuel for short-term storage it
is NOT necessary to drain fuel that contains stabilizer from your
carburetor.
To avoid severe injury or death, DO
NOT pour fuel from engine or siphon fuel by mouth.
To prevent serious injury from fuel fires, empty fuel tank 1.
by running engine until it stops from lack of fuel. DO NOT
attempt to pour fuel from engine.
Run the engine while waiting until the remaining fuel is 2.
consumed.
NEVER leave the engine unattended
when it is running and NEVER run the engine in an
enclosed area.
