STORAGE
Adding a Fuel Stabilizer to Extend Fuel Storage Life
Short Term Storage (30-90 days)
If your equipment will not be used for 30-90 days, we recommend the
following to prevent fuel-related problems.
1.Add fuel stabilizer following the manufacturer's instructions.
When adding a fuel stabilizer, fill the fuel tank with fresh gasoline. If
only partially filled, air in the tank will promote fuel deterioration
during storage. If you keep a container of gasoline for refueling, be
sure that it contains only fresh gasoline.
If it takes more than 3 months to use the fuel in your storage
container, we suggest adding a fuel stabilizer to the fuel when you
full the container.
2.After adding a fuel stabilizer, run the engine outdoors for 10 minutes
to be sure that treated gasoline has replaced the untreated gasoline
in the carburetor.
Dry operation will damage the pump seal. Be sure the pump chamber
is filled with water before starting the engine.
3.Stop the engine, and move the fuel valve lever to the OFF position.
4.Remove the pump drain plug, and allow the water to drain from the
pump chamber. Reinstall the drain plug.
