STORAGE
Engines stored over 30 days need special attention.
To prevent gum from forming in fuel system or on essential
carburetor parts:
a) if fuel tank contains oxygenated or reformulated gasoline
(gasoline blended with an alcohol or an ether), run engine until
it stops from lack of fuel, or b) if fuel tank contains gasoline,
either run engine until it stops from lack of fuel, or add a
gasoline stabilizer to the gas in the tank.
Note: If stabilizer is used, run the engine for several minutes to
circulate the additive through the carburetor. Then engine and
fuel can be stored.
1. Change oil.
2. Remove spark plug and pour about 15 ml (1/2 oz.) of
engine oil into cylinder. Replace spark plug and crank
slowly to distribute oil.
3. Clean engine of debris.
4. Store in a clean and dry area.
We recommend use of Briggs & Stratton Fuel Stabilizer
available from an Authorized Briggs & Stratton Service Dealer.
WARNING
DO NOT store near a stove, furnace or water
heater which uses a pilot light or any device
that can create a spark.
