Storage

Engines stored over 30 days need special attention.

1.

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

additive to the gas in the tank. (See parts list.

Single -- use pouches of gas additive are

available from your service dealer.) If you use a

gas additive, run the engine for several minutes

to circulate the additive through the carburetor.

Then, engine and fuel can be stored up to

24 months.

2.

While engine is still warm, change oil.

3.

Remove spark plug and pour about 1/2 oz.

(15 ml) of engine oil into cylinder. Replace spark

plug and crank slowly to distribute oil.

4.

Clean engine of surface debris, chaff or grass.

5.

Store in a clean, dry area. Do not store in same

area as a stove, furnace, water heater, or other

appliance that uses a pilot light or has a device

that can create a spark.

When Transporting Equipment:

Transport with fuel tank EMPTY

or with fuel shut-off valve OFF.

When

storing

gasoline

or

equipment with fuel in tank:

Store away from furnaces,

stoves, water heaters, or other

appliances that have a pilot light

or other ignition source because

they can ignite gasoline vapors.
