Long Term Storage

Whenever the unit will not be used for 30

days or longer, use the following proce-

dures to prepare it for storage:

Clean external parts thoroughly and

apply a light coating of oil to all metal

surfaces.

Drain all the fuel from the fuel tank.

IMPORTANT!

All stored fuels should be stabilized with

a fuel stabilizer such as STA-BIL™, if

oil with fuel stabilizer is not used.

To remove the remaining fuel from the

fuel lines and carburetor and with the fuel

drained from the fuel tank.

Remove the spark plug and pour about

1/4 ounce of 2-cycle mixing oil into the

cylinder through the spark plug hole.

Slowly pull the recoil starter 2 or 3 times

so oil will evenly coat the interior of the

engine. Reinstall the spark plug.

Before storing the unit, repair or replace

any worn or damaged parts.

Remove the air cleaner element from the

carburetor and clean it thoroughly with

soap and water. Let dry and reassemble

the element.

Store the unit in a clean, dust-free area.

CAUTION!
Gasoline stored in the carburetor for

extended periods can cause hard start-

ing, and could also lead to increased

service and maintenance costs.

1. Prime the primer bulb until no more fuel

is passing through.

2. Start and run the engine until stops

running.

3. Repeat steps 1 and 2 until the engine will

no longer start.
