Long Term Storage

Remove the spark plug and pour about

1/4 ounce of -cycle mixing oil into the

cylinder through the spark plug hole.

Slowly pull the recoil starter or 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.

Whenever the unit will not be used for 0

days or longer, use the following proce-

dures to prepare it for storage:

Clean external parts thoroughly.

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.

Remove the remaining fuel from the fuel

lines and carburetor.

1. Prime the primer bulb until no more

fuel is passing through.

. Start and run the engine until it stops

running.

. Repeat steps 1 and until the engine

will no longer start.

CAUTION!
Gasoline stored in the carburetor for ex-
tended periods can cause hard starting
and could also lead to increased service
and maintenance cost.
