MAINTENANCE

Long Term Storage

Whenever the unit will not be used for

30 days or longer, use the following

procedures to prepare it for storage:

Clean external parts thoroughly.

Drain all the fuel from the fuel tank.

To remove the remaining fuel from

the fuel lines and carburetor and with

the fuel drained from the fuel tank.
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.

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 re-

place any worn or damaged parts.

Remove the air cleaner element from

the carburetor and clean it thoroughly

with soap and water. Let dry before

reinstalling 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.

When the blade’s cutting edges

become slightly dull, they can be re-

sharpened with a few strokes of a file.

In order to keep the blade in balance,

all cutting edges must be sharpened

equally.

NOT alter the contour of the blade in
any way.
