Long Term Storage

Whenever the unit will not be used for 30 days or longer, use the following procedures to prepare it for storage:

nClean external parts thoroughly.

nDrain 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.

CAUTION!

Gasoline stored in the carburetor for extended periods can cause hard starting and could also lead

to increased service and maintenance cost.

nRemove the remaining fuel from the fuel lines and carburetor.

1.Prime the primer bulb until no more fuel is passing through.

2.Start and run the engine until it stops running.

3.Repeat steps 1 and 2 until the engine will no longer start.

nRemove 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.

nBefore storing the unit, repair or replace any worn or damaged parts.

nRemove the air cleaner element from the carburetor and clean it thoroughly with soap and water. Let dry and reassemble the element.

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

Blade Sharpening

When the cutting edges of the blade be- come dull, they can be resharpened with a few strokes of a file.

In order to keep the blade in balance, all cutting edges must be sharpened equally.

Shindaiwa Tornado™ Blade

To sharpen the cutters on a Shindaiwa Tor- nado Blade, use a 7/32-inch round file. File the leading edge of each tooth to a razor edge. The top plate of each tooth should angle back 30°.
