Long Term Storage

n

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.

n

Before storing the unit, repair or replace

any worn or damaged parts.

n

Remove the air cleaner element from the

carburetor and clean it thoroughly with

soap and water. Let dry and reassemble

the element.

n

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

Whenever the unit will not be used for

30 days or longer, use the following

procedures to prepare it for storage:
n

Clean external parts thoroughly.

n

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.

CAUTION!
Gasoline stored in the carburetor

for extended periods can cause hard

starting and could also lead

to increased service and maintenance

cost.

Blade Sharpening

When the cutting edges of the blade

become 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

Tornado 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°.

WARNING!

Sharpen only the cutting teeth of a

blade. DO NOT alter the contour of

the blade in any way.

Multiple-tooth Circular Blade

Use a round file to maintain a radius of 0.04

to 0.06" (1 to 1.5 mm) at the base of each

tooth. Cutting edges must be offset equally

on each side.
