Long Term Storage
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.
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 7/3-inch round file. File
the leading edge of each tooth to a razor
edge. The top plate of each tooth should
angle back 30°.
CAUTION!
Gasoline stored in the carburetor
for extended periods can cause hard
starting and could also lead to increased
service and maintenance cost.
n 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.
3. Repeat steps 1 and until the engine will
no longer start.

WARNING!
Sharpen only the cutting teeth of a
blade. DO NOT alter the contour of
the blade in any way.
n 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 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.
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.
