When the cutting edges of the blade be-
come dull, they can be resharpened with
a few strokes of a
fi
le.
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
fi
le. File the lead-
ing edge of each
tooth to a razor
edge. The top
plate of each tooth
should angle
back 30°.
CAUTION!
Gasoline stored in the carbure-
tor for extended periods can cause
hard starting, and could also lead to
increased service and maintenance
costs.
Blade Sharpening
Long Term Storage
Whenever the unit will not be used for 30
days or longer, use the following proce-
dures to prepare it for storage:
■
Clean external parts thoroughly.
■
Drain all the fuel from the carburetor
and the fuel tank.
IMPORTANT!
All stored fuels should be stabilized with a
fuel stabilizer such as STA-BIL™.
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
fi
le 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.

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 it 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 and reas-
semble the element.
■
Store the machine in a clean, dust-free
area.
