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 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°.
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.
