CAUTION!
Gasoline stored in the carburetor
for extended periods can cause
hard starting and could also lead
to increased service and mainte-
nance costs.
Blade Sharpening
Long Term Storage
Whenever the machine will not be
used for 30 days or longer
, use the
following procedures to prepare it for
storage:
Clean external parts thoroughly and
apply a light coating of oil to all metal
surfaces.
Drain all the fuel from the carburetor
and the fuel tank.
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. Rein-
stall the spark plug.
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 4 Tooth Blade
To sharpen the cutters on a Shindaiwa
4 tooth blade, use a flat file. File the
leading edge of each tooth to a near
razors edge. The cutting edge should be
maintained at approximately 30° with a
rounded radius at the inside of the cut-
ting edge. See Figure 33.
WARNING!
Sharpen only the cutting teeth
of a blade. DO NOT alter the
profile of the tooth 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.
See Figure 34.

IMPORTANT!
All stored fuels should be stabilized with
a fuel stabilizer such as STA-BIL™.
Before storing the machine, repair or
replace any worn or damaged parts.
Remove the air cleaner element from
the carburetor and clean it thorough-
ly with soap and water, let dry, oil
lightly and reassemble the element.
Store the machine in a clean, dust-
free area.
