Mufer Maintenance
Hard starting or a gradual loss of perfor-
mance can be caused by carbon deposits
lodged in the muffler’s spark arrester
screen.
n In such cases, performance can usu-
ally be restored by removing the spark
arrester screen and giving it a thorough
cleaning with a stiff bristle brush.
n If carbon deposits are severe or if no
performance improvement is noted,
your unit should be returned to your
Shindaiwa dealer for inspection.
WARNING!
Never operate this unit with a damaged
or missing mufer or spark arrester!
Operating with missing or damaged ex-
haust components is a re hazard and
may also damage your hearing.
n Remove the spark plug and pour about
7 grams of oil into the cylinder through
the spark plug hole. Slowly pull the re-
coil starter 2 or 3 times so oil will evenly
coat the interior of the engine. Reinstall
the spark plug.
Whenever the machine will not be
used for 30 days or longer, use the fol-
lowing procedures to prepare it for storage.
n Clean external parts thoroughly and
apply a light coating of oil to all metal
surfaces.
n 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™.
CAUTION!
Gasoline stored in the carburetor for a
long time will likely cause hard starting
and could lead to increased service
and maintenance costs.

Blade Sharpening
WARNING!
Sharpen only the cutting teeth of a
blade. DO NOT alter the contour of the
blade in any way. In order to keep the
blade in balance, all cutting edges must
be sharpened equally. DO NOT le the
tips of the teeth too sharp.
With the file or a grinder, file a blade as
follows.
Make sure the width
of the 4 sides
are all the same.
The sharpening angle should
be approximately 45°.
Do not le the tips of the blade
too sharp. leave 0.2 ~ 0.5 mm
unsharpened.
The bottom of each tooth must remain
unsharpened. (Blade as viewed from bottom.)
