Long Term Storage; Blade Sharpening - Shindaiwa T350 Owner's/Operator's Manual

Muffler Maintenance
If the engine becomes hard to start or
has low power, the spark arrester screen
should be inspected and cleaned.
WARNING!
Never operate the unit with a dam-
aged or missing muffler or spark
arrester! Operating with missing or
damaged exhaust components is a
fire hazard and could also damage
your hearing.
1. Remove the 3 socket-head cap screws
retaining the muffler cowl and re-
move the cowl. See Figure 37.
2. Remove the spark arrester screen by
gently prying on the lip at the exhaust
outlet.

Long Term Storage

Whenever the unit will not be used for
30 days or longer, use the following pro-
cedures to prepare it for storage:
 Clean external parts thoroughly.
 Drain all the fuel from the fuel tank.
IMPORTANT!
All stored fuels should be stabilized with
a fuel stabilizer such as
STA-BIL™.
To remove the remaining fuel from the
fuel lines and carburetor and with the
fuel drained from the fuel tank:

Blade Sharpening

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 Tornado™ Blade
To sharpen the cutters on a Shindaiwa
Tornado 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°.

3. Remove the spark arrester screen and
clean with a stiff bristle brush.
IMPORTANT!
If carbon deposits are severe or if no
performance improvement is noted, this
unit should be inspected by an autho-
rized Shindaiwa servicing dealer.
4. Reinstall the spark arrester screen
with a light tap of a mallet to seat.
NOTE:
The screen is held in place by a press
fit on the muffler exhaust outlet.
5. Reinstall the muffler cowl and
tighten the 3 socket-head cap
screws securely.
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.
CAUTION!
Gasoline stored in the carburetor
for extended periods can cause
hard starting, and could also lead to
increased service and maintenance
costs.
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. See Figure 39.

 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.
 Before storing the unit, repair or
replace 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 unit in a clean, dust-free
area.
