WARNING!
Never operate this blower with a dam-
aged or missing muffler or spark arrest
-
er! Operating with missing or damaged
exhaust components is a fire hazard,
and can also damage your hearing!
Hard starting or a gradual loss of perfor-
mance can be caused by carbon deposits
lodged in the spark arrester screen. For
maximum performance, the spark arrester
screen should be periodically cleaned as
follows.

1. Use a needle-nose pliers to remove the
spark arrester from the exhaust tube.
The arrester is press-fit in place; there
are no screws to remove.

INSPECTION Inspect the entire blower
and tubes for damage, including loose
or missing components, and repair as
necessary.
n
SPARK PLUG Replace the spark plug
with a Champion RCJ6Y (or equivalent),
gapped to 0.6 mm.
n
FUEL FILTER Use a hooked wire to
extract the fuel filter from inside the fuel
tank.
(more frequently if reduced
performance is noted)
CAUTION!
Make sure you do not pierce the fuel
line with the end of the hooked wire.
The line is delicate and can be dam-
aged easily.
n
Inspect the filter element for signs of
contamination from debris. A contami-
nated fuel filter should be replaced with
a new Shindaiwa replacement element.
Before reinstalling the filter, inspect the
condition of the fuel line. If you note
damage or deterioration, the blower
should be removed from service until it
can be inspected by a Shindaiwa-trained
service technician.

Long Term Storage
CAUTION!
Gasoline stored in the carburetor for
extended periods can cause hard start-
ing, and could also lead to increased
service and maintenance costs.
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
Shindaiwa One oil with fuel stabilizer is
not used.
To remove the remaining fuel from the
fuel lines and carburetor and with the fuel
drained from the fuel tank.
n
Remove the spark plug and pour
about 7 grams of -cycle mixing oil into
the cylinder through the spark plug
hole. Slowly pull the recoil starter 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 unit and clean it as outlined on
page 10.
n
Store the unit in a clean, dust-free area.
1. Prime the primer bulb until no more fuel
is passing through.
. Start and run the engine until it stops
running.
3. Repeat steps 1 and until the engine will
no longer start.
n
COOLING SYSTEM Use a wood or plas-
tic scraper and a soft brush to remove
dirt and debris from the cylinder fins
and crankcase.
. Use a plastic scraper or wire brush to re-
move carbon deposits from the arrester
screen and exhaust tube.
3. Inspect the screen carefully, and replace
any screen that has been perforated,
distorted, or is otherwise unserviceable.
4. Press the spark arrester into the ex-
haust tube. A soft mallet may be used to
tap the spark arrester home.
If carbon accumulation in the muffler or
cylinder are severe, or if you do not notice
an improvement in performance after
servicing, have the unit inspected by an
authorized servicing Shindaiwa dealer.
