 INSPECTION Inspect the entire blower
and tubes for damage, including loose
or missing components, and repair as
necessary.
 SPARK PLUG Replace the spark plug
with a Champion RCJ6Y (or equivalent),
gapped to 0.6mm.
 FUEL FILTER Use a hooked wire to
extract the fuel filter from inside the fuel
tank.
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.
Spark Arrester Maintenance
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.
CAUTION!
Never allow dirt or debris to enter the
cylinder bore! Before removing the
spark plug, thoroughly clean the spark
plug and cylinder head area!
Allow the engine to cool before servic-
ing the spark plug! Cylinder threads
can be damaged by tightening or loos-
ening the spark plug while the engine
is hot!
electrode.
 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.
 COOLING SYSTEM Use a wood or plas-
tic scraper and a soft brush to remove
dirt and debris from the cylinder fins
and crankcase.
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.
2. Use a plastic scraper or wire brush to re-
move carbon deposits from the arrester
screen and exhaust tube.

1. Use the spark plug wrench to remove
the spark plug.
2. Clean and adjust the spark plug gap to
0.6mm. If the plug must be replaced,
use only Champion RCJ6Y or equivalent
type plug of the correct heat range.
3. Install the spark plug finger-tight in the
cylinder head, then tighten it firmly
with the spark plug wrench. If a torque
wrench is available, torque the spark
plug to 16.7 - 18.6 N-m.

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.
