■ 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 0.024 inch (0.6mm).
■ FUEL FILTER Use a hooked wire to
extract the fuel filter from inside the
fuel tank. See Figure 23.
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
WARNING!
Never operate this blower with a
damaged or missing muffler or spark
arrester! 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. See Figure 24.

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
servicing the spark plug! Cylinder
threads can be damaged by tightening
or loosening the spark plug while the
engine is hot!
■ 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
plastic scraper and a soft brush to
remove dirt and debris from the
cylinder fins and crankcase.

1. Use the spark plug wrench to remove
the spark plug. See Figure 22.
2. Clean and adjust the spark plug gap to
0.024" (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 148–165 inch-pounds.

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.
