INSPECTION Inspect the entire
■
blower and tubes for damage,
including loose or missing compo-
nents, and repair as necessary.
SPARK PLUG Replace the spark
■
plug with a NGK CMR5H (or equiva-
lent), gapped to 0.6 mm (0.024”).
FUEL FILTER Use a hooked wire to
■
extract the fuel filter from inside the
fuel tank. See Figure 21.
(more frequently if reduced perfor-
mance is noted)
Inspect the filter element for signs
■
of contamination from debris. A
contaminated fuel filter should be
replaced with a new Shindaiwa
replacement element. Before rein-
stalling the filter, inspect the con-
dition of the fuel line. If you note
damage or deterioration, the blower
should be removed from service
until it can be inspected by a Shin-
daiwa-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.
Every 50 Hours
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.

Arrester Screen Cover
Figure 22
Inspect the screen carefully, and 3.
replace any screen that has been
perforated, distorted, or is otherwise
unserviceable.
Press the spark arrester into the
4.
exhaust base.
If carbon accumulation in the muffler
or cylinder is severe, or if you do not
notice an improvement in performance
after servicing, have the unit inspected
by an authorized servicing Shindaiwa
dealer.
Spark Arrester
Hard starting or a gradual loss of per-
formance can be caused by carbon
deposits lodged in the spark arrester
screen. For maximum performance, the
spark arrester screen should be periodi-
cally cleaned as follows:
Remove engine cover to expose 1.
muffler. Remove the spark arrester
from the muffler. The arrester is
press-fit in place; there are three
screws to remove.
Use a plastic scraper or wire brush
2.
to remove carbon deposits from
the arrester screen and wipe clean
exhaust base.
WARNING!
Never operate this blower
with a damaged or missing muffler
or spark arrester! Operating with
missing or damaged exhaust compo-
nents is a fire hazard, and can also
damage your hearing!
