Seasonally (or whenever you
experience hard starting or poor
performance):
WARNING!
Never operate this machine with a
damaged or missing muffler or
spark arrester! Operating with
missing or damaged exhaust
components is a fire hazard, and
may also damage your hearing.
■
Hard starting or a gradual loss of
performance can be caused by
carbon deposits lodged in the
muffler’s spark arrester screen.
Remove the screen from the
muffler with the point of a small
pliers. See Figure 25. Thoroughly
clean the screen with a stiff bristle
brush. A damaged or otherwise
unserviceable screen must be
replaced. Reinstall by gently
tapping the screen in place.

50-Hour Maintenance
Every 50 hours of operation
(more frequently in dusty or dirty
conditions):
Muffler Maintenance
■
If carbon accumulations in the
muffler or cylinder are severe or if
you do not notice an improvement
in performance after servicing,
return the trimmer to your
Shindaiwa dealer for inspection.
■
Use a hooked wire to extract the
fuel filter from inside the fuel tank.
See Figure 24. Inspect the fuel filter
element. If it shows signs of
contamination from debris, replace
it with a genuine Shindaiwa
replacement fuel filter element.
Before reinstalling the filter,
inspect the fuel line. If you discover
damage or deterioration, the unit
should be removed from service
until it can be inspected by a
Shindaiwa-trained service techni-
cian.
MAINTENANCE
CAUTION!
Make sure you do not pierce the
fuel line with the end of the
hooked wire. The line is delicate
and can be damaged easily.
