Spark Arrestor Maintenance - Shindaiwa EB240 Owner's/Operator's Manual

Spark Arrester Maintenance
WARNING!
Never operate the unit with a
damaged or missing muffler
or spark arrester! Operating with
missing or damaged exhaust compo-
nents is a fire hazard and could also
damage your hearing.
Hard starting or a gradual loss of
performance can be caused by
carbon deposits lodged in the spark
arrester screen, muffler or cylinder
exhaust port. For maximum perfor-
mance, the muffler and spark ar-
rester screen should be periodically
cleaned as follows:
1. Remove the spark plug.
CAUTION!
Always replace cover screws in the
same holes as removed! Substitution
or incorrect assembly of engine cover
screws can permanently damage
aluminum castings and plastic compo-
nents!
2. Remove (3) self-tapping screws
and (2) machine screws from the
engine cover, and then gently
move the engine cover aside.
3. Remove the (3) spark arrester
retaining screws, then remove the
spark arrester cover, screen,
gasket, and chamber.
4. Use a plastic scraper or wire brush
to remove carbon deposits from
the arrester screen, chamber,
and cover.
5. Inspect the screen carefully, and
replace any screen that has been
perforated, distorted, or is other-
wise unserviceable.
6. Remove the (2) socket-head cap
screws and (1) Phillips head screw,
then remove the muffle
7. Gently tap the muffler on a wood
surface to dislodge any loose
carbon.
8. Inspect the cylinder exhaust port
for excessive carbon buildup
IMPORTANT!
If carbon deposits are severe or if no
performance improvement is noted, your
EB240 blower should be inspected by an
authorized Shindiawa servicing dealer.
9. Reinstall the muffler in the
reverse order as described in step
6 and securely tighten the (2)
socket- head cap screws and
