MUFFLER
Inspect periodically, the muffler for loose fasteners,
any damage or corrosion. If any sign of exhaust
leakage is found, do not use the blower and have it
repaired immediately.

engine catching on fire.
Before starting operation, always make sure to
check if the muffler is properly held by two bolts (F17

SPARK ARRESTER
The muffler is equipped with a spark arrester to
prevent red hot carbon from flying out of the exhaust
outlet. Periodically inspect and clean as necessary
with a wire brush. In the State of California it is
required by law (Section 4442 of the California Pulic
Resources Code) to equip a spark arrester when a
gas powered tool is used in any forest covered, bush
covered, or grass covered unimproved land.
