■ 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.
•Note that failing to do so may result in
the engine catching on fire.
• Before starting operation, always make
sure to check if the muffler is properly held
by three bolts to the cylinder. (Fastening
Torque : 80~120kg·cm)
• Even if one bolt out of three bolts is loose,
the muffler may get loose during operation
which may result in engine catching on fire.
■ 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 Public Resources Code) to equip
a spark arrester when a gas powered tool
is used in any forest covered, brush
covered, or grass covered unimproved
land.

■ AIR INLET NET
• Blowing air is taken in from the air inlet net.
When air flow has dropped down during
operation, stop the engine and inspect the
air inlet net for blocking by obstacles.
• Note that failure to remove any such
obstacles may result in the engine
becoming overheated and damaged.
•Never use the blower without the net of
the blower. Before each use, check that
the net is attached in place and is free
from any damage.
