■ 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 : 70~110 kg·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 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.

■ AIR INLET SCREEN
• Blowing air is taken in from the air inlet
screen. When air flow has dropped
down during operation, stop the engine
and inspect the air inlet screen 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
screen at the air intake of the blower.
Before each use, check that, the screw
(1) is securely tightened and is free
from any damage.
