MUFFLER
Inspect and replace corroded muffler as it
could create a fire hazard and/or damage.

SPARK ARRESTOR

Your muffler is equipped with a special spark
arrestor screen which restricts the flow of hot
particles out of the muffler. Hot particles my
cause fire if they contact dry and combus-
tible material. Never operate this equipment
without the spark arrestor in place.
The spark arrestor screen should be cleaned
annually by removing the arrestor from the
engine and brushing it with a wire brush. A
blocked screen may cause the engine to
run hot and lead to engine failure.
TO REMOVE THE SPARK ARRESTOR:
Using a 1/4" wrench or nut driver remove
the (1) screw that retains the arrestor to
the muffler. Slide arrestor screen out of
the muffler exhaust tube.
Inspect the screen for any plugging or
damage. If the screen is plugged, brush
with a stiff wire brush. A damaged arrestor
should be replaced.
Installation is the reverse of removal,
tighten screw to 24 in-lbs (3.7 Nm). Do
not overtighten.
