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.

in the engine catching on fire.
• Before starting operation, always make
sure to check if the muffler is properly
held by two bolts (F17 (2)). (Fastening

• Also make sure that the spark arrester
and the diffuser are properly attached
with two bolts (F17 (1)). (Fastening

used in any forest covered, bush
covered, or grass covered unimproved
land.
