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

INTAKE AIR COOLING VENT
WARNING
•
Check the intake air cooling vent and the
area around the cylinder cooling fins after every
25 hours of use for blockage, and remove any
waste which has attached itself to the brush
cutter.
IMPORTANT
•
If waste gets stuck and causes blockage
around the intake air cooling vent or between the
cylinder fins, it may cause the engine to overheat,
and that in turn may cause mechanical failure on
the part of the brush cutter.
