turn more with a socket wrench.
TIGHTENING TORQUE: 9.8~11.8 N.m
■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.
• Note that failing to do so may result in the
engine catching on fire.
■INTAKE AIR COOLING VENT
• 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. Note that it is necessary to remove the
plug guard shown in Figure in order to be able to
view the upper part of the cylinder.
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.
(1) Intake air cooling vent

8. Maintenance
-------------------------------------------------------------------------------------------------------
