• When checking the trimmer to make
sure that it is okay before using it,
check the area around the muffler and
remove any wood chips or leaves which
have attached themselves to the
trimmer. Note that failing to do so could
cause the muffler to become
overheated, and that this in turn could
cause the trimmer to catch on fire.
Always make sure that the muffler is
clean and free of wood chips, leaves,
and other waste before use.

every 25 hours of use for blockage, and
remove any waste which has attached itself
to the trimmer. Note that it is necessary to

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
trimmer.
