The muffler decreases the noise level and directs the
exhaust gases away from the operator.
WARNING: Mufflers that have catalytic
converters get very hot during operation and
will stay hot for some time after you stop the
product. This also applies at idle speed. If
you touch the product it can result in burns
to the skin. Think about of the risk of fire.

arrestor mesh will cause overheating and
