decreases the noise level and identifies
the exhaust gases from the operator. The
exhaust gases are hot and can contain
sparks.
CAUTION: The spark arrester screen
must be replaced if it is damaged. Do not
use a product if the spark arrester screen on
the muffler is missing or defective.
CAUTION: If the spark arrester screen
is blocked, the product will be too hot.

piston.

the product.
