screen.
4. Clean the spark arrestor screen if it is blocked or
replace it if it is damaged.
CAUTION:
The spark arrestor screen
must be replaced if it is damaged. Do not
use a product without, or with a broken,
spark arrestor screen if you must have a

is frequently blocked it can be a sign that the
performance of the catalytic converter is
decreased. Turn to your servicing dealer to
examine the muffler. A blocked spark
arrestor screen will cause overheating and
result in damage to the cylinder and piston.
