To clean the muffler
WARNING: The muffler gets very hot
during and after operation, also at idle
speed. Risk of fire and burn injuries.
WARNING: A used muffler/spark
arrester and spark arrester mounting
face may contain deposits of combustion
particles on the surfaces that may be
carcinogenic. To avoid skin contact and
inhalation of such particles when cleaning
and/or servicing the spark arrester, make
sure you always:
• wear gloves;
• clean and/or service in a well ventilated
area;
• do not use pressurized air to clean the
spark arrester screen;
• use a steel brush and brush away from
your body when cleaning the spark
arrester.
1. If the muffler on your product has a spark arrester
screen, clean it weekly with a steel brush. Replace
the spark arrester screen if it is damaged.
CAUTION: A blocked spark arrester
screen causes the engine to become too hot
and results in damage to the cylinder and
piston.
CAUTION: If the spark arrester screen
is frequently blocked, let your service agent
examine the muffler.
