ARRESTING SCREEN
As your unit is used, carbon deposits build up
on the muffler and spark arresting screen.
For normal homeowner use, the muffler and
spark arresting screen will not require any
service. After 50 hours of use, we recom-
mend that your muffler be serviced or re-
placed by your authorized service dealer.

2. Remove spark plug from cylinder and
discard.
3. Replace with Champion RCJ-6Y spark
