particles escaping from the machine,
never operate the machine without a
spark arresting screen, or with the spark

accumulated debris such as pine
needles, branches or leaves, ensure

properly serviced spark arresting screen
is provided.

check the spark arresting screen in
the muffler.

damaged, mount new plugs.
