The muffler is designed to
dampen the noise level and to
direct the exhaust fumes away
from the user. The exhaust
fumes are hot and can
contain sparks, which can
result in fire if the exhaust
fumes are directed towards a
dry and inflammable mate-
rial. Some mufflers are
equipped with a special spark
arrest screen. If your machine
is fitted with this type of
screen it should be cleaned
regularly. This is done using a

If the machine is low on power, difficult to start or runs
poorly while idling always check the spark plug first.
If the spark plug is dirty, clean it and at the same time check
that the electrode gap is 0.5 mm. The spark plug should be
