and dirt in order to avoid:
Loss of engine power.
Unnecessary wear to engine parts
Excessive fuel consumption.
Clean the ﬁlter every 40 hours, or more regularly if
conditions are exceptionally dusty.
Avoid contact with hot surfaces on mufﬂer, cylinder etc.
Contact can result in burns to the skin.
Cleaning the air ﬁlter
Remove the air ﬁlter cover and take out the ﬁlter. Wash it
clean in warm, soapy water.
If the machine is used in dusty conditions the air ﬁlter
should be soaked in oil. See instructions under the
heading Oiling the air ﬁlter.
An air ﬁlter that has been in use for a long time cannot be
cleaned completely. The ﬁlter must therefore be replaced
with a new one at regular intervals. A damaged air ﬁlter
must always be replaced.
Reﬁt the air ﬁlter and air ﬁlter cover.
