IMPORTANT!
Always exercise care and use your common sense.
Avoid all situations which you consider to be beyond
your capability. If you still feel uncertain about operating
procedures after reading these instructions, you should
consult an expert before continuing. Contact an
authorised service workshop.
Always use genuine parts. For more information, see
the "Technical data" section.
Spark plug
NOTICE! Always use the recommended spark plug
type! Use of the wrong spark plug can damage the
piston/cylinder.
• If the machine is low on power, difficult to start or runs
poorly at idle speed: always check the spark plug first
before taking other steps.
• If the spark plug is dirty, clean it and check that the
electrode gap is 0.5 mm. Replace if necessary.

Air filter
• Remove the air filter cover and take out the 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.
• When reassembling, make sure that the filter
completely seals against the filter holder.
Clean the paper filter
• Clean the filter by knocking the filter against a flat
surface. Never use solvent with petroleum, for
example, kerosene, or compressed air to clean the
filter.
Cleaning the foam plastic filter
• Remove the foam plastic filter. Wash the filter well in
tepid soapy water. After cleaning, rinse the filter well
in clean water. Squeeze out and allow the filter to dry.
NOTE! High pressure compressed air can damage
the foam. After cleaning the filter should be oiled using
engine oil. Wipe away excess oil by pressing a clean
cloth against the filter.
