Air filter
The air filter must be regularly cleaned from dust and dirt in
order to avoid:
• Carburettor malfunctions
• Starting problems
• Engine power reduction
• Unnecessary wear on
the engine parts
• Abnormal fuel consumption
Clean the air filter daily or
more often if the air is
exceptionally dusty in the
working area.
• The air filter is removed
after lifting off the cover.
When reassembling, make
sure that the filter is tight
against the filter holder.
Clean the filter by brushing
or shaking it.
• A more thorough cleaning
of the filter is obtained by
washing it in water and
soap.
MAINTENANCE
An air filter, which is used for some time, cannot be cleaned
completely. Therefore it must be replaced by a new one, with
regular intervals.
IMPORTANT! A damaged air filter must always be replaced.

Spark plug
The spark plug condition is
influenced by:
• An incorrect
carburettor setting.
• Wrong fuel mixture (too
much oil in the gasoline).
• A dirty air filter.
These factors cause deposits
on the spark plug electrodes,
which may result in
malfunction and starting
difficulties.
• If the engine is low on
power, difficult to start or
runs poorly at idling
speed, always check the
spark plug first. If the
spark plug is dirty, clean it
and check the electrode
gap. Readjust if necessary.
The correct gap is 0,5 mm
(0,020"). The spark plug
should be replaced after
about a month in operation
or earlier if the electrodes
are badly eroded.
IMPORTANT! Always use the recommended spark plug type.
An incorrect spark plug can severely damage the piston/
cylinder.
Muffler
The muffler is designed in
order to reduce the noise level
and to direct the exhaust
gases away from the operator.
The exhaust gases are hot
and can contain sparks, which
may cause fire if directed
against dry and combustible
material. Some mufflers are
equipped with a special
screen.
If your saw has this type of muffler, you should clean the screen
at least once a week. This is done with a wire brush.
CAUTION! The screen must be replaced, if damaged. The saw
will be overheated, if the screen is clogged. This results in
damage on the cylinder and the piston. Never use a saw with a
clogged or defective muffler.
