MAINTENANCE
Air filter
Muffler
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
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.
•
Abnormal fuel consumption
Clean the air filter daily or
more often if the air is
exceptionally dusty in the
working area.
•
•
Disassemble the air filter by
removing the cylinder cover
and unscrew the filter.
When reassembling, make
sure that the filter is tight
against the filter holder.
Clean the filter by brushing
or shaking it.
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.
A more thorough cleaning
of the filter is obtained by
washing it in water and
soap.
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.
Needle bearing maintenance
IMPORTANT! A damaged air
filter must always be
replaced.

plug should be replaced after
about a month in operation or
earlier if the electrodes are
badly eroded.
NOTE! Use only high quality

IMPORTANT! Always use the
recommended spark plug
type. An incorrect spark plug
can severely damage the
piston/cylinder.
