Husqvarna 355 Chainsaw Owners Manual

MAINTENANCE
Air filter
Muffler
The air filter must be regularly cleaned from dust and dirt in
order to avoid:
Carburetor 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.
Abnormal fuel consumption
Clean the air filter daily or
more often if the air is
exceptionally dusty in the
working area.
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.
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 muffler fitted with a catalytic converter reduces the concent-
ration of hydrocarbons (HC), oxides of nitrogen (NO) and
aldehydes emitted with exhaust gases. However, it does not cut
down carbon monoxide (CO), which you cannot smell! Do not
run a chain saw in an unventilated area.
A more thorough cleaning of
the filter is obtained by
washing it in water and
soap.
WARNING!
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
