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
•
Abnormal fuel consumption
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.
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 air filter-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.
Needle bearing maintenance
A more thorough cleaning of
the filter is obtained by
washing it in water and
soap.
A
The clutch drum is equipped
with one of the following chain
sprockets:
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.
•
Spur sprocket (A) (the chain
sprocket is welded on the
drum)
IMPORTANT! A damaged air
filter must always be
replaced.
•
Rim sprocket (B)
(exchangeable)

Both versions have built-in
needle bearing at the drive
shaft, whitch has to be
greased regularly (once a
week).
Spark plug
NOTE! Use only high
quality bearing grease.
The spark plug condition is influenced by:
•
•
•
An incorrect carburettor setting.
Wrong fuel mixture (too much oil in the petrol).
A dirty air filter.
Adjustment of the oil pump
These factors cause deposits on the spark plug electrodes,
which may result in malfunction and starting difficulties.
The oil pump is adjustable. Ad-
justments are made by turning
the screw using a screwdriver
or combination spanner. The
saw is supplied from the factory
set to 1 turn open. Turning the
screw clockwise will reduce the
oil flow and turning the screw
anti-clockwise will increase the
oil flow.
If the engine is low on
0,5 mm
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.
WARNING! The engine must not be running
when making adjustments.
Recommended settings:
IMPORTANT! Always use the
recommended spark plug
type. An incorrect spark plug
can severely damage the
piston/cylinder.
Bar
-15": 1 turn from the closed position.
Bar 15"-18": 2 turns from the closed position.
Bar 18"-24": 3 turns from the closed position.
Bar 24"-
: 4 turns from the closed position.
These recommendations apply to Husqvarna’s chain oil, for
other chain oil increase the oil flow by one step.
