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.
•
Abnormal fuel consumption
Clean the air filter daily or
more often if the air is
exceptionally dusty in the
working area.
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.
•
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.
Adjusting the oil pump
IMPORTANT! A damaged air
filter must always be
replaced.
The oil pump can be adjusted
to give four different oil flow
rates. To adjust the flow rate,
first remove the chain, bar,
clutch cover, centrifugal clutch
and the clutch drum. Using a
screwdriver, adjust the oil flow
rate by turning the adjuster
screw one way or the other.
The projection on the screw
should point towards the
chosen setting. The diagram
shows the setting for flow rate
2.
Spark plug
0,5 mm
The spark plug condition is
influenced by:
•
•
•
An incorrect carburetor
setting.
Wrong fuel mixture (too
much oil in the gasoline).
A dirty air filter.
Recommended settings:
18"
20"
bars
bars and longer Setting 3-4
Setting 2
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.
NOTE! Do not carry out this adjustment with the engine
running!
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.
