Dust and dirt should be regularly cleaned from the air filter and
the area around the carburettor 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
•
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 its cover and take
out the filter. When
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.

the filter holder. Shake or
brush clean the filter and
the area around the
carburettor.

A more thorough cleaning of
the filter is obtained by
washing it in water and
soap.
Adjustment of the oil pump
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.
The oil pump is adjustable.
Adjustments 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. NOTE! Max 1 1/2
turns.
IMPORTANT! A damaged air filter must always be replaced.

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 (0.02"). 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.
