MAINTENANCE
Air lter
The air lter must be regularly cleaned to remove dust and dirt
in order to avoid:
Carburettor malfunctions
Starting problems
Loss of engine power
Unnecessary wear to engine parts
Excessive fuel consumption.
Clean the air lter daily, or more often in demanding
conditions.
Remove the air lter after taking off the air lter cover.
When retting make sure that the air lter seals tightly
against the lter holder. Clean the lter by brushing or
shaking it.
The lter can be cleaned more thoroughly by washing it in
water and detergent.
An air lter that has been in use for a long time cannot be
cleaned completely. The lter must therefore be replaced with
a new one at regular intervals. A damaged air lter must
always be replaced.
A HUSQVARNA chain saw can be equipped with different
types of air lter according to working conditions, weather,
season, etc. Contact your dealer for advice.
Spark plug
The spark plug condition is inuenced by:
Incorrect carburettor adjustment.
Wrong fuel mixture (too much oil).
A dirty air lter.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
difculties.
If the machine is low on power, difcult to start or runs
poorly at idle speed: always check the spark plug rst
before taking any further action. If the spark plug is dirty,
clean it and check that the electrode gap is 0.5 mm
(0,020"). The spark plug should be replaced after about a
month in operation or earlier if necessary.
CAUTION! Always use the recommended spark plug type!
Use of the wrong spark plug can damage the piston/cylinder.
Mufer
The mufer is designed 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 re
if directed against dry and combustible material.
Some mufers are equipped with a special spark arrestor
mesh. If your machine has this type of mufer, you should
clean the mesh at least once a week. This is best done with a
wire brush.
CAUTION! The mesh must be replaced if it is damaged. If the
mesh is blocked the machine will overheat and this will cause
damage to the cylinder and piston. Never use a machine with
a mufer that is in poor condition.
