Air filter MAINTENANCE Spark plug The air filter 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. • Remove the air filter after taking off the air filter cover. When refitting make sure that the air filter seals tightly against the filter holder. Clean the filter by brushing or shaking it. The spark plug condition is influenced by: • Incorrect carburetor adjustment. • An incorrect fuel mixture (too much or incorrect type of oil). • A dirty air filter. These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties. If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first 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. The filter can be cleaned more thoroughly by washing it in water and detergent. An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced with a new one at regular intervals. A damaged air filter must always be replaced. A HUSQVARNA chain saw can be equipped with different types of air filters according to working conditions, weather, season, etc. Contact your dealer for advice. Note! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder. Check that the spark plug is fitted with a suppressor. Lubricating the bar tip sprocket Lubricate the bar tip sprocket each time you refuel. Use the special grease gun and a good quality bearing grease. Needle bearing lubrication The clutch drum has a needle bearing on the output shaft. This needle bearing must be lubricated regularly (once a week). CAUTION! Use only high quality bearing grease or engine oil. See instructions under the heading Cutting equipment. 34 - English

always be replaced.
A HUSQVARNA chain saw can be equipped with different

fi
lters according to working conditions, weather,
season, etc. Contact your dealer for advice.
Spark plug
The spark plug condition is in
fl
uenced by:
•
Incorrect carburetor adjustment.
•
An incorrect fuel mixture (too much or incorrect type of
oil).
•
A dirty air
fi
lter.
These factors cause deposits on the spark plug electrodes,
which may result in operating problems and starting
dif
fi
culties.
If the machine is low on power, dif
fi
cult to start or runs poorly
at idle speed: always check the spark plug
fi
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.
Note! Always use the recommended spark plug type! Use of
the wrong spark plug can damage the piston/cylinder. Check
that the spark plug is
fi
tted with a suppressor.
Lubricating the bar tip sprocket
Lubricate the bar tip sprocket each time you refuel. Use the
special grease gun and a good quality bearing grease.
Needle bearing lubrication
The clutch drum has a needle bearing on the output shaft.
This needle bearing must be lubricated regularly (once a
week). CAUTION! Use only high quality bearing grease or
engine oil. See instructions under the heading Cutting
equipment.
