Husqvarna Troubleshooting Common Problems for Chainsaw Models

MAINTENANCE

Fitting the starter

•To ﬁt the starter, ﬁrst pull out the starter cord and place the starter in position against the crankcase. Then slowly release the starter cord so that the pulley engages with the pawls.

•Fit and tighten the screws that hold the starter.

Air ﬁlter

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 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.

Spark plug

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 0.020 inch (0.5 mm).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 ﬁtted with a suppressor.
