MAINTENANCE
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.
