N Flip the bar – after each sharpening
and each time the chain is changed
– to avoid uneven wear, especially
at the sprocket nose and on the
bottom
N Periodically clean the oil inlet
hole (1), oil outlet channel (2) and
bar groove (3)
N Measure groove depth – using the
measuring tool on the file gauge
(special accessory) – in the area
with the greatest wear
If the groove is not at least this deep:
N Replace guide bar
Otherwise the drive links will grind
against the base of the groove – the
bottoms of the cutters and the tie straps
will not lie against the bar.
The air filter system can be adapted to
different operating conditions by the
insertion of different air filters.
Retrofitting is simple.

conditions of use - such as powder
snow or drift snow. Rather
unsuitable in very dusty conditions.
When dry, STIHL filters attain a long
service life.
