N
Turn the bar over – every time you
sharpen the chain and every time
you replace the chain – this helps
avoid one-sided wear, especially at
the nose and underside of the bar.
N
Regularly clean the oil inlet hole (1),
the oilway (2) and the bar
groove (3).
N
Measure the groove depth – with
the scale on the filing gauge (special
accessory) – in the area used most
for cutting.

Air Filter System

The air filter system can be adapted to
different operating conditions by the
insertion of different air filters.
Retrofitting is simple.

N
Standard filter (1) with wire mesh
(green filter housing) for normal
operating conditions and use in
winter.
N
HD filter (2) (black filter housing)
with felt prefilter for dry, very dusty
operating environments
When dry, STIHL filters (standard and
HD filters) attain a long service life.
N
Always use STIHL filters dry
Fouled air filters will impair engine
performance, increase fuel consumption
and make the machine more difficult to
start.
