the Chain Sprocket
: Remove the chain sprocket cover,
chain and guide bar.
Replace the chain sprocket:
a
– after using two Oilomatic chains or
sooner
– if the wear marks (dimension a) on
the sprocket are deeper than
0.5 mm – the life of the chain would
otherwise be reduced. Use
reference gauge (special
accessory) to check the depth of the
wear marks.
The service life of the chain
sprocket is prolonged if it is used
with two chains in rotation.
Use only original STIHL replacement

Maintaining and Sharpening
Saw Chain
Correctly sharpened chain
A properly sharpened chain slices
through wood effortlessly and requires
very little feed pressure.
Do not work with a dull or damaged saw
chain as it will increase the physical
effort required, cause higher vibrations,
produce unsatisfactory results and a
higher rate of wear.
: Clean the chain.
: Check the chain for cracks in the
links and damaged rivets.
: Replace any damaged or worn parts
of the chain and match the new
parts to the shape and size of the
original parts by filing back as
necessary.
It is necessary to comply with the
angles and dimensions specified
below. If the saw chain is
incorrectly sharpened – especially
if the depth gauges are too low –
there is an increased risk of
kickback and resulting injury!
