Maintaining and
Sharpening the Saw Chain
Cutting effortlessly with a 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
chain as it will increase the physical
effort required, produce unsatisfactory
results and a higher rate of wear.
N
Clean the chain.
N Check the chain for cracks in the
links and damaged rivets.
N Replace any damaged or worn
parts of the chain and match the
new parts to the shape and size of
the original parts.
Carbide-tipped saw chains (Duro) are
particularly wear resistant. STIHL
recommends you have your chain
resharpened by a STIHL servicing
dealer.
It is absolutely essential to comply
with the angles and dimensions
specified below. If the saw chain is
incorrectly sharpened – and in
particular if the depth gauge is set
too low – there is a risk of
increased kickback of the saw,
with resulting risk of injury.
The chain pitch (a) is marked on the
depth gauge end of each cutter.
Mark (a) Chain pitch

Use only special saw chain
sharpening files. Other files have the
wrong shape and cut.
Select file diameter according to chain
pitch – see table "Sharpening Tools".
You must observe certain angles when
resharpening the chain cutter.
