Maintaining and
Sharpening the Saw Chain
3/8
Cutting effortlessly with a correctly
sharpened chain
The angles must be the same on all
cutters. If the angles are uneven: Chain
will run roughly, not in a straight line,
wear quickly and finally break.
A properly sharpened chain slices
through wood effortlessly and requires
very little feed pressure.
The chain pitch (e.g. 3/8") is marked on
the depth gauge end of each cutter.
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.
Use only special saw chain
sharpening files. Other files have the
wrong shape and cut.

Clean the chain.
Select file diameter according to chain
pitch – see table “Sharpening Tools”.
Check the chain for cracks in the
links and damaged rivets.
You must observe certain angles when
resharpening the chain cutter.
As these requirements can be met only
after sufficient and constant practice:
N
Replace any damaged or worn
parts of the chain and match the
new parts to the shape and size of
the original parts.

Use a file holder
A
B
A file holder must be used for manual
resharpening (see table "Sharpening
Tools"). The correct filing angles are
marked on the file holder.
Carbide-tipped saw chains (Duro) are
particularly wear resistant. STIHL
recommends you have your chain
resharpened by a STIHL servicing
dealer.
For checking angles
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

with resulting risk of injury.
Cutter shapes
Use a STIHL filing gauge (special
accessory, see table "Sharpening
Tools"). This is a universal tool for
checking the filing and side plate angles,

Super = Full chisel
