N Disengage the chain brake: Pull the
hand guard toward the front handle.
N Remove the chain sprocket cover,
chain and guide bar.
Replace the chain sprocket
– after using two saw chains or
sooner
– if the wear marks (arrows) on the
sprocket are deeper than approx.
0.02 in (0.5 mm) since this would
reduce the life of the chain. You can
use a gauge (special accessory) to
check the depth of the wear marks.
It is best to use two saw chains in
rotation with one sprocket.
STIHL recommends the use of original
STIHL sprockets to ensure correct
operation of the chain brake.
Have the chain sprocket replaced by a
servicing dealer. STIHL recommends
that you have servicing and repair work
carried out exclusively by an authorized
STIHL servicing dealer.
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.
The chain pitch (a) is marked on the
depth gauge end of each cutter.
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.

B Side plate angle

Maintaining and
Sharpening the Saw Chain
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.
