Maintaining and Sharpening
the Saw Chain
1
Cutting effortlessly with a correctly
sharpened chain
2
3
A properly sharpened chain slices
through wood effortlessly and requires
4
very little feed pressure.
3
Working with a dull or damaged chain
requires more physical effort, exposes
the user to higher vibration levels,
produces unsatisfactory cutting results
and increases wear.
Clean the chain.
N
Check the chain for cracks in the
N
links and damaged rivets.
Replace any damaged or worn
N
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.
WARNING
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.
Chain pitch
The chain pitch (a) is marked on the
depth gauge end of each cutter.
