Maintaining and Sharpening
the Saw Chain
Sawing effortlessly with a properly
sharpened saw chain
2
1
A properly sharpened saw chain cuts
through wood effortlessly even with very
little pushing.
Never use a dull or damaged saw chain
– this leads to increased physical strain,
increased vibration load, unsatisfactory
cutting results and increased wear.
Clean the saw chain
N
Check the saw chain for cracks and
N
damaged rivets
Replace damaged or worn chain
N
components and adapt these parts
to the remaining parts in terms of
shape and level of wear – rework
accordingly
Carbide-tipped (Duro) saw chains are
especially wear-resistant. For an optimal
sharpening result, STIHL recommends
STIHL servicing dealers.
WARNING
Compliance with the angles and
dimensions listed below is absolutely
necessary. An improperly sharpened
saw chain – especially depth gauges
that are too low – can lead to increased
kickback tendency of the chain saw –
risk of injury!
Chain pitch
The chain pitch marking (a) is embossed
in the area of the depth gauge of each
cutter.
Marking (a) Chain pitch

The diameter of file to be used depends
on the chain pitch – see table
"Sharpening tools".
The angles of the cutter must be
maintained during resharpening.
