Maintaining and Sharpening
the Saw Chain
Sawing effortlessly with a properly
sharpened saw chain
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!
