Replace the chain sprocket
– replace after using two saw chains
or sooner
– if the wear marks (a) are deeper
than 0.02 in (0.5 mm) since this
would reduce the service life of the
saw chain. Use a gauge (special
accessory) to check the depth of the
wear marks
Using two saw chains in alternation
helps preserve the chain sprocket.
STIHL recommends the use of original
STIHL chain sprockets.
