Replace the chain sprocket
–
replace after using two saw chains
or sooner
–
if the wear marks (a) on the sprocket
are deeper than approx. 0.5 mm
(0.02 in) since this would reduce the
service life of the saw chain. You
can 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.
