Replace the chain sprocket
–
after using two saw chains or
sooner
–
if the wear marks (arrows) on the
sprocket are deeper than approx.
0.5 mm since this would reduce the
life of the chain. You can use a
gauge (special accessory) to check
the depth of the wear marks.
It is best to use two saw chains in
rotation with one sprocket.
A locking strip is required to block the
piston in the cylinder when the chain
sprocket and clutch are removed and
installed as described below. The
locking strip is supplied as standard with
the replacement sprocket.
STIHL recommends the use of original
STIHL sprockets to ensure correct
operation of the chain brake.
