Fitting a new chain sprocket
– after use of two saw chains or
earlier
– if the wear marks (arrows) are
deeper than 0.02 in (0.5 mm) –
otherwise the service life of the saw
chain is reduced – use check gauge
(special accessory) to test
Using two saw chains in alternation
helps preserve the chain sprocket.
For the removal and installation of chain
sprocket and clutch described in the
following, a locking strip is required to
immobilize the piston in the cylinder. The
locking strip is included with the
replacement chain sprocket.
STIHL recommends use of original
STIHL chain sprockets in order to
ensure optimal functioning of the chain
brake.
