N If you use a biological chain and bar

chain and guide bar.
Replace the chain sprocket:
– 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
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.
STIHL recommends the use of original
STIHL chain sprockets.
The chain sprocket is driven via a friction
clutch. Have the chain sprocket replaced
by a servicing dealer.
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.
