Checking and Replacing the
Chain Sprocket
Disconnect the plug from the wall
N
outlet.
Remove the chain sprocket cover,
N
chain and guide bar.
Engage the chain brake to lock the
N
chain sprocket – see "Chain Brake".
Replace the chain sprocket
a
after using two saw chains or
–
sooner
if the wear marks (a) 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.
STIHL recommends the use of original
STIHL sprockets to ensure correct
operation of the chain brake.
