Checking the Chain Sprocket

Disengage the chain brake: Pull the
N
hand guard toward the front handle.
Remove the chain sprocket cover,
N
chain and guide bar.
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.
STIHL recommends the use of original
STIHL sprockets to ensure correct
operation of the chain brake.
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.
