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 about
0.02 in (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.
