ATTENTION:
DEALERS, CHAINSAW USERS, AND ANYOME WHO
SERVICES DRIVE SPROCKETS-IMPORTANT SAFETY INFORMATION.
Always turn your saw's engine before handling the drive sprocket.
Failure to do so can result in sever injury.
Your drive sprocket, the third member of the cutting team, deserves
regular attention and maintenance just like your bar and chain. A
misused sprocket will cause patterns of chain wear which can damage
the guide bar and reduce the life of all three components. A damaged
sprocket cannot be repaired, it can only be inspected and replaced.
Here are the things to look for, and the steps to take.
