FAQ

What is the drive sprocket?

The drive sprocket and the clutch drum are connected to the saw motor. The sprocket is designed to drive the proper-pitched chain around the guide bar.


How long should the drive sprocket on my saw last?

You should replace drive sprocket systems after every two chains, or sooner. It's important not to run a new chain on a badly worn drive sprocket.
