I have a relatively new Sawstop CNS and when it is shut off it vibrates and makes a loud noise. I have tried to capture it in this video i took. Does anyone know if it is normal?

    I'm sure the best advice here would be to contact Sawstop directly.

From what I have read, this is not all that unusual on contractor saws. What is happening is that as the motor slows down, it slows at a different rate than the belt, so there is some slippage as the speeds equalize.

Here is a link to a post on Woodnet that describes it in more detail. As long as it is running fine when under power, there really isn't anything to worry about.
