The Super Saw is a hybrid if I recall correctly. This means no motor hanging out the back so disconnecting the motor from the arbor will involve a little digging. Once the belt is off fire up the motor and see if your noise is gone. With the saw unplugged and the blade off, grip the arbor and see if there is any play side to side or in and out. You can also spin the arbor slowly and see if you see, hear or feel any irregularities; it should be smooth as silk. Let's start there. Please let us know what you find.

Missing a tooth? First thing I would check.

I had a pulley work loose once on the contractor saw.
Belt felt smooth and tight but made a racket.
Have you figured it out yet?

Thank you for the replies. No time today for the shop. During the initial exam, I used the blade for a couple of turns...so I think the blade is tight. I will check your suggestions one by one Monday morning and report back.

Check for build up on the blade sides or in the gullet areas. Foam/plastic plus friction often leads to melted substance.

Life happened over the past eight days. Constant rain made shop time possible.
GeeDub: yes it is a hybrid; with blade and belt off, arbor has no play side to side but in & out there is the tiniest movement, arbor spins smoothly.
EightFingers: the blade was tight
Pirate: all teeth present and accounted for
Gary G: pulleys are tight
Buckhorn: blade is not spotless but no signs of build up
Other results: there was some junk (very small) in the groves of the motor pulley, motor spins smoothly, but......the vibration is there when I run it without the blade. I cannot feel any play in the shaft.
Questions: Do I have to stop using the saw? My first thought is to use the saw until it stops or gets bad enough I'm no longer comfortable using it. I would love to have a 2hp or 3hp motor, is that a reasonable switch out for a dumb old guy? I do have 220 near by.

Without the belt on the pulley, is there vibration with the saw on?
