Unisaw chirp

I can’t say that I’ve ever heard that from my Unisaw.

Sounds like something needs some lube though. Check your manual to see what gets grease and when gets oil.

Some electric motors have a centrifugal switch to switch from start to run. If yours does it may be the switch clicking as the motor winds down. Maybe you cold take the belts off and isolate the problem that way.

I had this same problem with my Delta contrator’s saw. The culprit was the belt, it rubbed against the top but only when it powered down when the blade was set at full height.
Like Joe said, try running just the motor itself.
Add the belts, no blade.
Try putting the saw in different positions, etc.
And narrow down the culprits.

Folks
I went to the shop tonite armed with the above suggestions, which, BTW, I thank you for your help. So I get started…..belts off. Right away I notice one of the belts is fraying….still looking though I find the arbor is OK (whew)....flip the motor on and detect a little squeel….turn it off and the chirp returns….I turned the motor shaft and bearings feel ok & no squeek…..powered the motor back on & started to tilt…squeeeeel. And the noise is coming from the end of the motor….I take the cover off & find the impeller loose…Cleaned everything up, tightened the impeller down & saw is back to normal….almost anyway. I’ve got the belts ordered. Thanks again for your suggestions!

So happy for you. Fortunate that you were prompt in making the repair quickly. If you had waited longer it is possible that the motor could have incurred expensive damage.
