I regularly use a friends K700. It is approximately 15-20 years old.

(kelly green panels, all manual tilt and lift mechanisms)

The motor on the main blade is an ATB IMB14.

Not sure what is on the Scoring blade. I've never used the scoring blade.

The saw has always been 100% reliable, powerful and smooth.

Yesterday, after maybe 2 hours of on and off light cutting, I turned it on and it turned very slowly for a few moments, then shut off. I cycled the on/off switches - nothing happened. I turned off the power at the breaker, checked around the motor and saw assembly for and blockages - it was very clean. Turned everything by hand and it was very smooth. Turned the power back on, hit the on button, and it did the slow turning again and turned off.?I believe that there was a slight whiff of "hot electronics" smell.

Does this ring a bell for anyone? Any thoughts on what this might be?
