Saw was running fine. On same circuit had a compressor and something else running when the saw bogged w.out the blade touching anything, and 3 seconds of bogging smoke shot out of the motor vents and she packed up. Checked one of the brushes and it didn't look fried, just a little carbon maybe on the magnet, but maybe it is. The bogging was almost like the power was insufficient, which is what I thought at first when it bogged since a couple other high draw appliances were drawing same time.
Appreciate your thoughts on what the problem is - whether I need to replace the motor or just the brushes.
Thanks!
