My Sears table saw was used when I inherited it 10 years ago, so I don't know how old it is. Today I was using it and once when I turned it on, instead of spinning up as usual, it hummed and turned very slowly for a few seconds then spun on up and worked fine. The next time I turned it on, though, it hummed and spun very slowly for about 15 seconds, then I heard a click (circuit breaker?) and it died.
The reset button doesn't seem to be popped out, and pushing it doesn't do any good. I can spin the blade manually, and it certainly doesn't drag, but it doesn't seem to turn as freely as it used to.
When I got the saw, there was no manual, and Sears doesn't have one available for viewing on their web site.
So I have 2 questions:
1) Does anyone have a guess as to the problem?
2) Does anyone have a manual for a 10" model 113.298050 Sears table saw?

Thanks a lot.
