What saw do you have? If it’s the one I’m thinking it is, check the capacitor under the switch cover.

Cheers,

Thanks for responding Brad. It is the 40-560 2 speed. The switch seems to work. What happens is I turn it on and the arm moves just a tiny bit, really like a little jerk.

As long as the arms move freely and are not binding, it could be a couple of things, but the easy free stuff should be checked first. Could be just some sawdust in the switch, preventing a complete connection, so try blowing it out with some compressed air. Make sure all the wiring is secure as well. If that doesn’t do it, I’d check the capacitor next. Flipping the switch and it just humming usually points to the start circuitry, and the start cap is easy to test with a cheep multimeter. The capacitor is behind the switch (#86 in the diagram below):

If that proves ok, then I’d look at the centrifugal switch or whatever that motor has in place to drop the start circuitry in and out.
