One of the switches in the ¡°stop¡± circuit is open. Could be due to debris or a faulty/failed switch. There are probably four switches, all connected in series such that if any are open, the machine will refuse to start. There are two button switches (Stop and E-Stop) and two microswitches (blade cover and hinged chassis access door). They are powered by 24VAC. Check continuity.

Hi all. Probably simple fo someone who knows more than I do:
Over the years, occasionally I¡¯d turn off the saw with the small red button (not the emergency twist knob ) and then the saw wouldn¡¯t start up again for several tries. I¡¯d blow out or suction out the dust and it¡¯d then start up. Inconclusive whether dust was the cause.
Well this time, that protocol didn¡¯t work. I opened up both switches, checked connections, blew out dust, untwisted the wire (shown in photo). No luck.
The power from the main cutoff is there - hums until warmed up, indicating ready to go.
I opened up the main panel, blew out the minor dust, traced the power and switch wires to various terminals, and made sure those wires were tight.
I pressed all the fuse buttons (I assume they¡¯re fuse buttons) to ¡°reset¡± them. The black ones depress, the red ones do not.
Still no power to the saw.
Anyone know what¡¯s going on here, or what I can do myself?
Alternatively, anyone know a tech in central jersey that could come fix it? I have the wiring diagrams although they¡¯re confusing to me.
Thanks
Mike
