^^^^^^^^^^^^^
So we know the start button and the relay coil work. There should be a pair
of contacts on the relay, in parallel with the start switch, which start to
supply holding current to the relay, so when you let go the button, the
relay doesn't open. Find this part of the circuit, and look for burned
contacts or a broken wire. That HAS to be it.
Trace that circuit. It may also go through some thermally
tripped switches on the contactor, to drop power when it draws too much
current -- such as when the saw stalls, or when one of a three-phase
feed is open. (Is this powered from three phase?)
Good Luck,
DoN.
