If you're not pressing the saw "ON" button, you're not sending power to the motor.? ?Note that
running?a 3 phase motor on 2 legs won't hurt it, but trying to
start?a 3P motor on two legs isn't a great idea and usually won't work.? Two phases usually lack the torque to overcome starting inertia, but once spinning, two phases just provide 2/3 power.? This is how the <$100 "phase converters" work.? They have a capacitor to give a short starting burst to the 3rd leg and then once spinning the they just pass the two legs thru ( a free?"phase converter" is tie a rope around the motor and manually start it, like a lawn mower)
