But if you do, here's one way to make it work. Otherwise, the saw won't even power on. Be sure to turn off the sensor with the key to prevent any accidental firing. Basically, you can fool the sensor into thinking that the brake is next to a blade by screwing a piece of heavy gauge wire (heavy so that it doesn't flop into the cutter) to the aluminum brake. Then loop the wire up next to the arbor nut, making sure to keep it away from the cutterhead.
Mission accomplished.
