How to connect the "START-STOP" button to a miter saw Makita LH1040?

Hello! I could not find the schemes for this miter saw, but according to the detailing there I could determine what was installed there: a collector motor, a soft starter, a block of switches, a relay. Most likely the “stop” and “start” buttons are fixed buttons, such as PNVS. They include a relay coil, which supplies voltage to the soft starter, which in turn is connected in series with the motor. If the button is similar to a PNVS, then a phase is simply applied to it (possibly zero), and one button closes and the second opens, then 2 wires should come to the button block (phase to it and phase from it to the relay).
