Control Assembly
The control assembly contains the Electronic Speed Controller (ESC) which manages the phase-firing of the brushless motor. A failure in the logic gate or a degraded MOSFET will allow the motor to start (on-state) but will trigger an automatic shutdown once the current draw exceeds a threshold or the commutation timing fails. This part replaces the entire logic and power distribution board responsible for the shutdown behavior.

Trigger Switch Assembly
Variable speed triggers use a potentiometer or Hall effect sensor to communicate demand to the controller. If the internal contact points are oxidized or the signal wire has high resistance, the controller may interpret the fluctuating signal as a 'power down' command or a 'stalled' signal, resulting in intermittent operation.

Battery Terminal Block
The 56V system requires a clean data connection through the center pins to monitor battery thermistors and cell balance. If the terminal block pins are slightly recessed or contaminated, the tool may lose communication with the Battery Management System (BMS) during the vibration of startup, causing an immediate safety shutoff to protect the cells.
