Variable Speed Trigger Switch Assembly
The variable speed trigger utilizes a sliding potentiometer that transmits a low-voltage signal to the motor controller. Mechanical wear on the resistive track or the accumulation of fine particulates inside the switch housing causes intermittent signal drops, leading the controller to immediately cease current flow to the brushless motor to prevent uncontrolled operation.

Main Control PCB Assembly
This board contains the Electronic Speed Controller (ESC) and thermal sensors; 'random' shutdowns can occur if a cold solder joint on a MOSFET lead expands and contracts during operation, breaking the circuit. The board's firmware also initiates a safety shutdown if it detects voltage fluctuations that exceed the programmed safety threshold for the 56V lithium-ion system.
