1. A power tool comprising:

  • a work-piece support surface;

    a swing arm assembly movable along a swing path between a first swing arm position whereat a portion of a shaping device supported by the swing arm assembly extends above the work-piece support surface and a second swing arm position whereat the portion of the shaping device does not extend above the work-piece support surface;

    a latch pin movable between a first latch pin position whereat the latch pin supports the swing arm assembly in the first swing arm position and a second latch pin position whereat the latch pin does not support the swing arm assembly in the first swing arm position wherein the latch pin includes an actuation ramp;

    an actuator module configured to receive a plurality of actuators, and a first actuator received in the actuator module, the actuator module including a first actuating module position whereat the first actuator is aligned with a portion of the swing arm assembly, and whereat in the first actuating module position within the actuator module the first actuator is further aligned with the actuation ramp; and

    a control system configured to actuate each of the plurality of actuators when positioned in the first actuating module position, the power tool configured such that actuation of each of the plurality of actuators when the latch pin is in the first latch pin position and supporting the swing arm assembly in the first swing arm position results in(i) movement of the latch pin from the first latch pin position to the second latch pin position, and(ii) forcing of the swing arm assembly away from the first swing arm position and toward the second swing arm position.
