Abstract: Power tools described herein include a tool output, a motor driving the tool output, a battery pack interface, a power switching network coupled between the battery pack interface and the motor, and a controller coupled to the power switching network to control operation of the motor. The controller is configured to operate the motor at a no-load speed at startup and detect a load state of the power tool. The load state indicates whether the power tool is in a loaded state or an unloaded state. The controller is also configured to incrementally ramp up a speed of the motor from the no-load speed to a selected speed when the power tool is in the loaded state and incrementally ramp down the speed of the motor from the selected speed to the no-load speed when the power tool is in the unloaded state.

Abstract: An oscillating power tool has a housing including a handle portion defining a handle axis and a head portion defining an output axis that is perpendicular to the handle axis. The head portion includes a front face intersected by the handle axis. A drive mechanism includes an output shaft configured to oscillate about the output axis in a rotational manner in response receiving torque from a motor. A lighting assembly is configured to illuminate a workpiece in front of the head portion of the housing. The lighting assembly includes a lens arranged on the front face of the housing, a holder coupled to the lens, a plurality of printed circuit boards supported by the holder, and an LED arranged on each of the printed circuit boards. In response to being activated, the LEDs are configured to project a wide-angle beam of light through the lens.
