Abstract
A powered hand tool includes a motor, a cutting member drivable to cut a workpiece, and a drive system interconnecting the motor and the cutting member and operable to drive the cutting member in response to operation of the motor. A housing at least partially encloses the cutting member and the motor and a debris removal system is movable between a first position and a second position. The debris removal system is operable to clean a portion of the drive system when in the second position. The debris removal system includes an abrasive member, an automatic actuator, and a sensor operable to selectively generate a signal. The automatic actuator is movable between an actuated position in which the abrasive member moves to the second position and a non-actuated position in which the abrasive member moves to the first position in response to the sensor.
