ABSTRACT:
Embodiments of a power miter saw comprises a saw base having a fence for positioning a work piece, a table rotatably connected to the saw base, a miter arm assembly for angularly positioning the table, a saw blade and motor assembly pivotally connected to the table having a normally elevated rest position and being configured to lower a saw blade toward the table, a handle connected to the saw blade and motor assembly for lowering the saw blade into cutting position, an activation switch adjacent the handle and positioned to be engaged by an operator, a proximity sensor disposed on the saw blade and motor assembly for detecting the presence of objects within a zone of detection associated with the table, and electrical circuitry connected to the proximity sensor configured to generate an electrical detection signal in response to the proximity sensor detecting the presence of an object.
