ABSTRACT:
A power cutter is disclosed which is capable of selectively changing the discharge direction of dust discharged from a dust discharge port of a dust suction-discharge fan and, hence, which is capable of optimally adjusting the dust discharge direction according to the operational condition or operational position of the power cutter. An elbow-shaped auxiliary discharge pipe is coupled to the dust discharge port of the dust suction-discharge fan in such a manner that it can be turned and kept at any turned position. In addition, a belt tensioning clutch is provided to permit selective connection and disconnection of the belt drive transmission between the power source and the dust section-discharge fan. This permits fan operation to be interrupted when not needed.
