Motorisch angetriebene Feinsäge

摘要

A motorized miter saw includes a base having a turntable mounted thereon for rotation about a vertical axis, a cutting unit having a mounting apparatus for securing the cutting unit on the turntable for movement to non-cutting and cutting positions relative to the turntable, and an indexing apparatus for releasably securing the turntable in predetermined positions of angular adjustment. The saw also includes a detent receiving recess at each predetermined position, a detent alignable by rotation of the turntable with any one of the recesses and a detent biasing member constantly biasing the detent into the specific recess which it is aligned. The indexing apparatus also includes a detent override apparatus selectively positionable to withdraw the detent form the recess and free the turntable for micro angular adjustment relative to any predetermined position, a latch for releasably securing the detent override apparatus in the detent withdrawal position, and a lock for releasably securing the turntable in any selected position of micro angular adjustment.
