A power tool (10) includes a table (14). A shaft (40) is fixedly secured to the table (14). The power tool (10) also has a support housing (32) supporting a motor (22) and a working tool (18) driven by the motor (22). The support housing (32) is disposed on the shaft (40) adjacent to the table (14) and is axially movable along the shaft (40) and laterally pivotable about an axis of rotation. In addition, the power tool (10) has a locking mechanism (30) for locking the support housing (32) at a predetermined lateral position, wherein the locking mechanism (30) includes a handle (54) disposed on the shaft (40). The handle (54) is rotatable in two directions with respect to the shaft (40), such that rotation of the handle (54) on the shaft (40) urges the support housing (32) into locking contact with the table (14). A method for operating the power tool (10) is also disclosed herein.
