ABSTRACT:
A motor-driven saw has a gearing housing (4), which has at least two housing parts (6, 8), a stroke bar (10), which in operation executes a stroke movement in the direction of a stroke axis (26), and a reciprocating movement generator (36) that can be turned on or off, by virtue of which the stroke movement is superimposed with a reciprocating movement executed transverse to the stroke axis (26). All bearing zones (30, 44, 62) over which the reciprocating movement generator (36) is supported on the gearing housing (4) in a preferred direction of advance (16) of the saw, are arranged in the same carrying housing part (6).
