Abstract:
An electric saw (2) includes a stroke arrangement (4) driven in a reciprocating manner and having a tool receptacle (8) for a saw blade (10), a housing (14) which extends along a stroke axis (A) of the stroke arrangement (4) and which forms at a working tool-side end (12) a housing opening (16) from which the stroke arrangement (4) projects, and which forms a receiving space (26) in which is arranged a motion transforming device (24), the stroke arrangement (4) being supported at the housing (14) by a bearing element (30) which forms a sliding bearing (28) and is arranged between the motion transforming device (24) and the housing opening (16), with an air flow (L) being directed toward the housing opening (16) so that particles (P) can be prevented from entering the sliding bearing (28), with the bearing element (30) limiting the receiving space (26) toward the housing opening (16), and with a flow path (46) by which the air flow (L) is guided being provided at an outer side (40) of the bearing element (30) facing the housing opening (16).
