Claim 0:
1. A portable machine tool having a pad tool and a drive motor, which is arranged in a machine housing for driving the pad tool to produce an oscillating or rotating or eccentric movement of a processing face of the pad tool, wherein the portable machine tool can be guided with the processing face forwards in a main working direction and laterally transversely relative to the main working direction in at least one transverse working direction for a grinding or polishing operation of a workpiece surface, wherein the machine housing has a front side facing forwards in the main working direction and a rear side opposite the front side, the rear side having at least one of an extraction connection for extracting particles generated by the pad tool or a handle portion to be gripped with a hand, the extraction connection or the handle portion protruding from the rear side of the machine housing in a direction opposite the main working direction, wherein the portable machine tool has, for the pad tool, a covering device, which has at least one protection wall which is arranged upstream of at least one side face of the pad tool which extends beside the processing face with respect to the main working direction or the at least one transverse working direction in order to protect against contact with obstacles, wherein the at least one protection wall of the covering device completely or substantially covers side flanks of the pad tool, and
wherein the covering device is a one-piece clamp, the clamp comprising a base member and two lateral members extending rearwardly from the base member, the two lateral members clamping the machine housing at mutually opposing sides, and
wherein the base member comprises a positive locking contour, and
wherein the front side of the machine housing comprises a plug-type receiving member for receiving the positive locking contour of the covering device base member for releasably securing the covering device to the center of the machine housing without application of a tool to the covering device, and
wherein the covering device is attachable to and removable from the machine housing without removing the pad tool, and
wherein the processing face of the pad tool is substantially rectangular and has a front portion extending from the front side of the housing, the front portion having a front end with two corners, and
wherein the at least one protection wall of the covering device comprises a base member portion extending from the base member of the covering device and two lateral member portions extending respectively from the two lateral members of the covering device, the base member portion covering a portion of the front portion of the rectangular processing face and each of the two lateral member portions covering a portion of a respective one of the side flanks of the pad tool, and
wherein at least one recess is formed between the base member portion of the protection wall and one of the two lateral member portions of the protection wall, at least one of the two corners of the front end of the processing face protruding through the at least one recess for an edge-side processing operation of the workpiece surface.
