Abstract: A hand-operated cutting machine comprising a rotatable saw blade (3), a machine body with drive machinery for rotation of the saw blade, a rear manoeuvring handle (20) with control (17, 18) for a drive motor (2) included in said drive machinery and a front handle bow (25) which has the form of a crow which stretches from one side of the machine body over the machine body or over the saw blade to the other side of the machine body. The handle bow is rotatably attached to the machine body in a hinge (26) with an axis of rotation (24) which is located behind the saw blade and is perpendicular to the plane of the saw blade, that both ends of the handle bow are connected to each other through said hinge, and that the handle bow is fixingly adjustable in different rotational positions.

Abstract: An apparatus forming a portable, hand-operated machine (1, 1', 1"), having a circular cutting wheel (4) or saw blade (4") which is rotatable about a center of rotation (5, 5"), comprises a double-armed holder (9) with a rear arm (20) which, at its rear, free end (27), is connected to the machine at a first hinge, rotatable about a first axis of rotation (18, 18a, 18b, 18") parallel to the center of rotation of the cutting wheel or the saw blade, and, at the other end, is connected rotatably, by means of a toggle joint (22), to a front arm (21) which in turn is connected rotatably, at its front, free end, to a securing device about a second axis of rotation at a second hinge, for rotatable anchoring of the holder and, thus, of the machine on the object which is to be cut or sawn.
