ABSTRACT:
A portable machine tool, comprising a base structure, a work surface supported by the base structure for supporting, in use, a workpiece, and a column pivotally connected to the base structure and being pivotal between an upstanding operative position in which the column extends upwardly above the work surface and a lateral inoperative position. An operating unit is attached to the column and is supported thereby above the work surface in the operative upstanding position for operating, in use, on the workpiece. A locking arrangement releasably secures the column in the operative upstanding position. Preferably the column is pivoted behind and to the rear of the base structure, and a part of the work surface is removable to expose a space inside the base structure in which the operating unit is at least partially housed when the column is pivoted to the inoperative lateral position. In this way the machine tool, which is preferably a radial arm saw, is made more compact for transporting and/or storage.
