Abstract

An electric power saw/cutter includes a rotatable saw structure, a rear handle with a switch/speed control, a front handle, and a drive unit for rotating the saw structure. The drive unit includes a saw structure drive arrangement to which the saw structure is attachable, a transmission for driving the saw drive arrangement, an electric motor for driving an input shaft of the transmission, and a support structure for holding/carrying the saw structure drive arrangement. The transmission and the electric motor may be characterized in that the front handle and the rear handle are directly connected to each other to form a handle unit, which unit is resiliently connected to the drive unit, so that vibrations from the saw blade and drive unit will be reduced in the handle unit.
