Abstract: A chain saw having reduced transmission of vibration includes an internal combustion engine, a crankcase, and a crankshaft; a support assembly, the support assembly including a frame and at least one manual gripping handle; and a vibration isolation system for connecting the engine and the support assembly and inhibiting the transmission of vibration. The vibration isolation system comprises: a front vibration mount having an axis parallel to the crankshaft for connecting the crankcase to the front of the frame and a rear vibration mount having an axis parallel to the crankshaft for connecting the cylinder of the engine to the rear of the frame. The front vibration mount and the rear vibration mount are disposed so that a first imaginary line connecting their axes intersects an imaginary vertical plane containing the crankshaft at a point above the crankshaft.
