Title: Gas engine operated machine

Abstract: A gas engine operated machine includes a machine unit that includes an engine burning a gas fuel, and a working device driven by the engine, the machine unit being surrounded by and fixed to a rigid frame formed by framing an elongated frame material, and an upper portion of the machine unit being covered with a roof, such that the operated machine is easy to handle and attractive in appearance, and it is possible to effectively avoid another object colliding against piping parts such as a gas fuel pressure regulator and the like, or rain water, dust and the like striking against the piping parts, thereby stabilizing the operation of the piping parts and enhancing the durability of the piping parts. A roof includes an upper cover bulged upwards, and a lower cover mounted to a lower surface of the upper cover, and supported on a rigid frame through vibration-damping members. A gas fuel pressure regulator, a gas shut-off valve and a connecting pipe connecting the regulator and the shut-off valve in series to each other are mounted on an upper surface of the lower cover, so that they are covered with the upper cover.
