Abstract

An engine-operated machine such as an electric generator includes a box-shaped casing, an engine disposed in an upper portion of the casing, a machine unit disposed in a lower portion of the casing, and a power transmission assembly by which the engine is operatively connected to the machine unit. The box-shaped casing includes a casing body having front and rear openings, a pair of upper doors mounted on the casing body for opening and closing upper portions of the front and rear openings, respectively, a pair of lower doors mounted on the casing body below the upper doors for opening and closing lower portions of the front and rear openings, respectively, independently of the upper doors, and a pair of screen doors mounted on the casing body inwardly of the lower doors, respectively, for opening and closing the lower portions of the front and rear openings, respectively. A fuel tank is slidably removably disposed in the casing adjacent to the machine unit. When in operation, the upper and screen doors are closed and the lower doors are open. The closed screen doors protect the internal mechanism from being tampered with or other forms of attack. The engine-operated machine is of a small height, highly compact, and small in size.
