Abstract
A power working machine has a noise level display device which enables the noise level of the machine to be easily recognized with the naked eyes. When compressed air that is pressurized and delivered by a blower fan is delivered to an air-ejecting pipe, a noise level proportional to the magnitude of the force of the ejected air flow is indicated by the noise level display device, which is mounted on the air-ejecting pipe.
