Abstract: A processor (213) carries out, after a device is activated and before a blasting medium projected to a projection target object (500), a first inspection process (T1) for determining, in a state in which no blasting medium (400) is supplied to an impeller (110) while each motor of the impeller is rotating, whether a current value supplied to the each motor of the impeller is not more than a first threshold (θ1), and a second inspection process (T′1) for determining, in a state in which the impeller is projecting the blasting medium, whether the current value supplied to the each motor of the impeller is not less than a second threshold (θ2), and displays, on a display (300), at least one of (1) respective determination results of the first inspection process and the second inspection process and (2) a determination result obtained by generalizing the determination results (1).
