摘要：An apparatus including a grip sensor for controlling the number of revolutionsof an engine. The grip sensor detects whether or not fingers of an operator approachtoward the grip sensor or the former come in contact with the latter. Usually, the gripsensor is incorporated in the gripping portion of a control lever which controls actuationof working tools. The apparatus includes a controller for outputting a deceleration signalin response to an output signal from the grip sensor in order to reduce the currentnumber of revolutions of the engine to a level lower than the number of revolutions ofthe engine in the high operative state when no detection is achieved by means of the gripsensor. Alternatively, the controller may output an acceleration signal in response to anoutput signal from the grip sensor in order to raise the current number of revolutions ofthe engine to a level higher than that the engine in the idle rotational state whendetection is achieved by means of the grip sensor.
