The electric haircutting machine includes an electrical drive motor, cutting blades driven by the drive motor, a device (22) for oiling the cutting blades and a device (20) for detecting an oil deficiency of the oil lubricating the cutting blades. The device (22) for oiling the cutting blades is connected with and responsive to the device (20) for detecting the oil deficiency, whereby the device for oiling the cutting blades is automatically activated to oil the cutting blades when the oil deficiency is detected. The device for detecting the oil deficiency detects whether or not motor current consumption, cutting blade vibration noise, haircutting machine sound level, cutting blade temperature, force acting on one of the cutting blades or drive motor rotation speed exceeds a corresponding predetermined threshold or not in order to establish the presence or absence of the oil deficiency.
