Zero-Gapping Caution: Users often try to "zero-gap" the blades (aligning them perfectly flat) for closer shaves. Be careful; if the moving blade overlaps the fixed blade, it will nick or cut the skin. Always test it on your palm before your face.
The Oiling Sensor: The LED display has an oiling indicator. Do not ignore it. Ceramic blades generate less heat, but they still need lubrication to reduce friction on the motor
