Use the smoothing disc to smooth out the nail edges or to smooth callused skin that forms around the fingernails and toenails. Use the buffing disc to buff away ridges off the surface of the nail or to gently push back and buff away excess cuticles. Use the shining disc to buff nails to a high gloss finish. Securely place magnetized disc onto device. Push power button once for low speed, twice for high speed; a third push of the button will turn the device off. Use low speed for gentle grooming of cuticles and nail surface. Use high speed for quicker shaping and buffing. Gently place the cushioned disc to the tip of the nail or on the nail surface.
