Do not polish nails mid-air to avoid skin injury. Low-Speed Start: Begin at the lowest speed to get used to vibration. Gradually increase speed after 10 seconds. Short Polishing Sessions: Follow the 3-second rule. Do not polish one single spot for more than 3 seconds. Stop immediately if you feel heat on nails to release heat. Correct Polishing Area: Only use drill bits on nail surface. Avoid touching nail side walls and cuticles to prevent tearing and bleeding.
