Before use: Read manufacturer's instructions. Ensure drill, cable, and bit are compatible and in good condition. Insert bit securely—never change while powered on.

During use: Start at lowest speed. Hold bit lightly and keep moving. Avoid pressing hard, staying in one spot, or thinning nails. Keep away from skin and cuticles. Never use on injured or irritated nails.

Safety: Wear eye protection if recommended. Avoid inhaling nail dust. Stop immediately if you feel heat, pain, or discomfort. Learn proper technique before use—incorrect handling can damage nails or skin. Do not use on others unless trained in hygiene and disinfection.

After use: Switch off and disconnect before cleaning or changing bits. Store according to supplied instructions.
