How to Use

Preparation

1. Charge the device fully with a USB‑C cable before first use.

2. Select and insert the desired grinding head; ensure it’s secured and the protective cover is in place.

3. Clean nails — remove polish or debris, and optionally soak/soften nails if needed.

Operation

1. Power on: Press the main power/speed button to turn on. The LED display will show the current speed level.

2. Set speed: Use the speed/gear button to increase or decrease RPMs according to the task and bit type. Start low and increase as needed.

3. Set rotation direction: Press the direction switch to choose clockwise or counterclockwise rotation depending on your dominant hand and technique.

4. Use LED lamp: Press the nail lamp switch to turn on the built‑in LED light for improved visibility.

5. Work gently: Place the rotating bit lightly on the nail and move slowly. Avoid applying excessive pressure or staying in one spot to prevent heat and over‑filing.

6. Finish & clean: After use, turn the device off, remove the bit, and clean both the bit and protective cover. Wipe the body with a dry cloth.

Safety Tips

• Start at low speed and increase gradually.

• Do not force coarse bits on natural nails; use appropriate bits for natural vs. artificial nails.

• Avoid skin contact with rotating bits — use gentle motions around the cuticle.

• Clean bits regularly and disinfect if used on multiple clients.

• Allow breaks to prevent heat buildup in nails during extended sessions.
