Why does the vibration of the Mijia Rotary Tool Kit cause numbness in the hand during use?

Question

Accepted Answer

If the vibration of the Mijia Rotary Tool Kit causes numbness in the hand during use, please refer to the following troubleshooting steps:
1. The grinding head could be loose. Make sure all accessories are properly installed and tightened.
2. The selected speed level could be too high. Reduce the speed to a comfortable level.
3. Uneven force application could increase vibration. Apply consistent and moderate pressure during use.
4. The motor inherently produces vibration during operation. This is normal, but taking breaks can reduce discomfort.
5. If the problem persists, the tool could require professional inspection. Contact the after-sales service center for assistance.
