When working with an electric file, a practitioner should?

Keeping the file moving while working with an electric file is essential for maintaining a smooth application and preventing damage to the nails. Continuous movement helps to avoid overheating, which can occur if the file is held in one position for too long. Overheating can lead to discomfort for the client and potential injury to the natural nail or skin. Additionally, constant movement allows for a more even filing action, ensuring that the nails are shaped correctly and reducing the risk of creating grooves or uneven surfaces.

Using an electric file effectively requires an understanding of the tool's mechanics, which includes knowing how to manipulate it safely and effectively. By ensuring that the file is constantly in motion, a practitioner can achieve the desired results while minimizing risks associated with static pressure and intense friction on the nail or surrounding tissue.
