6.2 Shaving
The ENCHEN Blackstone shaver supports both wet and dry shaving.
- Dry Shaving: For a quick and convenient shave, ensure your face is clean and dry. Move the shaver in small, circular motions against the direction of hair growth.
- Wet Shaving: For a more comfortable shave, especially for sensitive skin, apply shaving foam or gel to your face. Move the shaver gently in circular motions. Rinse the shaver head under running water during and after shaving to prevent clogging.
The ESM Smart Shaving System ensures consistent power and prevents hair pinching, even when the battery is low.

8. Troubleshooting
If you encounter any issues with your shaver, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Shaver does not turn on. | Battery is depleted; Safety lock engaged. | Charge the shaver fully. Ensure the safety lock is disengaged before sliding the power switch. |
| Poor shaving performance. | Cutter heads are dirty or worn; Battery is low. | Clean the shaver heads thoroughly. Charge the shaver. If performance doesn't improve, consider replacing the shaver head assembly. |
| Shaver pulls hair. | Cutter heads are clogged; Battery is low. | Clean the shaver heads. Ensure the shaver is fully charged. The Intelligent Anti-pinch feature should prevent this, but a very low battery can still affect performance. |

10. User Tips
- For best results, shave before washing your face in the morning, as skin tends to be less swollen.
- If you have longer stubble, use the pop-up trimmer first to shorten the hairs before using the main shaver heads. This helps prevent pulling and ensures a smoother shave.
- Apply light pressure and move the shaver in small, circular motions. Avoid pressing too hard, as this can irritate the skin and reduce shaving efficiency.
- Regularly clean the shaver head after each use to maintain hygiene and optimal cutting performance.
