7.2 Deep Cleaning
For a more thorough cleaning, use the provided cleaning brush to remove any stubborn hair clippings from the blades and shaving chamber.
7.3 Blade Replacement
The razor blades are consumables and will dull over time. For best shaving results, it is recommended to replace the blades periodically. Replacement blades can be purchased separately from authorized retailers.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Shaver does not turn on. | Low battery or travel lock activated. | Charge the shaver fully. Deactivate the travel lock by pressing and holding the power button for 3 seconds. |
| Poor shaving performance / pulling hair. | Blades are dull, shaver head is clogged, or beard is too long. | Clean the shaver head thoroughly. If beard is long, use the pop-up trimmer first. Consider replacing the blades if they are old. |
| Shaver stops unexpectedly. | Motor overload (e.g., too much pressure, clogged blades). | Clean the shaver head. Reduce pressure during shaving. The smart anti-pinch beard feature should prevent this in most cases. |
| Digital display not working. | Shaver is off or battery is completely drained. | Turn on the shaver. Charge the shaver for at least 10-15 minutes to see if the display reactivates. |
