5. Operating Instructions
The CkeyiN Electric Razor supports both dry and wet shaving for your convenience.
General Shaving Tips:
- For best results, ensure your beard length is below 2mm. If you have a longer beard, it is recommended to trim it down to 1-2mm using a professional electric shaver or trimmer before using this foil shaver for a precise finish.
- Hold the shaver at a right angle (90 degrees) to your skin.
- Move the shaver against the direction of hair growth using gentle, straight strokes. Avoid circular motions.
- Stretch your skin with your free hand to make the hairs stand upright and ensure a closer shave.

Dry Shaving:
For a quick and convenient shave, use the shaver on dry skin. Ensure your face is clean and dry before starting.
Wet Shaving:
For a more comfortable and smoother shave, apply shaving foam or gel to your face before using the shaver. The shaver is designed to be waterproof for wet use.

7. Troubleshooting
If you encounter any issues with your CkeyiN Electric Razor, refer to the following common problems and solutions:
- Shaver not turning on: Ensure the shaver is fully charged. If the battery is depleted, connect it to a power source and allow it to charge for at least 30 minutes before attempting to turn it on again.
- Poor shaving performance / pulling hair:
- Check if the foil head is clean and free of hair buildup. Clean it as described in the Maintenance section.
- Ensure the foil head is not damaged or worn out. Replace it if necessary.
- Make sure your beard length is appropriate (below 2mm) for the foil shaver. Trim longer hair first.
- Apply gentle pressure and shave against the direction of hair growth.
- Battery not holding charge: Ensure the charging cable and adapter are working correctly. If the issue persists after trying a different cable/adapter, the battery may need servicing.
