5.2 Trimming Techniques
For an even trim, always move the trimmer against the direction of hair growth. Use light pressure and ensure the flat side of the guide comb is fully in contact with your skin.
- Beard Trimming: Start with a longer guide comb and gradually reduce the length until your desired style is achieved.
- Detailing and Edging: Remove the guide comb for precise lines and sharp edges. Hold the trimmer perpendicular to the skin for clean lines.
- Waterproof Use: The trimmer is fully waterproof. It can be used in the shower for convenience or rinsed under the tap for easy cleanup.

- Turn off the trimmer and remove any attached guide comb.
- To remove the blade, gently push the blade assembly forward from the top until it detaches.
- Rinse the blade and the trimmer body under running water to remove hair clippings.
- Use the provided cleaning brush to remove any stubborn hair from the blade and internal components.

- To reattach the blade, align it with the trimmer body and press firmly until it snaps into place.
6.2 Oiling the Blades
For optimal performance and longevity, apply a few drops of the included blade oil to the teeth of the trimmer blade after every few uses or after cleaning. Turn the trimmer on for a few seconds to allow the oil to distribute evenly.
7. Troubleshooting
- Trimmer not turning on: Ensure the trimmer is fully charged. Check the USB charging cable for damage.
