- Plug the USB cable into a compatible USB power adapter (not included) or a USB port.

3.2 Attaching Guide Combs
Select the desired attachment comb (1mm, 2mm, or 3mm) for your preferred cutting length. To attach, align the comb with the trimmer blade and push it firmly until it clicks into place. To remove, gently pull the comb away from the blade.
4. Operation
4.1 Basic Trimming
Ensure the trimmer is charged and a comb is attached if desired. Turn on the trimmer using the power button. Hold the trimmer with the blade flat against the skin or at a slight angle, moving it against the direction of hair growth. For a 0mm cut, remove the attachment comb and carefully use the bare blade.

4.2 Outlining and Shaping
For precise outlining and shaping, use the trimmer without an attachment comb. The R-shaped ceramic moving blade is designed for smooth, close cuts. Hold the trimmer at an angle to create sharp lines around the hairline, beard, or mustache. Exercise caution when trimming sensitive areas or if skin conditions like pimples are present.
4.3 Corded Operation
If the battery is low or you prefer continuous power, the trimmer can be used while plugged into the charging cable. Connect the USB cable directly to the trimmer's port or use the charging pod as a pass-through.
5. Maintenance
5.1 Cleaning the Blades
Regular cleaning ensures optimal performance and longevity of your trimmer.
- Turn off the trimmer and disconnect it from any power source.
- Use the provided cleaning brush to remove loose hairs from the blades.
- For a more thorough clean, the blades can be carefully detached (refer to specific instructions if provided with the product for blade removal). Rinse the blades under running water, ensuring the trimmer body does not get wet.
- Allow blades to air dry completely before reattaching.
5.2 Lubricating the Blades
After cleaning or every few uses, apply a few drops of the provided lubricating oil to the blades. Turn on the trimmer for a few seconds to allow the oil to distribute evenly. This helps maintain blade sharpness and smooth operation.
6. Troubleshooting
- Trimmer not turning on: Ensure the battery is charged. If using corded, check the power connection.
- Poor cutting performance: Clean the blades to remove hair buildup. Lubricate the blades. Ensure blades are properly aligned.
- Trimmer making unusual noise: Clean and lubricate the blades. If the noise persists, contact customer support.
- Battery not charging: Check the USB cable and charging pod connections. Ensure the power adapter is functioning correctly.
