5. Operation
Attaching Guide Combs
To adjust hair length, select one of the five guide combs (1mm, 2mm, 3mm, 4mm, 5mm). Align the comb with the trimmer blade and snap it into place. Ensure it is securely attached before use.

Powering On/Off
Locate the power switch on the side of the trimmer. Slide it to the 'ON' position to activate the trimmer. Slide it back to the 'OFF' position to turn it off.
Trimming Hair and Beard
Hold the trimmer with the blade flat against the skin or at the desired angle. Move the trimmer slowly against the direction of hair growth for an even cut. The zero-gapped ceramic and DLC blades are designed for precise lines and close trimming.

6. Maintenance
Cleaning the Blades
After each use, turn off the trimmer and remove any attached guide comb. Use the provided cleaning brush to remove loose hairs from the blades. For a more thorough cleaning, the blades can be carefully detached and rinsed under running water, ensuring they are completely dry before reattaching.
Lubrication
Apply a few drops of the included lubricating oil to the blades regularly, especially if the LED display shows a lubricant reminder. This helps maintain blade sharpness and ensures smooth operation.

7. Troubleshooting
- Trimmer not turning on: Ensure the battery is charged. Connect the trimmer to the charger and allow it to charge for at least 30 minutes before attempting to power on again.
- Poor cutting performance: Clean the blades thoroughly to remove any trapped hair or debris. Apply lubricating oil to the blades. If performance does not improve, the blades may need replacement.
- Trimmer pulls hair: This often indicates dull blades or insufficient lubrication. Clean and oil the blades. If the issue persists, consider replacing the blades.
- LED display not working: Ensure the trimmer is charged. If the issue continues, contact customer support.
