How to use

Charge the trimmer fully before first use according to the manufacturer’s instructions. Select and attach the desired comb or the OneBlade attachment depending on the intended length and finish. Switch the device on and move the trimmer gently against hair growth for an even cut; for very short lengths use the 0.2 mm setting and for longer cuts attach the appropriate comb. Use the OneBlade attachment to outline and refine edges, working slowly along contours for precise results. After trimming, switch off the device and clean removable combs and blades as instructed in the user manual to maintain performance.

Recommendations

For best results, perform trimming on dry hair and take multiple light passes rather than a single aggressive cut. Regularly clean and dry attachments after use and charge the battery periodically to preserve battery life. Replace worn blades or the OneBlade head according to usage frequency to ensure continued cutting accuracy.
