How to use

Ensure the trimmer is charged or connected to AC power before use. Select the desired length setting using the adjustment mechanism to match the required trim length. Move the trimmer slowly against the direction of hair growth with light, even pressure to achieve an even result. For edging and detail work, use shorter settings and controlled strokes. After trimming, switch off the device and follow cleaning instructions provided by the manufacturer to remove hair debris.

Recommendations

For consistent results, start with a longer length setting and reduce incrementally until the desired look is achieved. Regularly clean the cutting head and charge the Lithium‑Ion battery according to manufacturer guidance to maintain performance. Use the AC option for extended sessions to avoid interruptions.
