4. Setup
- Unpack: Carefully remove all components from the packaging. Inspect the clipper and accessories for any damage.
- Initial Charge: Before first use, fully charge the clipper. Connect the USB charging cable to the Type-C port on the clipper and plug the other end into a compatible USB power source. The LCD display will show the charging status. A full charge takes approximately 2 hours.
- Lubricate Blades: Apply a small drop of the included lubricating oil to the blades before the first use and after each cleaning to ensure smooth operation and longevity.
- Attach Guide Comb (Optional): If a specific hair length is desired, select one of the three guide combs (1.5mm, 3mm, or 4.5mm) and securely attach it to the clipper head. For zero-gap trimming, use the clipper without a guide comb.
