Connect the charging cable to the clipper's charging port and plug it into a suitable power source. The LED indicator will show charging status. The intelligent charging technology automatically stops charging when the voltage reaches 6V to prevent overcharging.

5.2 Attaching Guide Combs
Select the desired guide comb for your preferred hair length. Align the comb with the clipper blades and push it firmly until it clicks into place. To remove, gently pull the comb away from the blades.
5.3 Blade Adjustment (Zero-Gapping)
The blade lever allows for precise adjustment of cutting lengths from 0.5mm to 2mm without a comb. For zero-gapping, which provides the closest cut, consult a professional or refer to detailed online tutorials. This process involves carefully aligning the fixed and moving blades to minimize the gap between them.
6. Operating Instructions

- Select and attach the appropriate guide comb for your desired hair length.
- Adjust the blade lever to fine-tune the cutting length if not using a comb.
- Turn on the hair clipper using the power button.
- Pass the clipper through clean, dry hair against the direction of hair growth for an even cut.
- For detailing or fading, use the adjustable blade lever and smaller guide combs as needed.
- Turn off the clipper using the power button when finished.
- Clean the blades after each use (refer to Maintenance section).

8. Maintenance
8.1 Cleaning the Blades
- Turn off and unplug the clipper.
- Use the cleaning brush to remove loose hair from the blades and the area around them.

- Do not rinse the entire clipper under water.
8.2 Oiling the Blades
After each cleaning or at least once a month, apply a few drops of the provided blade oil to the teeth of the blades. Turn the clipper on for a few seconds to distribute the oil evenly. This helps maintain blade sharpness and reduces friction.

Store the clipper in a cool, dry place, away from direct sunlight and moisture. Ensure it is turned off and unplugged before storing.
