Operating Instructions
1. Power On/Off
Press the Power switch button (labeled with a power icon) to turn the clipper on or off. The LED display will illuminate when the device is active.
2. Adjusting Cutting Length (Fine-tuning)
Use the Head adjusting button (lever control blade) to fine-tune the cutting length. This allows for adjustments from 0.8mm to 2.0mm, typically referred to as the fourth gear fine-tuning. This is ideal for precise fades or very short trims.
3. Adjusting Speed
The clipper features a 5-speed transmission. Use the fast/slow buttons (plus and minus icons) to adjust the motor speed. The LED display will show the current speed setting. The third gear speed is adjustable, providing control during the hairdressing process.

4. Hair Cutting
Hold the clipper with the blade flat against the hair. Move the clipper slowly against the direction of hair growth. For best results, ensure hair is clean and dry. Use the guide combs for uniform length. For detailing, remove the guide comb and use the fine-tuning lever.
5. Digital Display
The integrated LCD provides real-time information, including battery level and current speed setting, allowing for precise control during use.
Maintenance
1. Cleaning the Blade
After each use, turn off the clipper and remove any attached guide comb. The body is removable for easier cleaning. Use the provided cleaning brush to remove loose hairs from the blade and the clipper body. For a more thorough clean, the metal trimming head can be carefully detached and rinsed under running water. Ensure the blade is completely dry before reattaching and storing.
2. Lubrication
Regularly oil the blades to maintain optimal cutting performance and prolong the life of your clipper. Apply a few drops of clipper oil (not included due to international transport regulations) to the teeth of the blade while the clipper is running for a few seconds. Wipe off any excess oil.
3. Storage
Store the clipper in a dry, cool place, away from direct sunlight and moisture. Keep it out of reach of children.
Troubleshooting
- Clipper not turning on: Ensure the battery is charged. Connect the clipper to the charger and allow it to charge for at least 30 minutes before attempting to turn it on again.
- Poor cutting performance: Check if the blades are clean and free of hair debris. Lubricate the blades if they appear dry. Ensure the guide comb is correctly attached.
- Unusual noise: Clean and lubricate the blades. If the noise persists, ensure no foreign objects are lodged in the blade mechanism.
- Battery not charging: Verify that the charging cable and adapter are properly connected to both the clipper/charging base and the power outlet. Ensure the power outlet is functional.
