6. Setup
6.1 Initial Charging
Before first use, fully charge the hair clipper. Connect the USB charging cable to the Type-C port on the bottom of the clipper and plug the other end into a compatible USB power source (e.g., laptop, power bank, car charger, or a USB wall adapter). The intelligent LED display will show the charging status and battery percentage. A full charge takes approximately 3 hours.

6.2 Attaching Guide Combs
To achieve desired hair lengths, select one of the provided guide combs. Align the comb with the clipper blade and push it firmly until it clicks into place. Ensure it is securely attached before turning on the clipper. To remove, gently pull the comb away from the blade.

7. Operation
7.1 Powering On/Off
To turn on the clipper, slide the power button located on the side of the device upwards. The LED display will illuminate, showing the current battery percentage. To turn off, slide the power button downwards.
7.2 Hair Cutting
- Ensure the hair is clean and dry.
- Attach the desired guide comb for the length you wish to cut. For a very close trim (less than 0.5mm), use the clipper without a guide comb.
- Hold the clipper with the blade facing downwards.
- Start cutting from the bottom of the head, moving upwards against the direction of hair growth.
- Use slow, even strokes. Do not force the clipper through the hair.
- Regularly check the LED display for battery level and oil indicator.

- POWER LEFT%: Shows the remaining battery charge as a percentage.
- Charging Indicator: Appears when the clipper is connected to a power source and charging.
- Oil Indicator: Reminds you to lubricate the blades for optimal performance and longevity.
8. Maintenance and Cleaning
Proper maintenance ensures the longevity and performance of your hair clipper.
8.1 Cleaning the Blades
- Turn off the clipper and disconnect it from the power source.
- Remove any attached guide comb.
- Use the provided cleaning brush to brush away loose hairs from the blades and the clipper head.
- For a more thorough cleaning, the blades can be carefully detached (refer to specific instructions if provided in the physical manual for blade removal).
8.2 Lubricating the Blades
After every few uses, or when the oil indicator appears on the display, apply a few drops of lubricating oil (if included) to the blades. Turn on the clipper for a few seconds to allow the oil to distribute evenly. This helps maintain blade sharpness and smooth operation.
8.3 Storage
Store the clipper in a dry place, away from direct sunlight and moisture. Use the integrated storage hook for convenient hanging.

9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clipper does not turn on. | Battery is depleted. | Charge the clipper fully (approx. 3 hours). |
| Clipper not charging. | USB cable or power source issue. | Ensure the USB cable is securely connected. Try a different USB port or power adapter. |
| Poor cutting performance / pulling hair. | Blades are dull, dirty, or not lubricated. | Clean the blades thoroughly with the brush. Apply lubricating oil to the blades. If blades are dull, consider replacement (contact support). |
| Clipper runs slowly or makes unusual noise. | Hair buildup in the motor or low battery. | Clean the clipper thoroughly. Ensure the battery is fully charged. |

10. User Tips
- For best results, always start with clean, dry hair.
- When cutting, move the clipper against the direction of hair growth for a more even cut.
- Use shorter guide combs first, then gradually move to longer ones if you're unsure about the desired length.
- Regularly oiling the blades (especially after cleaning) will significantly extend the life of your clipper and ensure smooth operation.
