Setup
- Initial Charge: Before first use, fully charge the clipper for approximately 3 hours. Connect the USB charging cable to the clipper and a suitable USB power adapter (not included). The LCD display will indicate charging status.
- Attaching Guide Combs: Select the desired guide comb for your preferred hair length. Align the comb with the clipper blade and push it firmly until it clicks into place. Ensure it is securely attached before use.
- Blade Adjustment: The clipper features an adjustable blade lever on the side. Move the lever up or down to fine-tune the cutting length without a guide comb, or to adjust the base length when a comb is attached.
Operating Instructions
- Turning On/Off: Press the power button to turn the clipper on. Press it again to turn it off. The LCD display will show battery level and speed settings.
- Trimming Hair:
- Ensure hair is clean and dry.
- Start with a longer guide comb if you are unsure of the desired length.
- Hold the clipper with the blade teeth pointing upwards.
- Move the clipper against the direction of hair growth, using smooth, even strokes.
- For blending and tapering, use different guide comb lengths or adjust the blade lever.
- Beard Trimming:
- Use a suitable guide comb for beard length.
- Trim in the direction of hair growth for a more even trim.
- For detailing and sharp lines, remove the guide comb and use the adjustable blade at its shortest setting (ensure caution).
Maintenance
Proper maintenance ensures the longevity and optimal performance of your clipper.
- Cleaning the Blades: After each use, turn off and unplug the clipper. Use the provided cleaning brush to remove any loose hairs from the blades.
- Oiling the Blades: Apply a few drops of the included lubricating oil to the blades after every few uses, or if the clipper starts to pull hair. Turn the clipper on for a few seconds to distribute the oil evenly. This helps maintain blade sharpness and reduces friction.
- Cleaning the Body: Wipe the body of the clipper with a soft, damp cloth. Do not use abrasive cleaners or immerse the clipper in water.
- Storage: Store the clipper in a dry place, away from direct sunlight and out of reach of children. Use the blade guard to protect the blades when not in use.
