Oiling the Blades
For optimal performance and longevity, it is essential to oil the blades before each use. Apply a few drops of the provided blade oil across the top of the blades. Turn on the clipper for a few seconds to distribute the oil evenly, then wipe off any excess with a clean cloth.

Operating Instructions
Attaching Guide Combs
Select the desired guide comb based on the hair length you wish to achieve. The kit includes 12 color-coded guide combs ranging from 1/16" (1.5mm) to 1" (25mm). Align the comb with the clipper blade and snap it securely into place. Ensure it is firmly attached before use.

Adjusting the Taper Lever

General Haircutting Tips
- Always start with a longer guide comb than you think you need, and gradually work your way down to shorter lengths.
- Cut against the direction of hair growth for an even cut.
- Use the included hair clips to section off hair, making it easier to manage.
- For fading, use the taper lever to create smooth transitions between different hair lengths.
- The clipper is designed for use on dry hair for best results.

Maintenance
Cleaning the Blades
After each use, turn off the clipper and remove any attached guide comb. Use the provided cleaning brush to remove loose hairs from the blades. For a more thorough cleaning, you can carefully detach the blade set (refer to the user manual for specific instructions) and rinse it under running water, ensuring the main body of the clipper does not get wet. Allow blades to air dry completely before reattaching.
Oiling the Blades
Regular oiling is crucial for maintaining blade sharpness and preventing rust. Apply a few drops of the included blade oil to the blades before and after each use. This ensures smooth operation and extends the life of your clipper.
Storage
Store the clipper and all accessories in a dry, safe place away from moisture and extreme temperatures. Ensure the blade guard is in place to protect the blades when not in use.
Troubleshooting
- Clipper is pulling hair: This often indicates low battery or dull/un-oiled blades. Ensure the clipper is fully charged and the blades are clean and properly oiled.
- Clipper not turning on: Check if the battery is charged. If not, connect to the charger. Ensure the power button is pressed firmly.
- Uneven cut: Ensure the guide comb is securely attached and that you are cutting against the direction of hair growth. Clean any hair buildup from the blades and comb.
- Excessive noise or vibration: Ensure the blades are clean and properly oiled. If the issue persists, contact customer support.
