Maintenance
1. Cleaning the Blades
- Turn off the clipper and disconnect it from any power source.
- Remove the guide comb.
- Use the provided cleaning brush to remove any loose hairs from the blades and the clipper body.
- The blades are designed for washing under water. You can rinse the blade head under running water. Ensure the clipper body does not get submerged.
- Allow the blades to air dry completely before reattaching the protective cover or storing.
2. Lubrication
- After cleaning and drying, apply a small drop of the lubricating oil (included in the package) to the blades.
- Turn on the clipper for a few seconds to distribute the oil evenly. This helps maintain blade sharpness and smooth operation.
- Wipe off any excess oil with a soft cloth.
3. Storage
- Store the clipper in a dry, cool place, away from direct sunlight and moisture.
- Always attach the protective cover to the blade when not in use to prevent damage.

- Regular cleaning and oiling of the blades will significantly extend the life and performance of your clipper.
