6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your KEMEI 1743 clipper.
6.1 Cleaning the Blades
- Turn off and unplug the clipper.
- Use the provided cleaning brush to remove any loose hairs from the blades and the clipper head.
- For a more thorough clean, the blades can be rinsed under running water. Ensure the clipper body remains dry.
- Allow blades to air dry completely before reattaching or storing.
6.2 Oiling the Blades
After every few uses or after cleaning, apply 1-2 drops of lubricating oil (included) to the blades. Turn the clipper on for a few seconds to distribute the oil evenly. This helps maintain blade sharpness and reduces friction.
