7. Maintenance
7.1 Cleaning
- Turn off the trimmer and detach the head after each use.
- Use the provided cleaning brush to remove hair clippings from the blades and inside the trimmer head.
- The trimmer heads may be rinsed under running water for thorough cleaning. Ensure the main unit is not submerged in water.
- Allow all parts to air dry completely before reattaching or storing.
7.2 Oiling Blades
- After cleaning and drying, apply a small drop of the provided oil to the blades.
- Turn on the trimmer for a few seconds to distribute the oil evenly. This helps maintain blade sharpness and prevents rust.
7.3 Storage
Store the grooming kit and its accessories in a cool, dry place, away from direct sunlight and out of reach of children.
8. Troubleshooting
- Trimmer not turning on: Ensure the battery is charged. Connect the USB cable and charge for 2 hours.
