For a quick and convenient shave, use the shaver on dry skin. Ensure your face is clean and dry before shaving.

5.4 Key Features for an Effective Shave
- 3-Link Suspension Head: Three independent cutting elements float up and down to adapt to the contours of your face, ensuring close skin contact.
- Deep Catch Foil: Features 899 different mesh patterns within a single foil to capture hairs growing in various directions from the root across the entire shaving head.
- Comfort Inner Blade: The 49-degree acute-angled inner blade is cut 2 microns inward at the tip, minimizing contact with the skin and allowing for a close shave in one stroke without irritation.
- S-shaped Long Hair Trimmer: Smoothly captures stubborn, hard-to-catch long hairs and effectively cuts them.
- Active Tighting System: An integrated foil and inner blade cassette eliminates gaps between the foil and inner blade, ensuring efficient and reliable cutting of captured hairs.

6. Cleaning and Maintenance
6.1 Cleaning Under Running Water
The shaver head and body are fully washable. After each shave, switch on the shaver and rinse the shaver head under hot running water until all residue has been removed. You can use liquid soap without abrasive particles.

6.2 Deep Cleaning
For a more thorough cleaning, remove the foil and cutter cassette and tap out any trapped hairs. Use the small cleaning brush provided to remove stubborn hairs from the inner parts of the shaver head. Do not use the brush on the foil itself, as this may damage it.
6.3 Replacing the Shaver Parts
To maintain 100% shaving performance, replace the integrated foil and cutter cassette (part F/C21B) approximately every 18 months, or when the parts are worn. The replacement process is simple:
- Press the release buttons (if applicable) or gently pull the old cassette upwards to remove it.
- Snap the new F/C21B cassette into place until it clicks.
