- Shaving cassette should be changed every 18 months
- The 53B shaving cassette snaps on and off for easy exchange.
- Pull the shaving unit upwards to remove it from the shaver body.
- Push down on the new shaving head until it snaps into place.
- Maintain 100% shaving performance by replacing the shaving cassette when the replacement symbol
lights up on the shaver, or when the cassette is worn out. The replacement symbol will remind you during
the next 7 shaves to replace the shaving cassette, then the shaver will automatically reset the display.
After you have replaced the foil and cutter cassette, use a pointed object to push the reset button for
at least 3 seconds to reset the counter. While doing so, the replacement light blinks and goes off when
the reset is complete. The manual reset can be done at any time.
