The plasticised, non-tearable paper that is hacked into the blades is removed in the same way as the blade change. Tearing it out - as said in the video - often does not work or damages the mechanics.
Since I had to figure it out myself, at least I'm helping others. This one needs 9mm blades (1-11-300). Thanks again for no support dear Digitec team. Unfortunately, I would have managed without you - exemplary!
