Hi Dimitri,
don't worry, you'll fix that. So, thats the photo i related to. I modified it to show what i think to have translated
red arrow, thats the 2nd bolt from behind, unfasten it until it is flush with the green line (or the nut, when you watch the real part)
yellow arrow: thats why i ment, that you didn't follow the instructions, but as i realized at the second view, i was wrong. The magenta arrow shows, that you did right.
Harry.
