SO just to ask... The door has two special bolts, one at the front and one at the back, thr front one doesn't get a mention. On mine its a normal thread with a flat head slot in which then has a 12mm hex nut tieing it to the door frame, I gave it a few twists clockwise but didn't see any results. DO I need to unscrew the bolts above it and then use the adjuster bolt? As usual the guide says what to do without saying what to do.
