When you put the new tube into an 8000/8100/8500 AC machine, do you tighten the "factory set" bolts (sheimflugish) all the way down or are they supposed to be set some other way? I don't mean the bolts that are normally used for sheimflug adjustments but the other ones that look exactly the same with just the one (r/b) or two (g) that have a red cap over them and the manuals say "don't touch".

Thanks,
