What sort of adjustment are you talking about?
You tend to need very specialised equipment to adjust anything on mirror shutters.

Sorry I should have been more clear, by mirror I mean shutter angle...180 degrees etc.

Ah right, much easier!
It's pretty straightforward, rotate the mirror so the 3 settings are visible through the lens port, hold the hub with your finger to keep the mirror still, then insert a 2mm Allen key into the hole.
Very important now is to depress the key before turning, you should feel a slight spring pressure. Keep turning and rotating the plate until it clicks into the next position.
If you're turning the key but nothing is happening, unfortunately the little gear inside has been stripped, which is easy to do if you don't depress it first. The camera then needs to see a doctor.
If you own a BL I'd highly recommend getting Jon Fauer's "Arri 35 Book".

By the way Dom, is there such a thing as an HD video tap for the BL4?
