Carl zeiss 80mm 2.8 Hasselblad - Problem

This is my firs post, and sadly it is my big problem. I just bought Carl Zeiss 80mm f2.8, chrome version - the one with synchro-compur. My intension was to buy adapter and mount it to my canon 60d. So i open the box and try to play with new toy. First I couldn't do anything with it, it was fully open curtain and the blades. I was moving aperture ring but diaphragm stay fully open. And then I find small (I don't know what see picture - green arrow) and press, then it was sound zzzzzzzz. After than curtain was closed, and when I was able to move aperture ring, iris diaphragm was moving normally. So I was thinking that I was going to right direction. I was continuing to play, trying now to open curtain. Unfortunately after 15 min aperture ring stuck, first I couldn't open more than 5.6, then more, at the end it is fully closed as you can see in the picture. So what to do? Is it broken, just stuck or what? I could open it, if it is necessary, i fixed tessars and pancolars. Anyone any idea?

I don't have experience with this type of lenses, but common sense tells me it has a built-in shutter that must be cocked before firing. I can see a slotted screw on the back on the lens; probably, this screw was driven by the camera motor to cock the shutter after every shot.

Sounds correct to me, shutter must be cocked. I suppose way round this is to open the lens and remove the shutter blades.

Use a little coin, or a screwdrive, and turn that sort of screw near your green arrow. Shutter blades will open, but iris will be locked at full aperture.

Hmm, sounds better to sell it and get a similar lens without a shutter, a CZJ Biometar perhaps.

Thank you for help but,
first I try ti rotate screw iangreenhalgh1, it was realy need forse screw almous rotate but go beck in starting position like in photo. If I use to much force I think il will brake down. In manual for 500c it is writen that when not point the red point it is re-cocked. I understood that maybe this is position to mount it on 500c body but why the aparature ring is stuck. The best solution is to sell it but firs I have to fix it. Anyone manual for repair?

Looking at the black button that you have pointed out it looks to me like it has a collar surrounding it which doesn't appear in the best of health, it looks either to be broken in two or if meant to be in two halves then appears to be misaligned.

Edit, Can the previous owner not help ?

In the end after consulting owner, couple of groups, forums and read user manual for 500c I figure it out who this lens work. Everything that I mentioned is ok, and normal with this lens.
