How do I open lens to focus, Fujinon W 150mm 5.6?

Hello, I am new to 4x5 photography, I have been using other formats for years. I just got my darkroom back up and running, got a 4x5 enlarger and finally a camera, a Toyo View D45M. The lens is a Fujinon W 150mm 5.6 with a Seiko shutter. I don't see any way to open the lens for focusing other than using the B setting on the shutter. There is another lever on the lens that I don't know what it does, it doesn't seem to move and I don't want to break it. Any help is appreciated.

That lever you don't know what it does...... push it inward rather than flipping it sideways. I believe the lens must be cocked first, also.

mdarnton is almost right on. Cock the shutter then pull the "lever" with the black dot out.

Jeff is closer than I was, but it's the lever next to the one with the black dot. The black dot is the cocker. We'll get it eventually.

Thanks that worked with pulling that one out, I've noticed if I don't push it back in hard the shutter sticks, Wish I had a copal shutter, this one seems a little rough. It's my first lens so I plan on buying a Schneider or Rodenstock 210mm and then a super angulon 90mm, maybe another Fujinon with a copal shutter.

Yeah, this feels familiar with rough uncommon shutters.

I found the preview lever thingy on my Synchro Compur 1 to be very awkward and i use T/B mode to focus, it just worked easier.

I have one Seiko with that push-pull lever like that and it sticks sometimes, even after I opened it up to see if there was a problem. I notice my later year Seiko shutters all have a side-to-side lever which seems to work better.
