I bet when you were assembling the press you found putting the primer slide spring on to be royal pain. Hook the open end of the spring to the press, raise the arm and use a foot long piece of fishing line through the closed loop of the spring to get on the slide pin. Once on slide the fishing line out.
I don't know who thought it was a good idea to put that spring to the side of the slide facing the press instead of the outside where you could get at it without tweezers
