Ford Escort Pump 1.8TD 70CV

Very good to everyone, I have been in this for a few days and I am a bit lost ... rather I do not know where to look, so I would appreciate a help. I downloaded the Ford Escort manual in Spanish, but the question is that I download the American escort and I do not know if the European is in Spanish, I would thank you that if someone can tell me where I get it, I would help me, ask me in the Ford but as expected they have told me that they do not have it and even if they had it that if it is not known of mechanics, dangerous' is dangerous. Anyway my question is what is the screw that regulates the passage of the diesel?

Thanks in advance
