Welcome to the forums. To begin with, let's not resurrect old threads. Start a new thread in the appropriate section. In addition to that, swing over to new member introductions, say hi and what you do as well as where you are in the world. Aside from that, keep your information request a little more narrowed down. For example, "I need to know how the boom suspension valves are plumbed in" We can't host an entire service manual, but we can piece out what you're after. Once again, welcome.
Hello again I deal with the repair of working machines, here I am honestly connecting additional controls, so I need a connection diagram, since the machine has ls control of the hydraulic pump

So you are adding a 3rd function to the machine? Again, let's start a new thread to get more attention.
That's how I add the 3rd command, so I'm interested in where to connect pl, ps and lsp and is there anything else that needs to be connected
Please see attached. The LS line from the main control valve will enter into 3rd function valve. Line that originally went to main control valve gets pulled back and connects to other side of 3rd function valve.
