Looking for service manual Summa F1612

0.6MPa for the main one and 0.125MPa for the secondary.
That is what our Summa tech told us when he came out to set up the machine and the secondary wont go down to .125 (air just blows by and out). Summa guy said the pressure regulator is bad and need replaced before using router. We got the new part and the behavior is exactly the same (air blow by and wont go down to .125) with the old and the new part. I assumed this setting cannot be correct is why I was looking for the service manual. So what's next to troubleshoot if the pressure regulator will not go down to .125?

If I set the secondary to right around .6MPa it will stop and hold air, anything lower and it just blows by and wont hold air, so we can't get it down to .125. While the router is running, the lowest the pressure will go is about .45.

Is it installed the right way?
Assuming yes. We purchased this cutter second hand and the previous owner used it mostly for the router function. The Summa tech who came out to verify everything and test the machine and train us, ran the burn in on the router and did some test cuts. The router works, but the pressure regulator won't go down to .125. The Summa tech told us not to use the router in production until the pressure regulator was replaced.

I don't know.. It's just a off the shelf regulator. This shouldn't be too difficult to figure out. No service manual is going to help you, it's just regular air.

Some sort of manual would be nice so I can verify the connections to the HF router. There are two air lines going to the router. A clear blue line goes into the top of the router and a solid black line goes into the base of the router. The clear blue line comes out of pressure switch #5 under the table and has no air pressure regulator. The black line comes out of pressure switch #6 under the table and has the pressure regulator in-line. Could the original installer have reversed these lines? Idk, and without a full service manual I cannot verify.
