First of all want to say "Hi" :)

I am facing an issue with proper cutting..
Depends of material:
- paper is OK
- heavyweight paper - NOT OK - after cutting when you check dimensions cards which are in lower part os stack they get bigger size.

I assume some problem with hydraulics but can't find diagrams.
I have read in this forum that the pressure valves are doubled for safety reasons, so as I understand it is hard to diagnose the failure of the valve.

Can someone provide diagrams of hydraulic system??
Maybe some clues to fix my problem?? :)

Stay safe :) and healthy
