New Holland ec35mini-excavator relief valves

Anyone have an ec35 mini-x or manual on one? I am trying to identify where the relief valves are to clean them out. Had rotary transfer seals disintegrate and go through the system. After replacement certain controls are weak and apparently not operating at pressure. The filter system is poorly designed also, the filter is internal with a bottom drain to tank; when you pull the filter, particles can drain into the unfiltered system and suck back through to the valves. I know it will take some time, flushes, filters, and cleaning to straighten it out, however my hydraulics experience is llimited and I haven’t identified where the relief valves are. I have the parts list schematic but the actual application and where they are placed on the machine are quite different.
