I'm trying to track down a hydraulic diagram or pump manual (PDF) for a Sumitomo S280F2 and am not having much luck so far. I recently got my hands on one and want to better understand the hydraulic system layout, pump specs, and troubleshooting basics before I start digging into any repairs. Even a similar model manual or partial diagram would help a lot. If anyone has a PDF manual, schematic, or knows a reliable source (paid or free), I'd really appreciate it. Also open to tips on where you usually find older Sumitomo manuals.
