The G004 and H004 carry identical model names across the same Fortis lineup, but they are different production generations. Component specifications, hydraulic circuit configurations, and electrical layouts reflect the G004 build standard — not the H004 revision. If your machine's data plate or service record shows G004, this is the correct document. Applying H004 procedures to a G004 machine produces incorrect results on multiple systems.\u003c\/p\u003e\n\u003cp\u003eThree configuration variants within the G004 series carry specific service implications. The BCS designation on the S80FTBCS and S100FTBCS introduces electrical and control circuit differences from the standard FT baseline. The S120FTS short mast carries its own channel dimensions, roller clearance values, and cylinder stroke data. The S120FTPRS proportional hydraulic control valve requires a post-reassembly calibration procedure that does not exist on standard control valve variants. All three are documented separately where their specifications diverge.\u003c\/p\u003e\n\u003ch2\u003eManual Technical

Check the data plate on your machine or your parts and service records. G004 on the plate means this document. H004 means the separate H004 publication. Using the wrong generation document produces incorrect component values on hydraulic, electrical, and mechanical systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the S120FTPRS proportional valve really need calibration after reassembly?\u003c\/strong\u003e\u003cbr\u003eYes. The proportional control valve on the S120FTPRS requires a specific calibration sequence after any disassembly and rebuild to restore correct hydraulic response characteristics. This step is not present in standard control valve repair references and is documented in full within this manual.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the BCS variants covered differently from the standard FT models?\u003c\/strong\u003e\u003cbr\u003eYes. The S80FTBCS and S100FTBCS carry electrical and control circuit configurations that differ from the standard FT baseline. The BCS-specific circuit procedures are documented separately within the electrical section so fault tracing on these variants uses the correct references rather than the standard FT wiring layout.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat fuel system types are covered?\u003c\/strong\u003e\u003cbr\u003eLPG, petrol, and diesel configurations are all covered with independent fuel system procedures for each — calibration data specific to the G004 engine installation, not carried over from related series.\u003c\/p\u003e","brand":"Manuals Kart","offers":[{"title":"Default Title","offer_id":52223304302868,"sku":null,"price":47.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0868\/2133\/9412\/files\/hyster-fortis-s80ft-s100ft-s120ft-s80ftbcs-s100ftbcs-s120fts-s120ftprs-g004-4-wheel-cushion-tire-lift-trucks-pdf-repair-service-manual.jpg?v=1773324558","url":"https:\/\/manualskart.com\/products\/hyster-fortis-s80ft-s100ft-s120ft-s80ftbcs-s100ftbcs-s120fts-s120ftprs-g004-4-wheel-cushion-tire-lift-trucks-pdf-repair-service-manual","provider":"Manuals Kart","version":"1.0","type":"link"}
