Komatsu PC300-6 weak movement: which volume should come first?
Structure/function explains the normal system, testing/adjustment supports matched measurements and disassembly/assembly supports an agreed repair. Record the full model, serial, engine and warm/cold symptom pattern. Do not apply a PC200-7 limit to a PC300-6 because both appear in the same archive.
Coverage and edition notes
PC300-6 structure/function, testing/adjustment and disassembly/assembly are separate collected files. The inspected PC200/220-6 cover is YEBM200201 and lists model-specific serial ranges. A 102-series engine manual is not a complete PC200-7 chassis manual. Encrypted or unreadable files are not presented as verified references.

Full-document access, safety and service terms
Public HTML contains YUANJIAN-written explanations and selected catalogue metadata. Preview images are YUANJIAN-compiled index cards, not manufacturer covers or full manual pages. Complete documents are not publicly downloadable; supply depends on availability, applicability and permission. No manufacturer authorization is implied. This bilingual catalogue does not translate the complete source manuals, which include Chinese, English and scanned material.
Five-year guidance covers operation, maintenance questions and troubleshooting communication. It is not a five-year warranty and excludes free parts, consumables, freight, on-site labor and repairs. Pressure tests, electrical measurements, adjustments, lifting and disassembly require qualified technicians, safe isolation and the correct current service instructions. Do not bypass safety systems or adjust pressure from an unmatched diagram.
