Komatsu PC150-6K, PC150LC-6K Hydraulic Excavator Operation and Maintenance Manual (EEAD008801)
These PC150-6K and PC150LC-6K excavators usually live in dirt and rock all day—trenching, loading trucks, and cleanup around construction sites and quarries. This operation and maintenance manual is what I’d keep in the cab or shop to set a sane service rhythm and keep the hydraulics and engine from becoming surprise downtime. When, for example, the swing feels lazy or the boom starts to drift, I use this book to verify daily checks, trace simple causes, and decide what needs a mechanic and what the operator can correct on the spot.
Applications & Use Cases
- Plan preventive maintenance so filters, belts, and wear items are checked before they become failures.
- Set daily/weekly inspection routines for walk-arounds, leak checks, and loose hardware.
- Guide operators on proper warm‑up and shutdown to reduce thermal stress and extend component life.
- Verify fluid levels and grease points in the right order to speed up servicing between shifts.
- Support troubleshooting of basic performance complaints before calling in full diagnostics.
FAQ
Q: Can I use this manual on a tablet in the field?
A: Yes, it’s practical to keep a digital copy for quick search, then screenshot or bookmark the pages you use most.
Q: Is it worth printing parts of it?
A: Many techs print the inspection and service pages, laminate them, and hang them in the shop or fuel bay.
Safety Note
Always follow the manual’s safety instructions and lockout procedures before inspecting or servicing the machine.
