Komatsu PC900LC-11 Hydraulic Excavator Operation and Maintenance Manual (TEN01039-00)

On a PC900LC-11 that’s digging mass excavation or loading trucks in a quarry, this Operation and Maintenance Manual is what I keep handy to keep the machine earning instead of parked. It walks you through the daily and scheduled checks so you can spot loose hardware, hose chafe, or a lazy swing before it turns into a shutdown. If an operator reports slow boom response at the end of a shift, I’d use this manual to verify the right inspection points, confirm basic settings, and rule out simple maintenance issues before calling in heavier diagnostics.

Applications & Use Cases

Plan preventive maintenance so you can schedule services around production instead of reacting to breakdowns.
Set a consistent inspection routine for operators and techs, reducing missed wear points on undercarriage and hydraulics.
Trace early signs of leaks or overheating and verify simple causes before pulling components.
Align machine setup with job conditions, like long digging cycles or heavy rock work, to minimize unnecessary stress.
Train new operators on proper warm-up, shutdown, and basic care to avoid abuse-related failures.

FAQ

Q: Can I keep this manual on a tablet in the field?

A: Yes, it’s practical to use digitally; you can zoom diagrams, search keywords, and keep it in the cab or service truck.

Q: Is it worth printing sections of this manual?

A: Many mechanics print the key maintenance pages and keep them in a shop binder or jobsite box for quick, grease-proof reference.

Safety Note

Always follow the manual’s safety instructions and lockout procedures before inspecting, adjusting, or servicing this excavator.
