These PC210 and PC240 series Komatsu excavators spend their lives loading trucks, trenching, and handling heavy digs in dusty sites, wet ground, and tight urban jobs. This Operation and Maintenance Manual is what I’d keep in the cab or shop office to set a steady service rhythm and avoid surprise breakdowns. When a boom movement starts to feel sluggish or the swing gets a bit jerky, I’d use this book to walk through basic checks, confirm daily and periodic inspections, and decide what needs attention before it turns into real downtime.
Applications & Use Cases
FAQ
Q: Can I keep this manual on a tablet in the cab?
A: Yes, it’s practical to use digitally; you can zoom diagrams and quickly search terms while the machine is parked.
Q: Is it worth printing certain pages?
A: I’d print the routine inspection and service pages, laminate them, and hang them in the shop or service truck.
Safety Note
Always follow the manual’s lockout, support, and pressure‑relief steps before inspecting or servicing any part of the excavator.
