Komatsu 930E-2 Dump Truck Operation and Maintenance Manual (CEAD012000)

On a 930E-2, you’re hauling big loads in a mine or large earthmoving site, running long shifts on rough haul roads. This Operation and Maintenance Manual is what I use to set a steady service rhythm, so the truck stays predictable and doesn’t surprise you mid-shift. Say a driver reports the truck pulling on a grade and the temps creeping up; I’ll go to this book to verify the right daily checks, trace possible causes, and decide if it’s safe to run until the next scheduled stop or if we park it now.

Applications & Use Cases

Plan preventive maintenance so inspections, filter changes, and adjustments line up with your production schedule.
Standardize daily walk-arounds for operators, so they catch leaks, loose hardware, or tire issues before they become failures.
Verify correct operating procedures to avoid abusing the driveline, brakes, and suspension on long downhill hauls.
Trace early warning signs like unusual noises, warning lights, or slow response, and decide what to inspect first.
Train new operators and supervisors on how to run and care for the truck without shortening its life.

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 search terms, just keep the device protected from dust and vibration.

Q: Is it worth printing sections of this manual?

A: I’d print the daily/weekly check pages and keep them in the service truck so techs can mark items off during rounds.

Safety Note

Always follow the manual’s lockout, parking, and support procedures before inspecting or working under the truck.
