Komatsu WA800-8E0, WA900-8E0 Wheel Loader Operation and Maintenance Manual (EENAM03940)

These WA800-8E0 and WA900-8E0 loaders live in hard places—quarries, mines, heavy production yards—where they’re loading rock and ore all day. This operation and maintenance manual is what I’d keep handy to set up a sane service rhythm, so the machine doesn’t quit mid-shift. When an operator reports sluggish lift or odd noises on a cold start, I use this book to walk through the basic checks, verify daily/weekly items were done right, and decide if it’s a simple adjustment or needs a deeper tear-down.

Applications & Use Cases

Plan preventive maintenance so you can schedule downtime between production runs instead of during them.
Set up operator routines for walk‑around checks, fluid level inspections, and warm‑up habits that extend component life.
Trace early wear signs like unusual vibration, heat, or leaks back to likely causes before they become failures.
Verify adjustments after filter changes, linkage work, or tire swaps so the loader stays stable under full bucket loads.
Train new operators on correct startup/shutdown procedures and basic care without overwhelming them.

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 while parked safely.

Q: Is it worth printing certain pages?

A: Many techs print the inspection and service checklists to mark up in the shop and on the jobsite.

Safety Note

Always follow the manual’s lockout, parking, and pressure‑relief steps before inspecting or servicing the loader.
