Komatsu WA470-8 Wheel Loader Operation and Maintenance Manual (TEN01146-00)

Running a WA470-8 all day in a quarry, feed pile, or load-out yard is hard on the machine, and this Operation and Maintenance Manual is what I lean on to keep it reliable between major shop visits. It walks you through the daily and scheduled checks so you can spot loose pins, contaminated filters, or cooling issues before they turn into downtime. If, for example, the loader starts running hotter after long uphill hauls, this is the book I’d use to verify inspection points, clean-out routines, and basic adjustments before calling in a bigger repair.

Applications & Use Cases

• Set up a preventive maintenance rhythm so inspections and services are done on time, not when something fails.
• Trace early wear signs on pins, bushings, tires, and linkage before they affect bucket control or stability.
• Verify fluid and filter service steps to avoid air in systems or leaks after a change.
• Plan work around service intervals so the loader is down when you choose, not when it decides.
• Train new operators on correct warm-up, shutdown, and daily walk-around habits that extend component life.

FAQ

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

A: Yes, it’s handy to have a digital copy for quick searching, but I’d still keep a printed version in the shop for greasy-hands work.

Q: Is it worth printing the whole manual?

A: I usually print the routine service and inspection pages, laminate them, and keep them at the service bay; the rest I leave digital for reference.

Safety Note

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