Komatsu WA180-3 Wheel Loader Operation and Maintenance Manual (PEN00257-00)

On a WA180-3 loader that spends its life in gravel pits, yards, and light quarry work, this Operation and Maintenance Manual is what we lean on to keep it ready every morning. It walks you through how to run the machine without abusing it and how to set a steady service rhythm so you’re not wrenching on it when you should be loading trucks. When, for example, the loader starts feeling “soft” on the lift or the steering gets a bit loose, this is the book we use to trace the issue back to basic checks, adjustments, and scheduled maintenance you might have missed.

Applications & Use Cases

Plan preventive maintenance so filters, belts, and wear parts get attention before they sideline the loader.
Set a realistic service schedule around your shifts and environment—dusty, muddy, or cold-weather work.
Trace early signs of wear, like sluggish hydraulics or uneven tire wear, to the right inspection points.
Verify daily and weekly checks operators should do to catch leaks, loose fasteners, or contamination.
Minimize downtime by using the manual as a step-by-step guide when you return the machine to service after repairs.

FAQ

Q: Can I use a digital copy of this manual on a tablet in the field?

A: Yes, it’s handy on a tablet; just bookmark key pages and use search to jump to specific systems or checks.

Q: Is it worth printing parts of this manual?

A: Many shops print the inspection and service pages, laminate them, and keep them in the service truck for quick reference.

Safety Note

Always follow the manual’s lockout, support, and engine shutdown instructions before inspecting or servicing the loader.
