Komatsu WA100-1 Wheel Loader Operation and Maintenance Manual (SEAM04160104)

The WA100-1 is a compact wheel loader that spends its life in tight yards, small quarries, and construction sites, loading trucks and feeding hoppers all day. This Operation and Maintenance Manual helps you set a steady service rhythm, so you’re not guessing when to grease, inspect, or adjust. Out on a muddy site, if the loader starts feeling sluggish or warning lights pop up, this is what you’d use to trace basic causes, verify you’re operating it correctly, and decide if it’s a simple check or needs a shop visit.

Applications & Use Cases

• Plan daily, weekly, and seasonal checks so the loader is ready for long shifts without surprise breakdowns.
• Follow the recommended inspection logic to spot early wear on pins, hoses, and tires before they sideline the machine.
• Use the operating guidance to keep the loader stable when working on slopes, in soft ground, or around tight stockpiles.
• Coordinate preventive maintenance with your work schedule to minimize downtime and avoid rushed emergency repairs.
• Train new operators on proper warm-up, shutdown, and basic care so they don’t shorten the machine’s life.

FAQ

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

Safety Note
