Komatsu WA470-6 Wheel Loader Operation & Maintenance Manual

This Komatsu WA470-6 Wheel Loader Operation & Maintenance Manual is the definitive guide for operating, inspecting, and servicing machines with serial numbers 90234 and up. Whether you run a fleet of WA470-6 loaders on a quarry, a construction site, or a material handling yard, this manual gives you the exact procedures and specifications Komatsu published for this machine. It is the same document referenced in the cab and used by technicians to keep the loader performing at its designed capability.

Form number TEN00451-00 covers the complete machine: the Komatsu SAA6D125E-5 diesel engine, the transmission and torque converter, axles, brakes, steering system, hydraulic circuits, work equipment, cab controls, machine monitor, air conditioning, electrical system, and every maintenance interval from daily checks through 8000-hour service. The manual is written for both operators and maintenance personnel, and it begins with a clear statement that operators and maintenance staff must read it before operating or servicing the machine.

Within those chapters the manual works through the full scope of running a WA470-6: the front/rear, left/right orientation of the machine, visibility from the operator’s seat, the product identification number and engine serial number plate locations, service meter position, walk-around checks, checks before starting, starting the engine, checks after starting, moving and stopping the machine, steering, operation of the work equipment, digging and loading procedures, leveling, pushing, load-and-carry, parking, locking, transportation, lifting, towing, and emergency travel operation. The maintenance side is just as complete — it maps out the 50, 100, 250, 500, 1000, 2000, 4000, and 8000-hour service intervals, plus the initial 250-hour and initial 1000-hour services, with procedures for changing engine oil, replacing filter cartridges, cleaning strainers and breathers, checking and adjusting belts, checking brake discs and accumulators, cleaning radiator and cooler fins, replacing bucket teeth and cutting edges, and checking the air conditioner system.

The WA470-6 Operation & Maintenance Manual also includes the specification tables for the machine itself, covering overall dimensions, machine weight, normal load, bucket capacity, engine output, travel speeds, minimum turning radius, and permissible towing load. That means you can confirm the numbers before a job, during a repair, or when ordering parts without having to chase down a separate specification sheet.

What This Manual Supports

With this WA470-6 loader manual in hand, a technician can carry out routine maintenance correctly, diagnose warning and action codes on the machine monitor, understand the meaning of the central warning lamp and the individual caution lamps, and follow the safe procedures for operating in cold weather, on slopes, near high-voltage cables, in tunnels, and in dusty or asbestos-related environments. The troubleshooting chapter alone covers electrical system problems, chassis issues, transmission and axle faults, brake faults, steering faults, parking brake faults, hydraulic system faults, and engine problems, with the main causes and remedies listed for each.

The safety sections are not an afterthought — they are structured around the actual hazards of running this class of wheel loader. There are dedicated warnings for working under raised work equipment, handling high-pressure oil, dealing with high-temperature coolant and oil, using booster cables, handling the battery, working near the articulating portion, and preventing fires from fuel, oil, or electrical short circuits. Safety label locations are shown with the exact part numbers for replacement labels.

For buyers who need to maintain a WA470-6 without relying on a dealer for every task, this manual is the reference that makes the difference between guessing and knowing the correct procedure and specification.

Why It Matters

Komatsu designed the WA470-6 to handle heavy-duty loading, digging, and load-and-carry work. Operating and servicing it without the correct torque values, fluid capacities, adjustment clearances, or maintenance intervals is how machines get damaged, how components wear out early, and how safety incidents happen. The manual is written around the principle that most accidents are caused by failure to follow fundamental safety rules, and it applies that principle to every procedure it describes.

The maintenance schedule chart is particularly useful because it separates services into intervals that match real working conditions — 50 hours for draining water and sediment from the fuel tank, 100 hours for lubricating the rear axle pivot pin and checking the hydraulic oil level, 250 hours for checking the battery electrolyte level and alternator belt tension, 500 hours for changing engine oil and replacing the engine oil filter cartridge, 1000 hours for replacing the fuel main filter cartridge and changing transmission oil, 2000 hours for changing hydraulic oil and axle oil, 4000 hours for lubricating drive shafts and checking the water pump, and 8000 hours for replacing high-pressure piping clamps and the fuel spray prevention cap.
