This Komatsu WA470-6 Operation & Maintenance Manual goes far beyond a basic owner’s booklet. It is the reference document that Komatsu expects operators and service personnel to use for safe operation and correct maintenance of the WA470-6 wheel loader. The safety section alone covers everything from safety label locations and signal words to precautions for starting, traveling, operating, parking, towing, transportation, and maintenance. The operation section explains every switch, lever, pedal, and monitor display on the machine, including the machine monitor’s action code and failure code displays, the transmission shift modes, the kickdown and hold functions, the E.C.S.S. system, emergency steering, cooling fan reverse rotation, and the auto air conditioner controls. The maintenance section provides a full schedule chart from initial 250-hour service through every 8000-hour service, along with step-by-step procedures for each interval.

What This Manual Covers

The Komatsu WA470-6 is powered by the Komatsu SAA6D125E-5 diesel engine producing 203 kW (272 HP) at 2,000 rpm. This manual provides the complete service and maintenance information for that machine and engine combination. You will find procedures for changing engine oil and filter, replacing fuel pre-filter and main filter cartridges, servicing the transmission case and filter, changing hydraulic oil and filter elements, changing axle oil, checking brake disc wear, adjusting boom kickout and bucket positioner, checking and adjusting alternator belt tension, servicing the air conditioner, and much more.

Capacities are listed for every major system: engine oil pan (47 liters specified, 38 liters refill), transmission case (76 liters), hydraulic system (270 liters), front axle (60 liters), rear axle (56 liters), cooling system (61 liters), and fuel tank (413 liters). Recommended fuel, coolant, and lubricants are given according to ambient temperature, along with Komatsu genuine oil specifications and brand recommendations.

Standard tightening torques for metric bolts and nuts are provided in table form, as are hydraulic hose torque values. The manual also includes a torque list and a periodic replacement schedule for safety critical parts such as fuel hoses, steering hoses, brake hoses, transmission hoses, accumulators, and seat belts.

Detailed Service Procedures

The service procedure chapter walks through each maintenance task at the correct interval. Initial 250-hour service covers transmission oil filter cartridge replacement and hydraulic tank filter element replacement. Initial 1000-hour service covers engine valve clearance check and adjustment. When-required procedures include cleaning and replacing the air cleaner element, cleaning the cooling system, checking transmission oil level, checking axle oil level, cleaning axle case breathers, cleaning the air conditioner condenser, checking window washer fluid, cleaning radiator and cooler fins, turning or replacing bolt-on cutting edges, replacing bucket teeth, checking the air conditioner, replacing slow blow fuses, checking accumulator function, selecting and inspecting tires, and cleaning or replacing the fuel breather filter.

Every 50 hours: drain water and sediment from the fuel tank. Every 100 hours: lubricate rear axle pivot pins, check hydraulic tank oil level, clean the air conditioner fresh air filter element. Every 250 hours: check battery electrolyte, check parking brake, check alternator belt tension, check air conditioner compressor belt tension, check for loose wheel hub bolts, clean the air conditioner recirculation filter, check accumulator function, and lubricate.
