Together these chapters take a technician through the complete lifecycle of the WA380-6: pre-start walk-around checks, warming-up procedures, work equipment control, correct load-and-carry technique, and the full Komatsu maintenance schedule keyed to service meter hours. The manual also documents safety-critical parts that must be replaced on interval regardless of appearance, standard torque tables, coolant and lubricant selection by ambient temperature, and factory capacity data for the engine oil pan, transmission case, hydraulic system, axles, cooling system and fuel tank.

Safety Information and Operating Procedures

The opening sections lay out Komatsu’s signal-word system (DANGER, WARNING, CAUTION, NOTICE, REMARKS), the position and meaning of every safety label on the machine, and the general precautions that apply to all operation and maintenance. Separate chapters cover working near high-voltage cables (with a voltage-to-safe-distance table), operating on loose ground and slopes, parking on a gradient, and emergency procedures such as releasing the parking brake, towing a disabled machine and starting with booster cables. The operation chapters walk through the machine monitor, switch panel, control levers, pedals and steering, then move through starting the engine (including cold-weather preheating), warming up, moving off, gear shifting, changing direction, and the specific procedures for digging piled soil or blasted rock, leveling, pushing and load-and-carry cycles.

Maintenance Schedule and Service Procedures

The maintenance portion is built around the Komatsu Maintenance Schedule Chart, with service procedures organised by interval: initial 10 hours (first 50 hours on a new machine), initial 250 hours, initial 1000 hours, then Every 50, 100, 250, 500, 1000, 2000, 4000 and 8000 hours, plus a When Required section. Procedures include changing engine oil and filter, replacing fuel pre-filter and main filter cartridges, servicing the water separator, cleaning the air cleaner element (outer and inner), changing transmission oil and filter, cleaning the strainer, changing hydraulic oil and filter element, replacing the hydraulic tank breather, changing axle oil, greasing, checking battery electrolyte, checking brake disc wear, and inspecting and adjusting the engine valve clearance. The manual also lists wear parts with part numbers and the recommended replacement interval, and identifies the safety-critical parts (fuel, steering, brake and transmission hoses, accumulator, seat belt, engine high-pressure piping clamp, fuel spray prevention cap) that must be replaced on a fixed time or hour interval.

Specifications and Attachments

The Specifications chapter gives the WA380-6’s overall length, height, width, bucket width, dumping clearance and reach, bucket dump angle, minimum turning radius, permissible towing load, travel speeds in all four forward and four reverse gears, machine weight, normal load, bucket capacity and flywheel horsepower for the standard specification machine. The Attachments and Options chapter covers selecting the right bucket and tires for the job, operating the torque converter lock-up, the joystick steering system, the multi-function lever with FNR switch, and machines equipped with KOMTRAX. Troubleshooting tables for the electrical system, chassis, transmission, axle, brake, steering, parking brake, hydraulic system and engine are included so that a technician can trace a symptom back to its likely cause and remedy.

Who This Manual Is For and How It Helps

Whether you are an owner-operator running a WA380-6 on a stockpile, a fleet maintenance planner building a service schedule, or a technician diagnosing a brake, transmission or hydraulic fault, this manual gives you the factory procedures and the numbers behind them. Using the correct torque, the right lubricant for the ambient temperature, and the specified service interval is what keeps the machine safe and productive — guessing leads to premature wear, downtime and, on safety-critical systems, real risk. Having the correct tightening torques, wear limits and troubleshooting tables on hand turns an unfamiliar job into a sequence of clear steps.
