• Attachments and Options – selecting bucket and tires, auto-greasing system, service centre, emergency engine stop switch, battery and starting motor disconnector switches, starting aid connector, centralised breather, hydraulic oil level warning display
• Index

Within these sections the Komatsu WA800-3E0 WA900-3E0 manual covers the engine, transmission, torque converter, axles and final drives, brakes and accumulators, steering system, hydraulic tank and filters, electrical system with fuse and circuit-breaker layouts, the auto-greasing system, air conditioner service, cold-weather precautions, and towing and lifting procedures. Each service item carries the torque figure, oil capacity, or clearance value needed to finish the job correctly.

Safety Information That Applies Every Shift

The safety chapter of this Komatsu WA800-3E0 WA900-3E0 wheel loader manual is not a formality – it prints the exact safety label set that should be on the machine, then explains the reasoning behind each one. You get the voltage-distance table for working near high-voltage cables, frame lock bar precautions for transportation and maintenance, ROPS/FOPS handling rules, the accumulator and gas-spring warnings, and the high-pressure oil and fuel precautions that protect a technician from injection injuries.

Daily, Periodic, and Long-Interval Service

The maintenance schedule chart in the Komatsu WA800-3E0 WA900-3E0 Operation and Maintenance Manual breaks the service life of the machine into clear intervals: initial 10 hours, initial 250 hours, then every 50, 100, 250, 500, 1000, 2000, 4000 and 8000 hours. Each interval lists the exact job – draining water from the fuel pre-filter, checking the parking brake, adjusting the alternator belt, replacing transmission oil filter elements, cleaning the hydraulic tank strainer, changing axle oil, checking brake disc wear, replacing high-pressure piping clamps – and points to the page where the procedure lives. Because the schedule is tied to the service meter, it removes the guesswork about whether a machine has actually been serviced on time.

Monitors, Fault Codes, and Diagnostics

The operation section explains the main monitor and maintenance monitor in detail, including every warning lamp, pilot lamp, gauge, and the character display on the engine service monitor. Action codes E00, E01, E02, E03 are described with the required response for each, and the manual shows how to step through to the underlying failure code and identify which controller detected it. This is the part of the Komatsu WA800-3E0 WA900-3E0 manual a technician reaches for when the machine starts throwing alarms mid-shift.

Troubleshooting Without Guesswork

The Komatsu WA800-3E0 WA900-3E0 wheel loader manual’s troubleshooting chapter lists real symptoms – the engine will not start, the machine will not move, the transmission oil overheats, the brakes drag, the steering is heavy, the bucket lacks lifting power, exhaust is white or blue – alongside the likely causes and the corrective action. There is also the emergency procedures block covering a discharged battery, booster cable connection order, prelube skip function, lowering the work equipment after the engine has stopped, and towing a disabled machine.

Specifications and Wear Data

Specifications for both the WA800-3E0 and WA900-3E0 are printed together so the differences are easy to compare: operating weights, overall length, height, width, bucket width, dump angle, turning radius, and travel speeds. The wear parts list is equally practical – it names every filter cartridge, element, and tooth with its part number and replacement interval, which saves a phone call when you are reordering for a service truck.

What This Manual Lets You Do

With the Komatsu WA800-3E0 WA900-3E0 Wheel Loader Operation and Maintenance Manual on hand, an owner or fleet technician can carry out the full daily check routine, run the machine correctly through the warm-up and break-in phases, complete every scheduled service interval, diagnose monitor faults, bleed the fuel, brake, hydraulic, and PPC circuits, adjust the bucket positioner and remote positioner, set the transmission cut-off, and handle cold-weather and long-term storage preparation. Correct torque values, fluid capacities, tire pressures, and safety procedures are all in one document – which is exactly what protects the machine from premature wear and protects the operator from the hazards these large loaders present.
