This manual gives you the full operational and maintenance picture for the WA200-6. It is not just a list of procedures — it explains the machine monitor warning system, how to interpret action codes and failure codes, how to perform everything from daily checks to 8000-hour service, and how to troubleshoot common problems across the engine, HST, axles, brakes, steering, and hydraulic system. The specifications section provides machine dimensions, weight, bucket capacity, travel speeds, engine output, and permissible towing load, while the maintenance schedule chart lays out every service interval from initial 10 hours through every 8000 hours.

Key Systems and Components Covered

The WA200-6 is a wheel loader built around the Komatsu SAA4D107E-1 diesel engine, producing 94 kW (128 HP) at 2000 rpm. The manual covers the HST (Hydrostatic Transmission) system, including the HST oil filter, HST drain filter, and HST oil temperature monitoring. It covers the transfer case, front and rear axles, service brakes, parking brake, steering system (including emergency steering), and the complete hydraulic system for the lift arm and bucket.

The electrical system coverage includes the machine monitor, all caution lamps and pilot lamps, the starting system, battery charging circuit, alternator, starting motor, preheating system, and the various switches that control traction, fan rotation, and work equipment. The manual also covers the air conditioner system, radio, and the KOMTRAX machine management system (for machines so equipped).

Safety content is extensive, covering safety labels and their locations, precautions for operation and maintenance, handling of high-temperature coolant and oil, high-pressure fuel and hydraulic oil, battery safety, accumulator handling, and tire safety. The manual also includes the location of the service meter, the table for entering serial numbers and distributor details, and a full index.
