It details the correct procedures for starting the engine in normal and cold conditions, warming up the machine, shifting gears, steering, turning, and parking. For the technician, it provides torque values, wear limits, adjustment procedures, and service intervals for the engine, power train, hydraulic system, undercarriage, and work equipment.

Who This Manual Is For

This manual is intended for equipment owners, fleet managers, operators, and maintenance technicians working with the Komatsu D275AX-5E0 bulldozer. It is also a valuable reference for anyone needing to understand the machine’s specifications, capacities, and service requirements. The document assumes the reader has a basic understanding of heavy construction equipment and follows the safety instructions provided.

The D275AX-5E0 is powered by the Komatsu SAA6D140E-5 diesel engine rated at 335 kW (450 HP) at 2,000 rpm, and is available in Semi U-tiltdozer, U-tiltdozer, and Reinforced sigmadozer configurations. This manual covers all three configurations, with specific maintenance and adjustment procedures noted where they differ.

Why This Manual Matters

Proper maintenance and operation of a D275AX-5E0 bulldozer require accurate procedures and correct specifications. Using incorrect torque values, fluid types, or adjustment procedures can lead to premature component failure, reduced machine life, or unsafe operating conditions. This manual provides the correct values and procedures as specified by Komatsu for this machine, helping you avoid costly mistakes and downtime.

The maintenance schedule chart alone is worth the investment — it shows exactly what needs to be checked, cleaned, replaced, or adjusted at every service interval, from the initial 250-hour service through to the 8000-hour service. The wear parts list provides part numbers and replacement intervals for filters, cutting edges, end bits, ripper points, and other consumables, making it easier to plan maintenance and order the right parts.

Safety is a major focus of the manual. It includes detailed safety labels and pictograms, precautions for working on slopes, handling high-voltage cables, working in cold weather, and performing maintenance safely. The safety section is designed to prevent accidents and injuries by ensuring that operators and maintenance personnel understand the hazards associated with the machine and the correct procedures for avoiding them.
