This Komatsu D155AX-6 Operation and Maintenance Manual is the definitive reference for anyone responsible for operating, servicing, or maintaining this bulldozer. Spanning 373 pages, the document provides the complete factory guidance for the D155AX-6 with serial numbers 81077 and up. It opens with a thorough safety section that includes all warning labels and signal words used throughout the manual, then moves into component identification and the layout of controls and gauges. The operation chapter walks through every switch, lever, pedal, and monitor function with clear illustrations, followed by detailed procedures for daily checks, engine starting in normal and cold conditions, warming up, travelling, steering, and parking. The maintenance portion is extensive, offering a maintenance schedule chart that specifies service intervals and procedures for the engine, power train, final drives, hydraulic system, undercarriage, and air conditioner. It includes fluid capacities, torque values, wear limits, and step-by-step instructions for replacing filters, changing oils, checking track tension, adjusting idler clearance, and servicing the ripper and blade components. The troubleshooting section helps diagnose common electrical, chassis, and engine problems with probable causes and remedies. Technical specifications at the back list operating weights, dimensions, engine output, and travel speeds for the D155AX-6.

Whether you are a machine owner performing routine maintenance, a technician diagnosing a fault, or an operator wanting to understand the machine’s systems more deeply, this manual delivers the information you need in a single PDF. Every procedure is written for the D155AX-6 specifically, meaning the capacities, torque figures, and adjustment values are correct for this model rather than generic bulldozer data. The document covers the SAA6D140E-5 diesel engine as well as the hydraulic system, power train, steering, brakes, undercarriage, and all standard and optional work equipment including the various dozer blade configurations and ripper types.

Machine Systems Covered

The manual provides detailed coverage of the Komatsu SAA6D140E-5 diesel engine, including the fuel system, cooling system, lubrication system, and air intake and exhaust. The power train section addresses the torque converter, transmission, bevel gear, steering clutches, and final drives. Hydraulic system coverage includes the main control valve, hydraulic tank, filters, pumps, and cylinders for the blade and ripper circuits. The undercarriage chapter explains track tension adjustment, idler clearance, track shoe bolt tightening, and wear measurement for track rollers, sprockets, and idlers. Electrical content covers the battery, alternator, starting motor, fuse boxes, circuit breakers, and the machine monitor. The air conditioning system is also covered with instructions for checking refrigerant, replacing the belt, and cleaning or replacing the air filters.

What This Manual Enables You to Do

Having the correct Komatsu D155AX-6 Operation and Maintenance Manual means you can perform every scheduled maintenance task at the right interval with the right specifications. You can troubleshoot electrical faults using the wiring references, diagnose engine problems using the troubleshooting tables, and make correct adjustments to the undercarriage and work equipment. The manual tells you the exact tightening torques for critical fasteners, the correct fluid capacities for every reservoir, and the wear limits for cutting edges, ripper points, and track components. You will know how to safely start the engine in cold weather, how to warm up the hydraulic system before operation, and how to properly park and secure the machine on a slope. For anyone doing their own servicing, this manual effectively puts the factory’s service information on your computer or tablet, ready to print for the workshop.

Why This Manual Matters

Komatsu designed the D155AX-6 to deliver reliable performance in demanding dozing, ripping, and earthmoving applications. Keeping it running correctly depends on following the manufacturer’s procedures for inspection, lubrication, adjustment, and repair. Incorrect servicing can shorten component life, reduce performance, and create safety hazards. This manual provides the guidance that Komatsu intends for the people who operate and maintain the machine, ensuring that every task from a daily walk-around check to a major component replacement is performed correctly. The safety section alone is worth reviewing regularly, as it covers fire prevention, high-pressure oil hazards, battery handling, and the correct way to work around the machine when the engine is running.
