Safety Information and Safety Labels

The opening safety sections explain the signal words and safety alert symbols used throughout the manual, then reproduce every safety label fitted to the D61EX-23M0 with its location on the machine and the full warning text. Labels covered include the operation and maintenance warning, the reverse travel warning, the leaving operator’s seat caution, high-temperature coolant and oil warnings, the accumulator warning, the track tension adjustment warning and the battery handling caution. The general precautions chapter then works through jobsite hazards, fire prevention, safe access to the machine, protective structures, towing and transportation rules, and the precautions that apply before starting inspection and maintenance.

Operation

This is the largest section of the Komatsu D61EX-23M0 manual and it covers the machine from the operator’s seat outward. It begins with the general view of the machine, the controls and gauges, and the machine monitor. Monitor coverage includes the standard screen, the check-before-starting screen, the maintenance warning screen, the action level monitor with its L01 to L04 levels, the alarm monitor list, the pilot display and the meter display. Every switch and lever is described with its function, including the starting switch, working mode selector, pedal mode selector, gear shift mode selector, joystick (steering, directional and gear shift lever), blade control lever, work equipment lock lever, parking brake lever and fuel control dial.

The operation section then walks through the daily checks before starting the engine, the starting procedure in normal and cold weather, the warm-up operation and the checks after starting. Machine operation is covered in detail: shifting gears, switching between forward and reverse, steering, counter-rotation turns, rules for operating on slopes, permissible water depth, travel on roads, and the recommended applications for dozing, leveling, cutting into hard or frozen ground and ditching, felling trees and removing stumps. The section closes with parking, checks after finishing work, lock points, long-term storage and troubleshooting procedures for towing, discharged batteries and other trouble.

Maintenance

The maintenance section lays out the rules for maintenance, the service meter reading and the maintenance schedule table. The schedule is broken into when-required items, checks before starting, and intervals at 50, 250, 500, 1000, 2000, 4000 and 8000 hours. Each procedure is written step by step with the tools, torque values and cautions needed. Covered procedures include cleaning and replacing the air cleaner element, cleaning the cooling system, checking and adjusting track tension, checking and tightening track shoe bolts, inverting and replacing the cutting edge and end bit, cleaning the radiator and oil cooler fins, lubricating the work equipment and equalizer bar, changing the engine oil and filter, replacing the fuel prefilter and main filter cartridges, changing the final drive oil, changing the hydraulic oil and filters, checking the accumulator nitrogen charge and checking the alternator drive belt. The section also includes procedures for bleeding air from the hydraulic circuit, adjusting center ball play and adjusting idler clearance.

Specifications

The specifications section gives the D61EX-23M0 machine weight (17,780 kg {39,198 lb}), engine model, rated horsepower, overall length, overall height, overall width and travel speeds in both quick shift and variable shift modes. The engine is identified as the Komatsu SAA6D107E-1 diesel engine, rated at 127 kW {170 HP} at 2,200 rpm gross and 125 kW {168 HP} at 2,200 rpm net. The lubrication chart and capacity table in the replacement parts section list the specified and refill capacities for the engine oil pan, hydraulic tank, final drive cases, fuel tank and cooling system.

Attachments and Options

This section covers the hydraulic ripper attachment for the D61EX, including its components, control lever operation, digging depth adjustment, point replacement and maintenance schedule. It also covers the general precautions for installing attachments and options, with warnings about stability, lifting and working under raised loads.
