3. INTRODUCTION 3.1 FEATURES 3.1.1 A HARD-WORKING MACHINE This machine mounts the highly evaluated SAA6D170E-2 engine with an output of 551.63 kW (740 HP)/2100 rpm for more powerful travel performance. The retarder performance when traveling downhill has been improved by using an exhaust brake in addition to the conventional wet-type multiple-disc retarder to give an improvement of 30% in the absorption torque. 3.1.2 The machine that anyone can drive and everyone wants to drive Every effort has been made to improve operator comfort and ease of operation, and the latest mechatronics controls are used to provide a smooth, powerful drive, excellent travel stability, and superb driving comfort.
All-range electronic modulation and auto suspension (auto suspension is optional for overseas specification machines), etc. A spacious, quiet, comfortable cab with composed coloring is used to reduce operator fatigue. 3.1.3 Trouble-free machine Even if any failure should occur, all the mechatronics systems are equipped with self-diagnostic functions. For example, the transmission control writes the failure codes to memory in the order that they occur, so troubleshooting is made much easier. 3.2 BREAKING IN THE MACHINE Your Komatsu machine has been thoroughly adjusted and tested before shipment.
