Large Undercarriage Design significantly increases overside lift capacity and provides exceptional lateral stability in applications that require long arms or heavy attachments. New engine and hydraulic pump control technology improves operational efficiency and lowers fuel consumption. A powerful Komatsu SAA6D114E-5 engine provides a net output of 192 kW 257 HP. This engine is EPA Tier 4 Interim and EU stage 3B emissions certified. Komatsu Variable Geometry Turbocharger (KVGT) uses a hydraulic actuator to provide optimum air flow under all speed and load conditions. Komatsu Diesel Particulate Filter (KDPF) captures 90% of particulate matter and provides automatic regeneration that does not interfere with daily operation. Two boom mode settings provide power mode for maximum digging force or smooth mode for fine grading operations. Robust undercarriage is designed using larger size class components for increased reliability and component longevity. Large maximum drawbar pull provides excellent steering and slope climbing performance. Large LCD color monitor panel: ■ 7" high resolution screen ■ Provides "Eco-Guidance" for fuel efficient operation ■ Enhanced attachment control Rearview monitoring system (standard) Enhanced working modes are designed to match engine speed, pump delivery, and system pressure to the application. Enhanced working environment ■ High back, heated, and air suspension operator seat ■ Integrated ROPS cab design (ISO 12117-2) ■ Cab meets ISO Level 1 Operator Protective Guard (OPG) top guard (ISO 10262) Equipment Management Monitoring System (EMMS) continuously monitors machine operation and vital systems to identify machine issues and assist with troubleshooting. Komatsu's Closed Center Load Sensing (CLSS) hydraulic system provides quick response and smooth operation to maximize productivity. Heavy duty boom design with large one piece castings provides increased strength and reliability. Guardrails (standard) located on the machine upper structure provide a convenient work area in front of the engine. Battery disconnect switch allows a technician to disconnect the power supply before servicing the machine. Komatsu designed and manufactured components KOMTRAX^® equipped machines can send location, SMR and operation maps to a secure website utilizing wireless technology. Machines also relay error codes, cautions, maintenance items, fuel levels, and much more.
