CONVENTIONAL PERFORMANCE IN A TIGHT TAIL BODY Rounded cab profile allows the cab to swing within the same swing radius as the counterweight for true tight tail performance. New engine and hydraulic pump control technology improves operational efficiency and lowers fuel consumption by up to 4%. A powerful Komatsu SAA6D107E-2 engine provides a net output of 116 kW / 158 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 proper 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. Komatsu's Closed Center Load Sensing (CLSS) hydraulic system provides quick response and smooth operation to maximize productivity. Enhanced working modes are designed to match engine speed, pump delivery, and system pressure to the application. Large LCD color monitor panel: ■ 7" high resolution screen ■ Provides "Eco-Guidance" for fuel efficient operation ■ Enhanced attachment control ■ Aux jack and (2) 12V outlets Rearview monitoring system (standard) Equipment Management Monitoring System (EMMS) continuously monitors machine operation and vital systems to identify machine issues and assist with troubleshooting. 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) Wide access service doors provide easy access for ground level maintenance. Guardrails (standard) provide convenient access to the upper structure. Battery disconnect switch allows a technician to disconnect the power supply before servicing the machine. Komatsu designed and manufactured components Side by side cooler design provides easy access to service and clean the cooler assembly. 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.
