Standard additional counterweight provides equal or better lift capacity than most conventional excavators in the same size class. Rounded cab profile allows the cab to swing within the same swing radius as the counterweight for true tight tail performance. A powerful Komatsu SAA4D95LE-6 engine provides a net output of 68.8 kW / 93.5 HP. This engine is EPA Tier 4 Interim and EU stage 3B emissions certified. Variable Flow Turbocharger provides optimum air flow under all speed and load conditions. Komatsu Diesel Oxidation Catalyst (KDOC) reduces particulate matter using passive regeneration 100% of the time. No active or manual regeneration is required. 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 • 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. Komatsu designed and manufactured components New engine and hydraulic pump control technology improves operational efficiency and lowers fuel consumption by up to 7%. Guardrails (standard) provide convenient access to the upper structure. Battery disconnect switch allows a technician to disconnect the power supply before servicing the machine. 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.
