Features

A new boom and arm design increases the working range of the machine for more digging reach.

New engine and hydraulic pump control technology improves operational efficiency and lowers fuel consumption.

A powerful Komatsu SAA6D107E-2 engine provides a net output of 147 kW 196 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.

Large displacement high efficiency pumps provide higher flow output and efficient operation.

Enhanced working modes are designed to match engine speed, pump delivery, and system pressure to the application.

Komatsu Closed Center Load Sensing (CLSS) hydraulic system provides quick response amd smooth operation to maximize productivity.

Large LCD color monitor panel:
■ 7" high resolution screen
■ Provides "Eco-Guidance" for fuel efficient operation
■ Enhanced attachment control

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)

Komatsu designed and manufactured components

Guardrails (standard) located on the machine upper structure provide a convenient work area in front of the engine.

Swing out cooler design provides easy access to service and clean the cooler assembly.

Battery disconnect switch allows a technician to disconnect the power supply before servicing the machine.

Robust undercarriage design uses many of the same components that are used on larger machines.

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.
