Core Features & Technology

• Komatsu SAA6D107E-3 Engine: A 6.7L turbocharged engine delivering 196 hp. It uses a specialized Variable Geometry Turbocharger (KVGT) to provide optimum airflow across all load conditions, ensuring quick response and high torque even at low RPMs.

• Intelligent Machine Control (iMC 2.0): Available on the “LCi” models, this is a fully factory-integrated 3D system. Unlike “bolt-on” aftermarket kits, it uses stroke-sensing cylinders to automatically prevent over-excavation. It can semi-automatically follow a target surface—ideal for complex grading or trenching.

• Closed-Center Load Sensing (CLSS): Komatsu’s signature hydraulic system. It utilizes variable displacement pumps that provide “on-demand” flow, ensuring that multiple functions (swing, lift, and arm) move smoothly and simultaneously without one starving the other for power.

• Six Selectable Working Modes: Operators can toggle between P (Power), E (Economy), L (Lifting), B (Breaker), ATT/P (Attachment Power), and ATT/E (Attachment Economy). The system automatically adjusts engine speed and pump flow to maximize efficiency for each specific task.

• Auto-Idle Shutdown: To preserve resale value and fuel, the engine can be programmed to shut down automatically after a set period of idling (adjustable from 5 to 60 minutes), preventing “phantom” hours from accumulating on the machine.

Operator Comfort & Maintenance

• High-Resolution Widescreen Monitor: A 7-inch color LCD monitor serves as the “brain” of the cab. It provides a default view of the rearview camera alongside critical gauges like the DEF level, fuel consumption history, and active working mode.

• Enhanced Cab Mounting: The ROPS-certified cab is mounted on viscous isolation dampers. This design significantly reduces vibration and noise levels during high-impact work, such as rock ripping or using a hydraulic hammer.

• Ground-Level Serviceability: Komatsu centralized the engine oil filter, fuel pre-filter (with water separator), and the engine oil dipstick to one side of the machine. This allows the operator to perform the entire “daily walk-around” without climbing onto the upper structure.

• KOMTRAX Telematics: By 2022, KOMTRAX was highly advanced, providing owners with 4G LTE connectivity for remote monitoring. It tracks fuel theft alerts, AdBlue (DEF) levels, and provides “Eco-guidance” reports to help train operators on reducing fuel waste.

• iNDr-style Side-by-Side Cooling: The radiator and hydraulic oil cooler are mounted side-by-side rather than being stacked. This allows for easier cleaning and ensures that “hot air” from one core isn’t being pulled through another, improving the machine’s thermal efficiency in hot climates.
