[. . . ] E mode ­ Economy or fuel priority mode further reduces fuel consumption, but maintains the P-mode-like working equipment speed for light duty work. Hydraulic control valve Flow divide/merge control with EPC Komatsu develops and produces all major components, such as engines, electronics and hydraulic components, in house. With this "Komatsu Technology, " and adding customer feedback, Komatsu is achieving great advancements in technology. To achieve both high levels of productivity and economical performance, Komatsu has developed the main components with a total control system. The result is a new generation of high performance and environment friendly excavators. Electronic control unit for engine Engine Heavy duty HPCR (High Pressure Common Rail) system Main pump Two pump independent control You can select Power or Economy modes using a one-touch operation on the monitor panel depending on workloads. Low Operation Noise Enables a low noise operation using the low-noise engine and methods to cut noise at source. Dynamic noise Low Fuel Consumption The newly-developed Komatsu SAA6D107E-1 [ecot3] engine enables NOx emissions to be significantly reduced with the accurate multi-staged fuel injection by the engine controller. [. . . ] Highly durable antislip plates maintain superior traction performance for the long term. Rear View Monitoring System (optional) The operator can view the rear of the machine with a color monitor screen. Low Vibration with Cab Damper Mounting PC270-8 uses viscous damper mounting for cab that incorporates longer stroke and the addition of a spring. The new cab damper mounting combined with high rigidity deck aids vibration reduction at operator seat. Anti-slip Plates Monitor for rear view camera Thermal and Fan Guards Thermal and fan guards are placed around hightemperature parts of the engine and fan drive. Rubber Spring Silicon Oil Pressurized Cab Optional air conditioner, air filter and a higher internal air pressure (+6. 0 mm Aq +0. 2"Aq) prevent external dust from entering the cab. Pump/engine Room Partition Pump/engine room partition prevents oil from spraying onto the engine if a hydraulic hose should burst. 6 7 PC270-8 H Y D R A U L I C E X C AVAT O R HYDRAULIC EXCAVATOR PC270-8 0 MAINTENANCE FEATURES Large LCD Color Monitor Large Multi-lingual LCD Monitor A large user-friendly color monitor enables safe, accurate and smooth work.
