[. . . ] 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. Improved screen visibility is achieved by the use of TFT liquid crystal display that can easily be read at various angles and lighting conditions. Industry first function keys facilitate multi-function operations. Displays data in 12 languages to globally support operators around the world. 8 4 5 6 7 Side-by-side Cooling Since radiator, aftercooler and oil cooler are arranged in parallel, it is easy to clean, remove and install them. 1 2 3 Easy Access to Engine Oil Filter and Fuel Drain Valve Engine oil filter and fuel drain valve are remote mounted to improve accessibility. Sloping Track Frame Prevents dirt and sand from accumulating and allows easy mud removal. Radiator, aftercooler, and oil cooler made of aluminum have high cooling efficiency and are easily recycled. Gas Assisted Engine Hood Damper Cylinders The engine hood can be easily opened and closed with the assistance of the gas assisted engine hood damper cylinders. Equipped with the Eco-drain Valve as Standard. Prevents clothes and the ground from becoming contaminated due to oil 1 2 3 Long-life Oil, Filter Uses high-performance filtering materials and long-life oil.
