[. . . ] Strengthened Revolving Frame with Deck Guard Quarry Cab Large Digging Force Pressing the Power Max function button temporarily increases the digging force 7%. Two-mode Setting for Boom Switch selection allows either powerful digging or smooth boom operation. See page 5. Large TFT LCD Monitor · Easy-to-see and use 7" large multi-function color monitor · Can be displayed in 12 languages for global support. TFT : Thin Film Transistor LCD : Liquid Crystal Display Quarry Bucket Full Roller Guards and Double-flange Track Rollers See page 8. Safety Design · Cab dedicated to hydraulic excavator for protecting the operator if the event of machine rolls over. · Anti-slip plates for safe work on machine · Rear view monitoring system for easy checking behind the machine (optional) See page 7. 2 Photo may include optional equipment. Excellent Reliability and Durability · The fuel reliability is improved by adding fuel main-filter and water separator working against low grade fuel. · Equipped with fuel pre-filter as standard (with water separator). [. . . ] You can set the appropriate operational posture of armrest together with the console. Reclining the seat further enables you to place it into the fully flat state with the headrest attached. Automatic Air Conditioner (optional) Enables you to easily and precisely set cab atmosphere with the instruments on the large LCD. The bi-level control function keeps the operator's head and feet cool and warm respectively. This improved air flow function keeps the inside of the cab comfortable throughout the year. Defroster function keeps front glass clear. Thermal and Fan Guards Thermal and fan guards are placed around hightemperature parts of the engine and fan drive. Low Vibration with Cab Damper Mounting PC450-8R 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 Highly durable anti-slip plates maintain superior traction performance for the long term. Large Serrated Steps Large Handrail Rubber Spring Pressurized Cab Silicon Oil Optional air conditioner, air filter and a higher internal air pressure (+9. 0 mm Aq +0. 35"Aq) prevent external dust from entering the cab. 6 7 PC450-8R H Y D R A U L I C E X C AVAT O R HYDRAULIC EXCAVATOR PC450-8R 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. Function keys facilitate multi-function operations.
