[. . . ] · Electronically controlled variable speed fan drive · Large hybrid fan · Glasswool-furnished low-noise muffler and noise reducing cover around the muffler See page 4. Easy Maintenance Easy Cleaning of Cooling Unit Fan reverse-rotation function facilitates clogged radiator cleaning. Centralized Arrangement of Engine Checkpoints Anti-slip Plates for improved foot traction Large Handrail, Step and Catwalk provide easy access to the engine and hydraulic equipment. Increased Fuel Tank Capacity See page 10. Excellent Reliability and Durability KMAX Bucket Teeth offer superior penetration and longterm sharpness. O-ring Face Seals, which have excellent sealing performance, are used for the hydraulic hoses. [. . . ] When maximum digging force is needed, switch to power mode for more effective excavating. Boom raise Smooth mode Power mode Environment-friendly Clean Engine Mounted Komatsu SAA6D140E-5 engine is Tier 3 and EU stage 3A emissions certified. The SAA6D140E-5 engine adopts the world's first cooled EGR system with electronically controlled bypass-assist type venturi. NOx emission is reduced 40%, while maintaining high power and low fuel consumption. Shockless Boom Control The PC800-8 boom circuit features a shockless valve (double-check slow return valve) to automatically reduces the amount of vibration present when operating the boom. Operator fatigue is reduced (which can improve safety and productivity), and spillage caused by vibration is minimized. Lower and Economical Fuel Consumption Using Economy Mode Enables operator to set the Eco mode to up to four levels according to working conditions so that production requirement is achieved at lowest possible fuel consumption. Power Mode Economy Mode Heavy Lift Mode Extend and retract Swing Priority Mode Reduction of Ambient Noise (optional) This is an image photo: may differ from the actual engine. 4 Reduced noise by adoption of an electronically controlled variable speed fan drive, large hybrid fan, low-noise muffler and cover with glasswool, to meet EU stage 2 noise regulations. 5 PC800-8 H Y D R A U L I C E X C AVAT O R HYDRAULIC EXCAVATOR PC800-80 RELIABILITY FEATURES Excellent Reliability and Durability Boom Foot Hoses The boom foot hoses are arranged under the boom foot to reduce hose bend during operation, extending hose life and improving operator safety. Strengthened Quarry Bucket Provides Outstanding Wear-resistance (optional for PC800SE-8) The bucket for specific use in quarry is impact and wear resistant, providing high performance and long life. Combined with adoption of long-life KMAX teeth, durability of bucket is drastically enhanced. Quarry Bucket with KMAX Tooth * Koma-hard materials (KVX materials): Komatsu developed, wear-resistant, reinforced materials. Repeat steps 1-3 for a new installation. 6 7 PC800-8 H Y D R A U L I C E X C AVAT O R HYDRAULIC EXCAVATOR PC800-80 Safety Features Step light with timer provides light for about one minute to allow the operator to get off the machine safely. WORKING ENVIRONMENT The cab interior is spacious and provides a comfortable working environment. . . Large Comfortable Cab Comfortable Cab New PC800-8's cab offers an exceptionally comfortable operating environment. The large cab enables full flat reclining of the seat back with headrest. Pump/engine room partition prevents oil from spraying on the engine if a hydraulic hose should burst. Pressurized Cab The optional air conditioner, air filter and a higher internal air pressure (6. 0 mm Aq 0. 2" in Aq) prevent external dust from entering the cab. Low Noise Design Noise level is remarkably reduced, not only engine noise but also swing and hydraulic relief noise. Seat with headrest reclined full flat Photo may include optional equipment. placed around high-temperature parts of the engine and fan drive. Anti-slip Plates Spiked plates on working surfaces provide anti-slip performance. Low Vibration with Cab Damper Mounting PC800-8 uses a new, improved cab damper mount system that incorporates longer stroke and the addition of a spring. The new cab damper mounting combined with a strengthened left and right side deck, aids vibration reduction at the operator's seat. Vibration at floor is reduced from 120 dB (VL) to 115 dB (VL). dB (VL) is index for expressing size of vibration. Automatic Air Conditioner (optional) A 6, 900 kcal air conditioner is utilized. 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. Multi-position Controls The multi-position, PPC (proportional pressure control) levers allow the operator to work in comfort while maintaining precise control. A double-slide mechanism allows the seat and control levers to move together or independently, allowing the operator to position the controls for maximum productivity and comfort. Rubber Spring Anti-Slip Plates Horn interconnected with Seat Sliding Amount: 340 mm 13. 4", increased 120 mm 4. 7" warning light (optional) give visual and audible notice of the excavator's operation when activated. Silicon Oil Comparison of Riding Comfort Cab Damper Mounting Multi-Layer Viscous Mount Vertical direction on graph shows size of vibration.

The gently inclined surface has a flanged floormat and drainage holes to facilitate runoff. Defroster (optional) Cab Frame Mounted Wiper Bottle Holder and Magazine Rack Floor Vibration 8 9 PC800-8 H Y D R A U L I C E X C AVAT O R HYDRAULIC EXCAVATOR PC800-80 EASY MAINTENANCE FEATURES Komatsu Designed the PC800-8 for Easy Service Access. Easy Checking and Maintenance of Engine Engine check points are concentrated on one side of the engine to facilitate daily checks. Thermal guards are placed around high-temperature parts such as turbocharger. High-Quality EMMS Self-diagnostic System Steps Connected to the Machine Cab Steps allows access from left hand catwalk to top of machine for engine check and maintenance. · Abnormality Checking Function In case any abnormality should occur, the monitoring system checks whether hydraulic pressure, solenoid ON/OFF status, engine speed, electrical connections, etc. are in the normal conditions to keep the machine downtime to a minimum.
