WORKING ENVIRONMENT The cab interior is spacious and provides a comfortable working environment. . . Large Comfortable Cab Comfortable Cab New PC1250-8'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. Photo may include optional equipment. Thermal and fan guards are placed around high-temperature Seat with headrest reclined full flat Photo may include optional equipment. Low Vibration with Cab Damper Mounting PC1250-8 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. parts of the engine and fan drive. Anti-slip Plates Spiked plates on working surfaces provide anti-slip performance. 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 Anti-Slip Plates Rubber Spring productivity and comfort. Horn interconnected with Washable Cab Floormat The PC1250-8's cab floormat is easy to keep clean. The gently inclined surface has a flanged floormat and drainage holes to facilitate runoff. 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.

Easy Checking and Maintenance Wide center walkway provides easy access to many inspection and maintenance points. In addition, inspection and maintenance points are grouped to facilitate easy engine and hydraulic component checks. Air-operated greasing pump Fuel tank After cooler Oil cooler Radiator Hydraulic driven fan Control valve High-Quality EMMS Self-diagnostic System · Abnormality Checking Function If any abnormality should occur, the monitoring system checks whether hydraulic pressures, solenoid ON/OFF status, engine speed, electrical connections, etc. · Maintenance History Memory Function Maintenance records such as replacement of engine oil, hydraulic oil, filters, etc. · Trouble Data Memory Function Trouble data is stored to serve as references for future troubleshooting. Maintenance display of the EMMS multi-color monitor (Example) Maintenance time display Engine oil replacement display VHMS (Vehicle Health Monitoring System) (optional) VHMS controller monitors the health conditions of major components and enables remote analysis of the machine and its operation. This process is supported by the Komatsu distributors, factory and design team.
