Komatsu PC03-2-EC(S/N 15001-UP (FOR EC))

Use KOWA fluid analysis at 500-hour intervals to monitor engine and hydraulic wear. Check coolant SCA concentration at 500 hours to prevent scaling. Inspect hydraulic oil for water content and viscosity changes. Monitor engine oil for fuel dilution and soot levels. Track undercarriage wear measurements at 500 and 1000 hours. Analyze swing machinery oil for gear wear particles. Use Komatsu Supercoolant for extended life protection. Replace hydraulic return filters at 500 hours to maintain cleanliness.

Replace hydraulic hoses at 2000-hour intervals or upon inspection. Check final drive oil levels and change at 1000 hours. Inspect track tension and adjust if necessary. Replace worn track shoes and pads to prevent undercarriage damage. Check swing bearing for play and noise. Inspect boom and stick welds for cracks. Replace air filter elements when restriction indicator triggers. Check battery terminals for corrosion and tightness. Test all hydraulic functions for smooth operation.

Inspect final drives for oil leaks and gear wear at 2000 hours. Check swing circle for backlash and pitting. Inspect hydraulic pump for pressure loss and noise. Check engine compression and valve clearances. Inspect turbocharger for shaft play and oil leaks. Check undercarriage rollers and idlers for wear. Inspect boom and stick cylinders for seal leaks. Check structural components for fatigue cracks. Replace worn pins and bushings in linkage. Inspect electrical wiring for damage.

Check coolant freeze point before winter. Use lower viscosity engine oil in cold temperatures. Inspect heater and defroster operation. Check battery charge in cold weather. Clean radiator and oil cooler fins frequently in dusty environments. Check air filter restriction more often in dirty conditions. Inspect tracks for debris buildup. Check hydraulic hoses for cold-weather cracking. Use appropriate grease for temperature ranges. Check DEF level and quality in cold weather.
