Utilize KOWA fluid analysis at every 500-hour interval to monitor engine wear metals and hydraulic contamination. Check coolant SCA levels at 500 hours to prevent scaling. Monitor DEF levels daily to ensure Tier 4 compliance. Track fuel dilution and soot levels in engine oil to determine optimal change intervals based on actual operating conditions rather than fixed schedules.

Address hydraulic return filter clogging promptly to prevent pump damage. Inspect wet disc brakes for wear and measure pad thickness at 500-hour intervals. Check final drive oil for metal particles indicating gear wear. Replace air filter outer elements when the restriction indicator signals. Inspect suspension cylinders for seal leaks and rod scoring common in coal dust environments.

Plan engine overhaul based on KOWA trends and hours, typically around 20,000 hours. Replace turbocharger components during major service intervals. Inspect transmission and inverter systems for wear. Check structural welds on the dump body and chassis at 1000-hour intervals. Replace all belts and hoses at 2000 hours to prevent sudden failures.

In dusty Antelope Coal conditions, check air filters more frequently than standard intervals. Drain water from the fuel separator daily to prevent injector issues. Use Komatsu Super Coolant AF-NAC to manage heat in high-load scenarios. Inspect undercarriage and tires for damage from sharp coal debris. Ensure cab filtration is clean to protect operators from particulate matter.
