Utilize the KOWA program to monitor engine oil, hydraulic fluid, and coolant for wear metals and contaminants. Check coolant SCA concentration at 500-hour intervals to prevent scaling and corrosion. Monitor KOMTRAX data for load frequency and fault codes to anticipate powertrain stress. Analyze hydraulic oil particle counts to detect pump or valve wear early. Track DEF levels and quality to ensure SCR system efficiency. Use fluid analysis trends to schedule oil changes before critical degradation occurs, extending component life.

Address hydraulic hose leaks and cracks during daily inspections to prevent fluid loss and fire hazards. Replace worn brake pads and measure disc wear during 2000-hour comprehensive inspections. Check articulation and steering pins for excessive play, replacing them to maintain steering precision. Inspect and torque ROPS bolts to ensure cab safety integrity. Replace worn undercarriage components and measure wear to prevent premature failure. Check and adjust belt tension and inspect clamps to avoid power loss and overheating.

Plan engine overhauls based on KOWA analysis and cumulative hours, typically targeting major service intervals. Replace turbocharger components during 1000-hour inspections if wear is detected. Rebuild or replace final drives and differentials when oil changes reveal excessive metal content. Inspect swing machinery and replace worn bearings or gears during major service intervals. Evaluate the electric drive system components for insulation breakdown and wear. Plan structural inspections for boom and frame welds to identify fatigue cracks before they propagate.

Adjust coolant mixture and SCA levels for extreme temperatures to prevent freezing or boiling. Check DEF quality and storage to prevent crystallization in cold weather. Inspect rubber components like hoses and belts for hardening or cracking in high heat. Clean radiator and oil cooler fins frequently to prevent overheating in dusty environments. Check tire condition and inflation regularly to ensure stability on rough haul roads. Grease all suspension and steering points more frequently in wet or muddy conditions to prevent corrosion and binding.
