Utilize the KOWA (Komatsu Oil Wear Analysis) program to monitor engine oil, hydraulic fluid, and coolant health. Regularly check for wear metals like iron or copper and contaminants such as silicon or sodium. Use KOMTRAX telematics to track fuel consumption, load frequency, and fault codes remotely. Periodic sampling of transmission and axle oils ensures early detection of component degradation before catastrophic failure occurs.

Monitor for power loss or restricted gear engagement, which often indicates transmission fluid contamination or low levels. Inspect the transmission damper if forward/reverse movement is interrupted. Watch for error codes like CA144 (high coolant temperature) or sensor voltage faults. Ensure fuel pumps are protected from water and dirt to prevent precision instrument failure. Check all steering hoses and priority valve connections if steering response becomes sluggish.

Plan for major component evaluations at the 2,000-hour interval. Critical rebuild focus areas include replacing worn articulation/steering pins and evaluating hydraulic pump/valve assemblies. Inspect turbocharger integrity and valve train clearances during 1,000-hour services. For high-hour machines, prepare for KDPF exchange units around 4,500 and 9,000 hours to maintain emissions compliance and engine performance.

In dusty environments, increase frequency of air filter inspections and radiator fin cleaning to prevent overheating. During cold operations, ensure the use of appropriate prediluted coolants (e.g., -40°C rated) to protect the engine block. Regularly check tire inflation and condition, especially when transitioning between hard surfaces and soft quarry ground. Ensure all grease points are serviced to prevent pin and bushing seizure in high-moisture conditions.
