Engine Oil Change:
Typically every 250-500 operating hours, depending on operating conditions and oil type. Consult manual for exact interval.
Engine Oil Filter Replacement:
Replace with engine oil change.
Fuel Filter Replacement:
Typically every 500 operating hours or as indicated by fuel system diagnostics.
Hydraulic Fluid Change:
Typically every 1000-2000 operating hours. Check manual for specific interval and fluid type.
Hydraulic Filter Replacement:
Replace with hydraulic fluid change.
Engine Oil Specification:
SAE 15W-40 API CJ-4 or equivalent. Consult manual for exact viscosity and specification.
