♦ Fuel:
• Cetane number of 45 is minimum. Cetane number greater than 50 is preferred, especially for temperatures below
-20 °C (-4
°F) or elevations above 1500 m (5000 ft).
• Diesel fuels specified to EN 590 or ASTM D975 are recommended.
• N0.2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service. (SAE J313 JUN87)
^ Transmission Oil:
*KUBOTA Super UDT-2: For an enhanced ownership experience, we highly recommend Super UDT-2 to be used
instead of standard hydraulic/transmission fluid.
Super UDT-2 is a proprietary KUBOTA formulation that delivers superior performance and protection in all operating
conditions.
Regular UDT is also permitted for use in this machine.
