Komatsu WB140-2N Operation & Maintenance Manual page 127

Remark
• When fuel sulphur content is less than 0.5%, change oil in the oil pan every periodic maintenance hours described in this
manual. Change oil according to the following table if fuel sulphur content is above 0.5%.
• When starting the engine in an atmospheric temperature of lower than 0°C (32°F), be sure to use engine oil of SAE1OW,
SAE2OW-20 and SAE10W-30, even though an atmospheric temperature goes up to 10°C (18°F) more or less in the day
time.
• Use API classification CD as engine oil and if API classification CC, reduce the engine oil change interval to half.
• There is no problem if single grade oil is mixed with multigrade oil (SAE10W-30, 10W-40), but be sure to add single
grade oil that matches the temperature in the table.
• Use Komatsu genuine oil which has been specifically formulated and approved for use in the engine, hydraulic work
equipment, transmission, axles, and brakes.
Specified capacity: Total amount of oil including oil for components and oil in piping.
Refill capacity: Amount of oil needed to refill system during normal inspection and maintenance.
