USE OF FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE
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%.
Fuel sulphur content
0.5 to 1.0%
Above 1.0%
When starting the engine in an atmospheric temperature of lower than 0ûC, be sure to use engine oil of
SAE10W, SAE10W-30 and SAE15W-40, even though an atmospheric temperature goes up to 10ûC 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, 15W-40), but be sure to add
single grade oil that matches the temperature in the table.
We recommend Komatsu genuine oil which has been specifically formulated and approved for use in engine
and hydraulic work equipment applications.
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.
