! When fuel sulphur content is less than 0.5%, change oil in the oil pan according to every periodic main-
tenance hours described in this manual.
! Change oil according to the following table if fuel sulphur content is above 0.5%.
! When starting the engine with an atmospheric temperature of lower than 0°C (32°F), be sure to use
engine oil of SAE10W, SAE10W-30 and SAE15W-40, even though the atmospheric temperature goes up
to 10°C (50°F) more or less during the day.
! Use API classification CD as engine oil and if API classification CC, reduce the engine oil change inter-
val 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 range in the table.
! We recommend Komatsu genuine oil which has been specifically formulated and approved for use in
engine and hydrauric work equipment applications.
