Fuel, coolant and lubricants
MAINTENANCE
Proper selection of fuel, coolant and lubricants
4-10
*1 :ASTM D975 No.1
*2 : Use only diesel fuel.
*3: For the standard differential, except for “AXO80“, the oil for machines equipped with the limited-slip differential
in the table below and E030 can be used. However, in the case of “E030“, depending on conditions such as the
way the brakes are used and the oil temperature, the brakes may squeal just before the machine stops, but
there is no problem with the brake performance or durability.
*4: The letters “ASD“ are stamped on the name plate of machines equipped with the limited-slip differential axle.
*5: For machines equipped with the limited-slip differential axle, select from the oil given in the table below.
Never use any oil except the oil listed in the table below.
REMARK
When fuel sulphur content is less than 0.5%, change oil in the oil pan according to the periodic mainte-
nance 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 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.
