01 SPECIFICATIONS
Note 1: HTHS (High Temperature High Shear Viscosity at 150 °C) must be 3.5cp or more. Optimum oils are
EOS0W30 and EOS5W40.
Note 2: Power train oil has different properties from engine oil. Be sure to use the recommended oils.
Note 3: Hyper grease (G2-T, G2-TE) has a high performance.
When it is necessary to improve the lubricating ability of the grease in order to prevent squeaking of pins and
bushings, the use of G2-T or G2-TE is recommended.
Note 4: Non-Amine Engine Coolant (AF-NAC)
1.
The coolant has the important function of preventing corrosion as well as preventing freezing.
Even in the areas where freezing is not an issue, the use of coolant is essential.
Komatsu machines are supplied with Non-Amine Engine Coolant (AF-NAC). Non-Amine Engine Coolant
(AF-NAC) has excellent anti-corrosion, antifreeze and cooling properties and can be used continuously for
2 years or 4,000 hours.
Non-Amine Engine Coolant (AF-NAC) is strongly recommended wherever available.
2.
For the concentration of Non-Amine Engine Coolant (AF-NAC), see the Coolant density table.
Non-Amine Engine Coolant (AF-NAC) is supplied in diluted state, so always fill up with it. (Never dilute it
with ordinary water.)
