NOTICE
Always use diesel oil for the fuel.
To ensure good fuel consumption characteristics and exhaust gas characteristics, the engine mounted on this machine uses an
electronically controlled high-pressure fuel injection device. This device requires high precision parts and lubrication, so if low
viscosity fuel with low lubricating ability is used, the durability may drop markedly.
The ASTM diesel fuel recommended by Komatsu may contain 5% or less of biofuel. The EN diesel fuel may contain 7% or less of
it. Use the fuel which is filled into the storage tank or the fuel tank of the machine as soon as possible.
Note 1: HTHS ( High-Temperature High-Shear Viscosity 150°C (302°F)), specified by ASTM D4741 must be equal
to or higher than 3.5 mPa-S. Komatsu EOS0W30 and EOS5W40 are the most suitable oils.
Note 2: Powertrain 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: Coolant
1) Komatsu genuine SUPERCOOLANT (AF-NAC) 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 antifreeze coolant is essential.
Komatsu machines are supplied with SUPERCOOLANT (AF-NAC). SUPERCOOLANT (AF-NAC) has excellent
anticorrosion, antifreeze and cooling properties and can be used continuously for 2 years or 4,000 hours.
SUPERCOOLANT (AF-NAC) is strongly recommended wherever available.
2) For details of the density of coolant, see "CLEAN INSIDE OF COOLING SYSTEM (PAGE 4-22)".
Coolant is supplied already diluted. In this case, add the pre-diluted fluid to keep the tank full. (Never dilute coolant
with ordinary water.)
3) To maintain the anticorrosion properties of coolant, always keep the density of coolant between 30% and 64%.
