Specified capacity means the total amount of oil including the oil in the tank and the piping. Refill capacity
means the amount of oil needed to refill the system during inspection and maintenance.
Note 1: KDPF engine oil for cold areas deteriorates more compared with use in normal areas (replace every 500
hours). Therefore replace the oil and filter cartridge every 250 hours. For changing the maintenance time of ma-
chine monitor, ask your Komatsu distributor to perform the work.
Note 2: Power train oil has different properties from engine oil. Be sure to use the recommended oils.
Note 3: Hyper grease (G2-TE) has high performance.
When it is necessary to improve the lubricating performance of the grease in order to prevent squeaking of pins
and bushings, the use of 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 4000 hours.
Non-Amine Engine Coolant (AF-NAC) is strongly recommended wherever available.
2.
For details on the density of Non-Amine Engine Coolant (AF-NAC), see MAINTENANCE "METHOD FOR
CLEANING INSIDE OF COOLING SYSTEM".
Non-Amine Engine Coolant (AF-NAC) is supplied in diluted state, so always fill up with it. (Never dilute it
with water.)
Note 5: The DEF freezes at - 11 °C. If thawing is necessary, DEF system is automatically heated and thawed
after the engine is started.
