REMARK
Specified
capacity means the total amount of fluid including the fluid in the tank and the piping. Refill capacity
means the amount of fluid needed to refill the system during inspection and maintenance.
Note 1: 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 2: 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.
The concentration of Non-Amine Engine Coolant (AF-NAC) is as shown in the following table.
