REMARK
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 district is deteriorated easily than that for normal area (replace every 500
hours), so replace oil and filter cartridge every 250 hours. For changing the maintenance time of machine moni-
tor, ask your Komatsu distributor to perform the work.
Note 2: Hyper white 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 3: 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 recommends the use of Non-Amine Engine Coolant (AF-NAC). If you use another coolant, it may
cause serious problems in the cooling system, including the engine.
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 the density of Non-Amine Engine Coolant (AF-NAC), see “Coolant density table”.
Non-Amine Engine Coolant (AF-NAC) is supplied already diluted. In this case, fill up the tank with pre-dilu-
ted fluid. (Never dilute the Non-Amine Engine Coolant with ordinary water.)
