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 maintenance time of machine monitor,
ask your Komatsu distributor to perform.
Note 2: Power train oil has different properties from engine oil. Be sure to use the recommended oils.
Note 3: When environment preservation is important in river works, marine and shore works, forest works, etc.,
recommend use of bio hydraulic oil and biogrease. If you use bio hydraulic oil, the fuel economy decreases a
little. When using it, consult your Komatsu distributor.
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: SUPERCOOLANT (AF-NAC)
1) Coolant has the important function of anticorrosion as well as antifreeze.
Even in the areas where freezing is not an issue, the use of 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 4000 hours.
SUPERCOOLANT (AF-NAC) is strongly recommended wherever available.
2) For the SUPERCOOLANT (AF-NAC) density, see “METHOD FOR CLEANING INSIDE OF COOLING SYS-
TEM (4-21)”.
SUPERCOOLANT AF-NAC is supplied in diluted state, so always fill up with diluted coolant. (Never dilute it with
water.)
Note 5: If this oil is used for hydraulic system, fuel consumption increases.
We strongly recommend HO56-HE for hydraulic oil.
If using alternative hydraulic oil (e.g. Panolin HLP Synth), the machine performance may be affected, especially
at high or low temperatures (e.g. low temperature starting, high temperature work equipment speed).
Note 6: DEF freezes at -11 °C. If thawing is necessary, DEF system is automatically heated and thawed after
the engine is started.
