Recommended Brands And Qualities Other Than Komatsu Genuine Oils - Komatsu PC290LC-11 Operation & Maintenance Manual

RECOMMENDED FUEL, COOLANT, AND LUBRICANT REPLACEMENT PARTS
Note 3: When environment preservation is important in river works, marine and shore works, forest works, etc.,
recommend use of bio hydraulic oil and bio-grease. 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 (4-20)".
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.
Note 6: DEF freezes at -11 °C. If thawing is necessary, DEF system is automatically heated and thawed after
the engine is started.
