. MAINTENANCE RECOMMENDED FUEL, COOLANT, AND LUBRICANT MAINTENANCE RECOMMENDED FUEL, COOLANT, AND LUBRICANT Note 1: Oil used in the power train is different from engine oil. Use an appropriate oil recommended for each application. Note .2: Axle oil AXO80 has the function of preventing squealing from the brakes and LSD (Limited Slip Differential). If only AXO80 is recommended, use Komatsu genuine AXO80 or equivalent. Note .3: When the ambient temperature is higher than 45 ° C (113 ° F) and the machine operation hour is longer than 12 hours/day, then the use of EO50-CD instead of AXO80 is recommended.
Squealing of the brakes may occur with EO50-CD, but there is no problem with the brake performance or durability. Note .4: If the machine is equipped with an automatic greasing system, see "HANDLING AUTO-GREASING SYSTEM (PAGE 6-31)". Note .5: 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 .6: Supercoolant (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 antifreeze coolant is essential.
Komatsu machines are supplied with Komatsu Supercoolant (AF-NAC). Komatsu Supercoolant (AF-NAC) has excellent anticorrosion,antifreeze and cooling propertiesand can be used continuously for 2 years or 4000 hours. Komatsu Supercoolant (AF-NAC) is strongly recommended wherever available. 2) For details of the ratio when diluting super coolant with water, see "CLEAN INSIDE OF COOLING SYSTEM (PAGE 4-21)". When the machine is shipped from the factory, it may be filled with coolant containing 30% or more Supercoolant (AF-NAC). In this case, no adjustment is needed for temperatures down to -10 ° C (14 ° F).
(never dilute with water) 3) To maintain the anticorrosion properties of Supercoolant (AF-NAC), always keep the density of Supercoolant between 30% and 68%.
