RECOMMENDED FUEL, COOLANT, AND LUBRICANT

RECOMMENDED FUEL, COOLANT, AND LUBRICANT
• Komatsu genuine oils are conditioned to maintain the reliability and durability of Komatsu construction
equipment and components.
• Commercially available lubricant additives may be good or bad for the machine. Komatsu does not recom-
mend any commercially available lubricant additive.
• Komatsu recommends using Komatsu genuine engine oil. If using engine oil other than Komatsu genuine
oil, it may reduce lubricant function. This causes shorter engine life, lowered engine performance and in-
creased fuel consumption.
• Use the fuel, oil, and lubricants to match the ambient temperature as recommended in the chart below.
• If the machine is operated at a temperature of –20 °C or lower, consult your Komatsu distributor.
Fuel
NOTICE
Always use ultra-low-sulfur diesel fuel.(≤10 ppm)
The ASTM diesel fuel recommended by Komatsu may con-
tain 5 % or less of biofuel. The EN diesel fuel may contain
7 % or less of it. Use the fuel which is filled into the storage
tank or the fuel tank of the machine as soon as possible.
Do not use any additive agent which includes metallic con-
stituent.
The metallic constituents in the additive agent may exces-
sively wear or damage the aftertreatment devices.

LUBRICATION CHART

• The lubrication chart uses symbols to show the lubrication points and types of lubricant by each lubrication
interval.
• Even if the same symbol is used in the lubrication chart, the recommended genuine oil may differ according
to the lubrication points and the ambient temperature. For details, see "METHOD FOR USING FUEL,
COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE".
• For details of lubrication, see "MAINTENANCE SCHEDULE TABLE".
