Komatsu HB215LC-3, Operation & Maintenance Manual

Page: 478 / 492

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-sulphur 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.
When the diesel fuel is changed to the one mixed with the
bio-fuel, replace the fuel prefilter cartridge and the fuel
main filter cartridge with new ones.
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.
About Diesel Exhaust Fluid (DEF)
NOTICE
Use DEF as the aqueous urea solution for SCR system.
DEF is a colourless transparent 32.5 % aqueous urea solu-
tion.
The quality of DEF is prescribed in ISO 22241-1. Always
use DEF that conforms to this quality standard.
LUBRICATION CHART
• The lubrication chart uses symbols to show the lubrication points and types of lubricant by each lubrication
interval.
Keep this chart in the magazine box inside the cab so that the people concerned can refer it any time dur-
ing lubrication.
• 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.
