FUEL, COOLANT AND LUBRICANTS

NOTICE
Always use diesel oil as fuel.
To ensure good characteristics of fuel consumption and exhaust gases, the engine fitted to this machine
uses an injection device at high pressure.
This device needs that components and lubrication have high precision characteristics, therefore, its
working life may be considerably reduced if you use low viscosity fuel with poor lubricating capacity.
Note 1:
transmission oil has properties different from those of engine oil. Make sure to use the recommended oil.
Note 2:
The super white grease (G2-T, G2-TE) has high performance.
If it is necessary to increase the grease lubricating capacity to prevent pins or bushes squeaking, use
recommended G2-T or G2-TE.
Note 3:
Supercoolant (AF-NAC)
1. The coolant carries out the important function to prevent corrosion as well as freezing.
In the areas where freezing is not a problem, it is essential to use of an antifreeze coolant.
All Komatsu equipment are supplied with Komatsu Supercoolant coolant (AF-NAC). Komatsu Supercoolant
coolant (AF-NAC) has excellent anticorrosive, anti-freezing and cooling properties and may be used
constantly for 2 years or 2000 hours.
It is advisable to use Komatsu Supercoolant coolant (AF-NAC) at all times.
2. For information on dilution ratio of the Supercoolant in water, see "CLEANING OF THE COOLING SYSTEM
AND CHANGING THE COOLANT (4-66)".
3. To keep the anticorrosive properties of the Supercoolant (AF-NAC), always keep its density between 30% and
68%.
Note 4:
Use only low- or ultra low-sulphur content fuel.
