FUEL HANDLING KOMATSU

FUEL


To prevent the moisture in the air from condensing and forming water inside the fuel tank, always fill the fuel tank after completing the day’s work.

The fuel pump is a precision instrument, and if fuel containing water or dirt is used, it cannot work properly. Be extremely careful not to let impurities get in when storing or adding fuel.

Always use fuel that matches the temperatures given in the Operation and Maintenance Manual.

If the fuel is used in temperatures lower than the specified temperature for use (particularly at temperatures of lower than -15°C), the properties of the fuel will make it congeal.

If the fuel is used in temperatures higher than the specified temperature for use, the viscosity will go down, and this may result in a drop in output or other problems.

Before starting the engine, or when 10 minutes have passed after adding fuel, drain the sediment and water from the fuel tank.

If the engine runs out of fuel, or if the filters have been replaced, it is necessary to bleed the air from the circuit.

If there is any foreign material in the fuel tank, wash the tank and fuel system. Excess fuel in the tank may spill out due to thermal expansion when the fuel temperature rises. Be careful not to fill with too much fuel.

NOTICE
Use only diesel fuel.
The engine mounted on this machine employs electronic control and a high-pressure fuel injection device to obtain good fuel consumption and good exhaust gas characteristics.  For this reason, it requires high precision for the parts and good lubrication.

If kerosene or other fuel with low lubricating ability is used, there will be a big drop in durability.
