5 Maintenance Fuel The fuel pump is a precision instrument; if fuel containing water or dirt is used, it cannot work properly. Be extremely careful not to let impurities penetrate when storing or adding fuel. Always use the fuel specified in the Operation and Maintenance Manual. Fuel may congeal depending on the temperature (particularly at low temperatures below -15°C), so change to a fue matching this temperature. 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. 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, you must fill up the fuel pre-filter with fuel and may then restart the engine. For details, see "Bleeding the fuel system" on page 5-55. If the fuel sulphur content is between 0.5 and 1.0%, the oil change interval must be 1/2 normal. If the fuel sulphur content is more 1.0%, the oil change inter val must be 1/4 normal. 5-14 WA90-5 – VEAM270100
