It is necessary to change to the fuel that is suitable for the temperature.
To prevent the moisture in the air from c ondensing and forming water inside the fuel tank, always fill t he 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 fil ters have been replaced, it is necessary to bleed the air from the circuit. If there is any foreign material in the fu el tank, wash the tank and fuel system. Cooling System Coolant If the coolant level is low, it will cause ov erheating, and will also cause problems with corrosion due to air entering the coolant.
