Fuel management 

Diesel should be selected according to different ambient temperatures; diesel should not be mixed with impurities, lime and water, otherwise the fuel pump will wear prematurely; the content of paraffin and sulfur in inferior fuel oil is high, which will damage the engine; the fuel tank should be filled with fuel after daily operation to prevent water droplets from forming on the inner wall of the fuel tank; open the water drain valve at the bottom of the fuel tank before daily operation; after the engine fuel is exhausted or the filter element is replaced, the air in the pipeline must be drained. Minimum ambient temperature 0 ℃ -10 ℃ -20 ℃ -30 ℃ Diesel grade 0 #-10 #-20 #-35 #.
