Caution about digging machine engine fuel, our many years of experience in second-hand excavator sales concluded the following: 1, in order to prevent condensation of moisture in the air to form water in the fuel tank, complete daily work, be sure To fill the tank full. 2, digging machine engine fuel injection pump is a precision parts, fuel moisture content or dirt, if used, the fuel pump will not work properly. 3, before starting the engine, used digging machine, or refuel after 10 minutes, to be discharged in the tank sediment and water. 4, if there are any impurities in the fuel tank to flush the fuel tank and fuel system. 5, if the engine has run out of fuel, or replace the filter, the oil must be drained of air. 6, (especially below -15 ° C (5 ° F) temperature) using the fuel in the fuel will be lower than the predetermined temperature solidification. 7, the fuel in use is higher than a predetermined temperature, the viscosity will decrease, output power decrease. 8, storage or refueling, should be particularly careful not to let qualified to enter. And oil passage. Diesel oil used for engineering machinery, such as CF-4 grade of oil, of which C represents the diesel engine oil; F representative of the quality grade, second-hand digging machine quality assurance, each increment of a letter, the oil will be better than previous performance species, more rearward letter, hand digging machine prices, higher quality grade; "- 4" riser grade engine oil performance, at the same level of oil, the higher the number, the better the quality. For imported models in the choice of oil is required in accordance with its engine fueling mode to choose: the choice of direct-injection turbocharged engine CF-4 grade oil can; EFI supercharged engine you need to use the CH-4 rating or higher grade oil to ensure the normal operation of the engine.
