According to the cleanliness of diesel fuel, the diesel filter generally needs to be cured once every 5-10 days. Simply unscrew the screw plug to release the water or remove the water bottle of the pre-filter, pour the impurities and water, clean it and then install it.  The venting screw plug is installed on the diesel filter cover of the automobile crane to discharge the air in the diesel low-pressure pipeline and the diesel filter, and is also equipped with a return valve to ensure a certain pressure and excess in the oil passage. The diesel oil flows back to the mailbox through the return pipe. After the maintenance and cleaning of the diesel tank and the diesel pre-filter, it is usually necessary to use the manual pump of the fuel injection pump to deliver oil and exhaust in the low-pressure oil pipe. When venting, loosen the venting screw plug of the filter, and use the manual oil pump to pump oil continuously, so that the diesel oil containing the bubble will be discharged from the screw plug of the filter outlet until the bubble disappears, and the snail is tightened immediately. Plug, continue to pump oil, until the bubbles in the diesel oil discharged from the screw plug of the car crane filter are completely disappeared, and the diesel continues to swell. The filter cartridge needs to be replaced every six months or so. When installing, pay attention to the correct and reliable installation of the sealing ring on it, and replace it when it is damaged.
