. When repairing and replacing parts according to the above table, it must be determined that the pressure in the air compressor system has been released, separated from other pressure sources, the switch on the main circuit has been disconnected, and the safety sign that the switch is not allowed to be closed is completed. . B. The replacement time of the compressor cooling lubricant depends on the use environment, humidity, dust and air in the presence of acid and alkali gases. The newly purchased air compressor must be replaced with new oil for the first time of operation for 500 hours, and then replaced every 4,000 hours according to the normal oil change period. Machines with an annual operation of less than 4,000 hours should be replaced once a year. C. The oil filter must be replaced after the first start-up operation for 300-500 hours, the second time after 2000 hours of replacement, and then the normal time every 2000 hours. D. When repairing and replacing the air filter or intake valve, remember to prevent any debris from falling into the compressor mainframe. When the operation is completed, the main entrance is closed. After the operation is completed, it is necessary to manually rotate the main unit by a few turns in the direction of rotation to ensure that there is no obstruction before starting. E. Check the tightness of the belt every 2,000 hours of operation. If the belt is loose, adjust it until the belt is tight. To protect the belt, the belt should be prevented from being scrapped due to oil contamination. F. The oil filter must be replaced at the same time each time the oil is changed. G. Replace parts as much as possible with original company parts, otherwise the matching problem will occur and the supplier will not be responsible. To clean the cooler air compressor for about 2000h, in order to remove the dust on the heat dissipation surface, the cooler purge hole cover on the fan bracket should be opened, and the cooler should be purged with a blown air gun until the heat dissipation surface is cleaned. If the heat-dissipating surface is dirty and difficult to clean, remove the cooler, pour out the oil in the cooler and close the four inlets and outlets to prevent dirt from entering, then use compressed air to blow off the dust on both sides or use water. Rinse and finally blow dry water stains on the surface. Put it back in place. Remember! Do not scrape the dirt with a wire brush and other hard objects, so as not to damage the radiator surface is more detailed information on the maintenance of air compressors, if you maintain the price of an air compressor, manufacturer, model, pictures have any questions, please contact We get the latest information on the maintenance of air compressors.
