A. The pressure in the air compressor system has been released, it has been isolated from other pressure sources, the switch on the main circuit has been disconnected, and the safety sign that is not allowed to close has been prepared.
B. The replacement time of compressor cooling oil depends on the use environment, humidity, dust and whether there is acid or alkaline gas in the air. The newly purchased air compressor must be replaced with new oil after the first 500 hours of operation, and then every 4,000 hours according to the normal oil change cycle.
C. The oil filter must be replaced after 300-500 hours of operation for the first time, after 2000 hours of use for the second time, and every 2000 hours at normal time thereafter.
D. When repairing and replacing the air filter or intake valve, remember to prevent any debris from falling into the compressor main body cavity. When operating, close the entrance of the main unit. After the operation is completed, you need to rotate the main unit several times by hand in the direction of rotation to make sure that there is no obstruction before it can be turned on.
E. The tightness of the belt must be checked every 2000 hours of operation of the machine. If the belt is loose, it must be adjusted until the belt is tensioned; in order to protect the belt, it is necessary to prevent the belt from being scrapped due to oil pollution during the whole process.
F. Every time the oil is changed, the oil filter must be changed at the same time.
G. The replacement parts should use the original company parts as much as possible, otherwise the supplier will not be responsible for the matching problem.
