Hydraulic cylinders maintenance : 5,  before disassembling the hydraulic cylinders, the system should be unloaded, the circuit pressure should be zero, the oil source should be cut off, and the oil port should be blocked after loosening the oil port piping to ensure safety. 6, when the hydraulic cylinders leak and other faults need to be disassembled and repaired, the piston rod should be moved to the bottom of the cylinder first, and it is strictly forbidden to hit with hard objects during disassembly, so as to avoid the sudden drop of the piston rod and cause damage. 7, inactive or idle hydraulic cylinders for a long time should be turned on the operated regularly, so that all hydraulic cylinder components can be completely lubricated, so as to avoid rust on the working surface and affect the normal application in the future.
