In order to remove.
General should put off the oil cylinder two cavity, and then remove the cylinder head, after remove the piston and piston rod.
This is because all sorts of laser cylinder structure and size is not the same, disassembly sequence is also slightly different.
4.
To ensure that the discharge pressure is carried out in a clean environment.
