I can't explain it, who can help me?

To generate hydraulic pressure without running the system, you will need to bypass the air solenoid valves within the hydraulic panel by supplying 5-6 bar (~80 psi) drive air directly to the hydraulic pumps and air-piloted hydraulic relief valves (both circuits). Apply 138 bar (2,000 psi) hydraulic pressure to both rolls / cylinders simultaneously and hold for 30 seconds.
What do you do (｡•ˇ‸ˇ•｡)? What does this mean?
I would like to ask the original poster, what part of this text is unclear to you and needs clarification? I don't see anything wrong?
I guess the poster didn't understand how to open the pneumatic valve/hydraulic relief valve.
The sentence is too long and cannot be read smoothly! In order to build up hydraulic pressure without activating the system, the air regulating valve in the hydraulic control panel needs to be bypassed to provide 5 to 6 kilograms of pressure to the hydraulic pump and air hydraulic relief valve. Provide 138 kg of pressure to the counter roller and hydraulic cylinder at the same time and maintain it for 30 seconds. Is there something wrong?

Apply 138 bar (2,000 psi) hydraulic pressure to both rolls / cylinders simultaneously and hold for 30 seconds. In order to build hydraulic pressure without starting the system, it is necessary to bypass the air regulating valve in the hydraulic control panel and provide 5 to 6 bar of driving air to both circuits of the hydraulic pump and the air hydraulic release valve. From this, add hydraulic pressure to the roller/cylinder at the same time to 138 bar and maintain it for 30 seconds.

Apply 138 bar (2,000 psi) hydraulic pressure to both rolls / cylinders simultaneously and hold for 30 seconds. If you do not want to operate the system to generate hydraulic pressure, you need to bypass the pneumatic solenoid valve in the hydraulic control panel by providing 5-6bar (approximately 80psi) driving air directly to the hydraulic pump and the pneumatic hydraulic relief valve (two circuits). Supply 138bar (2000psi) hydraulic pressure to two sets of rollers/cylinders at the same time for 30 seconds
