When adjusting the pressure of a waste paper baler, you can follow these steps:Check the type, shape, and thickness of the waste paper, as different types require different pressures.Ensure that the hydraulic system of the baler is functioning properly, with sufficient hydraulic oil, and that the correct type of hydraulic oil is being used.Turn on the power of the baler and check if the hydraulic oil level is correct.Based on the characteristics of the waste paper, choose an appropriate pressure level, which is usually achieved by adjusting the valves.Adjust the speed of the baler to suit the type and thickness of the waste paper.Adjust the position of the baler's cylinder to further adjust the pressure.

Use a pressure gauge to detect and adjust the pressure level, gradually increasing or decreasing the pressure until the desired level is reached during the adjustment process.If the pressure of the waste paper baler is insufficient, check the hydraulic system, oil seals, oil pipes, and connections to ensure there are no leaks or damage, and confirm that the oil pump and relief valve are working properly.
