The fully automatic double-layer corrugated sheet machine requires regular replacement of hydraulic oil. During the replacement, ensure a thorough inspection and cleaning of the oil tank, oil lines, and other oil passages. Any foreign matter in the hydraulic oil can cause abnormality in the hydraulic system, increasing the operating time of components like the oil pump, cylinder, and directional valve. Therefore, we must always be attentive to the usage process of the machine.
