Regularly maintain the cleanliness of the cutting machine, clean the oil filter screen once a month, and set the hydraulic oil once a year. Before operation, pay attention to checking the oil level inside the machine. When the liquid level is below the specified level, add hydraulic oil of the same brand as the machine and do not mix them. When cutting materials, the workpiece should be placed in the center of the work area to ensure uniform force distribution throughout the cutting machine, thereby extending its service life.
