“Contents of the “Three-Level Maintenance System”. 1. Daily maintenance: Before and after each shift, operators should carefully inspect the equipment, wipe down all parts, and apply lubricating oil, so as to keep the equipment tidy, clean, lubricated, and safe at all times. And carefully keep inspection records and shift handover records. If a malfunction occurs in the equipment in the class, report it promptly, participate in troubleshooting, record the time and cause of the malfunction, and verify the effectiveness of the repairs. 　 2. Level 1 maintenance: Primarily carried out by operators under the guidance of maintenance workers; according to the plan, partial disassembly and inspection of equipment are performed, as well as cleaning of specified areas ； 　　Clear oil passages and pipes, replace or clean oil lines, oil felt, and filters ； 　　Adjust the clearance between various parts of the equipment and tighten all components of it. 　 3. Secondary maintenance: Focuses on repairs and is included in the equipment maintenance plan; involves partial disassembly, inspection, and repair of the equipment ； 　　Replace or repair worn parts, clean and change the oil ； 　　Inspect and repair the electrical components ； 　　Local recovery accuracy meets the minimum requirements for machined parts. 02 Content of “Three Goods” and “Four Skills”: The “three-level maintenance system” is implemented, and it is essential that operators meet the requirements of “Three Goods” and “Four Skills” when operating equipment: 1. Content of “Three Goods”: (1) Proper management: Consciously abide by the system of assigning specific persons to specific machines, use equipment only with an operation permit, and avoid using other people’s equipment indiscriminately ； Take good care of tools and accessories to prevent loss or damage, and keep them neatly arranged ； The safety protection devices are complete and functional ； Lines and pipelines are intact. 　　(2) Use properly: Ensure the equipment operates without defects, avoid overloading it, and do not use large-scale equipment for minor tasks or precision equipment for rough work ； Comply with operating procedures and maintenance regulations ； Take good care of the equipment to prevent accidents. 　　(3) Repair: According to the scheduled maintenance time ； Shut down for repair ； Actively cooperate with maintenance workers, and participate in the secondary maintenance of equipment, as well as major and medium-scale repairs and the final inspection and testing after completion. 　2. Content of the “four skills”: (1) Ability to use: Be familiar with the equipment’s structure, and understand its technical specifications and operating methods ； Understand the processing techniques and use the equipment correctly. 　　(2) Proper maintenance: Fill and change oil correctly according to the lubrication schedule, keep the oil passages unobstructed, and maintain cleanliness of oil lines, gaskets, and filters ； Clean thoroughly to keep the equipment clean both inside and outside, free from oil residues and dirt, so that the paint shows its true color and the metal is visible ； Perform level 1 maintenance work as specified. (3) Ability to conduct inspections: Understanding the accuracy standards of equipment, knowing the accuracy inspection items related to the manufacturing process, and being able to make appropriate adjustments ； The safety guards and insurance devices will be checked. (4) Fault elimination: It is able to detect abnormal conditions in the equipment through unusual sounds, temperatures, and operating patterns, determine the location and cause of these abnormalities, and take timely actions to eliminate the faults ； In the event of an accident, participate in the analysis to determine its causes, learn from the experience, and implement preventive measures.
