5. Work Content and Requirements

5.1 Establish Equipment Files

5.1.1 Establish files starting from equipment acceptance to equipment scrapping, implementing full-process control. Each equipment must have an independent file with a unified number for management. A specific equipment list should be established in the 'Equipment Ledger.'

5.1.2 Additional equipment attached to the equipment does not require separate files and relevant information is stored together with the main equipment.

5.1.3 Equipment-related information and documents are managed and preserved by the corresponding responsible departments. The information may include equipment user manuals, drawings, certificates of compliance, quality certificates, software CDs, etc., depending on the actual situation.

5.1.4 Equipment file contents include production equipment files, equipment acceptance reports, and equipment maintenance forms.

5.2 Equipment Identification

Classify and number all production equipment in the company for management purposes. The number format is:

Equipment number: Company code Department code Sequence number

5.3 Equipment Classification

5.3.1 Classify the equipment used based on its value, precision, substitutability, nature, and purpose, and divide the company's equipment into key equipment, important equipment, and general equipment.

5.3.2 Key equipment: A. High-value equipment; B. High-precision equipment; C. Equipment essential for production and unique within the factory.

5.3.3 Important equipment D: Equipment directly used for production that directly affects the product, including corresponding ancillary equipment.

5.3.4 General equipment E: Equipment that has little impact on production, such as forklifts and other handling equipment.

5.4 Establish Regular Maintenance Plans

5.4.1 Equipment management personnel collect data from the previous year, including key equipment and important equipment failure rates, unplanned downtime, equipment failure intervals, equipment maintenance records, replacement of spare parts, and annual maintenance and routine maintenance. They conduct comprehensive analysis, diagnose the operating status of key equipment and important equipment, and develop appropriate preventive, reactive, and predictive annual maintenance plans.

5.4.2 The annual maintenance plan includes daily maintenance plans, regular maintenance plans, preventive maintenance, and predictive maintenance plans.

5.4.3 Equipment personnel develop the regular maintenance plan, which needs to be implemented by relevant functional departments with clear division of labor and cooperation, and approved by senior company leadership when necessary.

5.5 Determine Key/Important Equipment Safety Stock

5.5.1 For key/important equipment, develop a detailed annual spare parts plan and fill out the 'Equipment Tooling Spare Parts Plan and Inventory' form, maintaining up-to-date contact information to ensure immediate availability of spare parts stored in the company.

5.5.2 Equipment personnel develop a spare parts plan based on actual production equipment needs, and purchase after approval.

5.5.3 The development of equipment spare parts should aim to reduce equipment failure rates.

5.5.4 Submit the next year's 'Equipment Tooling Spare Parts Plan and Inventory' at the end of each year. Determine the emergency retrieval method for key/important equipment spare parts based on equipment maintenance and maintenance conditions, actual equipment usage, equipment capacity, supplier delivery cycles, and the service life of the spare parts used.

5.5.5 The warehouse manager is responsible for the receiving, storage, and issuance of spare parts.

5.6 Equipment Usage

5.6.1 Before equipment is put into use, relevant technical personnel must provide systematic training to operators, who can only start working after passing the qualification assessment.

5.6.2 Operators must understand the operational requirements of the equipment.

5.6.3 Operators must strictly follow the operating instructions and/or safety operating procedures, and are not allowed to make unauthorized adjustments to the equipment.

5.6.4 Equipment with environmental requirements (such as temperature, humidity, light, etc.) must be strictly followed to ensure the technical performance of the equipment.

5.6.5 Learn to use emergency switches accurately and correctly.

5.6.6 Before operating the equipment, check and confirm according to the equipment checklist, and make records. Observe the dynamic conditions during operation and make handover records during shift changes.

5.6.7 If any abnormal phenomena occur during operation, stop the equipment immediately, submit a 'Production Equipment Maintenance and Maintenance Request Form,' and notify the corresponding responsible department for assessment and handling.

5.6.8 Pay attention to ensuring the safety of both the equipment and personnel. For non-routine operations and computer parameter adjustments, professional personnel should be consulted.

5.6.9 Record equipment operation for monitoring and improvement purposes.

5.7 Daily Maintenance of Equipment

5.7.1 Equipment maintenance is carried out jointly by equipment maintenance personnel and operators, implementing full-staff maintenance.

5.7.2 Full-staff equipment maintenance is an important means to keep equipment in good condition and ensure normal operation.

5.7.3 Equipment maintenance must be based on the '6S' management system, and operators should use production equipment according to the requirements of '6S.'
