The maintenance of assembly lines is not just about hardware, but also about the formal operation of staff. The flat design of the assembly line should ensure short transportation routes for parts, ease of operation for production workers, convenience for auxiliary service departments, effective use of production space, and consideration of the interconnection between assembly line installations. To meet these requirements, the form of the assembly line and the arrangement methods of the installation workstations should be considered during the flat layout of the assembly line.

1. Maintenance and care for the variable transformer of the motor's head: Absolutely no water should enter the motor; once it does, there's a chance of insulation damage, leading to the equipment failing to operate properly.

2. Chain Maintenance and Care: Chains require frequent observation and regular application of grease and lubricants. Due to the continuous operation of the chain, the lubricating fluid can evaporate over time, leading to increased noise and issues such as crawling.

3. Maintenance and care of the decelerator at the head of the production line: After using it for about a quarter, drain all the excess oil from the decelerator, then wash it with gasoline, diesel, and the like. Afterward, add new lubricant to the middle of the observation window. This procedure should be repeated every year. (Note: Insufficient lubricant can lead to increased noise and overheating of the decelerator, potentially causing it to fail. Also, the lubricant level should not exceed the middle of the observation window, as excessive levels can cause overheating and overloading of the motor, triggering the protective switch to disconnect.)
