MIWA U9.LAMA, cylinder operation defect disassembly and cleaning

"The key is not working properly"

Although the information was quite vague, I decided to head to the scene anyway. Normal cylinder spray cleaning alone left a feeling of discomfort, so I disassembled it and cleaned the core. The problem was that there was a lot of dirt accumulated in the groove for the locking bar on the outer cylinder, so I removed it and completed the work.
