Matters needing attention

Mahjong machine was first invented and produced in Japan. In the early 1990s, a small amount of original products were imported from Japan to China. Because of China's huge market, mahjong machine industry has entered a period of rapid development, forming a huge industrial chain. Mahjong machine has gradually successfully reformed from the No.30 small brand imported from China to the No.38, No.40, No.46 and even No.52 big brands.

The mahjong table should be kept clean. You can use a vacuum cleaner or brush to clean the dust and dirt on the table top and the suede of the central turntable in the machine, and scrub the licensing track and corner with care wax spray. Mahjong tiles should be kept clean and flat, and waxed and scrubbed after use. The moving parts in the machine, such as the slide bar of the card pusher and the slide bar of the flat pusher, should be flexible. Add a little grease (oil) when necessary, but don't add too much oil at will. Always clean the photoelectric switch with a small brush to avoid dust accumulation and affect the sensitivity of the photoelectric switch.
