1. Do not understand the common sense of maintenance to adjust the chain by yourself, but by mistake. This is a vague concept, only know that the chain adjustment is the category of maintenance, but don't know how to adjust it is the correct standard.
2. Because the chain of the chainring is severely worn, but the time or economy does not allow to replace it, or the matching machine cannot have a chainring of the same type at that time, the chain should be tightened and the machine will be forced to keep running.
3. When replacing the chain sprocket, the out-of-round eccentric sprocket was mistakenly installed on the machine, resulting in the chain being suddenly tight or loose. When checking and adjusting, one end is loose and the other end is too tight. No matter which of the above reasons cause the chain to be adjusted too tightly, it will greatly reduce the service life of the chain and the chainring. When the chain is adjusted too tightly, due to the increased contact pressure with the chainring, the chain is easily elongated, the link plate is easily deformed or broken, and the chain rollers will also be broken. In addition, the toothed disc will also become sharpened prematurely due to wear and tear, and in severe cases, it will become serrated.
