1. First, put the chain on the front inner gear * and the rear gear. This is the time when the chain tension is the most loose, and then take out the bicycle chain that needs to be cut.

2. The tool for cutting short chains, the chain cutter, is taken out of the toolbox.

3. Then put the bicycle chain on the chain cutter, and aim the pin of the chain with the striker of the chain cutter. Be sure to aim, or the needle won't come out.

4. Then twist the chain knife hard. This means that the pin of the chain will slowly collide and take off the pin, so that the chain can be cut off.

Matters needing attention

1. Before moving the car backward and hanging the chain, change the chain to the state of minimum wheelset and minimum wheelset, so that the chain is loose, easy to operate and difficult to "bounce" after cutting.

2. After cleaning and oiling the chain, slowly reverse the toothed plate, and straighten the links pulled out from the back. If some links still keep a certain angle, it means that the movements are not smooth, they are fast knots and need to be adjusted. If a damaged link is found, it must be replaced in time. It is suggested that the three types of pins should be strictly distinguished and the chain should be maintained by connecting pins.

3. Pay attention to leveling when using the chain beater, so that the thimble is not easy to tilt. Careful use of tools can not only protect tools, but also achieve good results. Otherwise, tools are easy to be damaged, and damaged tools are more likely to damage parts, which is a vicious circle.
