How can I use a chain link tool to repair my bike?

To use a chain link tool to repair your bike, first, place the tool on the chain link you want to remove. Then, turn the handle to push the pin out of the link. Once the pin is removed, you can separate the chain links. To reattach the chain, align the links and use the tool to push the pin back in place. Make sure the chain is properly connected before riding your bike.
