I have always used Wippermann chains and the tool less master link goes on and off quite readily. I just purchased my first KMC chain, and struggled to get the missing link to lock which it finally did. I then discovered that I had stupidly threaded the chain incorrectly. According to the instructions for removing the missing link, one is supposed to press the plates together of the link while pushing the links towards one another to open it. I have tried and tried, and I cannot seem to make the think even budge towards the opening position. Any ideas by those of you who use KMC chains with the missing link? Thanks.
