If you perhaps look at the instructions the "safety" can be disengaged. I think the safety is more of a risk then not having it especially on a turret press. I defeated mine.
The chain is not used on a turret press and the instructions have been changed it seems. It originally came with the discontent in operation, it looks like now the user installs or activates it. Either way defeat it unless you want to remember to click it for every load which defeats the advantage of the turret press.
thanks for the replies. My instructions were different and were missing that whole piece about installing the safety. It was already installed on the powder measure. And now it's successfully removed.
