Switching J-stik between 4/8 way

[dbldown768]

This might seem like a silly question but I have 2 jstiks from ultimarc and it seems to take some effort to switch between 8/4 way modes. There are 4 screws on the bottom that have some springs on them. All of them are pretty loose. Does it typically take a bit of effort to turn? Or am I doing something wrong.

You should be able to turn it with 1 hand using little effort.
