what he is talking of is, if you happen to have the box not perfectly centered when you tighten it, you can get it too tight and it as he stated, it will not want to return to center. when that happens you back it off a little 'til it is free.

although if it has 250k on it you probably wont be able to get it that tight.

just a little clarification, i hope
