The BX25 Manual talks about those tabs for chaining up the 3ph.
I do not exactly remeber where I saw it but 2 weekends ago I was
reading and I remember seeing it. If I remember right it says the
tabs are for chaining up the 3ph so it will not fall...
This hookup is all good in my book. Learn sumthin' new every day!
You can take the side link and move it over to the holes where he ha it chained so the 3PH will not go up and down. It is mainly for the MMM. That is a good idea on chaining the rough cut like he has.
