I have an old Rip-Cut which I bought many years ago but did not set. I seem to have lost the instructions, if I ever had them.
I cannot figure out which bolts are match with the nylon-lock screws.
This unit is old enough that the current instructions don't work. It doesn't have self tap screws for the guide - it has bolts/nuts. It has four other bolts - two for the base plate, two for elsewhere. Also, of the four nuts, two are nylon-lock, two are regular.
I found a link to a 2012 manual on this site, however it is no longer at kreg-tool.com.
