Hello I'm new here and I don't know if this is the right place to post this. I am trying to upgrade my Craftsman RAS 113.1971-50 with the new safety kit from Emerson. My problem is that the arm won't swing left past 48 deg but it will swing past 60 deg to the right. This is preventing me from correctly leveling the brackets for the new table-top. The auto stops are locking it in the 45,90, and 45 presets properly. I took the arm apart and didn't see any broken, loose or missing parts. Any help would be appreciated.
