So I noticed my fence was not square while cutting a board. Problem is it's just on one side, and the body is one piece. I tried emailing Festool, I got a response but after sending pictures response stopped.
I am not speaking for Festool here. There are fence mounting bolts that if you loosen them on the "bad side" might release tension and allow it to come into plane. Once loosened it might also be able to force that side into position. My recollection is that has worked for some here.
My Makita miter saw was off like that.
Just loosened the securing bolts and there was enough play to allow it to be aligned perfectly straight again.
The designs look very similar.
Have this saw about 10 years. Pushing heavy stock against the fence caused the alignment issue and also a few kick backs when the blade snagged in bowed lumber.
