The saws specs are such that the splinter guard shouldn't be cut more when beveling, but I have experienced in the past a tiny amount being removed when cutting 45 degree miters. I've never done a thoeough investigation to see if it happens every single time -- I tend to do most bevel cuts on the table saw, and only really use the track saw for cross cut mitres on longer boards. Could be some error on my part factored in as far as balancing the saw correctly as well, but it has happened often enough that I've noticed it, and where the cuts otherwise come out perfectly (indicating I didn't lean the saw in such a way as to screw up the angle on the board).
Have other ppls experienced this?
