I checked my owner's manual and I did not see any comment with regard
to the range of swing on the saw. There was a note that adjusting the
saw to square affects both 45 degree postions. This makes me think
that one 45 degree stop is fixed and the other 45 is a detent just
like the 90 (or "square" ) stop. I think they allow full swing to the
right so you can cut miters greater than 45.
The guage on the top of the arm goes to 60+ on both sides, bt I also
have bevel guages on a bandsaw and a scroll saw that go beyond the
physical range of the tool.
So, I don't think it is an unusual occurance and I appreciate any
feedback offered. Thanks,
