That is the main thing they warn of when you try to back out of a partial
cut. Have you rounded the back of the blade? That might help. I have a
cut blade guard too, from the back of the blade cutting in. Part of my
education.

been using my delta 14" saw for about 10 years. been using the same
blades
lenox bi metal blades forever too.
the first time it happed I was removing a piece of wood I cut only part
way.
sometimes the wood binds a bit and pulls the blade. but it does not cause
a
problem. but now the blade will jump forward and be about 1/2 on and 1/2
off the
wheel. at first I played around with the tracking to get it normal. but I
found
that if I just undo the tension and get the blade in the middle and
tighten it
it will move again the first time and stay the second usually. till
something
causes it to jump 1/2 off the wheel again.
it tracks fine till that sudden jump. then it will stay there untilled I
change
the tracking or undo and redo the tension.
the second time it happened it cut right through the blade guard sure
startled
me (G)
