Default Grizzly G4011 30" Sheet Metal Machine

/Hello, I just Picked up a Grizzly G4011 3in 1 Brake Shear Roll machine. When
I got it home, I tried to rotate the crank and the right "leading" side of the
cutter blade would bottom out against the right side frame. It is supposed to
clear to rotate completely to roll metal of different lengths. The cutter bar
bolts to each side arm so there is no adjustment to raise shear blade. The
side arms have an eccentric "cam" piece that gives the machine the stroke
action. The eccentric pieces on each side arm have brass bushing that could
wear out but these seam ok. They attach to the lower roller which drives the
rollers for the rolling process. The right side of the shear blade mounts
lower than the left so it will start the cut and work towards the left side of
the work piece. I cannot figure out why the right side of the blade bottoms
out against the support frame just enough to keep it from rotating. I remove
the shear blade and it rotates fine. I call Grizzly to see if they had 2
different blades sizes but he said not to his knowledge. The only thing I can
do is notch the side frame a little to let the blade clear as it comes down.
But I was wondering if anyone has experienced this . I ordered 2 new brass
bushings for the side arms but after inspecting of the existing ones, there is
no play. They do attach to the lower roller and the roller has bushings. There
is a little play which may be what's going on. I ordered new bushings for the
rollers as well. Any info or advice would be appreciated./
