Apron Angle to Bed Alignment
The top of the Apron Head / Angle must be parallel and level with the Bed Table.
To raise or lower each Apron end:
· Loosen the jack bolt jam nut(s)
· Loosen Apron to Bracket bolts
· Turn the jack bolt to raise or lower
When apron to bed is parallel & level:
· Tighten the jack bolt jam nut(s)
· Tighten Apron to Bracket bolts
Test the adjustments, use test strips of metal, each approximately 3 inches by 3 inches, of the thickness
being formed.
Over-bending -- Check end-to-end alignment by clamping two test strips in the brake, about 3 or 4 inches
away from either end of the brake. Bend to about 90 degrees, and see if they appear to be bent to the
same degree. Remove them from the brake and stack one inside the other. Compare the sharpness of
the radius. If one test strip is over-bent or has a sharper radius, slightly move the end of the clamp head
which that strip came from. The clamp assembly should be moved back on the end where the over-
bending occurs by slightly unclamping the clamp handle, loosening the bracket lock screw and turning the
adjusting bracket screw. When the correction is made, retighten the bracket lock screw.
