SHEAR OVERVIEW
The shear section has blades that can be reversed to provide a sharp edge as needed and are
capable of shearing up to 20 gauge (0.912
mm) mild steel sheet x 52” (1321mm) wide. An
adjustable upper blade assembly passes by a fixed lower blade resulting in a precise shearing
action. If necessary, the back gauge can be adjusted to accommodate repeat pieces.
Shearing Tips
Keep the blade gap to the smallest distance possible.
When shearing, the work should be squared against a guide.
The pressure plate should be adjusted approximately 0.125" (3.175mm) above the table
when the shear blade is in the up position. As the blade is moved downward, the pressure
plate should immediately rest against the workpiece and hold it in place.
To prevent distortion when shearing, snap the handle assembly quickly to pierce the
workpiece, then continue with steady even pressure to complete the cut.
After shearing, metal parts will have a sharp edge on them. These edges may cause cuts
when handled. Deburr the workpiece to remove the edge before handling.
Have the shear blades sharpened by a professional. This will lead to accurate, quality
results.
To avoid rolling over the edge of the sheet metal and pinching it between the two blades,
NEVER cut any piece narrower than eight times the thickness of the material.
