To shear flat stock:
1. Set the controls for Punch and Inch, use the
foot actuator to raise the top shearing die and
make room for the workpiece, then turn the
motor OFF.
2. Brush one of the lubricants from Figure 18 on
Page 22 or an equivalent onto both sides of
the workpiece.
3. Loosen the lock knobs on the flat stock hold-
down (see
Figure 32), then rotate the shear-
ing hold-down adjustment rod to lift the hold-
down up enough to clear the workpiece.

5. Tighten the adjustment rod so that the hold-
down clamps the workpiece against the
shearing table, then re-tighten the lock knobs
(see Figure 33).
Note: Use the scored lines in the table to
align the workpiece.

4. Position the workpiece under the hold-down
and beyond the shearing dies (refer to
Figure
31 on Page 28).
6. Set the controls for Normal and Notch, start
the motor, then use the foot actuator to shear
the workpiece.
Note: Make sure the cut piece falls through
the rear exit panel and away from the dies so
that it does not interfere with the next opera-
tion.
Tooling and workpiece
could break apart under
pressure, sending metal
debris toward the opera
-
tor at a high rate of speed.
Always keep all safety
guards and access panels
in the correct position and
secured when perform-
ing cutting operations
to reduce the risk of this
hazard.
