SECTION 3 : OPERATIONS
For precision shearing from 2'' to 10'' lengthwise,
first attach the back measurement assembly to
the receiver holes in the back of the crossbeam:
1. To adjust the position of the back measure-
ment assembly, first loosen the two knobs.
2. Move the assembly forward and back using
the handwheel. When the assembly is at the
desired position, tighten the knobs to lock it
into position.
3. If a precise 90˚ angle is desired, attach the
guide to the left side of the cutting table using
the two Allen
® screws.
4. Using the handle assembly, raise the upper
cutting die to the highest position. Slide the
workpiece in between the braking die and the
work surface.
5. Rotate the handle assembly to shear the
workpiece at the desired location.
During shearing operations, there are two condi-
tions which may cause uneven cuts:
1. Shear Bow. There is a tensioning adjustment
on the shear plate which can create a bow
necessary to cut certain materials. Adjust the
tension on the bolt attached to the shear
frame adjustment bar. Tightening the bolt will
cause the ends of the shear to bow out, loos-
ening the bolt will cause them bow in.
Shearing
The handle is shipped mounted to the right side of
the machine. If left hand operation is required, the
handle can be moved to the opposite side of the
machine:
1. Remove one of the handles.
2. Loosen the handle adjustment knob and
slide the handle arm out of the slot.
3. Slide the handle arm into the opposite side
and tighten the handle adjustment knob.
4. Reattach the handle.
5. The handle arm can be positioned for the
desired torque. The longer the handle arm,
the greater amount of torque can be applied.
Handle Adjustment
Operating this equipment has the potential
to cause flying debris which may cause eye
injury. Always wear safety glasses or gog-
gles when operating equipment. Everyday
glasses or reading glasses only have
impact resistant lenses, they are not safety
glasses. Be certain the safety glasses you
wear meet the appropriate standards of the
American National Standards Institute
(ANSI).
