Pressing
Slide the plate brackets on the press plate
assembly into the receiver holes of the upper cut-
ting die. Make sure the press plate is facing
down.
Place the workpiece so that it is centered under
the press plate. Rotate the handle with sufficient
force to achieve the degree of pressing desired.

Shear Alignment. The two shearing bars
may need to be aligned with each other
across their entire length. Lower the shear
assembly all the way so the two shears are
even with each other. If one side or the other
does not meet, the cutting table needs to be
realigned. Loosen the bolts that hold the
table, then tighten or loosen the adjustment
screws on the front underside until the cut-
ting table is properly aligned. Tighten the
holding bolts and double check the align-
ment.
Tips for shearing:
•
When shearing, the work should be squared
against the squaring guide. The holdown
should be adjusted approximately
1
⁄
4
" above
the table when the shear blade is in the “up”
position. As you move the blade downward,
the holdown should immediately rest against
the workpiece and hold it in place.
•
Do not reach around the machine to grab the
cut-off piece. A large cut-off piece should be
allowed to drop on a special table that is des-
ignated to catch cut-off pieces that are larger
than the workbench.
•
To prevent distortion when notching, “snap”
the handle quickly to pierce the workpiece.
The maximum notch that can be cut at one
time is
3
⁄
4
". By progressing in
5
⁄
8
" steps, a
deeper notch can be cut.
•
To adjust the lower shear blade, loosen the
screw at the end of each table. Underneath
the table, there are two adjustment screws on
the left and right side. By adjusting these
screws in or out, the lower blade can be
brought in contact with the upper shear so a
fine cut can be made.
•
Have the shear blades sharpened by a pro-
fessional. This will lead to accurate and quali-
ty results.
•
The shear blades are interchangeable. The
upper shear mount has a 5˚ relief angle, so
the upper blade does not exactly match the
lower blade when installed correctly.
All metal parts after shearing will have a
sharp edge on them. The sharp edge may
cause cuts or lacerations when handled.
Please examine the edges of all cut metal
parts and file or sand the edge to remove
the edge before handling.
