Before Each Use
Check for damaged parts before each use. Carefully check that the tool will operate properly
and perform its intended function. Replace damaged or worn parts immediately. Never operate
the tool with a damaged part.
Operating Instructions
WARNING:
The maximum capacity of this machine is 20 gauge mild steel. Exceeding the capacity of the
machine may be hazardous to the operator.
Handle Adjustment
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 (18).
2. Loosen the handle adjustment knob (73) and slide the handle arm out of the slot (35).
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.
Shearing
For precision shearing up to 30’’ width, first attach the back measurement assembly (20, 21, 43)
to the receiver holes in the back of the crossbeam:
1. To adjust the position of the back measurement assembly, first loosen the two knobs (43).
2. Move the assembly forward and back across the threaded rod (19). 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 (16) to the left side of the cutting table (2)
using the two Allen screws (58).
4. Using the handle assembly (18), raise the upper cutting die (23) to the highest position. Slide
the workpiece in between the cutting die (23) and the work surface.
5. Rotate the handle assembly to shear the workpiece at the desired location. During shearing
operations, there are two conditions 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
(22) adjustment bar. Tightening the bolt (47) will cause the ends of the shear to bow out,
loosening the bolt (47) will cause them bow in.
2. Shear Alignment. The two shearing bars (23) 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 (60) that hold the table, then tighten or loosen the adjustment screws (17) on
the front underside until the cutting table is properly aligned. Tighten the holding bolts and
double check the alignment.
Tips for shearing
• When shearing, the work should be squared against the squaring guide (16). The pressing
plate (10) 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 pressing plate (10) 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 designated to catch cut-off pieces that are larger
than the workbench.
• To prevent distortion when notching, “snap” the handle quickly to pierce the workpiece.
• To adjust the lower shear blade (23), loosen the screw (60) at the end of each table.
Underneath the table, there are two adjustment screws (17) 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 professional. This will lead to accurate and quality
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.
Pressing
Slide the plate brackets (11) on the press plate assembly into the receiver holes of the upper
cutting 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.
Braking
For precision braking 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 measurement assembly, first loosen the two knobs.
2. Move the assembly forward and back using the handwheel. When it is at the desired position,
tighten the knobs to lock it into position.
3. Using the handle assembly (18), raise the cross beam (3) up to its highest position.
4. Insert the workpiece in between the upper and lower braking dies.
5. Rotate the handle assembly, using the appropriate amount of force to achieve the desired
bending angle.
6. To bend only certain portions of your workpiece, simply loosen the bolts (53) that hold the
upper braking die brackets (13) in place and add or remove the dies as required. For small
increments, use the fractional dies included with the machine. You should notch the material
appropriately before bending to achieve the good results. This means you will have to make a
cut between the portion of the material to be bent and the portion you wish to remain
straight.
The upper braking dies (12-1,2,3,4,5,6,7) may become uneven. This is best handled with a
wooden gauge block that is the full length of the table and is the same height all the way
across. Raise the crossbeam all the way and slide the block underneath the dies. Loosen the
bolts (52) that hold the upper die bracket in place and allow the dies to drop slightly until they
contact the block. Tighten the upper bracket bolts.
Rolling
In order to do rolling operations, move the cover back and out of the way.
1. Drop the rear roll bar (24) by loosening the adjustment knobs (25).
2. Insert just the leading edge of the workpiece between the upper and the lower roll bars
(32,31), and tighten the roll bar gap adjustment keys (27) until the roll bars are barely snug
against the workpiece.
3. Advance the adjustment knobs (25) as much as desired depending upon the tightness of the
roll to be accomplished. The tighter the roll, the more the knobs should be advanced.
4. Rotate the handle assembly until the proper roll has been achieved. The material will feed
itself through the rollers as the handle assembly is cranked.
Wire rolling is accomplished in the same manner, except the proper groove in the upper roll bar
must be utilized depending upon the wire gauge being rolled.
