This machine is shipped from the manufacturer in
a carefully packed carton. If you discover the
machine is damaged after you’ve signed for deliv-
ery, and the truck and driver are gone, you will
need to file a freight claim with the carrier. Save
the containers and all packing materials for pos-
sible inspection by the carrier or its agent.
Without the packing materials, filing a freight
claim can be difficult. If you need assistance
determining whether you need to file a freight
claim, or with the procedure to file one, please
contact our Customer Service. Piece Inventory

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).

-6- G4011 30" Sheet Metal Machine
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.
2. 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.

G4011 30" Sheet Metal Machine
In order to do rolling operations, move the cover
back and out of the way.
1. Drop the rear roll bar by loosening the adjust-
ment knobs.
2. Insert just the leading edge of the workpiece
between the upper and the lower roll bars,
and tighten the roll bar gap adjustment keys
until the roll bars are barely snug against the
workpiece.
3. Advance the adjustment knobs 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.
Rolling
Lubrication
Grease the crank arms as necessary using a
grease gun on the installed grease fittings. Do not
over-grease.
A light coating of oil on the area where the upper
arm slides will also assure ease of movement.
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 measure-
ment 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 posi-
tion.
3. Using the handle assembly, raise the cross
beam 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 work-
piece, simply loosen the bolts that hold the
upper braking die brackets 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 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 that hold the upper die
bracket in place and allow the dies to drop slight-
ly until they contact the block. Tighten the upper
bracket bolts.
