PRESS BRAKE SET-UP
Do not bend material larger than 12” 20-gauge mild steel.
Failure to comply may cause serious injury and/or damage to the
machine.
To set up for bending:
1. Place a strip of wood (F, Figure 5) on bottom die, the full length of die.
2. Close brake until the wood contact supper dies(E).
3. Loosen screws (D) using 5mm hex key.
Figure 5
4. Select upper dies (E) for desired job and remove the others by sliding
them out the left end.（Included die set sizes1”x1, 2”x2, 3”x1, 4”x1）
5. Move operating handle until the wood pushes up the dies so that they
seat uniformly in upper beam.
6. Securely re-tighten all screws (Figure3), then release and remove wood
strip.
7. If making repeated bends or using along workpiece, position guide rods
and plate for brake operation, as shown in Figure 3.
8. Scribe a line on workpiece for bend location. (Be sure to accommodate
bend allowance based on thickness of material. This can be done either

- 8 -
through trial and error, or by consulting a machinist’s handbook.)
9. Rest workpiece on v-block (lower die)so that the scribed line is aligned
with the tips of upper die(s).
10. Hold workpiece steady and use operating handle to make bend.
To adjust brake beam (G, Figure 6) for90° bends at bottom of stroke:
1. Slightly loosen locking screws (H)using 6mm hex key.
2. Turn brake beam adjusting screws (G)with 16mm wrench, until test
bend reflects 90° bend at both ends of brake.
3. Re-tighten screws (H).
Figure 6
For special repetitive bends, the brake beam may be adjusted to over-bend
the desired angle since the metal will have some degree of “spring back”.
Shear set-up
Do not shear material larger than 12” 20 gauge mild steel.
Failure to comply may cause serious injury and/or damage to the
machine.
1. Install guide rods and plate in shear position (Figure 4) and adjust to
desired length of workpiece cut.
2. Place workpiece against guide block at right edge of table (K, Figure 7).

- 9 -
The end of workpiece should be against guide plate.
3. Operate handle to begin shearing cut. Shearing action progresses from
right to left.
NOTE: 1. To prevent distortion when notching, “snap” the handle to
facilitate piercing.
2. Do not reach behind the machine to catch the cut-off piece. A large
cut-off piece should be allowed to drop onto a special table designed to
catch pieces that are bigger than the workbench.
3. Large pieces being cut may require a front table to support the piece.
4. All metal cut on this machine will have a sharp edge. File or sand the
sharp edge before handling to avoid injury.
Figure 7
Lower Blade Adjustment
Upper and lower shear blades have been factory aligned and should not
require immediate adjustment. Should re-alignment be needed in the
future, proceed as follows:
1. Place a heavy sheet of paper in the cutting position, along entire length
of bed, and make a cut.
2. If the shear does not cut the paper,loosen screw (L, Figure 7) at each
end of table, with 6mm hex key.

- 10 -
3. Rotate adjustment screws (M, Figure 8)to shift table and change the
gap between blades. Do not allow the blades to overlap.
4. If the shear cuts the paper on the ends, but not the center, slightly turn
screw (N,Figure 9) clockwise until paper is cut the entire length.
Figure 8
5. If the shear cuts the paper in the center, but not the ends, turn screw
(N)counterclockwise until paper is cut the entire length.
Figure 9
Blade Rotation/Replacement
Exercise caution when working with or near the blades. Use
work gloves when handling them.
The shearing blades are reversible and interchangeable; when the edges
dull, rotate them to the new edge, as follows:
1. Remove hold-down by loosening screws (O, Figure 10), using 10mm
hex key.

- 11 -
2. Raise upper blade to highest position.
3. Remove 4 screws (P, Figure 10) and carefully remove blade.
4. Rotate or replace blade and re-install screws (P).
5. Re-install hold-down. When blade is in highest position, the gap
between the hold-down and the table should be within1/4. Adjust to this
position by turning the wo screws (O, Figure 10) as needed. When the
blade starts its downward travel,the hold-down should immediately hold
workpiece in place.
Figure 10
Slip Roll set-up
Do not roll material larger than 12” 20-gauge mild steel. The
slip roll guard must cover the rolls except when material is being fed
into the rolls. Failure to comply may cause serious injury and/or
damage to the machine.
Material Size Conside rations
To determine approximate length of material needed for a desired size tube,
use the following formula :
C =πD
Where C is the circumference, π equals3.1417 and D is the diameter. For
example: To find the length of material needed (C) to form a tube 4" in
diameter, multiply 3.1417 by 4". Result:12.5667" is the circumference of

- 12 -
approximate length of material needed. Cut several pieces of material to
this length for a forming test run. Material may have to be lengthened or
shortened depending on results of test run.
TIP: If it doesn’t interfere with the proposed final shape or design, a slight
bend made with the press brake on the leading edge will simplify the initial
rolling process, by allowing the leading edge to slip more easily over the
idle roll.
Beware of pinch point –the intersection of upper and lower rolls.
Failure to comply may cause serious injury to fingers and/or hands.
1. Make sure rolls and workpiece are clean and free of debris to prevent
pitting of sheet metal.
2. Back off idle roll completely by rotating idle roll screws (Q, Figure
11)counter-clockwise.
3. Loosen bolt (R, Figure 11) to increase space between upper and lower
press rolls.
Figure 11
4. Insert material between upper and lower rolls, and tighten bolt (R,
Figure 11)to lower the upper roll, until material fits snugly. The upper roll
must have sufficient pressure on workpiece to feed properly.
5. Rotate both idle roll screws (Q, Figure11) to adjust idle roll’s proximity to
the two main rollers. Raise both ends an equal amount.

- 13 -
6. Run workpiece through the machine using the handles. If workpiece is
large, make sure it receives proper support as it exits the machine.
7. Make further passes of workpiece, raising the idle roll incrementally
before each pass, until desired radius is achieved. No exact formula can be
followed when making roll adjustments because material “spring-back”
varies with the kind of material being formed. Only by test forming several
pieces can correct adjustments be obtained. Also, keep in mind that it is
much easier to re-pass material to make a smaller radius than to attempt to
increase a radius that was made too small.
The idle roll must be adjusted exactly parallel or the material will spiral
during the rolling process. Measure each end of the opening with calipers if
greater precision is required.
Deliberately setting the rolls non-parallel can be used to make cone
shapes.
To remove cylindrical shaped workpieces:
1. Loosen bolt (R, Figure 12)
Figure 12
2. Carefully grasp upper roll and swing out the end. Grasp upper roll firmly,
to prevent it falling out of machine.
3. Slip workpiece off end of roll.
4. Re-install upper roll, and tighten bolt (R, Figure 12).

- 14 -
Flat Rolling
Softer metals (copper, aluminum, etc.)can be processed through the slip
roll machine to straighten, flatten, or reduce their thickness. Simply adjust
the upper press roll for thickness, lower idle roll all the way down, and feed
workpiece through (Figure 13).
NOTE: The idle roll will not descend completely out of the path of the
workpiece; thus, there may be a slight bend in the workpiece. By flipping
the workpiece over and re-feeding it, this bend can be minimized.
Figure 13
Forming a Radius
1. Adjust upper press roll as needed.
2. Insert workpiece from front.
3. Operate handle; when the material reaches the point where the radius
is to begin (a, Figure 14), stop the machine and raise the idle roll an equal
amount on each end to achieve desired bend.
Figure 14
4. Restart rolls and continue until bend is completed (b, Figure 14).
Support workpiece as it exits machine.
5. Make further passes if needed, along with incremental idle roll

- 15 -
adjustments.
Forming a Tube
1. Adjust upper press roll as needed for workpiece thickness.
2. Feed workpiece into machine. As it nears the end (a, Figure 15), stop
and reverse direction (b, Figure 15).
3. Make further passes if needed, along with incremental idle roll
adjustments.
Figure 15
Bending Wire
There are 6 wire grooves at the ends of the press rollers to accommodate
a2.99mm(0.12”), 3.66mm(0.14”), 6.1mm(0.24”), 3.05mm(0.12”),
4.40mm(0.17”), 5.16mm(0.20”)wire.
Use the smallest groove into which the wire will comfortably fit. Bend the
wire using the same principles as described for forming a radius. To make
a complete loop of wire, use the instructions for forming a tube.
Maintenance/Lubrication
Use caution when doing maintenance work around the shear
blades.
1. Apply #2 lithium tube grease once a month to the grease nipples on
both ends of frame (A, Figure 16).
2. Keep the slip rolls clean and rust-free, and frequently apply a light coat

- 16 -
of oil to them.
3. Lightly brush multi-purpose grease onto the gears at the end of the
rollers (B, Figure 16). Turn operating handle to distribute the grease.
4.Keep other exposed areas clean and lightly coated with oil, such as the
shear blades, table and upper dies. (Remove upper dies from bar for more
effective cleaning).
