NOTE: For brake operation, install guide rods
into upper set of holes (Figure 4); for shear
operation, install in lower set of holes (Figure
5).
12. Install guide plate as shown in Figures 4 or 5.
Secure it to rods using the T-handles.
6.4 Press Brake set-up
Do not bend material larger
than 30” (40”) 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 (D, Figure 6) on bottom
die, the full length of die.
2. Close brake until the wood contacts upper dies
(E).
3. Loosen screws (F) using 6mm hex key.
Figure 6
4. Select upper dies (E) for desired job and
remove the others by sliding them out the left
end.
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 (Figure 4), then
release and remove wood strip.
7. If making repeated bends or using a long
workpiece, position guide rods and plate for
brake operation, as shown in Figure 4.
8. Scribe a line on workpiece for bend location.
(Be sure to accommodate bend allowance
based upon thickness of material. This can be
done either 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 7) for 90°
bends at bottom of stroke:
1. Slightly loosen locking screws (H) using 8mm
hex key.
2. Turn brake beam adjusting screws (J) with
19mm wrench, until test bends reflect 90°
bend at both ends of brake.
3. Re-tighten screws (H).
Figure 7
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”.
6.5 Shear set-up
Do not shear material larger
than 30” (40”) 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 5) and adjust to desired length of
workpiece cut.
2. Place workpiece against guide block at right
edge of table (K, Figure 8). The end of
workpiece should be against guide plate.
3. Operate handle to begin shearing cut.
Shearing action progresses from right to left.
NOTE: To prevent distortion when notching, “snap”
the handle to facilitate piercing.
