7. Perforating
Instructions for using the tools
•The hole diameter must not be smaller than the thickness of the material.
Failure to observe this rule will result in damage to the tool.
•It is impermissible to enlarge holes using the progressive die technique.
Similarly, the minimum distance between two holes or between a hole and the edge of the busbar
must be at least the thickness of the tool.
Failure to observe this rule will result in damage to the tool.
•Change tools as soon as they become worn.
Excess wear on a tool may cause the upper tool to become caught in the workpiece, and it may not
be possible to wipe off the workpiece. The tool may be damaged when it is released.
•Keep tools cleaned and oiled when not in use.
The tool life is increased by wetting it with a few drops of oil from time to time.
Storage of tools:
The upper tool must not be inserted into the lower tool, as this may damage the cutting edges.
Installing the upper and lower tools
•Push the piston (12) in the direction of the arrow.
•Insert the upper tool (10) through the aperture (D) into the perforating tool.
•Tighten the upper tool (10) using the cheese head screw (8).
•Pull out the piston (12) in the opposite direction to the arrow.
•Insert the lower tool (11) into the aperture (D) as shown in the diagram.
•Secure with the grub screw (9).
•When removing, proceed in the reverse order.

Profile tools
Upper tools have a straight pin on the outer diameter. To align the upper tool, there are 2 grooves
in the upper tool holder.
Lower tools have two V grooves on the outer diameter arranged at 90° to one another. When
fitting, each V groove (depending on the required perforation or the alignment of the upper tool)
must be aligned with the grub screw (9).
CAUTION!
Breakage and risk of injury from
incorrect alignment of upper and
lower tools during installation.
The upper tool might break when it moves
onto the incorrectly fitted lower tool.
Therefore:
– Ensure that upper and lower tools are
properly aligned when fitting profile tools.

8. Bending
Installing the bending device
•Insert the bending device (7) into the guide (B).
Bending
The bending angle is adjusted using the stroke limiter (25).
The millimetre scale indicates the amount of forward stroke.
The correct settings for the required bending angle should be determined by means of test bends (see
table).
•Insert busbar.
•Determine the shank length.
•Adjust the stroke using the stroke limiter (25).
Setting example for a stroke of 40 mm:
a) For bending, the indexing bolt (3) must be locked into the U groove. If this is not the case,
rotate the indexing bolt (3) through 90° and lock into the U groove (see page 3).
b) Rotate the adjusting spindle (9) until the setting is 40 mm.
c) Press the foot-switch and hold until the hydraulic unit switches itself off.
d) Take the busbar out of the tool.
e) Measure the angle of bend.
f) If the required angle was not achieved, set a larger stroke.
g) Repeat the procedure for as long as necessary until the desired bend angle is attained.
h) From then on, all bent busbars made of the same material and with the same dimensions
will have the same angle. The angle will not need to be adjusted for these particular busbars.
The following table shows the angle of bend depending on the set stroke.
