8. Movable blade with slot to prevent the articulated joint from turning if the articulated joint is
damaged, use a (complete) new one (Item no.: see Section 5.2
) or clean the residues of Loctite
from the thread of the existing articulated joint pin.
CAUTION
Tighten the screws to the correct torque -> see Table, Fig. 5.4.2. 5
Æ Apply a small amount of Loctite no. 243 (Item no.: see Section 5.3) to the thread.
Æ Take note of the following WARNING. If the enamel on the one-way restrictor is damaged use
a new "short-stroke cylinder".
DANGER
One-way restrictors are not to be set on the machine. This is only permitted at the factory.
For this reason the replacement short-stroke cylinder must always be installed, together with the
new, already adjusted restrictors attached to it. 5
Æ Screw the articulated joint into the short-stroke cylinder.
Æ Turn the articulated joint into the mounting position (see Fig. 5.6.4, diagram on the left).
Once the cylinder is installed, the slot in the moveable blade prevents the articulated joint from
turning.
Æ Copy the exact mounting position of the proximity switch to the short-stroke cylinder (feeler
gauge, fine-tip marker).
Æ Install the prepared cylinder - complete with one-way restrictors - on the cutter, in the correct
rotational position for the articulated joint.
Æ Fasten the cylinder in this position with the 2 screws M5x65 (Fig. 5.6.3 -> 2) provided.
Æ Install the proximity switch (article no. see Section 5.2) precisely in the position you marked on
the short-stroke cylinder with the permanent marker (see Fig. 5.6.3
-> 4, 5).
Æ Connect the compressed air hoses to the one-way restrictor on the cylinder, in the correct al-
location (see markings). For allocation details please refer to Fig. 5.4.2
-> 6, 7, 8.
Æ Perform the following steps as described in Section 5.6.2.1:
Æ Fasten the moveable blade to the articulated joint.
Æ Re-install the empty-tape duct on the machine frame (2 screws each on LH and RH, see Fig.
5.4.1 -> 6, 9).
Æ Check the gap between the leading edge of the tape deflector and the "empty-tape baffle, in-
side", as described in Section 5.6.6
.
Æ Check the switching points of the proximity switches, as described in Section 5.6.5.

NOTE:
If the tapes are not cut correctly even though the switching points are set properly and the short-
stroke cylinder has been exchanged, complete with the one-way restrictor, the cause of the prob-
lem may be:
incorrect compressed air level/ leaking compressed air connection or Y-socket union, blade in
poor condition, faulty solenoid valve or a break in the drive circuit of the solenoid valve. 5
Æ Perform the appropriate "Final Steps" (see Section 5.6.8).

WARNING
You might cut yourself on the blades and the tape deflector.
Never reach into the pneumatic cutter from below or into the empty-tape duct from above. 5
The cutter remains installed in the machine. 5
Æ Turn the machine and then the compressed air ON.
Æ Disconnect the movable component changeover table from the machine and move it out of the
machine.
Æ Turn the machine OFF.
Æ Remove the cover from the control board.
Æ Carefully undo the cable ties (left and right) on the outside of the control board box (see
Fig. 5.6.7
-> 10).
-> Do not damage the cables in this process.
Æ Mark the allocation of all plug-and-socket connectors and disconnect all plug-and-socket con-
nections on the control unit (see Fig. 5.6.5
).
Æ Disconnect the control unit (box) from the support bar by pushing both of the spring-mounted
elements away from the ba.
Æ Install the new control unit (Item no.: see Section 5.2), correctly rotated and positioned, on the
bar and engage the unit.
Æ Mount an adhesive fixing pedestal for cable ties on the outside LH and RH side of the control
board box (see Fig. 5.6.6
for location).
