Æ Undo the fasteners for the stop buffer assembly on left- and right-hand side of the machine
frame (two M8 socket hex head cap screws on each side, see Fig. 5.4.1
-> 15) under the
surface supporting for the component table.
Æ Loosen the screws fastening the cutter to the machine frame (2 screws, M6, on the left and
right retaining bracket, see Fig. 5.4.1
-> 2, 3 and 4):
In exceptional cases, disks or plates may have been installed between the contact surface
of the cutter on the machine frame and the cutter itself.
-> Save these disks / plates and re-install them later.
Æ Securely hold the cutter tight at both ends.
Æ Pull the cutter out away from the contact surfaces (on the machine frame) towards the outside
of the machine (towards your body).
Æ Set the cutter down such that it does not pose a risk of injury to uninvolved personnel either.
Put it in its own crate / container immediately.
5.6.1.2 Installing the Cutter
Æ Make certain that the following warning signs are on the cover plate over the movable blade.
If not, install them (Item No.: see Section 5.2):
Adhesive Label with text " Disconnect machine from mains voltage and....",
Adhesive Label: Triangle warning symbol "Hand injury".
CAUTION
Tighten the screws to the correct torque -> see Table, Fig. 5.4.2. 5
Æ If there were disks or plates inserted between the contact surface of the cutter on the machine
frame and the cutter itself, re-install them now.
-> The cutter must be shimmed to the same height at all contact points however.
Æ In the reverse order to disassembly, place the new pneumatic cutter (Item no.: see Section 5.2)
on the contact surfaces of the machine frame and push it in to the threading position.
Æ To avoid dropping the cutter, insert all four M6 screws into the holes now:
Æ Pull the cutter as far as possible away from the PCB conveyor for the time being.
Æ Snug up the screws somewhat for the time being.
Æ Remove the cover from the control board of the new cutter.
Æ Make the plug-and-socket connections for the power supply and drive on the control board (al-
location: see Fig. 5.6.5
-> 11, 10).

Æ Use a cable tie to fasten the cables running to the cable pit to the fixing pedestal on the control
board box (see Fig. 5.6.5
-> 15).
The strain on the cables / plug-and-socket connections must be relieved (see Fig. 5.6.7
-> 8).
Æ Remove the cover from the cable pit and make the compressed air connection to the machine
at the Y-plug-in coupling (see Fig. 5.6.3
-> 9).
Æ Place the cover back on the control board and the cable pit.
Æ Install the empty-tape duct assembly and check the entire length of the gap between the lead-
ing edge of the tape deflector and the "empty-tape baffle, inside", as described in Section 5.6.6
.
Æ If necessary, slide the cutter in the slots parallel to the direction of the PCB conveyor until you
reach the TARGET distance 1.0 to 1.5 mm (see Fig. 5.4.2
-> Detail).
Æ In this position tighten all 4 screws crosswise.
-> Tighten the screws to the correct torque -> see Table, Fig. 5.4.2
.
Æ Perform the appropriate “Final Steps” (see Section 5.6.8).
