WARNING
Wear thick protective gloves
When removing the cutter, hold it only on the left and right, on the outside.
Turn the machine and then the flow of compressed
air ON.
Disconnect the movable changeover table from the
machine and move it out of the machine.
Switch off the supply of compressed air at the com-
pressed air unit and actuate the needle valve on the
compressed air unit to bleed the compressed air
lines.
Turn the machine OFF, disconnect the machine from
the line and turn off the flow of compressed air at the
compressed air unit.
Loosen the screws fastening the empty-tape duct as-
sembly (6) (M6x35), lift the empty-tape duct and
place it carefully down on the PCB conveyor. The
nozzle changer remains fixed to the empty-tape duct.
WARNING! There is always a risk of injuring
yourself on the cutting edge of the blades.
For this reason, the deflector plate, the cover and the pro-
tective sheet must be left in place.
Undo the fixtures for the stop buffer assembly (15)
(two hexagon-socket head screws M8x25 on each
side) on the left and right-hand sides of the machine
base, under the surface supporting the changeover
table.

Installing the Cutter
Make sure that the following warning signs are on the cover plate over the moveable blade (see op-
erating manual) and, if they are not, attach them:
⇨ Adhesive Label with text " Disconnect machine from line voltage and....",
⇨ Adhesive Label: Triangle warning symbol "Hand injury".
WARNING! The area under the cutter must be
clear.
(e.g., do not place your feet under it either).
Loosen the screws fastening the cutter to the ma-
chine base
2 M6x25 screws each (4), on the left (2) and right cut-
ter holders (3).
⇨ In exceptional cases, disks or plates may have
been installed between the contact surface of the
cutter on the machine base and the cutter itself.
-> Save these disks / plates and re-install them lat-
er.
Securely hold the cutter tight at both ends.
Pull the cutter out away from the contact surfaces (on
the machine base) towards the outside of the ma-
chine (towards your body).
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.
NOTICE
If you are installing a new cutter, remove any excess oil or lubrication grease, before instal-
lation.
