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.

Service Manual SIPLACE D4/D4i 85
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.
