Removing the Cutter
X Turn the machine and then the flow of
compressed air ON.
X Disconnect the movable changeover table
from the machine and move it out of the
machine.
X Switch off the supply of compressed air at the
compressed air unit and actuate the needle
valve on the compressed air unit to bleed the
compressed air lines.
X Turn the machine OFF, disconnect the
machine from the line and turn off the flow of
compressed air at the compressed air unit.
X Loosen the screws fastening the empty-tape
duct assembly (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.

yourself on the cutting edge of the
blades.
X For this reason, the deflector plate,
the cover and the protective sheet
must be left in place.
X 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.
X Remove the cover from the control board (14).
