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.
