Removing the Extruder
1. Set the main switch (S) on the control cabinet at the back of the machine to O .
2. Remove the three electrical connectors (k) from the back of the extruder: turn
the inner ring clockwise to loosen the connectors from the extruder. It is easier
to start at top and then work your way down.
3. Loosen both extruder attachment screws (c) by turning them counterclock-
wise. Firmly hold the extruder in your hand while doing so.
4. Pull the extruder o the guide rail.
Mounting the Extruder
1. Slide the extruder onto the X-stage mount horizontally to ensure that the
pins line up with the extruder slot (see Fig. 8-5)
2. Tighten the attachment screws (c) by hand to secure
the extruder.
3. Connect the electrical connectors to the back of the
extruder. Use the color code to identify the position of
each connector. It is easier if you start with the bottom
connector and work your way up.
The orientation of the connector is marked by an ar-
row. Locate the connector so the arrows of both sides
of the plug match (see Fig. 8-6)
Secure the connectors by turning the inner ring coun-
terclockwise. Keep the connector parallel to the plug
