MAINTENANCE
- Install the auger in the extruder. Make sure the grooved extruder profile properly mats with the auger. Make certain
the cover on the extruder head is completely tightened (make sure the auger is fully in).
- Install the filter (3).
- Install the heating element (9).
- Install the flange with the volumetric pump by fully tightening the screws (2) (when tightening, always work on the
diagonally opposite screw so that the filter is tightened evenly; once installed check the distance between the two
flanges with a thickness gauge to make sure installation is correct).
- Remove the two eyebolts and tighten the mounting screws (7) for the pump cover.
- Install the heating elements (8).
- Install the two thermocouples BT6 and BT7.
- Install the pressure transducers (4), screwing the probe attached to the pump and quick-connect coupler. Be careful
not to twist or bend the transducer cable.
- Attach the connecting tube to the extruder, tightening the nuts (6).
- Move the tube near the nozzle body and connect by tightening the screws (13) (make sure the ball is aligned with
the nozzle body).
- Connect the tube’s cables to the relative boxes.
- Put on the covers.
- Connect the thermocouple to the nozzle.
- Put on the covers (10).
- Remove the plate for the fixture used to remove the auger. Tighten the three screws used to secure the plate.

ATTENTION!
If the extruder auger cannot be installed, proceed as directed below:
- Make sure the extruder chamber the auger is mounted on is not dirty.
- If the auger cannot be installed even after the extruder chamber has been cleaned, remove the auger, connect
the thermocouples and heat up the extruder (approximately 200
°
) to expand the chamber; when the extruder is
hot and power to the machine is turned off, install the auger.
