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 elements (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).
- Screw the cover on the extruder assembly with the screws (11).
- Turn on the machine with the main switch.
8.1.2.3.2 Checking the oil level in the extruder geared motor and topping up
- Make sure the oil level, shown by the gauge (28), is correct. If it is not, top up as follows:
- Take off the cap (29).
- Add oil until the correct level (28) is reached.
- Screw the caps (29) back on.
8.1.2.3.3 Changing the oil in the extruder geared motor
- Take off cap (29).
- Take off cap (30) and drain the oil from the geared motor.
- Put the cap (30) back on.
- Add oil until the correct level (28) is reached.
- Screw the cap (29) back on.
8.1.2.3.4 Cleaning the polymer metering pump
- Remove all the plastic that flows out of the pump (5) being careful not to cut the pressure transducer and heating
element cables.
8.1.2.3.5 Replacing/overhauling the polymer metering pump
- Remove the plastic compound from the auger chamber with the extruder at its operating temperature. To do this,
carry out a by-pass operation until the plastic compound no longer flows out of the nozzle.

ATTENTION!
Stop feeding plastic compound to the extruder when cleaning.
- Shut off the machine with the main switch located on the electrical cabinet.
- Install the guide extensions provided.
- Disconnect the pressure transducers (4) by loosening the quick-connect couplers found under the extruder
mounting bracket. Loosen the probe attached to the pump being careful not to twist or bend the transducer cable.
- Take off the cover (10).
- Disconnect the cables from the electrical boxes with the quick-connect couplers.
- Remove the thermocouple (15) mounted on the nozzle body.
- Take off the covers that protect the connecting tube (14).
- Loosen the screws (13).
