This operation must be carried out when the extruder has reached its correct operating temperature.
Carefully follow the instructions given in the SAFETY EQUIPMENT AND PRECAUTIONS chapter, RISKS
DERIVING FROM HIGH TEMPERATURES paragraph and always take the necessary safety precautions to avoid
being burnt.
To adjust the position of the extruder nozzle proceed as directed below:
- Use the handwheel to run the machine until the cutter (G) is brought over the extruder nozzle hole (N).
- Place the comparator (R) on the block which holds the roller (M).
- Loosen the screws (B & D) on the ring nut (I).
- Loosen the screw (O) and completely lower the runner (P).
- Turn the ring nut (I) until the extruder nozzle (N) is brought into contact with the cutter (G). The pointer of the instrument
(R) will begin to move when the two parts begin to touch each other.
- Observing the instrument (R), turn the ring nut (I) to raise the nozzle (N) by 0.2 mm. Allow the roller (M) to move the
same distance away from the cam raceway (L).
- Tighten the screws (D & B) which fix the ring nut and mount respectively.
- Adjust the clearance of the cutter (see relevant paragraph).
