WARNING!
E0004P
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.
NOTE: The cutting clearance (Q) should range from 0.02 to 0.05 mm. The cutter (G), when close to the nozzle (N),
rests on the runner (P) which acts as a reference for the height of the cutter.
To adjust or change the cutter clearance (Q), proceed as directed below:
- Place the comparator (R) on the roller holder (M).
- Loosen the screw (O) and lower the runner (P) until the cutter (G) touches the nozzle (N).
- Move the runner (P) up and observe the instrument to make sure that the upward movement of the cutter equals the
desired cutting clearance.
- Fully tighten the clamp screw (O).
