Caution!

All extruder parts can be hot!

  1. Using the hex key from the Supply Kit, unscrew the side screws of the fan shroud 
  2. Disconnect fan shroud from the printhead 
  3. Heat an extruder in order to melt remaining plastic possibly blocking the nozzle thread.
  4. Unscrew a nozzle from an extruder using a 7 mm wrench for the plastic, and 10 mm wrench for the composite nozzle.
