  8. Transfer the washer from the old nozzle to the new nozzle. Take care not to lose it.
  9. Apply a small amount of Anti-Seize to the end of the threads of the new nozzle, then press Next on the touchscreen.
    Note: Be sure not to get any of the Anti-Seize inside the nozzle.

  12. Using the torque wrench, screw the new nozzle partway into the print head, then unscrew it and screw it in again; this helps disperse the Anti-Seize over all of the threads. Press Next to continue with the utility.

  13. Once the print head finishes heating, tighten the nozzle until it clicks.
    Note: Be sure the torque wrench has solid contact at all points on the nozzle. Failure to do so may result in your plastic nozzle being stripped.
