• Before cleaning the nozzle, the nozzle must be heated so that the lament can be unloaded from the extruder and
residues be removed.
The nozzle temperature depends on the lament material. Always check the specication of the lament
before replacing the nozzle.
Do not keep the nozzle temperature at 260 °C for more than 10 minutes. After 10 minutes, decrease it to
230 °C and keep it at this temperature for at least 10 minutes before increasing it again. If you consistently
operate the 3D printer at temperatures over 230 °C, the life time of the extruder will drastically be shortened.
In order to (un)load the lament, ensure the nozzle temperature reaches 170 °C or above.
Danger of burns! Do not touch the hot nozzle directly with bare hands.
