Instructions

Replace nozzle
• Before changing or replacing 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.
