Caution: Make sure filament is removed, the Ultimaker is turned off
and power supply disconnected before you start the replacement.
Ensure the nozzle is completely cooled down to avoid a risk of
burns.
Tip: It is advised to perform the Atomic Method before starting this
repair. Filament stuck in between the hot end parts can act like glue,
making it very difficult to disassemble the parts.
