When heated the hot end is extremely hot - take extra care when
loading filament to prevent contact and avoid serious burns.
Loading filament can be tricky but is made much easier by understanding what is
going on inside the extruder while you try to load filament. The image below shows the
extruder assembly of your Zinter
®
Freedomboth with the Fan and Heat sink removed
and complete and with key parts identified.
1: To load filament first ensure you begin by straightening out approx 5 - 10 cm of
filament
2: While depressing the tension release lever insert filament through the Filament
Access hole in the top of the extruder assembly.
3: Now carefully feed the filament in through the feed roller and into the end of the
Guide Tube - This is quite fiddly, but gets easier with practice! This will be easier if you
have cut the filament end at 45
o
to create a ‘point’.
4: The printer is now ready to print.
