Assembly step-by-step guide
Insert the heatbreak into the Heater Block as illustrated below:
Mount the nozzle on the heatbreak using wrench size 8. Grip the heatbreak using pliers.
Make sure the nozzle is firmly mounted to avoid leakage.
Screw the nozzle against the Heater block using wrench size 8.
Cut a piece of 2-3mm PTFE tube in a length of 16mm.
Insert the PTFE tube (cut in previous step) fully inside the heatbreak.
Insert the Setscrew M5x6mm /w hole into the heatbreak using Allen wrench size 2.5.
