bly and pull down the assembly as shown in the picture

from extruder circuit board. Gently pull the wires out of

the green terminal block.

d. Unplug the thermocouple connector (white) from the ex-

truder circuit board as shown in picture below.

e. Push down nozzle tube and pull from bottom. (Note:
