"Assemble the tube at the top of the nozzle, referring to following."
1. After assembling the tube through the tube guide, route the tube to the front and the nozzle cable to the rear as shown below.
Pay attention to the location of the tube and nozzle cables.
Twisted tubing can cause filament feeding issue.
2. Push the tube to the end of the nozzle tube fitting and check assembly.
Gently try to pull the tube out of the nozzle.
If the tube comes out of the nozzle, there may be a problem with the filament feeding, so push it all the way in to assemble.

If the snap ring is removed, the tube guide will not be secured.
