How to check the rear impeller fan and replace it in the Aillio Bullet R1 Coffee Roaster
Aillio Bullet roasters shipped in Jan. 2019 came with a separate impeller fan. We suggest replacing the one that came preinstalled in the machine.
It will make future maintenance a lot easier. Use the included #2 hex/allen wrench to loosen the set screw holding the preinstalled fan onto the shaft. Slide the fan off of the shaft. You might need to put a little downward pressure on the fan to get it past the frame.
Slide the new fan onto the center of the shaft and tighten the set screw. The Bullet in this video is version 1/1.5. There are minor differences between this and the current model.
