This is how to adjust coarseness and timer for the old version of the Bunn G9 grinder. The instruction manual is written very poorly and there are no videos out there showing you how to do this, so I had to figure it out myself.
You’ll need a 24mm socket to loosen the coarseness adjustment screw nut, and a flathead screwdriver for all screws.
The timer is located behind the faceplate beneath the chute opening. You’re welcome in advance 😂✨☕️
