13.The sound of the burrs touching while spinning is unmistakable. It’s a high-pitched
metallic “chirp” plainly audible over the sound of the MDF motor.

rotate the bean hopper either clockwise or counter-clockwise until absolute zero is
located by the telltale “chirp”.

Sometimes a false “chirp” can be heard. Another way to ensure that the burrs
are at absolute zero is to listen for the sound after you switch the grinder off. It the
motor sounds like it is winding down, then the burrs are still freely spinning. If the
motor stops immediately, then the burrs are touching.

REASSEMBLY
16.Remove bean hopper.
17.Replace adjustment ring. The #1 or absolute zero setting should be facing front.
Screwing the two brass hex bolts back into place will secure the adjustment ring.
18.Return the faceplate to the machine. Tighten the two small Phillips head screws back
into place. The #1 on the adjustment ring should be centered in the window of the
faceplate.
**It is alright if the adjustment collar is slightly off. The most important thing is that
the grinder is recalibrated properly.
19.Replace the bean hopper, the two bean hopper screws and the two rubber stoppers.
20.Plug in and check machine operations.
