-A BRIEF NOTE BEFORE BEGINNING-
Calibration on these models is a way to make small adjustments to burr spacing. This
adjustment is included in the design of the grinder for our factory to compensate for tolerance
stack-up which enables us to provide a consistent product. In general, your grinder should not
need recalibration. If you are experiencing a shift in grind performance, please rst follow our
troubleshooting guide referenced above.
Remove the case using our Case Removal guide.

Rotate the black
adjustment ring until the
three windows in the
white calibration ring are
accessible.
A #0 Phillips screw will
be in one of the three
windows. We opened up
this grinder to nd it in the
middle window.
Remove the screw. Note
that there are two holes
that the screw can be
threaded into.
Here, the windows (obscured in this
view) are on the left side of the grinder
for easiest access.

Placing the screw in the
left window results in a
coarse calibration.
Placing the screw in the
right window results in a
ne calibration.
IF CALIBRATING FINE,
ENSURE THAT BOTH
HOLES ARE VISIBLE IN
THE RIGHT WINDOW.
Setting the screw too
far to the right may
result in separation
of the calibration ring
and adjustment ring.
If your rings separate,
see our Adjustment
Ring replacement
guide.
To adjust your calibration,
hold the white ring with
one hand, keeping it
from rotating. Using the
other hand, turn the black
ring to reposition the
screw hole to the desired
location.

Only one hole is visible - the rings will
separate and compromise grind quality.

Insert the screw and
tighten until the screw
head makes contact with
the white calibration ring.
Rotate the adjustment
system fully counter-
clockwise.
Install the case and return the unit to operation.

** Be careful not
to over-tighten the
screw. This may
puncture the black
adjustment ring and
impede ring burr
tment. **
