2.11 ADJUST GRINDERS

This is the fi rst step to customizing the machine to the roast of beans to be served. This will need to
be done using the beans that will be served.
TIP: Pull a shot fi rst and see how machine is pouring prior to adjusting the grind.
STEPS FOR ADJUSTING GRINDER WITHOUT GRINDER ADJUSTMENTS INSTALLED
1. Remove the screw holding the front door closed. Swing the door open.
2. Find the grinders on the inside of the machine. On the top of both grinders you will fi nd an
adjustment plate.
3. Insert a fl at head screwdriver into the slot on the adjustment plate. Apply a gentle downward
pressure on the screw driver to lift the plate free of the notches that are holding it in place.
PLEASE NOTE: do no over-bend.
4. Turn the collar on the top of the grinder to adjust the grind.
Finer grind = Turn collar clockwise
Courser grind = Turn collar counter clockwise
5. Make sure that the adjustment plate is securely held in place by the notches before removing the
screwdriver from the slot.
Please note: While one notch is a seemingly small adjustment, it can greatly affect the resulting grind. Use
small turns, one notch at a time, to adjust the grinder burrs until the correct grind is reached.
