Tools Required: Phillips Screwdriver and Pliers

1.Unplug machine.

2.Remove the Upper Front Plate of the grinder to provide access to the grinder mechanism.

3.Remove the Grind Cap by taking out the 2 Thumb Screws.

4.Pull out the Revolving Burr and Feedworm Assembly. Clean out the Grinder Head, removing all coffee parti- cles from inside of the Grinder Head and the Grinder Cap so that it can be reset properly.

5.Check that no obstruction has been caught on the surface of the teeth of either burr.

6.Remove the Shear Cap and broken pieces of the Shear Disc. You are now ready to reassemble the grinder mechanism.

7.Slide the Burr and Feedworm Assembly back onto the Motor Shaft making certain that the tongue of the shaft engages the slot in the Shear Drive.

8.Insert a new Shear Disc by aligning the slot in the Shear Drive with the slot in the hub of the Feedworm.

9.Reassemble the Shear Cap and Grinder Cap. Make certain the Grinder Cap is screwed on tight and is sealed properly against the head, not cocked. Otherwise a proper grind cannot be obtained.
