1. Unplug the power cord.
2. Empty the hopper of beans.
3. Remove the housing cover, held in place by two
slotted screws.
4. Take off the shear cap. Pull out the feed worm/
grinding burr assembly. These parts are slipped
together and usually come out in one piece.
5. Discard the broken shear disk.
6. Clean out the housing. Look for and remove any
debris that may have caused the shear disk to snap.
7. Reinsert the feed worm/grinding burr assembly on
the motor shaft.
8. Slide the shear drive through the center hole on the
feed worm/grinding burr assembly. The end with the
large slot goes in first. Align this slot with the
tongue on the motor shaft as you push in the shear
drive.
9.Rotate feed worm/grinding burr assembly to align the narrow slot with the narrow slot on the shear drive.
10. Insert a new shear disk into this slot and cover with the shear cap.
11. Clean off the inside surfaces of the housing cover. Replace the housing cover. If the housing cover doesn't seat properly, the
shear drive is probably not aligning with the motor shaft (repeat step 8).
12. Plug in the power cord.
Pour whole bean coffee
through the door on top of
the grinder.
