Tools Required: #2 Phillips screwdriver, large flat blade
screwdriver
1. Unplug the machine.
2. Remove the front panel. Shut off the bean flow to
the grinder. Single bean units require you to pull
the bean shut-off valve forward. Dual bean units
require you to push the bean shut-off valve back
into the slots in the hopper.
3. Remove the hopper cradle. Remove the two screws
in the front, lift the front of the cradle, and slide
cradle back about an inch to disengage the hopper
clips. Then lift the hopper cradle assembly off of the
machine.
4. Remove the spray head. First remove the spray
deflector by spinning it clockwise. Second, pull the
spray nozzle away from the mounting sheet.
5. Remove the grind cap by loosening the 2 screws and
rotating the grind cap away from the screws.
6. Pull out the revolving burr and feedworm assembly.
The sweeps on the revolving burr and feedworm
assembly must line up with the cut outs on the
grind head.
7. Remove the shear cap and broken shear plate.
8. Slide the rotating burr onto the motor shaft,
aligning up the sweeps with the cutouts on the
grind head. Rotate the burr so that the burr is held
back into the burr pocket by the sweeps on the
grind head lip. Slide the drive coupler into place.
Rotate the slot on the drive coupler with the
feedworm. Insert a new shear plate.
9. Reassemble the remaining components in reverse
order of disassembly.
The air shutter feature on the Grind’n Brew® prevents
moisture from entering the grinding chamber and
delivery chute. A gentle airflow exiting the grinding
port as shown indicates proper function of the air
shutter. Lightly moistening your hand before checking
the airflow will help in the detection of the gentle
airflow.
