Technical Manual
10.4.2 Replacing the Grinder Blades.
1. Isolate the machine from the Mains power supply.
Push in the bean canister shut-off to close the fresh
beans outlet. Carefully remove the fresh beans canister
from the machine and place it to one side.
Pull up and remove the grinder adjusting wheel
assembly (b) from the rear of the grinder body.
Unscrew the grinder body (c) anti-clockwise and remove
it from the blade housing.
Note: Grinder mechanism removed from the machine for clarity.
3. Take the new grinder body complete with inner grinder ring from the service kit.
Screw the grinder body clockwise into the blade housing until it stops.
Re-set the grinder blades. An approximate starting position is achieved by turning the
grinder body back one full turn anti-clockwise. Re-assemble the grinder adjuster wheel
assembly to the grinder unit.
4. Refit the fresh beans container to the machine. Pull the bean canister shut- off to its
fully extended position.
5. Turn on the electricity supply to the machine.
Important! Before returning the machine to service, the Grinder Calibration routine
(refer to Section 5.7.1.2) must be carried out to ensure correct operation of the
grinder with the type of beans used in the machine. Use the grinder adjuster wheel to
fine tune the blade settings in order to obtain the desired grind quality.

block (e) and discard. Replace with the new grinder blade
block included with the service kit.
Refit the agitator, star washer and nut. Ensure that the nut
is tightened securely.
