3. Stop the machine and unplug the mains power lead (10).
4. Take off the bean container (2).
5. With one hand, press the indexing pointer (7) and with the other unscrew the
adjustment nut by turning it in an anti-clockwise direction (fig. I).
Care: When this part is fully unscrewed, handle it with care so as not to damage the
brass thread.
6. Unscrew the three screws of each grinder (fig. J). For blocking the rotation of grinder
holding plate while unscrewing or screwing the fastening screws of movable grinder,
place a screwdriver, non aggressive, between the grinding body and one of the fins
of the plate.
ATTENTION: Do not introduce the screwdriver in the coffee output hole.
This may destroy the anti-static strip and damage the operation of the
equipment.
7. Carefully clean the whole grinder body, in particular the grindstone facing areas.
8. Place each grindstone on its support making sure that there is no coffee dust
between the grindstone and its support.
CARE: The slightest small coffee particle under the grindstone may
prevent the machine from operating correctly. It is recommended that the
grinder body is cleaned with a compressed air jet or a dry brush.
CARE: Do not unscrew the retaining shaft (17) from the grindstone
carrier plate (8) so as not to upset the assembly geometry (fig. K).
9. Once the 2 grindstones have been replaced, with one hand press the indexing
pointer (7) and with the other place the ground coffee adjustment nut (5) onto the
grinder body taking care not to damage the thread. Without using force, put the "nut"
(5) on the grinder body unscrewing it gently to feel for alignment of the two threads
and thus to be able to feed them in without using force. Then tighten until the 2
grindstones come into contact (fig. L).
10. Unscrew the "adjustment nut" (5) by ten or so notches to free the grindstones in
contact.
11. Plug the machine in and switch it on with no coffee.
12. While pressing the indexing pointer with one hand, with the other screw up the
"adjustment nut" (5) until the 2 grindstones make slight contact (slight noise).
13. Stop the machine.
14. Unscrew the graduated plate (12) retaining screws and re-index the graduated plate
"0" with the indexing pointer (7) (fig. M).
15. Loosen the "adjustment nut" (5) by 5 to 10 notches.
16. With coffee in, adjust the ground coffee setting (see "Grinding adjustment"
section).
17. Next, set the timers if the new grindstones have changed the machine output (see
"Setting the measured dose of ground coffee" section).
