REPLACING THE GRINDSTONES
IMPORTANT: always change both 2 grindstones (9) at the same time.
The 2 grindstones are identical and can be fitted equally either on the moving plate (18) (moving grindstone) or
on the adjusting “nut” (5) (fixed grindstone) (fig. F).
1.
Close the bean shutter (6) (fig. G).
2.
Run the machine until the coffee beans waiting in the grinder body have gone through.
3.
Stop the machine and unplug the mains power lead (10).
4.
Take off the bean container (2).
5.
With one hand, press on the indexing pointer (7) and with the other unscrew the adjustment nut by turning
it in an anti-clockwise direction (fig. H).
CARE: When this part is fully unscrewed, handle it with care so as not to damage the brass thread.
6.
Unscrew the 3 screws on each grindstone (fig. I). For the moving grindstone, place a screwdriver
across the grinder body and the coffee outlet conduit to stop the grindstone-carrier plate from turning on
unscrewing or screwing up the grindstone retaining screws.
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 grindstone-carrier plate (18) retaining spindle (17) so as not to upset the
assembly geometry (fig. J).
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) on 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. K).
10.
Unscrew the “adjustment nut” (5) 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.
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. L).
