10. Open the bean hopper by pulling out the slider.
11. Reconnect the grinder to the power supply and switch on the grinder
(on/off switch(5) in the ON position).
12. Grind 2–3 shots to remove any residue of the old coffee beans, warm
up the machine and prevent any fluctuations in dispensing the beans.
Setting the grinding degree
You can infinitely adjust the desired grinding degree with the grinding
degree adjustment (3).
Read the set value (0–8) on the grinding degree scale, which is located on
the grinding degree adjustment system (3): the higher the value on the
grinding degree scale, the coarser the ground coffee.
You will find guide values for the grinding degrees of the various prepa-
ration types on the spout cover (4). You can use these for orientation
when setting the grinding degree (see Fig.A). The symbols on the spout
cover stand for the following preparation types:
Mocha /
Turkish
coffee
Espresso Filter
coffee
French
Press
• Turn the grinding degree adjustment counterclockwise to increase
the value on the grinding degree scale (for coarser ground coffee).
• Turn the grinding degree adjustment clockwise to decrease the value
on the grinding degree scale (for finer ground coffee).

13
Jack Allround Grinder | EN
Only reduce the grinding degree when the grinder is in operation.
To avoid/eliminate imbalances when setting the grinding
degree, it is advisable to set a coarser grinding degree to begin
with and then reduce the grinding degree adjustment to the
desired finer grinding degree from there.
Grinding process
1. Ensure that the power plug (6) is inserted into a properly installed
grounded socket.
2. Switch on the grinder by placing the on/off switch(5) in the ON

the ground coffee falls directly into the measuring cup from the
spout.
In this respect, undo the two knurled screws (7) and position the
platform at the correct height by hand.
Afterwards ensure that you fix the two knurled screws evenly, so that
the platform is level.
5. Press the release button (11) and hold it down for the duration of the
grinding process.
6. Release the button to end the grinding process.
