T
Choose a spot for your J8 which protects the machine against
overheating. Ensure that the ventilation slots are not covered.
T
Place the J8 on a horizontal surface that is not sensitive to water.
The bean container has an aroma preservation cover. This will ensure
that your coffee beans retain their aroma for longer.
Coffee beans which have been treated with additives (e.g. sugar),
ground coffee or freeze-dried coffee will damage the grinder.
T
Only use roasted, untreated coffee beans to fill the bean
container.
T
Remove the aroma preservation cover.
T
Remove any dirt or foreign objects from inside the bean
container.
T
Fill the bean container with coffee beans and close the aroma
preservation cover.
When you use the machine for the first time, you must set the water
hardness. If you know the hardness of your water, go straight to the
next section. If you do not know the water hardness, you can find
this out first:
T
Hold the test strip under flowing water for one second. Shake
off the water.
T
Wait for about 1minute.
T
You will then be able to read the degree of water hardness from
the discoloration of the Aquadur® test strip and the description
on the packaging.

that you can prepare.
Your J8 creates fine, creamy, feather-light milk foam with a perfect
consistency. The most important requirement for frothing milk is
a milk temperature of 39–46 °F (4–8 °C). We would therefore
recommend using a milk cooler or a milk container.

E Coffee tastes best served hot. A cold porcelain cup cools the
beverage – and impairs the taste. We therefore recommend
prewarming the cups. You can purchase a JURA cup warmer
from your specialized dealer.
Touch ‘Z Z Z Z’ to call up the Specialty Selection and activate the
desired preselection for your next product:
Specialty Selection Meaning
‘S’ – ‘Sweet milk foam’

To ensure that the professional fine foam frother always works
properly, you must clean it daily when you have been preparing milk
(see chapter 7 ‘Maintenance – Cleaning the milk system’).

The preset amount of milk foam flows into the glass.
E There is a short interval while the hot milk separates from
the milk foam. This allows the typical layers of a latte
macchiato to form.
The preset amount of water for espresso flows into the glass.
E 8 minutes after preparation, the milk system is
automatically rinsed. Therefore always place a receptacle
under the professional fine foam frother after preparing milk.
To ensure that the professional fine foam frother always works
properly, you must clean it daily when you have been preparing milk
(see chapter 7 ‘Maintenance – Cleaning the milk system’).
Your J8 prepares hot milk and milk foam. To do this, turn the setting
wheel of the professional fine foam frother to the ‘Milk Foam’ or
‘Milk’ position.
E 8 minutes after preparation, the milk system is
automatically rinsed. Therefore always place a receptacle
under the professional fine foam frother after preparing milk.
For the americano and lungo, the J8 blends the coffee with hot water
using a special preparation method. This results in a full-bodied
specialty coffee which is particularly easy to digest. You can change
the amount of this additional water (see chapter 4 ‘Preparation –
Adjusting the product settings’).

‘Doppio’ is Italian for ‘double’. When you select Espresso doppio,
two espressi are prepared one after the other. The result is an extra
full-bodied and aromatic specialty coffee.
You can choose to use a second coffee variety, for example
decaffeinated coffee, with the filter funnel for ground coffee.
U
Never add more than two level measuring spoons of ground
coffee.
U
Use ground coffee which is not ground too finely. Very fine
coffee can block up the system so that the coffee only comes
out in drips.
U
If you did not fill the machine with a sufficient amount of
ground coffee, ‘Not enough ground coffee’ is displayed and the
J8 stops the operation.
U
The desired specialty coffee must be prepared within approxi-
mately one minute after filling with the ground coffee.
Otherwise the J8 stops the operation and is once more ready
for use.
Example:Proceed as follows to prepare an espresso using ground
coffee.
T
Place an espresso cup under the coffee spout.
