4
2 For your safety
Preventing damage To avoid damage to the machine and the mains cable: U Do not
use the J8 and the mains cable near hot surfaces. U Do not allow the mains
cable to rub against sharp edges and ensure that it does not become
trapped. U Never allow the mains cable to loosely hang down. The mains cable
could pose a tripping hazard or
become damaged. U Protect the J8 from weather and direct sunlight. U Only
connect the J8 to a mains voltage corresponding to that stated on the rating
plate. The rating
plate is located on the underside. U Connect the J8 directly to a domestic
power socket. Using multi-socket adapters or extension cords
may cause overheating. U Do not use alkaline or alcohol-based cleaning agents;
only use mild cleaning agents and a soft cloth. U Do not use any coffee beans
treated with additives or caramelised coffee beans. U Only fill the water tank
with fresh, cold, non-carbonated water. U Switch the machine off with the
On/Off button Q if you are going to be absent for a longer period of
time and remove the mains plug from the power socket. U Only use original JURA
maintenance products. Use of products that are not explicitly recommended
by JURA could damage your J8.
Danger of electric shock Water conducts electricity. Do not bring water and
electricity into contact with one another: U Never touch the mains plug with
wet hands. U Do not immerse the J8 and/or mains cable in water. U Do not put
the J8 or any individual parts in the dishwasher. U Before cleaning, switch
the J8 off with the On/Off button Q. Always wipe the J8 with a damp cloth
rather than a wet one, and protect it from prolonged exposure to water splash.
The J8 must not be cleaned with a jet of water. U The J8 is not suitable for
installation on a surface where a jet of water can be used.
Danger of burns, scalding and injury U Do not touch the spouts during
operation. Use the handles provided. U Optionally, your J8 can be remotely
operated using mobile devices. When preparing a product or
initiating a maintenance programme, make sure that other people are not put at
risk for example, through contact with the spouts. U Be careful to ensure
that the fine foam frother is correctly installed and clean, otherwise the
fine foam frother (or parts of it) may come loose.

3 Preparing and using for the first time
3 Preparing and using for the first time
Setting up the machine 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. Filling
the bean container The bean container has an aroma preservation cover. This
will ensure that your coffee beans retain their aroma for longer. CAUTION
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. Determining the water hardness 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 Aquadur® test strip supplied
under running water for one second. Shake off the water. T Wait for about 1
minute. T You will then be able to read the degree of water hardness from the
discolouration of the Aquadur® test strip and the description on
the packaging.
First-time use J WARNING If the machine is operated with a defective mains
cable, there is a danger of potentially fatal electric shock. T Never use a
machine which is damaged or has a defective mains cable. CAUTION Milk,
sparkling mineral water or other liquids can damage the water tank or the
machine. T Only fill the water tank with fresh, cold water.
Precondition: The bean container has been filled. T For machines with a plug-
in mains cable: Connect the mains cable to the machine. T Insert the mains
plug into a power socket. T Press the On/Off button Q to switch the J8 on.

Problem Insufficient foam is produced when the milk is frothed or milk sprays
out of the fine foam frother.
The Coffee Eye’ reports a cup under the coffee spout even though no cup has been placed there. Coffee only comes out in drips when it is being prepared. There is dry ground coffee behind the coffee grounds container.
Fill water tank’ is not displayed although the water tank is empty. Grinder
is making a very loud noise.
Cause/Result The fine foam frother is dirty.
The cup detection sensor behind the coffee spout is dirty.
Action T Clean the fine foam frother (see chapter 7 Maintenance Cleaning the milk system’). T Dismantle and rinse the fine foam frother (see chapter 7
Maintenance Dismantling and rinsing the professional fine foam frother’). T
Clean the sensor with a damp cloth.
The coffee is ground too finely and obstructs the system. The water hardness
may not have been correctly set. The beans used are resulting in an above-
average volume of ground coffee.
There is a lot of limescale in the water tank.
There are foreign objects in the grinder.
T Put the grinder on a coarser setting or use coarser ground coffee. T Perform
descaling (see chapter 7 Maintenance Descaling the machine’). T Reduce the coffee strength or choose a finer grinder setting (see chapter 4
