Basic information about preparing drinks:
UDuring the grinding operation you can change the coffee
strength of single products. To do this, move your finger
across the display or turn the Rotary Switch.
UDuring preparation you can change the preset amounts (e.g.
amount of water or milk foam). To do this, move your finger
across the display or turn the Rotary Switch.
UYou can stop preparation at any time. To do this, press the
‘Cancel’ button or the Rotary Switch.
Coffee tastes best served hot. A cold porcelain cup cools the bever-
age – and impairs the taste. We therefore recommend prewarming
the cups. The full coffee aroma can develop only in prewarmed cups.
You can purchase a JURA cup warmer from your specialised dealer.
You can make permanent settings for all products in programming
mode (see Chapter 4 ‘Permanent settings in programming mode –
Adjusting the product settings’).
The GIGA offers various ways of preparing a speciality coffee, milk or
hot water.
Preparation using the start screen: Simply touch the desired prod-
uct. The following products are displayed as standard on the start
screen:

2 Preparation
Coffee preparation starts. The preset amount of water for
espresso flows into the glass. Preparation stops automati-
cally. Your GIGA is once more ready for use.
E15 minutes after preparation, the milk system is automatically
rinsed (see Chapter 5 ‘Maintenance – Automatic milk system
rinsing’). Therefore always place a receptacle under the dual
spout after preparing milk.
To ensure that the milk system in the dual spout always works prop-
erly, you must clean it daily (see Chapter 5 ‘Maintenance – Cleaning
the milk system’).
For the ‘caffè Barista’ and ‘lungo Barista’, the GIGA blends the coffee
with hot water using a special preparation method. This results in a
full-bodied speciality coffee which is particularly easy to digest. You
can change the amount of this additional water (see Chapter 4 ‘Per-
manent settings in programming mode – Adjusting the product
settings’).
Products with a bypass amount of water setting are marked with a
red speedometer symbol in the start screen and in the product
selector.
EYour JURA service technician can set the machine so that the
red speedometer symbol is not displayed next to these ‘speed
speciality coffees’.
EFor products with a set bypass amount of water, it is not pos-
sible to change the fill volume during the preparation process.
You can choose to use another coffee variety, for example decaffein-
ated coffee, with the filter funnel for ground coffee.
Basic information about ground coffee:
UNever add more than two level measuring spoons of ground
coffee.
UUse 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.

2 Preparation
UIf you did not fill the machine with a sufficient amount of
ground coffee, ‘Not enough ground coffee’ is displayed and
the GIGA stops the operation.
UThe desired speciality coffee must be prepared within approx-
imately one minute after filling with the ground coffee. Oth-
erwise the GIGA stops the operation and is once more ready
for use.
UAll speciality coffees with ground coffee are always prepared
following the same model.
Example:Proceed as follows to prepare one coffee using ground
coffee.
Precondition:The start screen is displayed.
TPlace a cup under the dual spout.
TOpen the cover of the filler funnel for ground coffee.
