Before putting into service
Function
The shot sizes, i.e. the grind quantities per reference, are defined by the grinding
time in this grinder.
The user can specify up to five different recipes (grinding times) and also has the
option of controlling the grinding time manually (manual grinding).
The grinding process starts automatically when the portafilter is inserted and stops
automatically after the defined grinding time has elapsed (grinding according to
recipe) or when the portafilter is removed (manual grinding).
The following recipes (grinding times) are preset at the factory:
Single Shot: 2.5 seconds (approx. 7–8 g*)
Double Shot: 4.5 seconds (approx. 14–16 g*)
To adjust the factory setting and define other grinding times for the recipes, proceed
as described in chapter „Setting or changing the recipe/grinding time“.
The grinder has two modes: Pro Mode and Basis Mode. In Pro Mode, the user can
adjust settings (e.g.change the grinding times for each recipe). In Basis Mode, the
user can only use the grinder in the preconfigured state.
To switch from one mode to the other, tap the corresponding symbol or
on the Typo, Recipe selection display on the touchscreen. The user password must be
entered when switching from Basis Mode to Pro Mode.
Check the grinder and scope of delivery
1. Remove the grinder from the packaging.
2. Check that the delivery is complete.
3. Check for damage to the grinder or the individual parts. If this is the case, do not
use the grinder. Contact your dealer (see chapter „Maintenance and service“).
Setting up and connecting the grinder
1. Place the grinder on a level, stable and vibration-free surface.
2. Make sure the grinder is switched off (On/Off switch (6) in position 0) and
connect the grinder to the mains by inserting the mains plug (4) into a properly
installed earthed socket.
3. Insert the drip tray (9) in the corresponding housing recess.
* The amount of grind depends on the type of espresso bean, the selected grind and the mains fre-
quency (see chapter „Technical data“).

Inserting the bean hopper
1. Place the bean hopper (1) on the grinder.
When placing the bean hopper, make sure to place the nose of the bean hopper
in the corresponding recess of the bean hopper intake (2).
2. Push the bean hopper down slightly into the bean hopper intake and turn the
bean hopper clockwise to fix it to the grinder.
If the bean hopper cannot be fixed in place by turning it, it may not be positioned
correctly. In this case, align the bean hopper correctly and then try again to fix it
by turning (see also the chapter „Troubleshooting“).
3. Tighten the securing screws for the bean hopper clockwise.
The grinder switches off automatically when the bean hopper is not in use.
Setting up the portafilter support and spout
Adjust the portafilter support (10) to the size of the portafilter of your espresso
machine as described below.
1. Make sure the grinder is switched off (On/Off switch (6) in position 0).
2. Using a screwdriver, unscrew the two screws (8) for adjusting the portafilter
support (left and right) a few turns anticlockwise.
The portafilter support (10) is lowered as far as it will go.
3. Insert the portafilter in the portafilter intake(12).
4. Push the portafilter support upwards until the portafilter fits exactly between the
portafilter support and the portafilter intake.
If the supplied portafilter support does not fit, contact your dealer (see

Operation
The grinder has a thermal overcurrent circuit breaker that interrupts the
grinder's circuit in the event of an electrical overload. To start the grinder
again, set the On/Off switch (6) to switch position 0 (Off). Then press
the release button (7) on the back of the grinder. You can now switch the
grinder on again by setting the On/Off switch to switch position I and
starting up the grinder (see chapter „Troubleshooting“).
NOTE! Risk of damage!
The operator has no influence on the thermal overcurrent circuit breaker. If the circuit
breaker trips several times, it is essential to consult an authorised service partner, as
the motor winding may be damaged.
NOTE! Danger of overheating!
Exceeding the maximum permissible grinding quantity per day can lead to overheat-
ing of the grinder.
» Do not exceed the maximum grinding quantity per day (see chapter “Technical
data”).
Filling with espresso beans
