In case the port-a-filter rest does not fit your espres-
so machine’s port-a-filter, please contact us or your
local dealer. We will be happy to send you a differ-
ent rest.
5.4.2 Push the port-a-filter of your espresso machine onto the start/
stop switch between the port-a-filter mounting and the rest.
5.4.4 Now push up the port-a-filter rest until the port-a-filter holds on
its own. Refasten the screws.
6. Operation
Only use the KE640 / KE640 Vario espresso grinder for whole roasted
coffee beans. See chapter 1.3.
Observe the safety instructions under 1.2!
The max. permissible operating cycle for 200-230V and 240V is 4 sec.
ON and 16 sec. OFF, i.e. three double shots per minute. For 115V the
max. permissible operating cycle is 6 sec. ON and 60 sec. OFF. Do not
exceed the maximum allowable continuous grinding time of 20 min.
Afterwards, allow the grinder to cool down before the next operation.
6.1 Handling the grinder
Proper operation necessitates the steps described in the following:
5.3 Electrical installation
Protect your device with separate pre-fuses (not in-
cluded in the scope of delivery) according to the in-
formation provided under Point 2 “Technical data”.
Make sure that the pre-fuse is not overloaded by
other devices (e.g. fan heaters, deep freezers).
Check whether the main voltage and frequency cor-
respond to the information on the rating plate.
Insert the plug into the corresponding grounded outlet.
5.4 Adjustment of the port-a-filter rest
The grinder is designed so that all different port-a-filters from various
espresso machines fit into the rest (pos.14) for hands-free grinding op-
eration.
Proceed as follows for adjusting the port-a-filter rest:
5.4.1 Keep the grinder switched off. Slightly loosen the allen screws
(pos. 15) with the provided allen wrench size 3mm and pull down the
port-a-filter rest (pos. 14).
