Prior to plugging in observe the following safety instructions:

Protect your device with separate pre-fuses (not

included in the scope of delivery) according to

the information provided under point 2 „Technical

Data“

Make sure that the pre-fuse is not overloaded by

other devices (e.g. fan heaters, deep freezers, etc)

Check whether the main voltage and frequency

correspond to the information on the rating plate

underneath the grinder.

Insert the plug into the corresponding grounded outlet.

4.4 Adjustment of the port-a-ﬁlter rests

The grinder is designed so that all different port-a-ﬁlters from various

espresso machines ﬁt into the rest for hands-free grinding operation.

4.4.1 Keep the grinder switched off. Slightly loosen the allen screws

(pos. 13) with the included allen screw driver size 3mm and pull down

he port-a-ﬁlter rest (pos. 12).

4.4.2 Push the port-a-ﬁlter of your espresso machine onto the start/stop

switch between the port-a-ﬁlter mounting (pos. 11) and the rest (pos 12).

Now push up the port-a-ﬁlter rest until the port-a-ﬁlter holds on its own.

Now refasten the screws. The adjustment is correct when the port-a-

ﬁlter stays independently remains in the mounting.

4. Set-up and Initial Adjustments

You have received your grinder in operating condition. Now you only need to

place it in a safe place and connect it to the main power socket. Proceed as

follows:

4.1 Place of Installation

Place the grinder on a level, vibration-free surface.

Never operate the grinder in moist, or even worse, in

wet surroundings!

4.2 Locking in the hoppers

Set the hopper into the bayonet socket. Grab the hopper with both hands and

turn it carefully in clockwise direction, until the bayonet locks in.

Always loosen the grind adjustment brakes and turn

both adjustments to ﬁne (setting 0) when locking in the

hoppers. Turning the grind adjustment ring repeatedly

without loosening the brake could damage the interlock.

Fasten the lock screw for the hopper (pos. 2) to prevent the hoppers from un-

authorized removal.

Page 8

In case the port-a-ﬁlter rests does not ﬁt your espresso

machine’s port-a-ﬁlter, please contact us or your local

dealer. We will be happy to send you a different rest.

4.5 Adjustment of the cleaning alarm

The software of the KED 640 has an integrated cleaning alarm which is activat-

ed at a preset amount of shots taken. This alarm should remind you of cleaning

the grinder regularly in order to increase the discs‘ lifetime.

DITTING recommends: The cleaning limit should be set

to the amount of shots that are ground per week. (For

the set-up of the limit and for resetting the counter after

cleaning see chapter 5.5.9)

5. Operation

Once the grinder is set up and ready to operate a grinding test should be car-

ried out.

5.1 Instructions for the ﬁrst grinding steps

Only use the KED 640 espresso grinder for whole roasted

coffee beans.

Observe the safety instructions under 1.2!

Never exceed the maximum permissible continuous

operating cycle of 4 sec ON, 6 sec OFF (S3 40%). Also do

not exceed the maximum allowable continuous grinding

time of 20 min. Afterwards, allow the grinder to cool

down before the next operation.

5.2 Operating the grinder

5.2.1 Switch on the grinder at the back of the casing (pos. 16).

5.2.2 Open the hopper and pour whole roasted espresso beans into the hopper

Never pour in coffee powder which would result into

immediate blocking of the discs.

5.2.3 Adjust the grinding ﬁneness by pulling the grind adjustment interlock

(pos. 4) and turning the ring (pos. 3) including the hopper to the desired posi-

tion. Note that „0“ is the ﬁnest setting and „10“ is the coarsest. Let go and

re-lock the brake to ﬁx the setting.

Test runs have proved grind adjustments 1 – 4 to be the

most common settings for espresso depending on the or-

igin, roast and blend. This should be taken into account

when adjusting the grinder for the ﬁrst time.

5.2.4 For the ﬁrst test run the grinding time settings are pre-programmed for

single shots to 2.0 sec and for double shots 4.0 sec. For changing these set-

tings please see chapter 5.3.

5.2.5 Choose the single or double pre-select-button according to your

port-a-ﬁlter. The LED shows which button is selected.

5.2.7 Now brew a test portion of espresso using your machine. If the result

is unsatisfactory, alter the adjustment again by varying the grinding time and

grinding ﬁneness until the best coffee results have been achieved.

5.3 Interruption of grinding (break-function)

If the grinding process is interrupted before the set grinding time has expired,

the LED in the active pre-selection button ﬂashes. The grinding process can

be re-started by pushing the port-a-ﬁlter back into the mounting. The missing

quantity is ground. If this is not desired push the pre-selection button and the

entire set grinding quantity or grinding time is available once again.

5.4 Software Menu

The following overview shows the handling of the KED 640´s software.

5.2.6 Push your espresso machine’s port-a-ﬁlter into the port-a-ﬁlter mounting

(pos. 11/12) so that the grinding process starts.

The ﬁrst operation will not result in the desired amount

of espresso because the grinder has to ﬁll up with

ground coffee. The second shot should give the correct

result.
