Rancilio KRYO 65 OD User Manual page 8

3.2. Periodically or after intense use
Empty the bean hopper, and clean it of oily residues left by the
coffee with a mild soap solution.
Waste materials used for processing or maintenance, if not
biodegradable or pollutant, should be placed in separate
containers and taken to suitable collection centers.
3.3. Burr replacement
KRYO 65 OD has an integrated counter, which informs the user
after the predefined amount of coffee is grinded, that the burrs
have to be replaced.
This alert can be activated by the service technician during the
commissioning. We recommend activating the alarm.
The burr replacement has to be done by a qualified service
technician only.
Please get in contact with your local sales organization.

Check that the machine, the accessories, the supply cable and the
plug are intact, and in the event of damage, inform the retailer
promptly.
The machines have been designed and built for grinding coffee
beans for professional use.
Any other use is to be considered improper and thus dangerous.
6.1. Burr calibration
To be performed during installation and after burr replacement
The grinders are tested with a medium grind setting, and need to
be readjusted. This operation should be carried out with the bean
hopper empty.
Remove the protection lid (Fig. 1b-5), hold down the adjustment
unlock button (Fig. 2-1) and at the same time slowly turn the
adjustment knob (Fig. 2-3) counter-clockwise until the burrs
brush against each other (when they come into contact, the
sound of metallic friction can be heard). Release the button, turn
the numbered ring (Fig. 2-2) so that the starting point 0 is
frontal; move the adjustment knob (Fig. 2-3) in the opposite
direction (clockwise).
7. FIRST START-UP
7.1. Description of commands
Main switch (Fig. 1-9) with two positions; when switched on, the
machine is ready for coffee grinding.
7.2. First startup
KRYO 65 OD has a startup menu to select the personal
preferences of the operator, when switched on for the first time.
Operator has to choose the language, the mode and the way to
activate the grinding. After choosing the preferences, the display
will show a message "Do Calibration". The calibration has to be
done with the procedure shown in the software structure under
Counter/Burrs/Calibration.
This message will be shown after each preparation up to the
time, the calibration has been done.
7.3. Grind setting
The grinders are tested by the manufacturer with a medium grind
setting. The setting depends on the type of coffee used.
- Place a small quantity of coffee beans in the bean hopper
and close the lid;
- Check that the hopper locking slide is open (Fig. 1–4)
- Position the filter holder on the filter holder fork (Fig. 1-8)
and grind coffee;
- Brew some coffee, checking the dispensing time, the
appearance of the coffee and its taste, considering that
excessively course grounds produce light coloured coffee
without a crema, while grounds that are too fine result in
strong, dark coffee without a crema.
- If the coffee does not respond to your desired requirements,
adjust grind fineness by pressing the ring block button (Fig. 2-1)
and turning the regulation knob (Fig. 2-3) counter-clockwise for
a finer grind or clockwise for a coarser grind.
- Repeat the operation until you have obtained the desired
quality of coffee.
Recalibration of the grind is typically only necessary after a change
in coffee. Minor adjustments may be required throughout use to
accommodate for changes in freshness of the beans.
8. DECOMMISSIONING
8.1. Temporary
- Close the hopper and grind the coffee beans remaining between
the burrs.
