6. INSTALLATION

Installation must be performed by a qualified technician.
The machine is delivered ready for installation according to the
data on the plate Fig. 3.
Check that the main power supply is compatible with the machine.
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.

7. FIRST START-UP

7.1. Description of commands
KRYO 65/ST
Main switch (Fig. 1-9) with two positions. When switched on, the
machine is on and starts coffee grinding.
KRYO 65/AT
Main switch (Fig. 1-9) has two positions; in position (I), the machine
is on and automatically shuts off when the doser is full enough.
7.2. Grind setting
The manufacturer tests the coffee grinder 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) pushed in)
- Grind a small quantity of coffee:
- Position the filter holder on the filter holder fork (Fig. 1-8),
then pull the dosing lever (Fig. 1a-11) to dispense a dose of
ground 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.
7.3. Adjusting the ground coffee dose
Adjust the dose as followed:
- Turn the knob below the doser (Fig. 1a-12) counter-clockwise
to increase the dose or clockwise to decrease the dose.
- Pull 6 times the lever (Fig. 1a-11) and check the dose each
time. Take care that the dosing star is completely covered
with ground coffee

8. DECOMMISSIONING

8.1. Temporary
- Close the hopper and grind the coffee beans remaining
between the burrs.
- Turn off the main switch and unplug the appliance from the
power source;
- Remove the ground coffee and any coffee beans remaining in
the bean hopper.
- Perform cleaning and maintenance operations;
- Coil up the supply cable and attach it to the machine using
adhesive tape;
- Cover the machine and place it in a dry place, sheltered from
bad weather and to which you have exclusive access.
8.2. Final
In addition to the operations of temporary decommissioning:
- Cut the power cable,
- Pack up the machine using cardboard or similar materials
and hand it over to specialized operators (authorized waste
disposal collectors or dealers in second-hand goods)

9. INFORMATION FOR SERVICE TECHNICIANS

9.1. Replacement of burrs
Although manufactured in tempered steel, the burrs are subject
to wear and tear.
Their lifespan is influenced by the amount of coffee ground, its
hardness and degree of roasting, as well as the quantity and
purity of the coffee beans.
Small stones and various impurities have a marked abrasive
action that significantly reduces the lifespan of the burrs.
When grinding time becomes noticeably longer or the grind
becomes irregular, the burrs should be replaced as follows:
- Pull the hopper locking slide (Fig. 1–4);
- Start the grinder to grind the coffee remaining between the
burrs;
- Once grinding has finished, turn off the machine and unplug
from the power source;
- Empty the bean hopper (Fig. 1–2);
- Remove the regulation knob (Fig. 1–3);
- Turn the upper burr-holder (Fig. 4–1) counter-clockwise until
the head emerges completely;
- Unscrew the screws (Fig. 4–2) and remove the burrs (Fig. 4–3)
from the burr-holder:
- Carefully clean the burr supports, the burr-holder thread and
its housing;
- Position the new burrs in their holders and block them firmly
in place;
- Reassemble the machine, performing the previous steps in
reverse.
- Calibrate the new burrs.
9.2. Calibration of grinder burrs
To be performed after burr replacement
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. 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).
