Maintenance
10.1. General warnings
Before performing any type of maintenance work, the following
indications should be taken into consideration:
• Always turn off the machine using the On-Off switch (14).
• Disconnect the machine from the power supply.
In the event of a breakdown or malfunction, turn the machine off.
Do not try to repair it or intervene directly. Please call your local
technical service.
NOTE: Failure to respect this warning could endanger the safety
of both the machine and user.
10.2. Regular maintenance
To guarantee the efficiency and correct operation of the grinder,
it is essential to follow manufacturer instructions and ensure that
all maintenance work is carried out by qualified staff. Regular,
programmed inspections are recommended of the parts subject
to wear and tear. Systematically check the usage level of the burrs.
The perfect condition of the burrs guarantees an even grind of
the coffee and optimum quality of the product served. It also
reduces electrical consumption and the risk of the motor and
burrs overheating.
NOTE: Based on extensive experience and a medium-hard
coffee blend, we recommend replacing the burrs after grinding
300 Kg/660 Lb of coffee with the K-6 & K-8 models and 1500
Kg/3300 Lb with the conical models.
10.3. Grinding group maintenance
For grinding group maintenance, follow these instructions:
Turn off the machine using the On-Off switch (14). Disconnect
the machine from the power supply. Loosen the setting roller (5),
as shown in Fig. 2, and remove the hopper (2) from the grind
regulator (6).
Release the 3 screws on the grind regulator (6) using an Allen key
as shown in Fig. 10.
Turn the grind regulator (6) clockwise, until it lifts off. Using a small
brush or vacuum, clean the inside of the grinding chamber. Check
the condition of the burrs and change them, if necessary. If not,
