Regular Maintenance - Compak K-6 Bedienungshandbuch

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-6 Silenzio / K-6 Professional Barista / K-8 / K-8 Silenzio / K-10 Conic
models and 1500 Kg/3300 Lb with the K-10 Conic WBC model.
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 regula-
tor (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 va-
cuum, clean the inside of the grinding chamber. Check the condition of the burrs
and change them, if necessary. If not, put the regulator back in place, turning it
counter-clockwise as in Fig. 11 until the burrs touch and replace the 3 screws.
10.4. Accessing the burrs
Follow the instructions in 10.3. in order to remove the grind regulator, removing the
3 screws as explained in Fig. 10. Once this is done, you will have to manually turn the
upper burr holder clockwise to remove it from its housing as in Fig. 12.
After changing the burrs, assemble the upper burr holder by threading it counter-
clockwise, replace the grind regulator (6) and follow the instructions as shown in
Fig. 10 & 11.
