Regular Maintenance - Compak K-3 Elite 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.
10.3. Grinding group maintenance
For grinding group maintenance, follow these instructions:
Turn off the machine using the On-Off switch (14 K-3 Elite – 10 K-3 Touch position 0).
Disconnect the machine from the power supply. Loosen the setting roller (5), as shown in
Fig. 1, and remove the hopper (2) from the grind regulator (6).
Release the position indicator cover (7) with a flat-head screwdriver as shown in Fig. 11
and loosen the screw below it with a Phillips screwdriver.

Turn the grind regulator (6) clockwise as in Fig. 12, 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, put the regulator back in place, turning it counter-clockwise
until the burrs touch and replace the position indicator screw and cover (7) as shown in
Fig. 11 &12.
10.4. Accessing the burrs
Follow the instructions in 10.3. in order to remove the grind regulator (6), removing the
position indicator screw and cover (7) as explained in Fig. 11. Once you have removed
the grind regulator, you will see that it is attached to the upper burr holder allowing you to
manipulate the upper and lower burrs as shown in Fig. 13.
After changing the burrs, assemble the upper burr holder by threading it counter-clock-
wise, replace the grind regulator (6) and follow the instructions as shown in Fig 11 & 12.
