8. REGULATION
8.1. Grinder set up
Place the hopper ( ) on the grind regulator ( ) and make sure the bean trap ( )
is in the closed position. Lock the hopper ( ) in place using a flat head screw driver
to gently tighten the hopper security screw making it match to the hole at the bean
hopper collar ( ) (Fig. 1).
Remove the hopper lid (
hopper ( ) (Fig. 2).
), fill the hopper with coffee (
), and replace the lid on the

ORIGINAL INSTRUCTIONS | Ref. quality process 002/03 | v. 05/05/2014 | K01068
8.2. Grind adjustment system
8.2.1. Micrometrical system / Parallel micrometrical system
Rotate the grind regulator ( ) until reaching the grind level desired. Rotating the
grind regulator clockwise will result in a courser grind; turning the regulator counter
clockwise will result in a finer grinder* (Fig. 3).
Once you reach the desired grinding point, you can fix the grinding regulation (
using the regulation break ( ) (Fig. 4). Except K3 and K3 ELITE models.
)
*NOTE: Changing grind settings must be done when the grinder is on and burrs are in motion.
Not doing this suposes that the burrs will gunk up and cleaning will be required.
8.2.2. Stepped grind adjustment
In the stepped adjustment versions, the positions on the grind regulator are limited
by “steps” that are defined by the hole and pin points (Fig. 5).
The instructions detailed in section 8.2.1. on adjusting the regulator should be
followed, while at the same time, pulling the brake post ( ) (Fig. 5) up to release the
locking action of the post.

NOTE: If the output is very slow, it could mean that the coffee is being ground too
fine. If the output is very fast, it could mean that the coffee is being ground too
coarse. A perfect espresso grind is found when the grind point gives an infusion of
25 ml of coffee in 25 seconds using 7 grams of ground coffee.
8.3. Regulating the coffee serving
The dispensers are factory adjusted to serve an amount of approximately 7 gr of
ground coffee, but this quantity can be regulated between 6 and 10 gr, as follows:
1. Remove the ground coffee dispenser lid ( ) and turn the dispensing regulation
screw ( ) clockwise to obtain a smaller amount of coffee, and counterclockwise
to obtain a larger amount (Fig. 6).
2. Once the quantity of eachserving has been regulated, replace the ground coffee
dispenserlid ( ).

ORIGINAL INSTRUCTIONS | Ref. quality process 002/03 | v. 05/05/2014 | K01068
9. OPERATION
9.1. Main switch
The main swith (
) has 2 positions of use, ON–OFF
ON: Working
OFF: Not working
9.2. Use
To turn the machine on and off use the ON-OFF switch ( ). The machine will start
to grind the coffee. If the automatic stop option is incorporated, the grinder will stop
grinding when the dispenser reaches the maximum level, and will restart after 8
portions of coffee have been served, grinding again to the maximum level.
If the machine does not incorporate the automatic stop option, we recommend that
you fill the doser 75% of its capacity in order to guarantee consistent dosing.
To serve the coffee servings, place the portafilter on the fork ( ) as far in as possible
so that it is positioned under the ground coffee discharge tube. Pull the dispensing
lever ( ) to obtain one coffee serving (one serving is equal to one cup of coffee), and
release it so it returns to its normal position (Fig. 7).
9.3. Static press
Take the portafilter and place it under the coffee tamper (
pack the coffee (Fig. 7).

9.4. Telescopic press
When using the telescopic coffee press option, place the portafilter
on the fork (
) and push the coffee tamper downwards (Fig. 8).
10. Cleaning
10.1. General cleaning
To ensure that the grinder functions properly, and produces the highest quality grind
possible, the parts that come into contact with coffee should cleaned periodically.
General Cleaning guidelines as follows:
• Always turn the main power switch to the OFF position (
).
• Unplug the machine from the power source.
• Do not submerge the grinder in water or use power washing devises.
10.2. Bean hopper cleaning
It is recommended that the grind chamber be cleaned monthly with a cleaner as
recommended by Compak. This process will eliminate smelly residues from the
coffee remains, which can negatively affect the quality of the brewed coffee.
14
ORIGINAL INSTRUCTIONS | Ref. quality process 002/03 | v. 05/05/2014 | K01068
The steps to follow are:
• In order to properly clean the bean hopper , first empty out all remaining beans
and fragments.
• Close the bean trap on the hopper (
grind chamber.
) and grind out the remaining coffee in the
• Remove any remaining coffee beans from the bean hopper (
).
• Pour the recommended grinder cleaning product into the bean hopper ( ) and
open the bean trap ( ), allowing the cleaning product to pass into the grind
chamber.
• Grind the cleaning product at a medium course grind setting until the recommended
amount is passed through the system and nothing remains in the grind chamber.
• Clean the hopper (
) and refill with coffee beans.
• Discard the first 2-3 doses of coffee to assure that the residual cleaning product
is removed from the grind chamber and set the grind regulator to the desired
setting ( ).
Following these steps will ensure that the grinder is clean and ready for use.
We do not recommend the taking apart of the grind assembly unless changing burrs,
or removing a blockage/obstruction in the grind chamber. Removal of the grind
assembly should be performed by a qualified service technician.
10.3. Cleaning de ground coffee deposit
To clean the ground coffee holder, first empty all the coffee inside it. Remove the
ground coffee dispenser lid ( ) and clean the inside, using a small brush.
10.4. Cleaning the outside of the grinder
To clean the exterior of the grinder, first wipe with a dry soft cloth, and then gently
wipe with a damp soapy cloth.

11. Maintenance
11.1. General warning
Before performing any type of maintenance you should:
• Always turn OFF the main power switch to the off position (
).
• If the grinder is jammed, unplug it from the power source and contact an
authorized service technician.
Not following these warnings can compromise the safety of the grinder as well as
the user.
11.2. General maintenance of the grind chamber
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.
Dull burrs will result in; a lower quality grind, greater heat generation in the coffee
and grinder, increased electrical consumption, and finally it puts additional stress on
the grinder motor.
NOTE: Based on extensive experience and a medium-hard coffee blend, we
recommend replacing the burrs after grinding 350 Kg/770 lb of coffee.
