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 at 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 ( ), ll the Hopper with coffee ( ), and replace the lid on the
hopper ( ) (Fig. 2).
Plug in the grinder, and place the main power switch ( or ) to position I and open
the bean trap ( ) to allow coffee to pass into the grind chamber. In the TOUCH
ADVANCED model, place the main power switch ( ) ON-OFF in position ON and
place the mode switch ( ) on mode MANUAL (M).
In the PUSH / TOUCH models, the power switch I-0-II is situated on the right side
and on the TOUCH ADVANCED the main power switch is situated on the right side
while the MODE switch is on the left hand side

8.2. Grind adjustment system
8.2.1. 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 ner grinder* (Fig. 3).
* It is recommended that the motor be running when adjusting to ner grind setting.
This helps to avoid jamming the burrs, which can occur when coffee beans are in the
grind chamber, and the grind regulator is adjusted towards ne.
8.2.2. Stepped Grind adjustment (optional)
In the stepped adjustment versions, the positions on the grind regulator are limited
by “steps” that are dened by the hole and pin points (Fig. 4).
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. 4) 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
ne. 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. Adjusting the dose of K3 TOUCH / K3 TOUCH ADVANCED
On the K3 TOUCH / K3 TOUCH ADVANCED models, the grind time is pre-set at the
factory to grind 7 grams of coffee in 6-7 seconds.
To adjust the grind time, simply turn the timer knob ( ) found on the front of the
grinder (Fig. 5 and 6). Turning clockwise will increase the grind time, and turning the
knob counter-clockwise decrease the grind time. The numbers on the dial correspond
with motor run time in seconds.

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 ( , and ).
• Unplug the machine from the power source.
• Do not submerge the grinder in water or use power washing devises.
• The appliance is not to be cleaned with a water jet.
10.2. Bean hopper cleaning
In order to properly clean the bean hopper ( ), rst empty out all remaining beans
and fragments.
To remove the hopper, rst close the bean trap ( ), and then loosen the hopper lock
screw ( ) and lift the hopper straight up.
Clean the hopper ( ) with a moist soft cloth or with a small amount of water and
soap to eliminate any oily residue from the beans.
Replace the bean hopper ( ) following the same steps as the removal process, but
in reverse.
10.3. Cleaning the grind chamber
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.
K01070 | v. 09/06/2016 | Ref. quality process 002/03 | ORIGINAL INSTRUCTIONS
15
The steps to follow are:
In order to properly clean the bean hopper ( ), rst empty out all remaining beans
and fragments.
• Close the bean trap on the hopper ( ) and grind out the remaining coffee in the
grind chamber.
• 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 rell with coffee beans.
• Discard the rst 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 qualied service technician.
10.4. Cleaning the outside of the grinder
To clean the exterior of the grinder, rst 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 ( , and ).
• 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 efciency and correct operation of the grinder, it is essential to
follow manufacturer instructions and ensure that all maintenance work is carried
out by qualied staff.
Dull burrs will result in; a lower quality grind, greater heat generation in the coffee
and grinder, increased electrical consumption, and nally 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.
Burr change
K3 TOUCH, K3 PUSH, K3 TOUCH ADVANCED 350 Kg
11.3. Grinding group maintenance
Not following the recommended burr life guidelines can compromise the safety of
the grinder.
These operations should be done by a qualied service tecnician.
K01070 | v. 09/06/2016 | Ref. quality process 002/03 | ORIGINAL INSTRUCTIONS

To perform grind chamber maintenance please observe the following steps:
Turn off the grinder by making sure the main power switch ( , and ) is on
the OFF position. Disconnect the plug from the power source. Loosen the hopper
security screw ( ) using a flat head screw driver as seen in Fig.1 and remove the
hopper ( ) from the grind regulator ( ).
Loosen the screws on the grind regulator ( ) using an Allen key A3 series
following Fig.12.
Rotate the grind regulator clockwise until it is completely unscrewed. Clean the
grind chamber and threads of the housing using a soft cloth and vacuum cleaner until
all of the oils and residue has been removed.
Make sure to put new food grade lubricant on the clean threading of the housing and
upper assembly. Insert the upper burr assembly into the grind chamber, and turn
counter clockwise.
18
ORIGINAL INSTRUCTIONS | Ref. quality process 002/03 |v. 09/06/2016 | K01070
Position the regulator collar ( ) leaving about 45º between the grind point lock
screw ( ) and regulator limit stop (Fig. 14). In that position, tighten the regulator
( ) on the upper burr carrier and with an Allen key A3 series.
This process should be performed with extreme caution, making sure that there
are no coffee particles or debris in the housing threading. Also the placement of the
upper burr assembly should be done with caution, making sure it is perfectly level
and screwed in patiently. Failure to clean, lubricate or properly place the upper burr
assembly prior to screwing in, can result in blockage or locking of grind adjustment
system.
