Thank you for purchasing the PRECISO Conical Burr Coffee
Grinder. With the PRECISO, it’s now easier than ever to make professional
quality coffee, whether at home, the ofce, or your café.
Below are detailed descriptions of the features that make the PRECISO stand
out from other grinders in its class.
Precise, commercial-quality burrs:
Manufactured in Italy, the PRECISO’S burrs are of the same material and du-
rability as the industry’s highest-quality line of commercial conical burr coffee
grinders. The burrs rotate slower than those of most grinders minimizing the
heat in the beans, to preserve the avor.
Innovative grind adjustment system:
Macro and Micro adjustments are quickly and repeatedly achievable with this
new precise adjustment system. The range of grind and accuracy of the set-
tings are truly impressive. The PRECISO has over 400 distinct settings of grind
from Espresso to French Press. An innovative calibration system allows all the
manufacturing tolerances of the grinder to be eliminated, resulting in identical,
accurate performance of each grinder. Furthermore the PRECISO’S ring burr
is supported on three points, providing a stable platform for a more accurate
grind. Whether in commercial, semi-professional or personal applications,
exact grind is imperative to a high-quality extraction and, therefore, a better cup
of coffee!
Efcient motor:
The PRECISO houses a powerful DC motor that produces more than four times
the output of a standard AC motor found in most grinders in this class. The
motor spins at less than one-third the speed, making it much quieter and lower
in pitch. Extremely well-made, the motor is built to handle long-duty cycles. In
addition, it possesses a thermal safety device that protects the motor from over-
heating and automatically resets once the motor cools.

grinding whole roasted coffee beans).
• Disassemble your grinder only as directed in the care and cleaning
section of this manual. If you cannot remedy a malfunction check

Note:
You may notice some rust on the burrs. This is normal and will disappear
after a small amount of coffee has been ground. To remove the rust and
season the burrs, grind 1/4 pound of coffee and discard.
Initial Operation
See the bottom of the grinder to determine the proper voltage for the
grinder. Place the PRECISO on a level surface and plug into a correct
voltage, AC outlet only. Remove the lid from the hopper by lifting off.
Pour the desired quantity of roasted whole coffee beans into the hopper
up to a maximum of 8 oz. Replace the lid. Ensure the ground coffee bin
is fully inserted.
Setting the Macro and Micro Grind Adjustment
Slowly rotate the bean
hopper clockwise or
counter clockwise to
align the indicator on
the bean hopper with
the desired number
setting on the Macro
grind scale. Select the
correct grind for the
brew process you are
using. (Note: when-
ever moving the Macro
adjustment to the left(ner direction), the grinder should be running.)
Set the Micro adjustment lever to the middle of the scale. Grind a small
amount of coffee. Check the particle size. If the particle size is close to
what you desire, now use the Micro lever to “ne tune” your grind size (A
is ner, K is coarser). If the particle size needs a big change then adjust
the Macro adjustment to a new position then ne tune with the Micro
lever. The full range on the Micro scale is equal to one “click” or position
on the Macro scale. With both the hopper and the micro adjustment,
moving right (counter-clockwise) produces a bigger particle size and left

Setting Type of Coffee Grind
1 to 14 Espresso Fine
16 to 32 Filter / Drip Medium
34 to 40 Press Coarse
(clockwise) produces a smaller particle size. The actual grind size for a
particular setting will vary depending on many factors, including: degree
of roast (light vs. dark), freshness, humidity, type of bean, oil content, etc.
With use, you will determine the setting that is right for your taste, brew-
ing style and your favorite beans.
Note: Partially ground coffee beans may remain between the burrs after
the grinder is turned off, adjusting the grind may be easier when the
grinder is running. Avoid running the grinder at very ne settings without
beans as it can damage the burrs.
Adjustable Self Timer
The PRECISO is equipped with a 60 sec-
ond timer switch. Each segment around the
timer represents about 10 seconds of run
time. The grinder switches off automatically
once the time has elapsed. If you want
to interrupt grinding
before the time has
elapsed, simply turn
the timer switch coun-
terclockwise until the grinder switches off.
The quantity of ground coffee you need depends on
the type of bean, coarseness of the grind, brewing
method and personal taste. With use, you will nd
the most suitable settings for your personal taste.

Front Mounted Pulse Button
For short duration grinding, the PRECISO is
equipped with a front mounted pulse button. It can
be used for grinding directly into an espresso-brew-
ing basket. Remove the grounds bin and position
the espresso-basket inside the grinder directly
below the pulse button or position the espresso
basket in the Portaholder which is included (see
photo). Push and hold the pulse button to grind.
Grinding will stop when the button is released.
PortaHolder™Installation
Insert the PortaHolder™into the grinder. Then in-
sert your porta lter into the PortaHolder™ by tipping
the basket down so the lip of the porta lter slides
under and gets hooked by the hook bracket at the
top rear of the PortaHolder™ while the base of the
basket is supported by the two metal ngers that
extend from the PortaHolder™ If the porta lter bas-
ket is not horizontal in the holder, remove the screw
and move the bracket higher or lower in order to
level the portalter basket.
To use, insert your porta lter into the PortaHold-
er™. Turn the timer to the desired time. The grinder
will run for the time set and stop automatically.
Note:
Use caution not to overll the porta lter. If you overll the lter coffee will
back up and jam your grinder.

Care and Cleaning
Cleaning the Housing and Hoppers
Switch the grinder off and remove the plug
from the power supply. Remove any remaining
beans from the bean hopper (it may be easiest
to tip the grinder over and pour the beans into
a bowl.). Remove the hopper by twisting it in a
counterclockwise direction as far as it will turn,
and then lift the bean hopper from the housing.
Wash the hopper, hopper lid, and ground coffee
bin in warm soapy water, rinse and dry.
Caution
Do not put the bean hopper, hopper lid, or ground cof-
fee bin in the dishwasher. Handwash only.
Do not immerse the grinder housing in water.
Cleaning the Burrs:
If the grinder is used daily, the burrs should be
cleaned every few weeks. Cleaning enables the
burrs to achieve the most consistent grind pos-
sible. Cleaning also removes coffee oils which
will stale and degrade the avor of the ground
coffee. Do not wash the burr.
Remove the Ring Burr
Pull the silicone seal off the top of the ring Burr.
Remove the ring burr by lifting it straight up out
of the grinder by the lifting tabs.
