PrecisoTM Manual
Thank you for purchasing the Preciso™ Conical Burr Coffee Grinder. With the
Preciso™, it’s now easier than ever to make professional quality coffee.
Below are detailed descriptions of the features that make the Preciso™ stand
out from other grinders in its class.
Precision Conical Burrs
Manufactured in Europe, the Preciso’s™ 40 mm conical burrs grind coffee at 1.5
to 2.4 g/sec. depending on the setting. But what really sets the Preciso™ burrs
apart is that these burrs can do a very uniform grind, with a distinct lack of nes
across its grinding range. The Preciso™ burrs are exceptional for espresso, drip,
manual brewing methods and Press Pot. These conical burrs are durable and
will remain sharp for many years. The burrs have a precision mounting system
to ensure a stable platform for accurate grinding.

Grind Adjustment
The range of grind and accuracy of settings is truly impressive. The Preciso™
has 40 distinct Macro settings to enable grinding from Espresso to French
press, with the simple turn of the hopper.
In addition, the Preciso™ has a secondary Micro adjust lever, which further
divides each of the 40 Macro positions into 11 distinct steps. These steps (10
microns each) enable you to precisely dial in the grind for the perfect shot. The
Preciso’s grind range is 200 to 1170 microns.
Efcient Motor
The Preciso™ houses a powerful DC motor that produces more than four times
the output with twice the efciency 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 overheating and automatically resets once the motor
cools.

OPERATION
Before Using Your Grinder
Prior to using your Preciso™ grinder for the rst time you should wash the bean
hopper and ground coffee bin in warm soapy water. See the section on Care
and Cleaning for instruction on how to remove and reinstall these parts. There
may be some rust on the burrs when you receive your grinder. 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
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
Set the Micro adjustment
lever to the middle of the
scale.
Slowly rotate the bean
hopper clockwise or
counter clockwise to align
the indicator on the bean
hopper with the desired
number setting on the
grind scale. Select the
correct grind for the brew process you are using.
Grind a small amount of coffee. Check the particle size. If the particle size is
close to what you desire, 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 (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, brewing style and your favorite beans.
