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.

PrecisoTM Manual
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.
11
PrecisoTM Manual
Adjustable Self Timer
The Preciso™ is equipped with a 60 second
timerswitch.Eachsegmentaroundthetimer
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 counterclockwise
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-brewing basket. Remove
the grounds bin and position the espresso-
basket inside the grinder directly below the
12
PrecisoTM Manual
pulse button (see photo). Push and hold the pulse button to grind. Grinding will
stop when the button is released.
Note:
It is important that the espresso basket is held below the discharge chute so
the coffee powder can fall freely into the basket. Holding the basket up tight to
the discharge chute will cause coffee to back up and jam your grinder.
PortaHolder™ Installation
Insert the PortaHolder™ into the grinder. Then insert your portalter into the
PortaHolder™ by tipping the basket down so the lip of the portalter 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 portalter basket 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 PortaHolder™. 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 portalter. If you overll the lter, coffee will
back up and jam your grinder.

CARE and CLEANING
Removing the Bean Hopper
Remove all beans from the hopper then press the front mounted pulse button
to run any remaining beans through
the grinder. Remove the plug from the
power outlet. Remove the hopper by
rotating it counterclockwise until it
stops, and then lift the bean hopper off
of the grinder housing.
Removing the Ring Burr
Pull the silicone seal off the top of the
Ring Burr. Remove the ring burr by
liftingitstraightup outofthegrinderby

ring is turned fully counterclockwise.
14
PrecisoTM Manual
Cleaning the Grounds Bin, Hopper and Burrs
Wash the grounds bin, hopper, and the hopper lid in warm soapy water, then
rinse and dry.
If the grinder is used daily, the burrs should be cleaned at least every few months
using tablets (see below for Automatic Cleaning) or with a stiff brush. Proper
cleaning enables the burrs to achieve the most consistent grind possible.
Cleaning also removes some coffee oils, which will stale and degrade the avor
of the ground coffee.
Caution
Do not put the bean hopper, hopper lid,
ground coffee bin, or PortaHolder in the
dishwasher. Hand wash only. Do not
immerse the grinder housing in water.
Do NOT wash the burrs with water.
Replacing the Ring
Burr
Ensure that the black adjustment ring
is rotated counterclockwise as far as it will go. Replace the burr by lining up the
Ring Burr Allignment Tabs
