Initial Operation
Place the Maestro Plus 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 Grind Control
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. 40 grind settings are
available. The settings shown in
the table below can be used as a
general guideline. 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.
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 bean
as it can damage the burrs.
Setting Type of Coffee Grind
1 to 14 Espresso Fine
16 to 28 Filter / Drip Medium
29 to 40 Press Coarse

6
Adjustable Self Timer
The Maestro Plus is equipped with a 60 second
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 counterclockwise until the grinder switches
off. Manual Switch Operation
You may rotate the switch clockwise or counter
clockwise from any position without damaging it.
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 Maestro Plus 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 (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 bas-
ket up tight to the discharge chute will
cause coffee to 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 counter-
clockwise 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 coffee bin in the dishwasher. Hand wash
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
can 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. If the burr does
not lift out, ensure that the grind adjustment tab
is turned fully counterclockwise.

8
Cleaning the Ring Burr
Use the bristle brush (included with your grinder)
to remove any loose coffee residue on the ring
burr and the center cone burr mounted within the
motor housing. Wash the silicone seal in warm
soapy water and dry.
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 red tab on the burr with the
rectangular cutout on the black adjustment ring.
Wiggle and push down rmly on the ring burr to
ensure that it seats properly.
After replacing the burr, replace the silicone seal
by lining up the two slots in the silicone seal with
the small tabs on the top of the ring burr and slide
the seal onto the ring burr.

9
Replacing the Bean Hopper
To replace the bean hopper, line up the two tabs
on the base of the hopper (with the small tab on
the right side) with their respective slots in the
top of the grinder housing and insert the hop-
per into the grinder. Once the hopper is in place
rotate it clockwise to your desired grind setting.
Clearing a Clogged Grinder
If your grinder is not dispensing coffee normally, it could be clogged
with coffee powder. This can happen if the grounds bin or portalter are
allowed to overll and ground coffee gets backed up into the grounds
chute and grinding chamber. It can also happen with the build up of cof-
fee powder over time.
To clear the grinder remove any beans that remain
in the bean hopper, then remove the bean hop-
per. Also remove the ring burr and the grounds
bin. Check to see if the grounds chute is clogged
by looking at the exit of the grounds chute which
is located at the top of the recess that holds the
grounds bin (see photo # 1). If clogged, remove
the coffee grounds with a stiff piece of wire such
as a straightened jumbo paper clip and your
cleaning brush.

Cleaning the Paddle Wheel
Looking at the grinder from the top you’ll see the
cone burr in the center and a paddle wheel with
four ns that rotates at the base of the cone burr
(see photo # 2). During grinding these ns push
the ground coffee out of the grinding chamber.
Ground coffee can get tightly packed between the
ns. Use a straightened jumbo paper clip (or simi-
lar) to remove any coffee powder lodged between
the ns. Once all the coffee is removed, make
sure that all four ns are present and reach to the
wall of the grinding chamber. If the paddle wheel is broken or worn, go
to www.baratza.com troubleshooting to see how to purchase and replace
the paddle wheel.
Cleaning the Grinding Chamber Exit Port
Turn the grinder so the back is facing you, then
rotate the black adjustment ring counter clockwise
until it stops. The rectangular cutout on the ring
should now be at the 11 o’clock position (see pho-
to # 3). Directly below the cutout, at the bottom of
the chamber is the exit port leading to the grounds
bin. If the exit port is clogged, clear it with the
jumbo paper clip and brush. Make sure the exit
port and grounds chute are clear all the way to the
exit of the grounds chute. A blast of compressed air can help complete
the cleaning. Once the clog has been cleared, replace the burr, seal,
and hopper. The grinder is now ready for use.

Automatic Cleaning
Note:
The use of Grindz will NOT CLEAR a clogged grinder, this can only
be done by following the steps in “Clearing a Clogged Grinder”.
A thorough, fast, and easy CLEANING can be accomplished using
Grindz™grinder cleaner. Grindz™is a product de-
signed to dislodge coffee particles and absorb and
remove odors and coffee oil residue. Simply place
one packet of Grintz™into the empty grinder hopper.
Adjust grind setting to 20, and operate as if grind-
ing coffee beans until all of the Grindz™has been
ground. Once complete, we recommend passing
about 4 Tbs. of coffee through the grinder to remove
any Grindz™residue. Discard the ground coffee.
For information on Grindz™go to www.urnex.com.
Grindz™can be purchased at www.baratza.com
