Conical Burr Coffee Grinder
Operations Manual
The nest in conical burr coffee grinders
1
Thank you for purchasing the Maestro Conical Burr Coffee
Grinder. Below are detailed descriptions of the features that
make the Maestro stand out from other grinders in its class.
Precise, conical burrs:
The slow rotating conical burrs of the Maestro Plus preserve
the aroma and avor of the freshly ground beans. Forty steps of
adjustment provide the ne tuning needed for Espresso, Drip, and
French Press Coffee.
Innovative burr calibration system:
The range of grind and the accuracy of the settings is truly im-
pressive. The Maestro Plus has 40 distinct settings of grind from
Espresso to French Press. An innovative calibration system al-
lows all the manufacturing tolerances of the grinder to be elimi-
nated, resulting in identical, accurate performance from each
grinder. Furthermore the Maestro Plus ring burr is supported
on three points, providing a stable platform for a more accurate
grind.
Efcient motor:
The Maestro uses a 240 watt DC motor. The motor spins at less
than one-third the speed of the AC motors used in most home
grinders, making it much quieter and lower in pitch. In addition,
it possesses a thermal safety device that protects the motor from
overheating and automatically resets once the motor cools.

Initial Operation:
Place the Maestro Grinder on a level surface. Insert the plug into a
120V AC outlet. 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 pro-
cess you are using. 40 grind set-
tings 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.
Setting Type Coffee Grind Average grind
size in microns
1 to 10 Espresso Fine 351 to 495
15 to 28 Drip Medium 701 to 1168
34 to 40 French Press Course 1651 to 1918

Switch Operation
The Maestro is equipped with a specially
designed On/Off switch. 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 determine the amount of time it takes to grind the
quantity of coffee you need.
Grinding into an espresso-basket.
Remove the grounds bin and position the
espresso-basket inside the grinder directly
below the discharge chute. Turn the switch on
until you have the desired quantity of coffee.
Note: It is important that the
espresso basket is held below
the discharge chute so the coffee
powder can free fall into the basket.
Holding the basket 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
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
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, the center cone burr and in the adjustment
area. Vacuum or blow out the residual coffee.
Wash the silicone seal in warm soapy water and
dry.
Replacing the Ring Burr :
Replace the ring burr by lining up the red tab on
the ring burr with the red arrow on the adjustment
ring, if it is not aligned rotate the adjustment ring
fully counter clockwise. Wiggle and push down
rmly on the ring burr to ensure that it seats prop-
erly.
Replacing the Silicone Seal:
After replacing the ring 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.
