INTRODUCTION
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 fines 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.
Efficient Motor
The Preciso™ houses a powerful DC motor that produces more than four times the output with twice the efficiency 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 first 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 “fine tune” your grind size (A is finer, K is coarser). If the particle size needs a big change, then adjust the Macro adjustment to a new position, then fine 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.

Adjustable Self Timer
The Preciso™ 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.
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 find 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
11
Preciso

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 portafilter into the
PortaHolder™ by tipping the basket down so the lip of the portafilter 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 fingers that extend from the PortaHolder™. If the portafilter basket is not horizontal in the holder, remove the screw and move the bracket higher or lower in order to level the portafilter basket.
To use, insert your porta filter 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 overfill the portafilter. If you overfill the filter, 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 lifting it straight up out of the grinder by the lifting tabs. If the burr does not lift out, ensure that the grind adjustment ring is turned fully counterclockwise.

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 flavor 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.
Ring Burr Allignment Tabs
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
Preciso
TM
Manual

red tab on the burr with the rectangular cutout on the black adjustment ring.
Wiggle and push down firmly 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.
Replacing the Bean Hopper
To replace the bean hopper, line up the two small tabs on the base of the hopper with their respective slots in the top of the grinder housing and insert the hopper into the grinder. Once the hopper is in place, rotate it clockwise.
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 portafilter are allowed to overfill and ground coffee gets backed up into the grounds chute and grinding chamber.
It can also happen with the buildup of coffee powder over time.
Go to the Troubleshooting section on Baratza.com for help unclogging your grinder.

Manual
Automatic Cleaning
A thorough, fast, and easy cleaning can be accomplished using Full Circle
TM biodegradable grinder cleaning tablets.
Full Circle tablets are designed to dislodge coffee particles and absorb and remove odors and coffee oil residue.
Remove all beans from the hopper and run the grinder to remove any beans inside. Place the recommended amount of Grindz into the empty grinder hopper.
Adjust the grind setting to 30, place insert the grounds bin and use the pulse button to run the grinder. Grind all of the tablets into the bin. Once complete, we recommend grinding approximately
30g coffee to remove any tablet residue.
Discard the ground tablets/coffee. For information on Full Circle cleaning tablets, go to www.urnex.com.
