SURIHVVLRQDOTXDOLW\FRIIHHZKHWKHUDWKRPHWKHRI¿FHRU\RXUFDIp
Below are detailed descriptions of the features that make the PRECISO stand out from other grinders in its class.
Precise, commercial-quality burrs:
Manufactured in Italy, the PRECISO’S burrs are of the same material and du- rability as the industry’s highest-quality line of commercial conical burr coffee grinders. The burrs rotate slower than those of most grinders minimizing the

Innovative grind adjustment system:
Macro and Micro adjustments are quickly and repeatedly achievable with this new precise adjustment system. The range of grind and accuracy of the set- tings are truly impressive. The PRECISO has over 400 distinct settings of grind from Espresso to French Press. An innovative calibration system allows all the manufacturing tolerances of the grinder to be eliminated, resulting in identical, accurate performance of each grinder. Furthermore the PRECISO’S ring burr is supported on three points, providing a stable platform for a more accurate grind. Whether in commercial, semi-professional or personal applications, exact grind is imperative to a high-quality extraction and, therefore, a better cup of coffee!
(I¿FLHQWPRWRU
The PRECISO houses a powerful DC motor that produces more than four times the output 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 over- heating and automatically resets once the motor cools.

Note:
You may notice some rust on the burrs. 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
See the bottom of the grinder to determine the proper voltage for the grinder. 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
Slowly rotate the bean hopper clockwise or counter clockwise to align the indicator on the bean hopper with the desired number setting on the Macro grind scale. Select the correct grind for the brew process you are using. (Note: when- ever moving the Macro

(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, brew- ing style and your favorite beans.

Adjustable Self Timer
The PRECISO is equipped with a 60 sec- ond 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 coun- terclockwise until the grinder switches off.
The quantity of ground coffee you need depends on the type of bean, coarseness of the grind, brewing

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-brew- ing basket. Remove the grounds bin and position the espresso-basket inside the grinder directly below the pulse button or position the espresso basket in the Portaholder which is included (see photo). Push and hold the pulse button to grind.
Grinding will stop when the button is released.

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 cof- fee bin in the dishwasher. Handwash 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

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.

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.
:LJJOHDQGSXVKGRZQ¿UPO\RQWKHULQJEXUUWR 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 hous- ing and insert the hopper 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

Cleaning the Grounds Chute:

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

WR'LUHFWO\EHORZWKHFXWRXWDWWKHERWWRPRI 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

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 designed to dislodge coffee par- ticles 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 grinding 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 informa- tion on Grindz ™ go to www.urnex.com.
Grindz ™ can be purchased at www.baratza.com
