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 fine settings without bean as it can damage the burrs.

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 find 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-brewing 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 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.

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 possible. Cleaning also removes coffee oils, which can degrade the flavor 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.

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 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 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 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 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 build up of coffee powder over time.

To clear the grinder remove any beans that remain in the bean hopper, then remove the bean hopper. 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

Photo # 2
Looking at the grinder from the top you'll see the cone burr in the center and a paddle wheel with four fins that rotates at the base of the cone burr (see photo # 2). During grinding these fins push the ground coffee out of the grinding chamber. Ground coffee can get tightly packed between the fins. Use a straightened jumbo paper clip (or similar) to remove any coffee powder lodged between the fins. Once all the coffee is removed, make sure that all four fins 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

Photo # 3
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 photo # 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 designed 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 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 information on Grindz^™ go to www.urnex.com.
Grindz^™ can be purchased at www.baratza.com
