If the grounds are uniform, equal amounts of soluble compounds will be extracted from each. If the grounds vary in size, some will be over-extracted and some will be under-extracted, leading to extremely poor quality. It's not surprising that a precision grind is mandatory for good espresso, which is brewed with near-boiling water under 130-lbs. of pressure. Continued… 21 Coffee grind quality is directly related to the type of grinder used. High speed grinders with small burr sets are usually not able to produce the fineness or consistency required for the best espresso. They also excessively heat the beans while grinding, resulting in lost flavor and aroma. The PRO LINE™ Series Burr Coffee Mill uses a pair of large, commercial- style cutting burrs to grind coffee with precision. Frictional heating is minimized with a gear reduction system that slows burr rotation, and uniformity is enhanced with a helical-gear that transports beans to the burrs at a controlled rate. The result is a superb grind that makes your coffee and espresso the best it can be. 22 PRO LINE™ SERIES PRO LINE™ SERIES CARE AND CLEANING Cleaning the Housing & Hoppers......24 Cutting burrs Cleaning .......................................25 Adjusting for Wear ........................28 Replacing......................................29 Troubleshooting................................30 Care and Cleaning Section Contents CARE AND CLEANING 23 CARE AND CLEANING Cleaning the Motor Housing and Hoppers • Make sure the coffee mill is switched off and unplugged before cleaning. • Do not immerse the motor housing in water. • Never immerse the cutting burrs, burr-shaft assembly, or face-plate assembly in water. Keep them dry at all times. • Do not use abrasive cleansers or scouring pads. Wipe the motor housing and cord with a clean damp cloth. Dry with a soft cloth. Wash the coffee bin, bean hopper, and hopper lid in hot soapy water, then rinse and dry. The bean hopper, hopper lid, and coffee bin can also be washed in the top rack of a dishwasher. 24 Cleaning the Cutting Burrs If the mill is used frequently, the cutting burrs need to be cleaned every few weeks for best performance. Cleaning enables the burrs to achieve the finest, most consistent grinds possible – which is especially important when grinding coffee for espresso. Foreign objects – like pebbles or twigs – sometimes find their way into whole bean coffee. These objects may cause the mill to jam. If this happens, follow the burr-cleaning procedure to remove the foreign material. 1. Make sure the mill is switched off and unplugged. Remove the coffee bin and bean hopper from the mill. 2. Using a flat-head screwdriver, turn the two faceplate screws counterclockwise until the faceplate assembly is free. (The faceplate screws have retaining clips that prevent them from being removed from the faceplate assembly.) CARE AND CLEANING Continued… 25 CARE AND CLEANING 3. Carefully slide the faceplate assembly away from the motor housing. A separate burr-shaft assembly on the inside of the motor housing will usually slide out with the face plate assembly. Place a hand under the burr-shaft assembly to prevent it from falling as the faceplate assembly is removed. If the burr-shaft assembly does not slide out with the face-plate assembly, grasp the center shaft of the burr-shaft assembly and remove it from the housing. Burr-Shaft Assembly Faceplate Assembly 4. Using the burr-cleaning brush, clean the burr mounted on the burr-shaft assembly and the burr mounted within the motor housing. NOTE: Never wash the burrs or burr- shaft assembly in water. Keep them dry at all times. 26 5. After cleaning, tilt the grinder backward so the front of the motor housing faces upward. 6. With the corkscrew-shaped auger shaft facing into the motor housing, insert the burr-shaft assembly into the grinder. Keep the burr-shaft assembly level, so the tip of the auger shaft will line up with the small socket in the motor housing. 7. Once the burr-shaft assembly is in the motor housing, rotate the assembly until it falls into place. When correctly positioned, the burr- shaft assembly cannot be rotated. CARE AND CLEANING Continued… 27 CARE AND CLEANING 8. Place the faceplate assembly onto the motor housing. Make sure the numbers on grind level ring are positioned across the top of the assembly. Using your fingers, tighten the faceplate screws by turning them clockwise. Alternate tightening the screws, keeping them even – do not completely tighten one screw before tightening the other. 9. After the faceplate screws have been finger-tightened, use a flat- head screwdriver to tighten them until snug. 10.Place the grinder upright. It is now ready for use. Adjusting The Cutting Burrs For Wear The cutting burrs are made of high- quality stainless steel for exceptional longevity. After prolonged use, however, the burrs might require adjustment to compensate for wear. If your grinds – especially espresso – are not as fine as they used to be,...
