8 MAINTENANCE AND CARE Grinder EK-7 Bean Hopper Bean Stop Grinder Grinder outlet Grinder Adjustment Wheel Fixation Screw Periodic maintenance Each month: clean outlet, grinding house and grinding discs. Monthly cleaning of grinder using GRINDZ cleaning tablets (item no. E ). Safety Please read and observe the following service instructions carefully. Non-observance can result in damage to the grinder as well as in healththreatening risks for the user. All installations shall been done by an qualified personnel. Symbols Safety instruction: In case of non-observance, extreme risk of accidents exists. General instruction: In case of non-observance, the device can become damaged or optimum operation not be guaranteed. Safety instructions The grinder is only allowed to be used to grind whole coffee beans. Ground coffee is never allowed to be filled into the input-shaft. Do not carry out any modifications or changes on the grinder. In case for non-observance, the manufacturer shall be liable for resulting damain no case whatsoever. Never put your fingers or objects into the rotating grinding mechanism inside the inputshaft.the grinder must not be operated when turning parts are accessible! Make sure, that the power cannot be turned on when working on the built-in grinder! In order to avoid damages, do not use power tools or cordless electric screwdrivers for any work on the grinder. 8

9 MAINTENANCE AND CARE Grinder EK-7 Monthly maintenance Approximately every month the grinder housing and spout should be inspected for coffee residues and obvious damages. A Fig.1 Fig.2 Proceed as follows: Remove bean container. Remove all coffee residues from the spout and the grinder housing by grinding through all coffee beans and using a vacuum cleaner to remove all residues. Remove the two Phillips screws (A, See fig.1) on the side of grinder housing lid. Carefully detach the grinding housing. Fig.1 Note its position for correct reassembly. Do not alter the adjustment of the grinding discs. Clean the inside of the grinder housing with a soft brush. (See fig.2) When reassembling the grinder housing, again check for the correct position and do not alter the grind adjustment of the discs. Fasten the two Phillips screws. 9

10 MAINTENANCE AND CARE Grinder EK-7 Basic adjustment of the grinding finess The grinder adjustment can be easily reached through the space between the bean hoppers, before adjusting loosen the fixation screw in front of the adjuster wheel to be able to rotate it. To adjust the coarseness for left grinder, rotate the adjuster wheel towards you for coarser grinding. For finer grinding rotate the wheel away from you. To adjust the coarseness for right grinder, rotate the adjuster wheel towards you for finer grinding. For coarser grinding rotate the wheel away from you. Take into consideration that after the adjuster is moved, the effect is not immediate, it takes about 1 coffee cycle for the new coffee grounds to reach the outlet and into the brewer. So to test the new adjustment, observe the second coffee after the change. The finer the grinding, the slower the coffee will come out, and longer time will be needed for the extraction of the espresso and vice versa. CCW for Coarser Grinding CW for Finer Grinding Fig.3 10
