STEP 4 – ADJUSTING THE GRIND SIZE
• Whensettingthegrindsizeitshouldbefinebutnottoofineorpow-
dery. The grind will effect the rate at which the water flows through the
ground espresso in the filter and therefore the taste of the espresso.
• Ifthegrindistoofine(lookslikepowderandfeelslikeflourwhen
rubbed between fingers), the water will not flow through the ground
espresso even when under pressure. The resulting espresso will be over
extracted, too dark and bitter, with a mottled and uneven crema on top.
• Ifthegrindistoocoarsethewaterwillflowthroughthegroundespressotooquickly.Thiswill
result in an under-extracted espresso lacking in flavor and without the thick crema on the top.
STEP 5 – ADJUSTING THE GRIND AMOUNT
• WhengrindingforaSingleWallFilterusingafinerespressogrind,
you will need to increase the grind amount to ensure the filter is correct-
ly filled.
• Toincreasethegrindamount,turntheGRINDAMOUNTdialbeyond
theDUALWALLsettingtoobtainthecorrectamountofgroundespresso.
Note: You may need to try step 4 and 5 a few times, slightly adjusting
the GRIND SIZE and GRIND AMOUNT dials each time until you reach
your desired combination.
STEP 6 – GRINDING THE BEANS
• Fillthehopperwithfreshcoffeebeans.
• Ensuretheportafilterisinsertedintothegrindingcradle.
• Ensurethe FILTERSIZEbutton reflects thefiltersize inserted in the
portafilter.
• ForAutoStartandStopGrinding-pushtheportafilter in once to
activate the grinding switch, then allow the portafilter to be filled with
fresh ground espresso.
Note: To stop the auto grinding midway through a grinding cycle, push the portafilter in
once,orpresstheFILTERSIZEbutton.
• Formanualgrinding-pushandholdtheportafilterinuntilthedesiredamountofground
espresso has been delivered.
