Grinding coffee with the H5:

•Turn the grinder to ON (main switch is placed on the back of the grinder above the power cable socket), when

ON the main screen’s HeyCafé logo light should turn on.

•Open the beans lid and introduce the suitable amount of coffee beans into the hopper. Maximum capacity is

250gr. At first grinding it is recommended to introduce small amount of beans first.

Safety Note: the hopper lid must be closed before using the grinder. A safety device is preventing any grinding if

hopper’s lid is open (When lid is open the front screen LEDs are blinking)

•Set the desired grinding coarseness by turning the setting knob according the graphic instructions (Fine –>

right, Coarse –> left). The grinder is factory set to meet Espresso coarseness.

•Select any of the 3 possible grinding modes by touching each of the icons on the main screen. When selected

the icon LED will be lighted. Disable the selection by touching the selected icon or by selecting a different

grinding mode icon.

•In Single and double modes, use the provided crossed head tinny screw driver to set the desired grinding time.

•Place a porta filter handle or any collecting container under the outlet chute and use the demand switch to

operate the grinder (refer to table 5-1 for operational grinding modes)

Adjusting coffee grind

•The grinding blades’ distance was factory pre adjusted to satisfy different common coffee grinds (from super

fine to coarse) corresponding gap distance from 0.05mm to 0.65mm.

•Turning the grinding dial incrementally to the right direction will make the grind finer and turning it to the left

will make the grind coarser.

•Grind a small amount of coffee and test its coarseness with your espresso machine.

•As coffee beans’ qualities and characteristics are changing from time to time it is recommended repeating this

adjustment once in a while.

Fig5.1

Operating intervals:

•The manufacturer is not recommending grinding continuously for a period of time exceeding 60seconds

•The H5 grinder’s duty cycle is 25%(1/4 of the time grinding; 3/4 of the time resting)

•It is a normal occurrence that during a long grinding period the grinding chamber will heat up. In order to

achieve best grinding results, it is recommended to grind coffee in short intervals of a few seconds each.
