Hello everyone... looking for a bit of help with the grinder we're using.. it's a Rossi RR558 and only has two buttons, one to automatically grind a single shot and one for a double.

The problem is that the shots it grinds are only 7-8g and 14-16g respectively and not at all conducive to good espresso, which is frustrating as we're using great beans. I assume it's possible to change the settings and increase the weight of the shots but can't figure out how as all i have to work with are the two shot buttons and a digital display which only scrolls '00047532'.


I've searched for manuals online with no success, hoping someone has the same model and can advise me???


Thanks. John.
