I have got myself a second hand Mazzer Super Jolly but it has grinds caked into it from the first day of operation and it has seemingly NEVER been cleaned during its long and hard life as a commercial loan/rental machine.
I expected to be able to find clear step by step guides with good photos somewhere on the internet detailing the operation of deep cleaning the machine, but haven't found anything yet that I would be comfortable diving into as a newbie.
Here are my main questions having taken down the grinding well as far as the bottom assembly:
1. What is the easiest and best way to remove the bottom assembly? I have seen this method mentioned on Home Barista using long bolts being sequentially screwed in to lift the assembly - is it a good method?
2. Is returning this assembly after cleaning a difficult proposition? And do I risk doing damage if I attempt to remove and clean below the bottom assembly?
3. When replacing the grind adjustment ring, how many turns am I supposed to take it before inserting the safety limiting screw? What stops me from accidentally turning the top burr to make CONTACT with the bottom burr?
4. And while I have read that taking the doser apart completely is a risky job due to fragile parts, is there a guide you can point me to which goes through taking SOME of the doser apart (the non-fragile bits) to give this a better clean?
Google has provided me with insufficient information so I'm hoping someone here can point me in the right direction.
I am obviously not the most mechanically minded person but can do a *basic* disassemble and reassemble job if given a decent instruction set and good photos. Thanks
