Great instructional video. I just followed his instructions while cleaning and replacing the burrs on my 10 year old Mazzer Mini Timer grinder. However he's wrong when he said it's not necessary to remove and clean the burr located in the top. Since I had to replace both burrs, I removed the old burrs in the top and bottom. The coffee gunk underneath the top burr was twice as much as in the lower burr. Don't worry about his concern that removing the top burr was tricky and you could strip the screws. It was actually easier to remove the top burr then the bottom.

Bill Dalton yeah I guess because that one doesn't spin it's not shaking any grind off?

Though this post is a bit old, hope to enlighten some coffee lovers and help keep their gear clean. In the beginning Brandon says how he dislikes a brown hue in the hopper do to coffee oils, though this is part of it, the fact is if your hopper a older (1-1/2 -2 year old grinder) yellowing of the hopper is normal. This has to do with a chemical used in the manufacturing of the hopper for fire retardant, strength, and molding called Bromine, or the loss of. The loss of bromine doesn't mean that the plastic is recoverable. Though they look a bit rough. Cleaning does help, but if you have cleaned and cleaned with no results it's not coffee oil. But you can fix it. You can use diluted H2O2 (Hydrogen peroxide) 5 to 7 % with water! Seal the bottom with plastic rubber bands or what works with you. Pre mix and fill, then leave outside for 8hrs (that's right) UV reacts with the H2O2 and bromine to remove the ugly hue! bromine is brownish red in production then they use UV to remove hue!

Thank you for this video. I hope to have my Super Jolly soon! Thank you for all that you do and for your services.

[@mark5594]

I'd really appreciate if you could show the burr carrier removal process too. I know it involves using long screws to force the carrier up off the drive shaft but its very difficult to do and I'd love to see it done by a professional! Thanks, great video :)

[@SeattleCoffeeGear]

You're welcome! Hope this will help you keep it in tip-top condition! :) - Kat

[@anelejoya470]

thaks man alot...best way of cleaning the grinder machine i like complement is always there

[@Mr1977Kelvin]

Thanks fot this will be cleaning the grinder I have on long term loan tonight all being well

[@kayelle9463]

newbie question-- so... we don't wash anything? just brush & vacuum it out?

[@SeattleCoffeeGear]

I'll ask Brandon to see if he's game; some things are too involved for us to do on KZbin due to liability issues, though. - Kat

[@5hanesBoard]

Thanks for the video. I'm in the UK and am missing the set-screw. Do you guys know where I can get one as I don't see it listed as a spare part? Thanks

[@mydc2200]

I broke my rancilio rocky thread when i was trying to loosen the upper part

[@MrBRREEETTTT]

Hey, our machine isn’t grinder fine espresso. How do we fix that?

[@rebekahclevenger3484]

You said u might need to grease it, what would you use to do that?

[@westrunningbrook]

Gail and Co., can I ask for a lil recommendation? I accidentally "over-cleaned" my top burr carrier and collar for my SJ while removing a block in the spinning lower carrier, and now...my adjustment collar is stuck half-way on. (Already broke the adjustment rod trying to turn too hard, and bent several M5 bolts.) Any ideas on how you might get a stuck collar off? And what might I use for grease in there? Love you guys and gals! Would buy one of your refurbed Rockets if I could afford it...

[@SeattleCoffeeGear]

It sounds like you may have cross threaded you burr carrier. If that is the case it's not recommended to do that your self and we would recommend finding a location to have your grinder repaired at.

[@IsaacOLEG]

​@@SeattleCoffeeGear that is why any or most, of the threads, are first positionned at the start of the thread by turning the part on reverse direction until the start is heard and felt

[@TriggaWarning]

@@IsaacOLEG Hey Isaac, since you provided really professional insight can you explain a little more detailed how you would screw the collar back on? So you would lightly push down and spin in the reverse direction until you hear and feel a slight click. Would that be appropriate to find the start of the threads?

[@sumsheekirken1549]

There are a few things that I am surprised that were not addressed in the video: 1) The internal AND external threads of the grind-adjustment collar should have been brushed out (easy) to make easier the threading/rotation. He put it back together with a good amount of residue in the threads. 2) The clear plastic insert in the grounds-hopper gets a lot of oily crap on it AND between it and the metal grounds-hopper housing. It never stays as clean as looks this unit. 3) The grounds-chute from the grinder blades to the grounds hopper really SHOULD have a proper-size bottle brush run through it; a lot of chunks and powder builds up in there very quickly. Poking a medium-size screwdriver into the top of the opening does NOT cut it! 4) The three springs and their sockets in which they rest should be cleaned out...yucky!

[@atticustay1]

You should probably turn the grinder off before opening up the burrs

[@lastgoodbye5888]

Guys, just wondering if you can help. Just recently bought a super jolly and after grinding for about a week, 2-3 cups a day. It started grinding less, like 20-30 secs for a single. And i didnt change any settings after when i first set it up. I went through all the steps you guys did and nothing changed. The burrs are definitely grinding but the coffee seems to be stuck somewhere. It seems is jammed in the shute...? Any advices??

[@SeattleCoffeeGear]

Hello Last Goodbye, Likely your grind is just a touch too fine and so by going a little bit coarser, you might not see the clogging that you are currently getting. Or, if you are using an oily bean, to achieve the right timing, you may need the same grind setting, but just need to clean it frequently. Essentially, the oils are building up on the burrs, so this is probably why you are noticing a change and the beginning of what seems to be a clog. A clog can develop quickly (way too fine for the blend of coffee) or slowly (just a little too fine), so it’s about finding the ideal setting for the timing, and of course keeping maintenance in mind. Sounds like at this point it may be clogged, so you may need to take the burrs apart and clean them, and clean out the clogged grounds. Making sure it’s all cleaned, then probably setting it just a touch coarser will take care of the recurring issue, but you will still need to occasionally do maintenance. I hope this helps! ~Miranda

[@ferdialpagu]

Thank you :)

[@IsaacOLEG]

I like the demo but burrs orientation must be preserved I think. a simple dot wit a non permanent marker so you put it back on the same position Thank you, not critical but it is a standard process in mechanical dismounting to use alignment marks for mounting back.

[@SeattleCoffeeGear]

Hey Isaac, while that may be true for many mechanisms, it actually doesn't matter if the orientation is preserved on a coffee grinder. You do need to ensure the top burr goes up top and the bottom burr goes on the bottom, but their orientation is important for this type of grinder. Thanks!

[@IsaacOLEG]

@@SeattleCoffeeGear indeed that was just a general purpose idea. I did work a bit to obtain perfect parallel fitting on a MDF Gaggia, but the top burr is installed in a threaded part so it is sensitive to the threads inclination. Before regulation I had to be on number 1 ,almost touching, once aligned matching I was on 5 .. U just did get a Mazzer SJ and noticed the different fitting for the upper burr. Should be less sensitive. Anyway the bar who sold it to me had it regulated regularly dose and grind,then they do not change anything. (But it was a billiard,not a coffee bar )

[@noir4hire]

PART - 2 From comment below!!! plz read in full! Warning: (You don't want to have H2O2 (Hydrogen peroxide) touch aluminum or other metals while in UV light!!) IT CAN EAT THROUGH aluminum, and discolor stainless steel! So REMOVE ALL METAL PARTS! And Keep AWAY FROM YOUR BEAUTIFUL GRINDER/AND MACHINES! You can use flour, cornstarch, xanthan gum, guar gum, , potato starch or food thickeners to create a paste. You can use a indoor UV light (just keep far enough so it doesn't get hot.. For obvious reasons!)

[@noir4hire]

Oh, also clean thoroughly!!! With water 2-3 times! If you want to be sure you have all the hydrogen peroxide out, wipe your finger around the hopper and taste!, you'll know if there's any residue left!! The percentage left if any will be so low it'll be harmless.

[@soyboyhan2780]

Brandon is so dang cute!

[@PatriziaMuraRice]

the movement of the camera make me to want to vomit.

[@charwin_mark]

pyou should have focus on the grinder not on his face!

[@ralph4840]

OMG! When I see this guy abuse a Mazzer...

[@unlokia]

I hope that vacuum cleaner is clean :-/

Be great if that annoying female voice didn't over ride the main dialogue

[@SpencerDonahue]

Its really unprofessional to waste that much coffee. Muttering under your breath that you realize that its a waste does nothing to diminish the fact that its a huge waste. Maybe plan the videos out a little better next time.

[@SeattleCoffeeGear]

Nobody likes to waste beans, but we needed to clean out the grinder in order to disassemble it and continue with the video. Some people will probably have to do this in their own shop as well. Honestly, the amount of beans that Brandon sucked out with the shop vac was maybe a portafilter's worth of coffee. Not too much! :-) - Sarah

[@SpencerDonahue]

I understand, I've been working in cafes for nearly ten years and Im about to open my own shop this month. I am intimately familiar with the cost of premium coffee and there is no volume of coffee that is disposable unless it somehow gets contaminated. It takes about ten seconds to scoop out most of the beans and then maybe two seconds of grinding to clear the burrs. Considering that the craft roasters that many of us are supplying from are working directly with individual farms for some of their coffee supply it also feels incredibly insulting and wasteful to throw away a product that has been laboured over so heavily and cost so much to get here. Taking into account the fact that petroleum is inherently burned for each bean to make it here then its really a no brainer to save as much as possible. Perhaps Im imposing too much of my own standards here, but I would've expected more from you guys since you have so many videos that people seek out specifically for information.

[@TriggaWarning]

@@SpencerDonahue Thank you Karen.
