I have a sm 90/a grinder that has been in light use for several years.

I need to give it a thorough clean.

Can someone please tell me how to remove the hopper?

Any additional information about cleaning this machine would be great.

Thanks in advance

there is a screw in the grind adjusting wheel (if it's the new style sm90 with black adjusting wheel) also look inside the hopper to see if it has holes where this screw fits.
it also has an o-ring which may drag
worse come to worse take the whole thing out (hopper and adjusting ring with top burr) and look how the hopper may be held.
I have one question for you: I just got an sm95 new style. I flip the on switch and there is a delay 1-2sec when nothing happens, then the grinder starts to spin. Is this normal? All my other electrical appliances power right up when I flip the switch.
Thanks you and good luck

Thanks for your help.

Yes, that screw on the adjusting wheel is a grub-screw that releases the hopper.
The adjusting wheel can then be removed by unscrewing it (reverse thread) from the main unit. This reveals the burrs.

My grinder is now lovely and clean and back in action.

My unit also has a second or so delay after switching on, so this is perectly normal on your machine too.

Thanks again.
