I've done this but it's a bit hard. Once you remove the M8 nut holding it down you need to wedge a flat head screw driver under it and pry it off. Give it a nudge or 2 up and down then rotate to bring it up leveled. That's it. It's a friction fit so it's a bit of a pain. Watch you don't bash your knuckles. I do it every time.
PS: Macap users. You may want to take this off from time to time. A lot of coffee grinds end up under this thing and a shop vac can't get to it.. Was gross the last time I did it.
When I first got my K-6 it had seen serious neglected duty in a coffee shop somewhere. There was thick rancid build up on everything. The only way to get it all clean was to disassemble and scrub- I found a green scrubby to be quite effective. So yes there are reasons one might have to remove the lower burr carrier.
Edit to add- what Burner said is true of a lot of grinders, mine is probably due to be pulled again.

Thanks everybody for the info so far. I tried the screwdriver approach (insert the screwdriver through the opening in the aluminum casting where the ground coffee exits, right?) Couldn't get it to budge. Got nervous about applying lopsided force. So I made a "puller" - piece of 1/4 inch plywood with three holes. Plywood goes across the top. 2 inch screws go through the plywood and into the threaded holes for the burr. Nice, controlled, straight up force on the carrier. Still nothing. Maybe I am being too careful, but I sure don't want to break anything. Maybe I didn't get the screwdriver approach right (didn't do anything that even remotely put my knuckles at risk).

Agreed, especially if its been on a long time, it's going to require some force. Maybe more than your plywood will alow for. You did take the center nut off, correct? I'm assuming you did but you didn't actually say and I hate to assume!

Thanks guys for the added info on this thread. I gave one of my M4s a thorough cleaning today. The lower carrier came out with too much difficultey. I took the plastic upper of the doser off first, so I could pry the carrier up through the exit chute. It wasn't nearly as disgusting as I was expecting based on your comments, but it was definitely needed...we'll see how my other M4 looks though!
