I am looking for a place to download a manual of a Hobart 4812 meat grinder.

Your'e good to go...Tip...keep the meat in a freezer for 30 minutes before grinding it. Apply olive oil in the interior parts of the unit to reduce the friction.

Reset Malfunction is 6 Blinks.

You don't mention what model number, but you might try this page. It has several meat grinder instructions booklets you can download.

The oil seal is the resistance you feel. take a soft mallet or hammer with a soft drift and gently but firmly tap the stub shaft and it will drive out the oil seal in the hopper direction.The lower skirt of the tapered bearing is what contacts the seal so go slow.
Worked for me.

On the 4346 mixer/grinder the clutch can't be adjusted. It is a Moorse clutch and will need to be replaced. If you ate handy buy the rebuild kit for the bottom end from Hobart. It's not cheap but once it's done it will last for years. Hope this helps, Food luck

Yes A-200 are number 12 I would find a hobart grinder they will have a big H in the casting on the neck get one with a stainless pan and stomper to push product down the throat. If you wait on Ebay and put it on your watch list they do come along. look for no rust. Make sure it has the big H in the casting. the other after market ones seem to not last long like the metal wears on the worm and hub to fast. also you always know where to get a piece if you need it if its a Hobart. not so with the forign jobs.
