Trina you might be better off to contact Hobart or an authorised Hobart service agent about this. The lack of answers probably indicates resident hobart experts are absent.

You may be correct about a loose spring. Check this:

Carefully lay the mixer on its back side to access the bottom of the mixer. Remove the cover screen covering the opening in the bottom of the mixer. Using an extension and appropriate socket, be sure the nut of the bowl lift rod is snug, slightly compressing the spring of the bowl lift rod.

240v 12qt mixer... that's pretty unusual.

You'll have to register on this site, but you'll probably find what you're looking for here.

you need to remove splash shield, tilt mixer back,with a long screwdriver adj. the set screwclockwise to decrease clearance for beater to bowl clearance,always use b beater when making adj. clearance should be .054" to .115".also make sure there are no deformities in btm of bowl which can cause you problems.dont forget to vote

Assuming the unit is 120v, single phase, my money is on a bad electronic start switch (not to be confused with the on/off switch) It's not visible without some disassembly. Usually, it is located at the rear of the motor cavity. Take note of all the info on your model data plate then go here to obtain a parts breakdown on your particular mixer. http://www.hobartservice.com/Parts/

I'd suggest replacing the capacitor as well.

You need to take the old grease out and replace it with new and then replace the oil seal
by the way it is messsssssy

There is a website called onesharpstore.com that specializes in food processing appliance parts. I saw the hobart model 1812 listed there just today (03/07/09). They even have a number you can call direct. 772-770-4383.

If the mixers are older the dive key shaft,spring or key are broken,if they are newer the key is sheared.Also check the nuts near the beater shaft and make sure there not too tight.

I'd advise that you contact your local Hobart Service Branch for guidance on that question. Please visit the service website at www.hobartservice.com and click on 'Locate an Office" - you'll be able to locate the closest Service Branch to you for advice. Hobart does also sell replacement parts to end users direct as well - through the local Service Branch.
