Sounds like a bad capacitor or centrifugal switch.
Most bench grinders won't have replaceable centrifugal switch but may have replaceable capacitors.
Look for a cover on the motor that bubbles out - probably 2 screws.

SOURCE: bench grinder, 110/220?? wired up properly

LIKELY the capacitor which is usually in the base is bad.

The capacitor shifts the phase angle in one of the two windings which creates a pseudo rotating field to start rotation.

SOURCE: the coffee grinder on my Magic Comfort Plus is not

Hi Sounds like you have a blockage in you grind passage. Try removing the brew group. Then inside on the roof of the machine where the brew unit was setting there is a drop chute where the coffee is dropped into the brew unit. From the left side of the drop chute pull down and back, and it will drop coffee. This will clear an opening that relieves pressure on the passage. There is a passage inside the drop chute area that goes to the grinder. Vacuum it out. It will be on the right side of the drop chute. Once that is cleared go to the bean hopper. There is a lever under the bean hopper. Push the lever back to the largest number. You can push the lever to a larger number any time, but it has to be grinding to pull to a smaller number. Now replace everything and make your coffee. Once you have made your coffee you can pull back to a number that was higher than the one you had it on, but only when the grinder is running.

SOURCE: Whirlpool stylemaster 4217141 REV A Agitator/spin cycle broken upper agitator spins by hand but tub won't spin

open the lid and get a model #, sound like all you need is agit dogs # 80040. then remove top of the agitator, could be a softener dispenser. under that you will find a plastic cap, pull up with needle nose pliers. under that you will find a 7/16 or 1/2 bolt, remove the bolt and the agitator can be lifted off. the agitator can now be split into to pieces, turn the top half over and the assy with the agit dgs will fall out. simply replace and reassemble and DO NOT OVER TIGHTEN BOLT. just snug it up. should be fine.

Cummins model C-140 Bench Grinder. Can I get an owners manual please?

There is a similar one on eBay, but no free ones. Cummins are known for diesel engines rather than grinders, which means someone else made it and put a Cummins badge on it. Take your pick from any of these.

https://www.google.com/search?q=8%22+Bench+Grinder+manual

They don't need much of a manual anyway, most of the content is on safety. Press switch to turn on and off, one arbor is right hand thread, the other is left hand thread.

I have an older 6" bench grinder. some times it works, thn it wont. It growls and is trying to spin and it does turn the wheels slowly. Does it need oil? How can i get it running freely gain?

A grinder that growls when you start it usually means the bearings are worn out or very dry. You can try a little WD40 spray in the bearing area and if that seems to work use some heavier oil to keep it running. It's good to oil the bearings every so often I find.

How to remove wheel on delta 10' grinder

Unplug it first, if you like your skin.

Use a wrench on the nut, and hang onto the wheel with one bare hand while you turn the nut in the same direction as the wheel normally spins. If you have a lot of difficulty doing that, jam the wheel with a piece of wood.

How do you tighten the nuts when changing the wheels on a 6 inch craftsman bench grinder. Thank you...

Clamp the shaft behind one wheel with 'Channelock' or 'Visegrip' pliers, then tighten both nuts. Check the new wheels for 'off-center' running by spinning them with your hand. They may fit the shaft tight enough that there is no centering adjustment--use a 'wheel dresser' (either a stone type or a multi-wheel type) to true up the wheel so that there is no radial wobble. Hope this helps!

Grinder won't turn on. Switch tests good with ohm meter and jumping. When switch is turned to ON the shaft makes a slight effort to turn, and humms. The shaft is free to spin by hand.

It sounds like the capacitator might be bad or the starter windings. What you can try and BE CAREFUL is turn the switch on and spin the wheel by hand in direction it will be running to see if starts. Again BE CAREFUL
