KitchenAid mixer won't start

SOURCE: Paddle Scraping - KitchenAid Professional 600

There is an adjustment screw and a system for setting it. You can find a video of it here (or just a ton of people who know all about these mixers). I just found it while trying to troubleshoot the same problem for my wifes mixer.

The repair manual says that the mixer can make this grinding sound at slow speed, like stir or 2. This is normal, especially until it warms up. This is the sound of the gears turning at slow speed.

Why do I see oil leaking from the beater shaft of my stand mixer?
Some KitchenAid® stand mixers that are not used very often or have been tipped may experience slight oil leakage from the shaft or hub attachment. To avoid the oil leakage, KitchenAid suggests that you run the mixer weekly for short periods of time. Generally, the mixer may lose approximately X cup of oil before repair is necessary. The oil used is FDA approved and is not harmful to consume, should any get into the food that you are preparing.

DO NOT DO IT. The Hz will destroy the morotr. The transofrmer only converts the voltage. You are better off buying a 220V version.
