SOURCE: 3rd gear spends at 1st gear speed with clicking noise

A key is most likley sheared on the center shaft.Take the gears off the center shaft.

SOURCE: A200-T Hobart Mixer 1st speed have no torque

Check the spring pin that locks the motor shaft to the main drive gear in the gear box. You should be able to turn the motor from the back at the cooling fins and watch the shaft spin in the gear, that is if the pin is sheared. That is a common problem. if you plan on keeping this machine for a while, i recomend that you spend a little more on a quality spring pin,

mechanictony-
good luck.

CE is the marking that shows its european conformant.  I think the difference is mostly in terms of the no volt interlock switch.  This means the KA style N50 bowl won't work with the CE models - too low.

Hobart mixers are NOT designed to change gears while operating. The Hobart planetary gears are like the transmission in your car but, without the clutch. Everytime you change gears while unit is running you are tearing up the brass spacers, gears & seals. Time to call a QUALIFIED service tech to come out & sell you another planetary or rebuild your old one, about $2K, Buy a Varimixer if you want to change gears while unit is running, they use belts. Another planetary premature failur cause, over loading the bowl. Batters & icings- 75% bowl capacity, Dough 65% bowl capacity.
