I think if you look at the bracket that rises as you turn the bowl, you will see that it is supposed to "tighten up" as it lifts against the stationary "rail" that is part of the column. If it is too tight to go up all the way, see if a little candle wax or a a dop of light machine oil applied to the "rail" will overcome the excess tightness.
