That sounds about right for cleaning fan.
I know I like to set the concave at 1/2 open or just a little more than 1/2 to leave a little room to open it in case a big wad gets in the rotor.
I find if the canola is really dry it is tough to get the trash out of the sample.
Sometimes it depends on the canola variety easy thresh or the pod shatter varieties that are around now might be tougher threshing.
I have some jobber concave in mine, Howard concave I think?
and they are wide slots and I leave the first concave blank in for everything.
Grain sieve usually set at around 3/16".
Had some trouble with the grain sieve not moving evenly on mine and some small rocks get jammed in the front louvers so had to pull the sieves out and do some straightening of the louvers.
