I had some garage door lube for overhead doors trying this. It seems to move the controls a little smother. But my question is shouldn't I be able to raise it half or a quarter of the way up and hold it there? It seems that I have to raise it all the way up or nothing
That is not correct function. Is it a new unit? If so, should be a warranty fix. Ours moves smoothly from lowest to highest, stays put when released & has an adjustable toggle stop to set a low position limit if desired when using equipment that needs to maintain a minimum height (like a rotary cutter).
