When trying to move the objective down, the knob loosens, rather than turn the gears to lower the objective. The left knob is able to lower the objective, but is EXTREMELY hard to turn.This is not a good thing. Also, the optics are STILL misaligned. See my previous problem note.

Adjusted tension knobs for smooth and easy up/down travel. Uli tested full functionality of tool. All is OK.

I'm guessing the same person who tried to change the objective also manually adjusted the "do not turn" knobs.
