There are two possible adjustments, corresponding to the ##/## number on the crane adjustment screen.

The first adjustment ("30" in this photo), which you get to by selecting "ADJ ->", represents the alignment for when the crane is moving to the RIGHT, and is the amount of delay AFTER a positional switch has been triggered - which is why only a positive number is possible (0-50).

The second adjustment ("0" in this photo), accessed by "ADJ <-", represents the alignment for when the crane is moving to the LEFT. Each time you adjust the number and select "TEST", you'll notice that the crane only stops on target positions in the selected direction, then resets back to the far side.

The same delay value is used for all target positions, not each one individually, meaning you'll have to come up with a "best possible" adjustment for each direction that averages out any remaining alignment issues.

No problem! I do try to help out where I can on the games I own, and I know this adjustment in particular is very non-intuitive since there's never been any official instructions posted on how to use it. But I speak "geek", so it makes sense to me.
