I would'nt call myself a CD guru but have not had problems getting them set nicely and have to say I found this easier to do than with a Rekord unit.

The key is getting the right balance between the front and rear adjusting grubscrews.

If you get the rear to far in you will loose the first stage and if you get the front too far in you will loose the second stage.
I tend to start with the second grub screw slightly further in than the first then tweak them by small increments depending on the feel.

You are looking to get the sear initially sitting on the tip of the first grubscrew and then as you pull the trigger back the second grub screw engages with the sear.


The diagram in the following link shows how the two grub screws work on the sear which makes it easier to visualise:
