When doing the daylight collimation recommended at site:
www.mira.org/ascc/pages/lectures/collim.htm

When looking into the front of the OTA from the correct distance, how do you know which adustment screw to turn in order to move the rings in the correct direction?

Look at the diagram here . It should help you.

Let us know how it works for you. I did my SCT collimation at night, and it took me hours! The adjustments are very fine (a little bit goes a long way). 1/4 turn will probably be too much when you're starting out. Be sure to use a high magnification eyepiece.

Hey a cool tip for fine tuning collimation in the day time.
It's about the best use for a false star. Put a small ball bearing a good distance from your scope, or if you can find a nice reflection on a power transformer pole, you can do a nice star collimation in the daylight and not have to chase the star. I used to have a ball bearing on the back fence in our yard, I'd put the scope out in the evening as the sun was going down, collimate, then it was dead on and just waiting for me to use after dark.
