Front derailleur - limit screws?

I need to adjust the limit screws on my 2006 XT front detailleur (top pull). However, I can't remember which screw limits High, and which screw limits Low. So can anyone help me with this:
  1. Is 1 or 2 Low? (As marked in the photo)
  2. If I want to move the derailleur away from the frame, do I turn clockwise or anti-clockwise. And is this also applicable to the High screw?

Thanks- for obvious reasons, I'd prefer not to go adjusting these at random.

Try both and which ever one moves on the inner ring is the correct one. Both are right hand thread. When you go clock wise on both screws it will move the derailluer toward the middle of the CR. Not too difficult. I would hazzard a guess that the "1" is for the inside looking at the photo and thinking how mine work. I ride campy so I am not familiar with your setup.

It's not rocket science! You can usually see from the side or bottom which screw does which.

It's sometimes hard to tell. If you can't determine by eye, shift to the small ring and keep track of how far you turn the screw you first try; if the derailleur doesn't move, go back to the original position and try the other screw. As to which way to turn, I remember it thusly: if you loosen the screw, the overall range will grow (so if you're loosening the inner limit, the derailleur will be able to move closer to the frame; and if you loosen the outer limit, the derailleur will be able to move further from the frame); if you tighten the screw, the range will decrease (reverse parenthesized description above).

Good luck!

I'm almost certain #2 is the "high" limit screw and #1 is the "low". For #2 if you want the fd to move further away from the frame, loosen it (counterclockwise) a small amount, say 1/4-turn, at a time. For #1 if you want to move the fd away from the frame, tighten (clockwise) it a small amount at a time.

I'm with hillrider on the jobs of the screws. Left = left limit Right= right limit.

I like to think of the screws as restricting. The tighter they are, the less you can go outward in that direction.
