I'm afraid your question was cut off. However, based on your title, it seems like you may have been inquiring about how many times to wind the S900-34. We recommend three clockwise turns. You should feel the tension as you do this. Once you've done this for both balances and find that the window still creeps down, give them another turn. You don't want to do much more than that or you risk damaging them.
A quick learner from Scottsdale, AZ says:
Yes, my question was cut off. I need to wind the 34" series 900 green tips 15-20 times to allow tilt window to remain in place and move smoothly up-and-down. This seemed like excessive winding and I'm concerned it will adversely impact balance life. Can you comment?

That is excessive, yes. I suspect the S900-34 is the improper replacement part for your window. What is the diameter of the outer tube for your old balances? Also, what is the weight of your sash?
A quick learner says:
I matched the length (34") and tip color (green) to the originals. The sash is about 25-30 lbs. The diameter of the old balances is about 10 mm (I couldn't find my calipers, so I might be off by a mm or two).

Thank you! It sounds like the issue is the sash weight. Can you get an exact weight? A Green Tip option can only carry 14 through 26 pounds. If yours is over 26 pounds, then it would be too weak. Consider instead the Yellow Tip, which can carry 24 through 34 pounds.
