A&E/Dometic Awning Question

I have an A&E Awning (16').
Product Number 958470040
Model Number is illegible but here's what I can see 916GU1 (either 8 or 0).xxxx (can't read the last four digits.

I ordered new awning, and when my son and I took the spring loaded end off the arm, he didn't listen well and let the tube spin, then pulled out the end.

I have no idea how many turns I need to make before attaching it back to the arm. I reassembled it with 10 tuns but it's not enough.

I can remove and increase it a couple of turns at a time but I'm sure there's a recommended number of turns, and it's going to be a slow process.

Does anybody know how many turns are the recommended number?

Thanks!
