My DH and DD are putting my quilting frame together right now !!!!!!!!

Whoa...there's no stopping you now!!!! Congrats!

I am trying to put together the Bernina quilt frame I just bought and am having nothing but trouble. After more than three days full time, I almost have it together. Have you been able to figure out how to make the ratchets release so you can unroll the quilt? There is supposed to be a release but I can't find it.
