Deere moco setup

Dealer delivered a new Deere 630 moco this week. I've never owner, nor have I ever used a mower conditioner before. Been going through the manual and making adjustments to get it ready to go to the field on Wednesday. I need help on setting up the platform float springs. As it came from the dealer, 1 side had about 10 inches of thread showing, and the other side had about 8 inches of thread showing. I don't imagine that is right, but I really don't know. Any input would be appreciated
