I would contact Jim Cunningham at https://www.jimsearneye.com/. He is really good with those machines and can talk you through it. He is a distributor and has been working on them for more than 40 years. He has helped me many times over the years. He is easy to talk to and knows these machines.
Loosen the set screws that hold the turret in place then carefully pull the handle down all the way re tighten the set screws Works for me!
