Need help with Massey 124 square baler

Helping a neighbor out with a Massey 124. He told me last time he used it he broke the needles. He put a different needle frame on it and new needles. This thing is so much different than the John Deere balers Im familiar with. I have the manual but the needle adjustment position is not very clear. The 3 hay dogs on the top are all froze up. I wonder if the needles broke due to the stuck hay dogs. Do these needle need to come way down and be closer to the knotters? Thanks
