Alignment problem with used Omega D-5

A couple of months ago I purchased a used Omega D-5 enlarger. I haven't had a l ot of time to play with it yet, and I'm still accumulating the necessary accesso ries to begin printing with it. However, I do know that the silver cylinder tha t houses the condensers does not even come close to sitting flush on the negativ e stage. Can anyone tell me how fix this so I don't have major light leaks? Is there one screw or knob, or a set of screws or knobs, that will allow easy alig nment of the condenser unit? Or will I have to resort to a rubber mallet? I'd like to get printing as soon as I can.

Thanks for any insight.

Dan: The nuts under the knurled knobs where the arms that lift the head attach to the light chamber are concentric. There should be allen screws into the nuts to hold them in place. Loosen the allen screws and turn the nuts to align the light chamber head onto the negative stage. I never did get mine perfect. I got a strip of rubber sealer with stick tape attached at the home center and made a soft band around mine to stop the light.
