Multimax 22

i adjusted the main arm I loosened the 2 Allen bolts underneath adjusted so the blade is in the center of the slot then loosened the motor and turned it on as it says in the instructions tightened it down and now there is a vibration 

ot the saw is on anything on the table will run away 

what did I do wrong in my adjustments

Does it vibrate at all speeds? All scroll saws will have some vibration at varying speeds. I'd probably try going to the basics. Strip anything off that might get in the way. Put a blade in and adjust it. Turn it on slow and increase the speed. See where the vibration seems to be. Try putting the main frame back to where it was. If that fixes the problem, you're done. If not try putting the motor back to where it was. I'm assuming there are paint marks to go by. I'm thinking that the motor is the problem. It has to run true. 

Also, there is a Brit on Facebook who is an expert on restoring Hegners. He might be able to help. He responds fast to posts. I can't recall his site name but I'll try to find it. 

Edit: Found it, he goes by "Hegner, A Saw Subject". He buys, restores and sells Hegner saws.

The very first thing when a scrollsaw vibrates is check the legs of the stand. Make sure they are sitting flush on solid ground. Any bit of tilting can throw vibration into the factor. Same if a saw sits on a bench. The foundation under it must be sound and solid. Next make sure all bolts are tight. Moving the arms and table may have put it out of balance. Those saws are tuned before they leave the factory. May have to call Hegner to get some pro help. Good luck.

As JT said, all legs touching the ground firmly; bolted down if possible.  3 legs works far better than 4.  

Also, be sure there is no flex anywhere in your stand and that it is plenty heavy.  

I struggled to get my Hegner 22VS to run smooth.  Accidentally discovered the trick for my situation this year.  I had built a butcher block type table to mount it to and attached that to a 2x4 framed cabinet.  I could park a truck on this stand it is so solid and heavy.  Then for convenience it sat on a Harbor Freight moving scooter.  No matter what I did it would vibrate at the speeds I wanted to run.  This fall I set it directly on the floor.  Vibrations are gone.  No clue why.  

Keep the arm bushings lubed too.  It seemed to help with my fight.  

Best of luck!
