My Omega Juicer 1000 shakes violently and the entire machine rotates unless I firmly hold it or turn it off. It's been in the closet for good seven years before I took it out and started using it. It's been in use for around 4 years with no problem before, but this is the first time I've seen the juicer vibrates so much that the whole machine rotates with it. Any suggestions??

Make sure the bottom of the feed chute is not damaged. If it,s chipped or scored, try filing
it down level as best you can. Then with the juicer fully assembled, unlock the set screw
on the center of the bottom and turn it clockwise until the chute contacts the blade, then
back it off a half turn and lock it down. By the way a dull worn blade will produce less
vibration. I'm assuming the lid is plastic.

THE SOLUTION TO VIBRATING. If it spins up ok, and starts vibrating suddenly as you are feeling it, here's the solution: feed it very, very, slowly. that's it. i couldn't figure mine out, then realized that if i fed it slowly, it was just fine.
