I recently purchased a used Jet contractor saw, it worked fine for a while but now the fence is giving me problems. Whenever I try to lock it, it pushes to the left and out of square. The manual does not show any way to adjust it. Does anyone know how to adjust it?

If I cannot fix it, I'm looking at a new fence either the Accusquare or Vega. Does anyoe have experience with both? The Accusquare is a lttle cheaper but not dramatically more than the Vega.

Thanks for any thoughts and advice.
