    Why does my Jet JDS-12B Sander leave sanding marks on wood?
    • V
      Valerie BarronJul 30, 2025
      If your Jet Sander leaves sanding marks on the wood, make sure to keep the workpiece moving and avoid holding it still. Use a coarser grit sanding disc for stock removal and a fine grit for finish sanding. Never force the workpiece and always sand with the grain.

      If the sanding disc on your Jet Sander does not come up to speed, the extension cord may be too light or too long; replace it with an adequate size and length cord. If there's low current, contact a qualified electrician.
