How to fix inaccurate cuts on my Jet JWBS-12OS?

  Deanna HarrisAug 1, 2025
  If your Jet Saw does not make accurate 45 or 90 degree cuts, it could be due to a few reasons. The table stop might not be adjusted correctly; check the blade with a square and adjust the table stop accordingly. Similarly, the angle pointer might not be set accurately, so check it with a square and adjust the pointer. Finally, the miter gauge could be out of adjustment, so adjust the miter gauge as needed.

  If your Jet Saw stops or refuses to start, begin by checking all plug connections to ensure the saw is properly connected. If the connections are secure, inspect the fuse or circuit breaker. If the fuse is blown, replace it; if the circuit breaker has tripped, reset it. Finally, examine the cord for any damage. If the cord is damaged, it should be replaced.

  If your Jet Saw makes unsatisfactory cuts, several factors could be responsible. A dull blade is a common cause, so consider replacing it. Ensure the blade is mounted correctly, with the teeth facing the operator and pointing downwards. Check the blade and table for gum or pitch; if present, clean them with oven cleaner or another solvent. Finally, verify that you are using the correct blade type for the cut you are attempting.

Why does the blade wander during cut on my Jet JWBS-12OS Saw?

  Stephanie RowlandAug 16, 2025
  If the blade of your Jet Saw wanders during a cut, there are several potential causes. First, check the fence alignment with the blade and adjust if necessary. If you're using warped wood, select a different piece. An excessive feed rate can also cause wandering, so try reducing it. Ensure you are using the correct blade for the type of cut you are making, and that the blade tension is properly set according to the blade size. Lastly, check and adjust the guides.

  If your Jet Saw vibrates excessively, make sure the base is positioned on a flat, level surface. If the floor is uneven, reposition the saw. Also, check for any loose fasteners and tighten them.

Why doesn't the blade come up to speed on my Jet JWBS-12OS?

  Shannon LeeAug 26, 2025
  If the blade on your Jet Saw does not come up to speed, the extension cord may be too light or too long; replace it with a cord of adequate size and length. Another possibility is low shop voltage.
