  If your Porter-Cable saw blade binds, jams, or burns wood, several factors could be at play. It could be due to a dull or warped blade, in which case you should replace or sharpen it. Ensure you are using the correct blade size; if not, replace it with a 10 in. (254 mm) diameter blade. Also, make sure the wood isn't moving during the cut; use a hold-down clamp to secure the workpiece to the table.

  If your Porter-Cable saw vibrates or shakes, it could be due to a saw blade that is not round, damaged, or loose. Try replacing the blade. Another potential cause is a loose arbor bolt, which you should tighten.

  If the motor of your Porter-Cable Saw doesn't start, the limit switch might have failed and needs replacement. Another cause could be worn brushes, which also need replacement. Also, check if a fuse is blown or a circuit breaker is tripped on your home panel, and verify that there is electrical power at the outlet.

  If the angle of cut isn't accurate or you cannot adjust the miter on your Porter-Cable Saw, check if the miter table is unlocked. Also, check for sawdust under the table and vacuum or blow it out, while wearing eye protection.

What to do if the brake does not stop the blade within 10 seconds on Porter-Cable PCXB115MS Saw?
- C
  Casey DavisAug 17, 2025
  If the brake on your Porter-Cable saw does not stop the blade within 10 seconds, the motor brushes may not be sealed or are lightly sticking; inspect, clean, or replace them. The motor brake could also be overheated from using a defective or wrong-size blade, or from rapid on/off cycling; use a recommended blade and allow the saw to cool down. A loose arbor bolt could also be the cause; retighten it. Also, check if the brushes are cracked or damaged and replace if needed.

  If the cutting arm on your Porter-Cable saw will not fully raise, or the blade guard won’t fully close, sawdust build-up could be the reason. Try cleaning and lubricating the moving parts.
