  Kyle FordJul 31, 2025
  If your Hitachi Saw motor won't run, there are a few potential causes. First, check for a defective cord or plug and replace any defective parts. Second, the motor itself may be defective, and it is recommended to call a service center for repairs by a qualified technician. Finally, a blown overload breaker could be the issue; in this case, push the motor switch to the OFF (O) position and allow the motor to cool down.

  Breaking blades on your Hitachi Saw can be attributed to several reasons. Ensure that the blade tension is correctly adjusted. Reduce the feed rate to avoid overworking the blades. Use a narrow blade if the application requires it. Avoid applying side pressure on the blade, which can cause twisting in the wood.

  Patrick NewmanAug 15, 2025
  If the blade is not in line with the arm motion on your Hitachi Saw, it could be due to misaligned blade holders. To fix this, loosen the blade holder lock knob that secures the blade holder to the arms. Adjust the position of the blade holders to align them properly, and then retighten the blade holder lock knob.

Why does my Hitachi Saw have excessive vibration?
- D
  Diane HansenAug 22, 2025
  Excessive vibration in your Hitachi Saw can stem from several factors. Ensure the saw is properly mounted according to the mounting instructions. The mounting surface also matters; a heavier workbench reduces vibration more effectively than a lighter one. Additionally, check if the table is loose or resting against the motor, and tighten the table lock knob if needed. Lastly, confirm that the motor mounting is secure by tightening the motor mounting screw.
