What to do if the motor does not start on my Festool Kapex KS 120 Saw?
- R
  Rebecca MercadoAug 12, 2025
  If the motor of your Festool Saw does not start, begin by ensuring the cord is securely plugged into a functioning outlet. Check the outlet for power and test the circuit breaker. If you're using a Festool dust extractor, confirm the selector switch is set to "Auto". Inspect the power cord, including any extension cords, for damage. It's also possible the motor brushes are worn and require replacement.

Why are my Festool Saw cuts wavy?
- Q
  qwilkinsonAug 16, 2025
  If your Festool Saw is producing wavy cuts, avoid making plunge-then-pull type cuts. Ensure the workpiece is firmly clamped, especially for miter and bevel cuts, and maintain a constant feed rate throughout the cut. Avoid changing the feed rate during the cut. Also, inspect the saw blade for any damage, such as missing teeth or bending.

What to do about excessive tearout at the rear of the cut with my Festool Saw?
- P
  Peggy JenkinsAug 20, 2025
  If your Festool Saw is causing excessive tearout at the rear of the cut, this is often seen in plunge cuts, and less so with push cuts. Reduce your feed rate. Using a backing board or auxiliary fence can also help minimize tearout.

Why are my Festool Kapex KS 120 cuts burning?

  James LangAug 23, 2025
  If your Festool Saw is producing burning marks on the cuts, ensure you're using the correct blade for the material and that the blade is sharp and installed correctly (not turning backward). Keep the workpiece clamped to prevent movement into the blade, and consider reducing the motor speed.

  Austin BriggsAug 27, 2025
  To address excessive tearout on the top side of the cut with your Festool Saw, know that this can occur with a push cut, especially with thicker materials. Try reducing the feed rate. Also, consider whether the blade is too coarse for a crosscut operation.

  To address excessive tearout on the bottom edge of the cut with your Festool Saw, know that this can happen with plunging and/or pulling cuts. Reduce the feed rate through the cut. Using a blade that is not too coarse for a crosscut operation may also help.

What to do if the lasers do not work on my Festool Kapex KS 120?
- J
  Jimmy RobersonSep 4, 2025
  If the lasers on your Festool Saw are not working, first, be aware that they turn off automatically if the saw isn't used for a while; press the Laser On/Off button to reactivate them. Also, check that the saw is properly plugged into a working outlet and that the outlet has power, testing the circuit breaker if necessary. Ensure the selector switch is pointing to "Auto" if used with a Festool dust extractor. Inspect the power cord for damage and check the laser dust lens for excessive dust.
