Setup

1. Circular Saw Compatibility

The KMA4000-E guide is designed to be compatible with most left-blade and right-blade circular saws.

2. Initial Calibration and Alignment

For accurate cuts, the guide must be calibrated to your specific circular saw. This process should be performed before first use and verified before each subsequent use, especially if the retractable cutline indicators have been moved for storage.

  1. Place the Kreg KMA4000-E guide on a stable surface.
  2. Position your circular saw onto the guide, ensuring the saw's base plate rests flat against the guide's support ledge.
  3. Extend the retractable cutline indicators. Align these indicators precisely with the edges of your saw blade's kerf (the path the blade cuts).
  4. Secure the indicators in place.
  5. Perform a test cut on a scrap piece of material to confirm the accuracy of the alignment. Adjust as necessary.

  • With the other hand, operate the circular saw, guiding it along the Kreg KMA4000-E. Maintain steady pressure and a consistent feed rate.
  • The guide supports both 90-degree and 45-degree crosscuts on materials up to 8 inches wide.
