To avoid personal injury or damage to the machine, always use a cross-cut blade to perform the shoulder cuts of the tenon.

When performing the shoulder cuts of the tenon, do not cut into the cheeks of the tenon. It will greatly reduce the strength of the joint.

NOTE: Perform your practice cuts on scrap material before cutting good wood.

1.Remove the tenoning jig from the machine.
