How to Die Cut 12" Finished Setting Triangles:

For best cutting results, position fabric on the lengthwise grain (straight of grain) as it goes under the roller.

Side Triangles: Cut 9-5/8" x length of fabric (LOF) strip along the selvage edge. Layer up to 6 layers of fabric. Use the Cut & Flip™ method. Start at one end of fabric by placing fabric right side up over the side triangle shapes. Place die through the cutter. Continue to cut and flip by placing fabric wrong side up and align the cut angle of fabric with the angle of blades. Continue to cut side triangles in this manner by flipping the fabric after each cut across the length of fabric. Cut 2 side triangles across the width of 40" of fabric. One yard of 40" wide fabric-cuts 8 side triangles.

Corner Triangles: Cut a 9-5/8" strip across the width of fabric. Fanfold into 9-5/8" widths. Place on selected blade and cut. Cut 4 corner triangles across the width of fabric. One yard of 40" wide fabric-cuts 8 corner triangles.

Die Tips: 
With some fabrics, after cutting, a thread or two will remain where die blades meet. Snip threads with scissors.
Blades on some dies are positioned at an angle.  Align fabric to edge of shape, not edge of die board.
Use good quality fabric to reduce fabric stretch.
It's always a good idea to test cut one shape before cutting many shapes to ensure fabric orientation is correct.
