Step 4 - Lay the blades with the staples pointing up and toward the top rail scoop. Fit the blade pins into the bead holes ensuring the tension blade is located in the holes where the tension plates are fitted. IMPORTANT: THE FACE OF THE BLADE IS THE SIDE THAT THE ROTATION BAR WILL ATTACH TO THE STAPLE. NOTE: THAT THE STAPLE IS ALMOST FLUSH WITH THIS SIDE. THIS WILL ALLOW THE ROTATION BAR TO CLEAR THE BLADE TO MAXIMUM CLOSURE. ALL BLADES MUST BE PUT IN THE SAME WAY.
