Align one side of a square with the arrow mark. Draw a line through the center of the arrow. Repeat the procedure along the opposite edge of the aluminum alloy to mark the bend.Adjust Clamping Leaf DepthHold the piece of aluminum alloy vertically against the front edge of a sheet-metal brake clamping leaf. Turn the bolts located behind the clamping leaf with an adjustable wrench until the thickness of the aluminum alloy sits behind the front edge of the lower bending leaf.Bend the Aluminum AlloyPush both clamping leaf handles of the sheet-metal brake forward.
