• Hold the hand seamer by its handles firmly.
• Insert the sheet metal between the jaws at the location you want to bend or flatten.
• Squeeze the handles evenly to press the jaws together and grip the metal securely.
• Pivot or bend the seamer to shape or flatten the metal edge as needed.
• For seams, clamp along the joint and incrementally work down the length of the panel.
• Release pressure and remove the metal piece when the bend or flattening is complete.
• After use, wipe the jaws clean and store in a dry place.
