Make sure the area to be stapled is free of paint and clean. Remove any oils or residues from the plastic's surface.
Plug in control box and turn on. Carefully insert desired staple into one of three possible positions in the end of the stapler without depressing the power button on the handle. Once pressed to the bottom of the hole, the unit is ready for use.
Lay staple over the desired location and apply gentle pressure. Push the button on the handle, then release once the staple is at the desired depth. Allow to cool slightly. Pull back and the staple will remain in the plastic. Clip off the staple with the supplied diagonal cutter.
When clipping off the staple prongs, wear eye protection and cup your hand over the staple to prevent the clipped wire from becoming a projectile.
