Load the Swingline staple gun by removing the spring loaded push bar located on the back of the stapler's handle. Slide the staples into the stapler, and then replace the push bar, locking it in place.
Press the stapler against the surface that is to be stapled. You will notice that there is a line in the middle of the front of the stapler near where the staple is ejected. This line indicates the center point of the staple and allows you to safely staple around wires.
Depress the handle trigger to actuate the stapler. The trigger works by applying downward force to the handle while holding the stapler in place. You will feel the stapler kick slightly and you will hear an audible click sound when the stapler has been set in place.
