Swingline heavy duty staplers provide the power to staple up to 120 pages of 20-lb. paper easily and consistently. The all-metal construction of these staplers makes them an indispensible office tool. However, the way to load staples into a Swingline heavy duty stapler differs from the method for loading most other manual staplers and can cause a little confusion.

You pull up and back on the stapler head. Then pull out the spring that keeps the staples loaded. Be careful as the spring is very strong. Then put in the staples and put the spring back in behind the staples.

First, are you using the recommended staples for this stapler? Many heavy duty electric staplers don't use "standard" desk staples. Second, try unplugging the stapler, unloading the staples, and if possible, reach a couple of fingers into the stapler and try manually pushing up on the staple head to see if you can get the driver blade to come down. Does it come down smoothly, or does it seem like there is something stuck in there? If you aren't sure about disassembling the unit (my usual method-but I'd recommend having the parts diagram handy), try using a flashlight to look at the underside of the staple head, where the staples come out - can you see anything stuck in there? If so, you might be able to use a small knife blade or small dental pick to get jammed staple pieces out.

When you lift up the top of the stapler (as though you are going to put staples in), does the pusher slide freely back and forth? It might be getting stuck at some point and not pushing the staples (either due to a worn pusher spring, or friction). First (after removing the staples) try spraying some light oil on the mechanism and lifting the top part of the stapler up and down a few times and observe how easily it moves back and forth. Also, with the top open try GENTLY sliding back and forth a little - if it slides fine with no sticking, try loading staples and using stapler. If it slides ok, but doesn't quickly return to it's "normal position" when pulled so as to put tension on the spring, rhen the spring may be worn and need replacing.
