Hello, there. There are a variety of things that can affect the performance of a manual staple gun--using longer staples than needed for the materials involved, not keeping the staple gun flush to the surface when firing, or not fully clearing a staple jam inside the magazine. The best way to clear Arrow's T50 staple gun is by first removing the pusher rod. Then use pliers to hold the nut while loosening the screw at the back of the tool. Once that's done, remove the screw and pull out the entire inside frame of the tool. Finally, you can use a flathead screwdriver or pliers to clear any stuck staples.
