Summarize this article:

Disconnect the stapler by switching the power button on the back of the compressor tank to the “off” position. Use your hand to loosen the nut on the bottom of the gun to disconnect it from the hose that attaches it to the compressor. If your trigger has a lock, be sure to activate it to prevent an accidental misfire. If the nut is stuck in place or won’t move when you try to turn it, use the appropriate-sized wrench to loosen it. Squeeze the lever at the front of the gun, and pull the rod away from the stapler to remove the magazine. Make sure you pull the follower rod all the way out to lock it into position. The follower is a rod that holds the magazine in place and makes sure it doesn’t move. Most pneumatic staple guns have a large one at the front of the gun, protruding from underneath the area where the staples fire out of the gun. Position the staples so that the legs are on either side of the rail. Use your hand to slide them up and down on the rail to ensure that they can move freely without getting caught on the rail. It’s safe to load multiple smaller rows of staples, rather than 1 large row. Unlock the follower by squeezing the lever and then releasing it. The stapler should automatically push the staples into the staple gun. If it doesn’t automatically move, give the rod small push and it should engage. Never force the rod to push up on the staples. This can cause a misfire later when you use the gun. Reattach the compressor and put on your safety goggles before turning the gun on. Then, place the front of the gun on a piece of wood pull the trigger to ensure that only 1 staple comes out of the gun at a time. It should fire smoothly with the staple laying flush against the wood. Try to use a piece that is as close to the thickness of the actual items that you are stapling together or are made from the same material. For example, if you are stapling into particle board, use scrap pieces of particle board to test the stapler.
Turn off the compressor and detach the stapler. Push on the lever at the front of the gun to disconnect the follower. Lay a strip of staples over the magazine rail with the legs facing down. Release the lever at the front of the gun to move the follower into place. Test the stapler gun by stapling into a scrap piece of wood.
