Staplers are sold in fine, medium, and heavy wire variants. Fastening use includes upholstery, sheathing, palleting and packaging, roofing and flooring. The most productive staplers use air for power. Air allows the tool to be lightweight and have fast recovery for repetitive work. Problems with staplers can be related to noise, loading, safety features, and jamming. You can correct these kinds of problems through troubleshooting.
Set the air pressure on the compressor to the lowest pressure needed if the stapler is too loud. The pressure required is usually marked on the tool or on the shipping packaging.
Release the trigger and look for any safety contacts if the staples won't load. Safety features block stapler loading and can include the trigger being pressed in while loading, and a safety contact mechanism that won't let you load staples if the staple exit point has contact with anything — like the work piece. Safety switches are often labeled, but the contact system may not be.
Press the stapler against the work piece when you're ready to shoot a staple. There's likely a contact system that won't allow the staple to be released unless the exit point is firmly contacting the work piece. To test this feature, test it with the stapler pointing away from you.
Disconnect the air supply. Pull the feeder part back into the locked position and remove the good staples. Then look for a door opening around the head and open it. Look for the jammed staple and remove it with the tweezers. Then close the door and add staples. Reconnect the air and staple again. Discard the bad staple.
