A staple gun is very easy to operate. A staple gun is just like a regular stapler that is used to staple papers together. One difference is that a staple gun is more heavy duty and is used for home improvement projects or minor building projects. There are different ways of loading the staple gun so make sure to read the instructions thoroughly to find out to open the staple gun and load it. After the staple gun is loaded one is ready to start stapling. When ready, put the part that ejects the staples up against what you want to staple. Once it is lined up the way you want it squeeze the handle down and the staple will come out.
