Go over the owner's manual for information about safely operating your glue gun. Take note of the different components of the glue gun and how they're supposed to function. The instruction manual should be able to tell you whether your glue gun will begin heating up automatically or needs to be turned on and off, how long it typically takes to warm up, and what materials it's recommended for.  Be sure to read through the safety warnings carefully to reduce the risk of accident or injury while using the glue gun. Your manual should also specify exactly what size or type of glue stick you'll need. Before plugging in or using the glue gun, look over the body to check for cracking, splitting, chipping or any other indications of damage. Make sure you also take a look at the electrical cord to see if there’s any frayed or broken wires. It can be very dangerous to operate a glue under under these conditions. Because of their electrical and heating elements, a malfunctioning glue gun can be extremely hazardous to use. Locate an electric outlet in the wall nearest to where you’ll be working on your project. Stick the glue gun’s electric cord into the socket. The glue gun’s heating element will automatically begin to warm the glue stick inside, so don’t touch the nozzle or leave the glue gun unattended once it has been plugged in. Ensure you’re your glue gun is upright in its stand to avoid accidents.  Again, check the electrical cord for any signs of damage or deterioration before plugging it in. An cord in bad condition can present a possible fire risk. Some glue gun models are cordless, giving you more freedom to choose where and how you work. If you can't find one of these, try using an extension cord to increase your range within your work area.

Summary:
Consult the owner's manual. Inspect the glue gun for signs of damage. Plug the glue gun’s cord into an electrical outlet.
