When you are using a heat gun you need to be aware that the gun can reach temperatures of more than 200 degrees in less than ten seconds. Do not allow the gun or nozzle to come into contact with your skin. Keep the gun out of reach of children and pets. Do not lay the gun down on a surface while it is still hot. Use the provided hands-free stands or make sure that you have a trivet designed for high heat items close to placing the hot gun on.
