What safety precautions should I follow when soldering with the CMCE040?

Always use safety glasses, work in a well-ventilated area because flux fumes are toxic, and never leave the tool unattended — remove the battery pack, allow the tool to completely cool, and store it in a safe place when not in use. Always assume the tip is hot and return the soldering iron to its protective pen holder on the base, and never attempt to use any material other than that recommended in the manual. (Page 6)
