Using the DeWalt DCE530P1 cordless heat gun is easy. First, charge the 20V MAX 5.0Ah battery using the DCB115 dual - voltage charger. Once charged, insert the battery into the heat gun. You can adjust the temperature on the LCD display in 50 - degree increments according to your needs. When using it, place the gun on the built - in kickstand for stability. Remember to use the cord protector to keep the cord safe. For safety, never touch the hot nozzle. After use, let the heat gun cool down completely. To maintain it, keep it in a dry place and use the hang ring for storage. Also, check the nozzles regularly for any blockages and clean them if necessary.
