White smoke on first use

This is normal; oils in the heat insulating material are vaporizing. It will stop after a few minutes of continuous use.

Tool suddenly stopped

The battery is overheated. Let the battery cool down.

Battery cannot be installed

Ensure you are using a compatible Multi Volt or BSL18xx series battery.

Before use

  • Check the tool for damage, cracks, or malformation.
  • Ensure the work area is well-ventilated.
  • Wear a dust-protection mask.
  • Check that the nozzle is at least 5 cm away from the item being heated.
  • Ensure the battery is fully charged and firmly installed.
