💡 Tips: 

• If you use xTool F1 Ultra with an xTool Smoke Purifier, xTool Air Assist Set, or xTool Inline Duct Fan, you need to use a smart switch to ensure successful fire extinguishing. The smart switch is not included in the package and needs to be purchased separately. If you need one, contact our after-sales services.
• F1 Ultra supports processing with its protective enclosure either open or closed. However, the fire safety set works only when you process with the protective enclosure closed.

Install the fire safety set

1. Install the tube

(1) Prepare the tube and tube adapter and insert the tube into the tube adapter.

(2) Insert one end of the tube into the tube port on the fire safety set. Then insert the other end of the tube with the adapter into the fire safety set port of F1 Ultra.

⚠️ When you install the tube, install it to the tube fitting port instead of other ports. Or it may damage the laser module.

2. Connect to the device

1. Prepare the USB cable.
   

  （1）Connect one end of the USB cable to the device port on the fire safety set, and connect the other end to the USB port on F1 Ultra.

(2) When you turn on F1 Ultra, a beep sound sounds from F1 Ultra. It means the fire safety set connects to F1 Ultra successfully.
