- It is best to connect the cartridge while the device is off.
- Take your refillable or prefilled cartridge and connect it to the 510-threaded link.
- Turn it clockwise to tighten the connection.
- Turn the cartridge counterclockwise to loosen it and remove it.
Note: To avoid any issues when connecting the cartridge, stop tightening when you feel some resistance. Overtightening the cartridge could cause the battery to not read the cartridge. If you experience any issues, just remove and replace the cartridge.
