Please read and follow the instructions on the keg box. You can also watch videos about correct set up here https://www.beerwulf.com/en-gb/blade-setup. Be aware that if the black and orange part of the nozzle are too close to each other, the nozzle might be open and the beer will flow. If you pull these sections apart, the nozzle will close and the beer will stop. This is also how your Blade operates when you pull and push the lever. We recommend checking the nozzle before installing any keg to prevent beer spillage.
