Note: The torch is butane-free, you need to fill it with butane before using it for the first time. When you fill the torch with butane, the bottom of the torch must be upward. For the safety of transportation, we don’t equip with butane gas, you need to buy the butane gas by yourself. After fully fill the lighter with butane, you must wait about 4-5 minutes for oxygen to be fully mixed. If the torch doesn’t work and you have already wait about 4-5 minutes for oxygen to be fully mixed after filling up the butane, pls adjust the black button of the bottom of torch and make appropriate adjustment in the + direction.
