How to solve the problem of not being able to ignite!

1.Note: Due to airline regulations, lighters cannot be transported with gas, so all lighters do not carry gas: If you encounter a situation where the lighter cannot be ignited after filling it with gas, first please make sure that your butane bottle is in Purchase from formal channels and ensure that the gas density in the bottle meets local standards. Only regular butane bottles have the gas concentration to refill a lighter! ！！
2.After confirming that there is no problem with the butane bottle, the lighter still cannot ignite. Please check whether there is any remaining gas in the lighter. Please empty all the gas to avoid mixing of butane gases of different brands.
3.After refilling the gas, please shake the lighter up and down 3-5 times and keep it still for 3-5 minutes to keep the gas inside the lighter and the temperature of the lighter balanced.
4.If the lighter still cannot ignite, it may be that you have not cleaned the residue inside the lighter. Repeat the process of deflating and refilling again, and the lighter can be ignited. I hope this can help you solve your problem.

Safety Warnings:

1.Read and understand refilling instruction before refueling lighter. Refilling the lighter incorrectly may result in serious or fatal injury.
2.Please use authentic butane gas at 3.6-4.2 atm. Do not use bad quality.
3.Keep away from face and clothing when igniting.
4.Avoid high temperatures above 45℃/113℉ and avoid direct sunlight for a long time. 5.Do not strike or place in fire.
6.Please not ignite the lighter for long time ( more than 10 seconds ).
