Before inflation, use a small tool to hold the inflation core, completely discharge the residual gas inside, and eliminate the pressure in the lighter gas tank;
Press the outlet of the gas tank vertically downward for about 5 seconds each time, two or three times.
After inflation, please wait for about 5 minutes before using. If the ignition still fails after 5 minutes, please turn up the regulating valve. (Note the+- direction).
