Fasten the inflation tube according to the diagram. Pump the handle up and down to increase the air pressure inside the rocket body. The inflation tube connector has a specially-designed safety valve to release excess pressure. When air pressure inside the rocket body reaches its maximum level, the inflation tube will automatically release air through the valve.
When using for the first time, it is recommended to pump the inflator no more than 10 times to test whether the launch site is suitable.
