    Yes, it will LOCK without air. Im saying you have to have air to UNLOCK the cylinder when it's time to detach the neck. That's what the air chamber on top is for.

    Make sure the safety latch pull handle on the air cylinder is in the correct position. It needs to be unlocked so the pin will drop and lock.

    This handle

    And if not the weight of the neck will push the lock pin up and sheer the safety pin off. Or so I've uh heard.
