**Pan axis balance** Tilt the gimbal about 20 degrees from the verticality, identify if the gimbal is front heavy or back heavy. Slide the pan axis slider until the camera does not swing. Loosen the thumbscrew, then gently slide the pan axis slider backward or forward until it doesn’t swing and stay at any given position when released. Tighten the thumbscrew to make sure pan axis slider is locked in position.
