Balancing the head
Balancing the Vision 250 head achieves two objectives. Firstly, when a head is correctly balanced
the operator will need a minimum amount of even effort to move the head. Secondly, once bal-
anced, the head and its payload can be set to any tilt position and the head will maintain this po-
sition with 'hands off'.
Prior to balancing the head ensure that the pan bars and any ancillary equipment have been fitted
in order to prevent upsetting the balance once it has been achieved.
WARNING! Be prepared to prevent the head falling away suddenly.
1. Release the centre lock
clockwise until the head falls away from horizontal under the weight of the camera.
2. Release the slide plate clamp
ances horizontally. Apply the slide plate clamp (15).

4. Repeat steps 2 and 3 until perfect balance is achieved, when the camera will remain set
at any angle from +90° to –90° without falling away or springing back. Re-apply the centre

NOTE:
Maximum tilt angle is less than 90° for heavy payloads with a high C of G - see
