7. Install one main (22) and two auxiliary trim weights (21) on the weight tray (1).
Pressurizing the pedestal
The Quattro may be pressurized from an external pressure source or by using the Vinten portable pump (Part
No. 3357-3). Trim weights (22, 23) are provided for fine balance.
Ascertain the payload to be fitted to the pedestal (payload = pan and tilt head, camera, lens and all ancillary
equipment). Referring to the graph (Fig 2) on page 17, mark the payload on the horizontal axis then strike a
vertical line from the load figure to the balance line. At the intersecting point strike a horizontal line to the vertical
axis and read off the required pressure.
The pedestal should be pressurized with the column collapsed but unlocked and free to extend.
Note: The pedestal internal pressure is greatest when the column is fully collapsed.
