Fitting The Load - Vinten Quattro SL Operating Instructions Manual

Fitting the load

The Quattro pedestal has the standard four-bolt mounting plate (20) which permits the use of various
Vinten camera mounts including pan and tilt heads, Quickfix and Mitchell adapters. To fit a pan and tilt head
or an adaptor it is necessary to extend the moving column.
WARNING!
Fit the pan and tilt head or adaptor as follows:
Ensure pedestal pressure does not exceed 3.5 bar (50 psi). Reduce as necessary, using the
Schrader valve cap (16).
WARNING!
Push down on the weight tray (1) against residual pressure. At the safety catches (3), push the
rocker switches to the unlocked position. Allow the column to extend under hand restraint.
Apply the on-shot clamp (6).
Fit the pan and tilt head or adaptor and secure with the appropriate bolts.
Release the on-shot clamp (6) and lower the moving column under hand restraint. Push down on
the weight tray (1) and push the safety catch rocker switches to the locked position.
WARNING!
With the pedestal locked in the fully depressed position, fit the camera and accessories to the pan
and tilt head, ensuring that all items such as pan bars, prompters, lenses etc, are fitted. Attaching
these items at a later stage may upset the pedestal balance.
Install one main (19) and two auxiliary trim weights (2) on the weight tray (1).
A pressurized pedestal will rise rapidly when the safety catches are
released. Do not lean over the pedestal when releasing the safety catches.
Always restrain the column by hand pressure on the weight tray when the
safety catches are released.
A pressure retaining valve prevents pedestal pressure being reduced
below approximately 3.5 bar (50 psi), indicated by the yellow segment on
the pressure gauge (7).
In the event that pressure has fallen below this, pressurize the pedestal to
approximately 3.5 bar (50 psi) before attempting to extend the column.
Lock the pedestal in the fully depressed position before installing the
camera.
