Vinten Osprey Light Pedestal Mode D'emploi page 21

English
Rotate the steering ring (3) so that the pressure gauge is visible through the viewing window (2).
WARNING!
Push down on the steering ring (3) against any residual pressure, release the safety catch (24) and
allow the column to extend fully using the steering ring (3) under hand restraint.
Apply the on shot clamp (6).
Fit the camera mount (including the pan and tilt head) to the four-bolt fixing mounting plate (27),
securing the bolts from the underside of the weight tray.
Fitting the camera
There are two different procedures for fitting the camera and ancillary items, depending on the ped-
estal pressurization method.
To fit the camera and ancillary items, and balance with an external pressure source, proceed as
follows:
Fully collapse the moving column (5) and apply the safety catch (24).
Fit the camera and all remaining ancillary items such as pan bars, prompters, lenses etc. Attaching
these items at a later stage may upset the pedestal balance.
Pressurize the pedestal to balance the full payload (refer to either 'Pressurizing the pedestal using
the Vinten portable
19).
Place a trim weight (28) onto the weight tray (25).
NOTE: To remove a trim weight (28) from the trim weight stowage (22), first rotate the trim
weight catch (23) through half a turn anti-clockwise.
Replace the trim weight catch (23) afterwards to retain remaining stowed trim weights
(22).
WARNING!
Push down on the steering ring (3) against any residual pressure and release the safety catch (24).
Set the safety catch in the horizontal position and extend the column using the steering ring (3)
under hand restraint.
If the column tends to fall, remove a trim weight (28) from the weight tray (25).
If the column rises, use the Schrader valve cap (1) to carefully reduce the pressure in steps of 0.15-
0.20 bar (2-3 psi) until the payload is correctly balanced. A correctly pressurized pedestal will bal-

1. Do NOT release the safety catch if the pedestal pressure exceeds 3.5
bar (50 psi) without a balancing load installed. Reduce as necessary,
using the Schrader valve cap
2. Do NOT lean over the pedestal. An over pressurized pedestal may rise
rapidly when the safety catch is released, causing personal injury.
