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 pump
on page 20, or
Pressurizing from an external pressure
source
on page 21).
Place a trim weight
(28)
onto the weight tray
(25)
.
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 balance its payload such that it may be moved to any position over the full on-
shot stroke with minimum effort, and will maintain its position when the steering ring is re-
leased.
The pedestal is now ready for use.
To fit the camera and ancillary items and balance using the built-in pump, proceed as follows:
Pressurize the pedestal to balance the full payload (refer to
Pressurizing the pedestal using
the built-in pump
on page 19).
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.
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! Do NOT lean over the pedestal when releasing the safety catch.
An over pressurized pedestal may rise rapidly when the safety
catch is released, causing personal injury.
NOTE:
The Schrader valve cap
(1)
forms a primary pressure seal. Always replace the
cap and screw it down finger-tight.
