ance its payload such that it may be moved to any position over the full on-shot stroke with mini-
mum effort, and will maintain its position when the steering ring is released.
NOTE: The Schrader valve cap (1) forms a primary pressure seal. Always replace the cap and
screw it down finger-tight.
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'
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.
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-
ance its payload such that it may be moved to any position over the full on-shot stroke with mini-
mum effort, and will maintain its position when the steering ring is released.

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.
