When the camera mount has been secured proceed as follows:
Fit the payload to the fully-extended top stage of the pedestal, 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 three trim weights
Using the Schrader valve cap (22), carefully reduce the pressure in steps of 0.15-0.20 bar
(2-3 psi) until the payload is correctly balanced.
WARNING! The Schrader valve cap
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 released.
Fine balance may be achieved by adding or removing trim weights (13).
Disconnect the charging line, but do not refit the Schrader valve cap at this stage.
Using the Osprey Plus pedestal
Height adjustment
The column has an on-shot stroke of 510 mm (21.0 in.) and the load can be moved over this dis-
tance, in perfect balance, by raising and lowering the steering ring (23). The movement is adjust-
able for drag and this is set according to operator preference by means of the drag control
located at the top of the fixed column (12). Turn the control clockwise to increase the drag setting,
and counter-clockwise to decease it.
A clamp
(21)
can be used to hold the moving column in position if fixed height operation is re-
quired. Move the clamp lever fully to the left to apply the clamp. Move it fully to the right to release
the clamp.
Brakes
The skid is fitted with brakes on the wheels on the folding legs. The brakes are operated by press-
ing on the foot-buttons
release it.
Cable guards
The cable guards

quired. Adjustment is carried out by slackening the knobs, setting the cable guards at the required
height and re-tightening the knobs.
Steering
Directional control of the pedestal is achieved by turning the steering ring
of the column. The steering system is geared so that the skid wheels turn by the same amount as
the steering ring. This ensures, for example, that with the pedestal set to crab, turning the steering
ring by 90° will also cause the pedestal to change direction by 90°. The steering ring is fitted with
two movable indicators
will thus provide a reference point when steering.
Always replace the cap and screw it down finger-tight.
