Pressurizing the pedestal

5 The Vision Ped Plus pedestal may be pressurized using the built-in pump, by using the Vinten Portable
Pump or from an external pressure source.
6 Ascertain the payload to be fitted to the pedestal (payload = pan and tilt head, camera, lens and all
ancillary equipment). Referring to the graph
vertical line from the load figure to the balance line. At the intersecting point strike a horizontal line to the
vertical axis and read off the required gas pressure.
Pressurizing the pedestal manually
WARNING!: Do not pressurize the pedestal beyond the maximum safe working pressure
indicated by the leading edge of the red sector on the gauge. The pedestal is fitted with
a pressure relief valve as a safeguard against over- pressurization.
Do not attempt to adjust the pressure relief valve.
7 To pressurize the pedestal using the built in pump, proceed as follows:
7.1 Set the control valve
WARNING!: A pressurized pedestal will rise rapidly when safety catch is released. Do
not release safety catch when pedestal is pressurized and a balancing load is not
installed. Always restrain the pedestal by hand pressure on the steering ring when the
safety catch is released. Do not lean over the pedestal when releasing the safety catch.
7.2 Ensure that the bottom clamp
7.3 Slacken the on shot clamp (19).
7.4 Push down on the steering ring
(3). Set the safety catch in the horizontal position.
7.5 Using the steering ring, raise the top stage
lowering and raising the top stage over the upper half of its travel. When the pressure gauge
begins to register, pump the top stage over its full stroke. Stop pumping when maximum working
pressure is reached (indicated by the leading edge of the red sector on the gauge) during the pumping
stroke
WARNING!: A pressurized pedestal will rise rapidly if the control valve is set to WORK.
Do not move the control valve directly from PUMP to WORK.
7.6 Set the control valve
7.7 Set the control valve to the WORK position.
7.8 Install the camera mount and payload and balance the load as described below.
