Installation
Pressurizing the pedestal
The pedestal may be pressurized using the built-in pump, by using a
Portable Pump or from an external pressure source.
Ascertain the payload to be fitted to the pedestal (payload = pan and
tilt head, camera, lens and all ancillary equipment). Referring to the
graph below, mark the payload on the horizontal axis then strike a
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.
!
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. Remove the payload before pumping.

WARNING!
This pedestal must be pressurized only with
clean, dry air or nitrogen. A pressure reducing valve must
be fitted to the pressure line between the as cylinder
and the outlet connection of the hose. The reducing
valve must be screwed into the gas cylinder outlet. The
maximum pressure on the outlet side of the reducing
valve must not exceed 11 bar (160 psi). 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 s fitted with a pressure relief valve
as a safeguard against over-pressurization.
Do not attempt to adjust the pressure relief valve.
!
WARNING!
A pressurized pedestal will rise rapidly when
safety catch is released. Do not release safety catch
when pedestal is pressurized and balancing load is not
installed. Always restrain the pedestal by hand pressure
on the steering ring when the safety catch is released.
!
WARNING!
Bottom stage elevation is assisted by a gas
strut. The bottom stage will rise rapidly if released with
no payload fitted. Do not lean over the pedestal when
releasing the safety catch and/or the bottom clamp.
!
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.
