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 11.7 bar (170 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.

Method Advantages Disadvantages
Integrated Pump
(For units that have
this.)
• No accessory needed
• Less strokes than manual Pump
• Cannot pump with payload fitted.
Gas Bottle
• Fast
• Can add gas with payload fitted
• Not always available
• Recommended training needed for
working with compressed gas.
Manual Floor Pum
• Easy for topping up.
• Readily available
• Self pump not available for all peds.
• Physically demanding so not
recommended for payloads over 60kg.
• Some pumps cannot achieve max
pressure on some models.
