Pressurising the pedestal
The pedestal may be pressurised from an external pressure source (see page 15) or by using a
portable pump (see page 15).
A correctly pressurised pedestal will balance its payload—allowing movement over the full on-
shot stroke of the moving column with minimum effort—and maintain its position when the
steering ring is released.
Ascertain the payload to be fitted to the pedestal (payload = pan and tilt head, camera, lens and
any other ancillary equipment). Referring to the balance graph, 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 pressure.
WARNING! DO NOT pressurise the pedestal beyond the maximum safe
working pressure indicated by the leading edge of the red sector on the gauge.
CAUTION! This pedestal must be pressurised with nitrogen or clean, dry air only
to prevent internal corrosion.
CAUTION! Do not reduce pedestal pressure below 3.5 bar (50 psi). This ensures
that the elevating mechanism remains in tension, preventing damage to the
pedestal.
