Installation
Pressurizing the pedestal
1.
The Quartz Two pedestal may be pressurized from an external
pressure source or by using a portable pump. Trim weights are
provided for fine balance.
2.
Ascertain the payload to be fitted to the pedestal (payload = pan
and tilt head, camera, lens and all ancillary equipment). Referring
to the 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 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 15 bar (218 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! The column will rise rapidly if released with
no payload fitted. Do not lean over the pedestal when
releasing the safety catch.
Method Advantages Disadvantages
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.
