Pressurizing the pedestal from an external pressure source

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 gas 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 9.6 bar (139 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 is fitted with a pressure relief valve as a safeguard against over-
pressurization.
Do not attempt to adjust the pressure relief valve.
8 To pressurize the pedestal from an external pressure source, proceed as follows:
8.1 Fully depress the top stage
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.
8.2 Remove the Schrader valve cap
8.3 Turn on the pressure supply and slowly increase the pedestal pressure. If not already fully
extended, the top stage will rise. Shut off the supply when maximum working pressure is reached,
indicated by the leading edge of the red sector on the pressure gauge (22).
8.4 Disconnect the charging line, but do not refit the Schrader valve cap at this stage.
8.5 Install the camera mount and payload and balance the load.

Pressurizing the pedestal using the Vinten portable pump

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.
9 To pressurize the pedestal using the Vinten portable pump, proceed as follows:
9.1 Fully depress the top stage
9.2 On the pump, fold down both the feet (P.3).
9.3 Push in the handle release button
where it will lock.
9.4 Pull the hose
9.5 Position the pump between the legs, standing with both feet on the fold-down feet (P.3).
