Pressurizing the pedestal
The Pro-Ped may be pressurized manually, by using the self-contained pump, or from an external
source.
A correctly pressurized pedestal will balance its payload such that it can be moved to any position
over the full on-shot stroke of the top stage, with minimum effort, and it will maintain its position
when the steering ring is released. Balance is achieved with approximately 1.5 bar pressure for
every 10 kg of load (10 psi for every 10 lb).
WARNING! This pedestal must be pressurized only with clean, dry air or
nitrogen. A pressure reducing valve must be fitted to the pres-
sure line between the gas cylinder and the outlet connection of
the hose. The reducing valve must be screwed into the gas cyl-
inder outlet. The maximum pressure on the outlet side of the
reducing valve must not exceed 9.65 bar (140 psi). Do not pres-
surize 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
WARNING! A pressurized pedestal will rise rapidly when safety catch is
released. Do not lean over the pedestal when releasing the
safety catch. Always restrain the pedestal by hand pressure on
the steering ring when the safety catch is released.
