Pressurizing the pedestal from an external pressure source
To pressurize the pedestal from an external pressure source, proceed as follows:
1. Remove the Schrader valve cap (5) and connect the charging line from the pressure source.
2. Push down on the weight tray (1) against residual pressure. At the safety catches (2), push the rocker
switches to the unlocked position and leave the column fully collapsed.
3. Turn on the pressure supply and slowly increase the pedestal pressure to the required pressure. Do
not exceed the maximum working pressure, indicated by the leading edge of the red sector on the
gauge (6).
4. Disconnect the charging line, but do not refit the Schrader valve cap at this stage.
Pressurizing the pedestal using the Vinten portable pump.
WARNING! 1. This pedestal must be pressurized only with clean, dry air or nitrogen, or
the pedestal may be damaged.
2. 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 13.1 bar (190 psi).
3. Do not pressurize the pedestal beyond the maximum safe working pres-
sure indicated by the leading edge of the red sector on the gauge, to pre-
vent pedestal damage or personal injury.
4. The pedestal is fitted with a pressure relief valve as a safeguard against
over-pressurization. Do not attempt to adjust the pressure relief valve.
