Pressurizing from an external pressure source
A pressure reducing valve must be fitted between the gas cylinder and the outlet connection of the hose. The
maximum pressure on the outlet side of the reducing valve must not exceed 14.5 bar (210 psi).
To pressurize the pedestal from an external pressure source, proceed as follows:
1. Set the column lock (27) to the ON position (see Using the column lock on page 20) and fully de-
press the moving column (4) until the column lock engages.
2. Rotate the steering ring (29) so that the pressure gauge (2) is visible through the window (remove a
trim weight (30) if necessary).
3. Remove the Schrader valve cap (1) and connect the charging line from the pressure source.

CAUTION! This pedestal must be pressurized only with clean, dry air or nitrogen to prevent inter-
nal corrosion.
