Schrader valve (5).

Remove the self-adhesive safety catch warning covers (if fitted).

Push down on the weight tray (1) against residual pressure. At the safety catches (2), push the rocker switches

to the unlocked position. Allow the column to extend under hand restraint.

Exercise the column several times over its full stroke.

below approximately 3.5 bar (50 psi), indicated by the yellow segment on

the pressure gauge (6).

CAUTION! Do NOT attempt to extend the column if the pressure (6) has dropped below 3.5 bar (50

psi), or the pedestal may be damaged.
