the seat for a smaller weight, turn the
handle contraclockwise.
Longitudinal adjustment is carried out
by means of a lever 6, which shall be

seat height it is necessary to lift the seat
up against the stop with an abrupt
movement (from the upper position of
height adjustment) and let it down to the
lower position. Adjustment of the back-
rest tilt angle is carried out by lever 5.
