If the table does not start to float in a few minutes, increase the air pressure, check whether the
needle valve is open and try to adjust the position of the control lever by turning the control screw
clockwise.
Note
If the table starts oscillating after emerging, decrease the air pressure in the system and adjust the
needle valves by turning them clockwise.
2.2.3 Setting of level controls
When the system is completely floating, check the distance between the plate and the support
(see fig. 12). Dimension B must be (7 ± 1.5) mm. Set height B of every control by means of the control
screws. When all controls are set, check all three dimensions B once again and adjust them, if needed.
Fig.12. Installation of level control
Make sure that the table is floating freely on the supports. Move the table accurately from side to
side by approximately 3 mm. Perform the same operation by moving the table up and down by the same
distance. The moving of the table must be unimpeded and must not produce any noises.
Press each of the angles of the table one after another for approximately 3 mm and then release
the pressure. The table must return to the original position in approximately 3 to 4 seconds. Adjust if
necessary by means of the needle valves and pressure in the system.
