Rotation
The seat of the chair can be rotated left or right by 0 - 90º. Underneath the seat the lever is situated. To
lock the seat, turn the lever to the right. The chair cannot be rotated in this situation. Unscrew the lever
underneath the seat to enable the rotation right or left by 90°. A quarter turn of the lever is sufficient.
In case you turned it too wide, making it uneasy to operate, first screw home the lever and then push it
outward (see the arrow on fig. 2.6). Keep the lever meanwhile turning it to the desired position. When
you relinquish the lever it will stay in the right position. Please make sure the handle is always directed
downwards to avoid a collision.
