3.13 Adjusting the guide rod
The needle is pulled out of the sample vial by the upward movement of
the lift. The sample vial is not permitted to remain hanging on the needle
during this procedure. The rod that is fixed to the guide head with a
knurled screw is used to push off the vial. The vertical positioning of the
guide rod must be adjusted, depending on the height of the sample vial.
The guide rod is not permitted to obstruct the sample vial when the rack
is rotated.
