several times just a few until no air bubbles are
seen in the cylinder.
2. Volume setting
Loosen the nut of the volume setting system, set
the desired volume. The upper edge of the fine ad-
justment screw shows the volume set. Fix the screw.
For calibrating purposes turn the screw of the fine
adjustment. Turn downwards to increase the volu-
me, turn upwards to decrease the volume.
Warning:
If the stopper cap is not removed when dispensing,
there may be an over-pressure in the channel
system and uncontrolled dispensing may be the
consequence.
