Manual mode buttons
Button 1: The pipette will move up as long as the mouse button is pressed.
Button 2: The pipette will move down as long as the mouse button is pressed. This
button does not work when the heating head is in the lowest position. In this case,
use button (4) to move the heating head a little up.
a) Move the pipette about 1 cm out of the heating head, see the following pic-

Fig. 26:
The extended pipette (3) in the position for changing the nozzle. The picture shows the pipette without the nozzle screwed
on. The transport lock is attached.
The pipette is not completely round at its lower end. It has two opposite spanner
flats for the transport lock to lock the pipette. To do so, the spanner flats must be
aligned exactly at a 90-degree angle, otherwise material damage will occur when
the transport lock is applied!
