1. Press the unlocking tool as far as it will go into the base plate.
The base plate can now be detached by pulling gently at the side - at the side with the
unlocking tool inserted. This loosens the base plate on the other side. Remove the base
plate.
2. Take the inner part out of the housing case.
3. Loosen the fixing strip from the inner part. To do this, push the fixing strip away from
the inner part in the area near the three fixing strip catches on the inner part.
4. Have a close look at the channel arrangement in the inner part. Four channels are
accessible from each side. The tip cone of the channels is eccentric to the cylinder. The
channels on the opposite side are therefore positioned "mirror-inverted". Ensure that
the channels are inserted so that they are aligned in the center again during
subsequent assembly.
5. Completely press down the guiding rail for the piston rods. Press the piston rod lightly
out of the guiding rail and remove the channels.
6. Before installation, slide the piston into the cylinder. Install the channels in reverse
order in accordance with the previously mentioned instructions. After installing the
channels, carefully push the guiding rail with the piston rods upwards to ensure that
the magnetic coupling of the lower and upper part can be safely reestablished.
7. Insert the reassembled lower part into the upper part. The lower part automatically
snaps into the upper part on insertion. Make sure that the magnet on the piston
actuator in the lower part is coupled with the magnet on the spindle in the upper part.
8. Carry out a gravimetric test of the systematic and random errors.
This test ensures that no parts were confused during assembly and that the pipette has
been assembled correctly.
