Assembly:
–
Hold down the ejector.
– Position the lower part in such a way as to enable the metal pin on the ejector to enter the
corresponding opening on the lower part. The pistons of the lower parts must be in the
highest position. If the pistons are not in the highest position, they can be moved upwards
by banging the thread side firmly against a soft surface. If this proves to be unsuccessful,
the lower part is most probably dirty! The lower part must be opened and cleaned.
A detailed description of how ro do so is contained in the "Ordering information" section of
Part B of this manual.
– The magnetic coupling of the piston of the upper and lower part is indicated by a clicking
noise.
– Do not hold down the ejector any longer and push the lower part firmly onto the metal pin of
the ejector.
– Rotate the lower part counterclockwise. When the lower part is rotated, a low "click"
indicates that the safety coupling has connected and the lower part is firmly in place.
– Following reassembly, check that the ejector is functioning correctly.
– Following reassembly, trigger a motor reset by holding down the Reset key.
– Check that the dispensing function of the pipette is working correctly.
Lower part of single-channel model
Assemble in reverse order.
Check the magnetic coupling of the 5,000 µL piston.
Trigger a motor rest by holding down the Reset key.
Check that the dispensing function of the pipette is working correctly.
All volumes except 5,000 µL: For 5,000 µL:
Hold down the ejector and pull off the ejector
sleeve (1). Force may be required.
Unscrew the cylinder (2). The piston (3) is held in
place magnetically.
Pull the piston (3) out of the upper part.
Using the disassembly tool in the accessories
package (4), unscrew the cylinder bearing.
During removal, the spigots of the disassembly tool
are inserted into the openings on the cylinder
bearing.
Hold down the ejector and pull off the
ejector sleeve (1). Force may be
required.
Unscrew the lower part (2) using the
key (3).
Make sure that the piston is not
damaged.
Unscrew the piston (4). If necessary,
first loosen the piston at the upper end
using the flat-nose pliers. The piston is
moved into its lowest position
