ejector 14 (snap fitting).
4. Turn the cylinder 13 counterclockwise and pull out the
tip cone assembly.
5. Remove the cylinder 13 by pressing the snaps fittings of
the cylinder.
5. Clean and regrease the O-ring 12 and cylinder 13.

Long-term service, multichannel pipettes
If the pipette is used daily it should be checked and lubricated every three months.
1. Place the service tool head#1 between ring 15 and ejector 23. Push the tool until the
partssnap from each other.
2. Check that the ejector lever is in up position and pull down the tip ejector part of
the module.
Place the service tool head#2 in the hole of adapter tube 46.
3. Open the upper end of the tip ejector slightly and remove the tip ejector.
4. Screw out the module of the handle.
5. Remove the clip 22.
6. Press the spring 13 and remove the locking pieces 12 from the groove. Remove the spring 13.
7. Take off the locking claws 44 and 45 and pull out the adapter tube 46 and tube 43.
8. Use a screwdriver to remove the four screws 20,21 in the module cover and lift off
the cover.
9. Remove the piston bar 16 and clean the pistons 31 and tip cones 42 with a dry nap–free cloth.
10. If needed, service the tip cones:
16channel 1-10ul: The tip cones cannot be serviced, please replace if necessary.
30-300 µl, 10-100µl & 5-50 µl: Open the tip cone by carefully releasing the cover ring 32
from its snap joint with the screwdriver. Remove all the parts from the tip cone. Clean all
the parts. If needed, replace the o-rings. Take one piston. Slide the spring 33, cover ring 32
(larger hole), spring 34,, support ring 35, (o–ring 37 bigger 5-50µl) and o–ring 36 (smaller)
onto the piston. Grease the o–ring with the lubricant provided in the pipette package. Slide
all the parts into the tip cone 30 and close the snap joint of the cover ring 32.
1–10 µl: Open the tip cone by carefully releasing the cover ring 32 from its snap joint with
the screwdriver. Remove all the parts from the tip cone. Clean all the parts. If needed,
replace the o-rings. Take one piston. Slide spring 33, cover ring 32 (larger hole), support 35,
o–ring 36 (bigger), o–ring 37 (smaller) and o–ring support 38 onto the piston. Then slide
spring 39, spring support 40 (sharp edges first) and o–ring 41 onto the o–ring sup port 38.
Grease the o–rings with the lubricant provided in the pipette package. Slide all the parts
into the tip cone 30 and close the snap joint of the cover ring 32.
11. Install the piston bar 16 with pistons and tip cones in the cover and close the cover with
the four screws 20,21. Insert the clip 22.
12. Place the adapter tube 46 and tube 43 on the neck of the module and insert the locking
claws 44 and 45.
13. Insert spring 13 and locking pieces 12 to the piston rod 16.
