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/10-100μl) 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 fi rst) 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 with pistons and tip cones in the cover. Place aligning studs to the same
side when assembling the module. Close the cover with the four screws. Insert the clip 22.
12. Place the adapter tube 46 and tube 43 on the neck of the module and insert the locking

Service Instructions for Multichannel Pipette Tip Cones
To ensure even performance between all channels in a multichannel pipette, all tip cones have
to be changed at the same time, if any of them needs to be changed. Don't mix tip cones of
different packages, because one bag contains a matched set of tip cones. Place aligning studs
to the same side when assembling the module. See picture on page 71.
