7.2.4 Reassembly of tip fitting 5 and O-rings 5.1 and 5.2
- Make sure that the tip fitting has both o-rings 5.1 and 5.2 in place (Picture 8). Change o-rings
during maintenance if needed. Place the tip fitting onto the star-shaped end of tool 3 so that the
screw end is facing upwards. (Single channel pipettes 300 µl and smaller: Pull slightly the Clip
trigger 8 backwards with the other hand). Insert the screw end into the cylinder and carefully
screw in the tip fitting by turning the tool clockwise. Rotate the tool and tighten the tip fitting.
Check that there is no gap between tip fitting and cylinder (Picture 13).
Be careful not to overtighten the tip fitting. This may damage the thread in the pipette.
7.2.5 Disassembly of multichannel pipettes
1. Remove the tip fittings (Picture 8).
To remove the tip fitting place the star-shaped end of tool 3 (picture 9) into the end of the fitting.

Turn the tool counterclockwise to unscrew the tip fitting (picture 10).

Change tip fitting o-rings during maintenance if needed.
2. Press tip ejector 4.1 down (Picture 11), so that it presses tip ejector 23 down at the same time.
Manually hold the ejector cover in the down position, and let the tip ejector rise to its normal
position, so that the parts snap apart revealing a square slot. If necessary, manipulate them
gently by hand.
3. Keep the handle 42 still and insert the second end of the service tool 2 into the slot and turn
clockwise to separate the handle and the module 50. from each other. Loosen
until you can pull the parts apart.
4. Pull the holder spring 13 downwards and remove the two locking
pieces 12. Finally, remove the holder spring carefully ensuring that
the spring does not fly off.
5. Remove the two MCP adapter claws and pull the MCP adapter
46 away. Remove the MCP spring base 43 by pulling upwards.
