PIPETMAN
How to Lubricate the Piston (except U2 and U10)
Use only Gilson lubricant (ref: F2070902, as sup-
plied). Squeeze a small quantity from the tube onto
a clean, nonabrasive cloth. Use the cloth to transfer
the lubricant to the piston. Ensure that the piston is
evenly lubricated, and that you wipe away any excess
- remember only a fi ne fi lm of lubricant is required (over
the entire piston).
a Operation for Multichannel models
The two main parts of the pipette are the body
(handle) and the volumetric module (lower part).
The body contains electrical and mechanical compo-
nents that must not be in contact with liquids.
The volumetric module of the pipette contains the tip-
holders and the piston assemblies, components that
could be in contact with liquids. To service these items
you must fi rst remove the plastic ejector-cover, which
also may be cleaned or replaced.
Removing the Volumetric module
The connecting nut joins the head to the body. Unless
you need to separate the volumetric module from the
body, you should not fully undo the connecting nut. If
the connecting nut becomes loose in normal use, turn
it clockwise until fully tight. This action may be neces-
sary after adjusting the position of the head. When
you need to separate the two halves of the pipette,
proceed as follows.
1) Set the volume to zero and lock the pipette.
2) Keep the tip-ejector button depressed and grip
the ejector-clip.
3) Unlock the ejector-
clip and separate it
from the activat-
ing rod.
4) Unscrew the connecting nut.
5) Press push-button to extract the head.
