PIPETMAN® M

USER’S GUIDE
8. Reassemble the upper part of the tip holder and the connecting nut, and then
refit to the body of the pipette by rotating the connecting nut clockwise until it is
finger tight. Fit the O-ring (for P10M, the seal) and reassemble the lower part of
the tip holder. Refit the tip ejector.
The seals for P10M are fragile and can be used only once; therefore, after unscrewing
the lower part of the tip holder you must fit a new seal.
How to Lubricate the Piston (except P10M)
Use only Gilson lubricant (P/N: F2070902, as supplied).
Squeeze a small quantity from the tube onto a clean, lintless 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 fine film of lubricant is required (over
the entire piston).
Maintenance Operation for Multichannel Models
For multichannel models, the lower part should not be disassembled: only the push
button, the connecting nut, and the tip ejector can be replaced.
Changing the Tip Ejector
To remove the tip ejector, keep both
ejector locks depressed. Pull the tip ejector
down.
To refit the tip ejector, gently
re-insert the tip ejector vertically
into the rails of the ejector
support. Pull lightly on the tip
ejector to check the position.
Replace the Ejector Spacer
1.
Gently press the tabs from
the ejector spacer and
remove it from the tip
ejector.
2. Insert the ejector spacer and
click it to the tip ejector.
