6.3 Monthly maintenance procedure
Perform the monthly maintenance procedure as follows:
1. Perform the daily and weekly maintenance procedures
(see pages 6-2 and 6-4, respectively).

replace the O-rings (see page 6-6).
6.3.1 Performing an O-ring leakage test
An O-ring leakage test is required during the monthly
maintenance procedure.
1. Switch on the BioRobot M48 and open the QIAsoft M
software (Section 5.2.1, page 5-2).
2. Select “Manual Operation/O-ring Leakage Test”.
A dialog box with instructions appears. You will need to:
- Open the workstation door
- Load the worktable according to the dialog box
(6 disposable tips and a large reagent container with
10 ml water are required)
3. Close the workstation door and click “OK”.
The pipettor head picks up the tips, aspirates the water,
and moves up.
Another dialog box with instructions appears. You will
need to:
- Open the workstation door
- Check whether the disposable tips drip within a
10 min period
4. Close the workstation door and click “OK”.
The pipettor head dispenses the water back into the large
reagent container and ejects the disposable tips into the
tip rack.
The pipettor head then moves to its home position.
5. If you observed dripping of the disposable tips, replace
the O-rings (page 6-6).
