WARNING
Once a day or after 20 cycles, the rotor tie-down screw must be loosened
by some turns, and the rotor must be lifted and fastened again. This
ensures a proper connection between the rotor and the motor shaft.
CAUTION
The rotor tie-down screw should only be tightened when a rotor is installed
in order to prevent the collet chuck from being expanded.
• Follow the safety instructions and hazard warnings (see chapter 3 -
"Safety")!

6.2.2.2 Installation of accessories
• Only use inserts that are suitable for the rotor (see chapter 11.1 -
"Range of accessories").
• All buckets of the swing-out rotor need to be installed when spinning.
• Always load the axial symmetrical inserts/buckets of the rotors with the
same accessories and fill to avoid imbalance.
Centrifugation with different tube sizes
Working with different tube sizes is possible. In this case, however, it is
very important that axial symmetrical inserts are identical (see figure).
