Maintenance

Do not use sharp tools on the rotor that could cause scratches in the rotor surface. Corrosion begins in
scratches and may open fissures in the rotor with continued use.
1
Periodically (at least monthly) inspect the rotor yoke and buckets, especially inside cavities, for
rough spots or pitting, cracks, white powder deposits—frequently aluminum oxide—or heavy
discoloration.
If any of these signs are evident, do not run the rotor.
Contact your Beckman Coulter representative for information about the Field Rotor Inspection
Program and the rotor repair center.
2
Before using the rotor, inspect the rotor drive pins to ensure that they are not damaged.
Damaged drive pins can prevent the rotor from seating properly on the centrifuge drive hub
(Avanti J series centrifuges only).
To inspect the drive pins, turn the rotor upside down and look into the drive hole in the center
of the rotor.
If the drive pins appear damaged, contact Beckman Coulter Field Service.
3
Before using the rotor tie-down knob (368410), check it for damage such as distortion, splitting,
or stripped threads.
Replace it if it is damaged.
