Recommended Action
• Make sure that tubes or bottles are
balanced and loaded symmetrically in the
rotor as described in the applicable rotor
manual.
• With swinging bucket rotors, remove the
buckets and clean and lubricate the pivot
pin sockets where the buckets contact as
described in the applicable rotor manual.
Unlubricated pivot pin sockets can
prevent the buckets from reaching
horizontal position, which can cause
imbalance.
