WARNING
Blocking the air flow entering and/or exiting the T6000B rotor chamber
will cause an increase in the temperature within the rotor chamber. The
temperature increase can temporarily distort the non-metal surfaces
allowing particles to exit the rotor chamber resulting in personal injury and/
or centrifuge damage should tube breakage or rotor failure occur.

WARNING
When loading the rotor, be sure not to exceed the maximum compartment
mass of the rotor (see Table 1-1 or the individual rotor instruction manual).
If maximum compartment mass is exceeded, maximum rotor speed must be
lowered as described on page 3-6, Reducing Speed for Rotor Compartment
Loads in Excess of Design Mass. Failure to do so can cause rotor failure
which could result in personal injury and/or centrifuge damage.
CAUTION
Do not operate the centrifuge without a rotor installed and properly
balanced. Also, when installing a rotor carefully place it on the centrifuge
drive spindle. The drive can be damaged if rotors are dropped onto it.
