Push the rotor down until it seats.
Replace knurled retaining screw on motor shaft and hand-tighten snugly.
Insert the desired number of shields in the rotor in a balanced array.
Whenever you remove and replace a component, perform an operational
checkout to ensure that the centrifuge operates properly. Perform the following
a. Check the Speed Control.
Before operating the centrifuge, set the speed control to "0." Depending on
the rotor configuration and load, the centrifuge will rotate at less than 500 rpm
with the speed control at "0."
Set the timer.
Turn on the power.
Rotate the centrifuge at minimum speed.
(4) Gradually turn the speed control knob clockwise from "0" until the
