Operation
3-3
5. Make sure that the tapered sleeve is in place at the base of the centri-
fuge drive shaft before installing the rotor (see Figure 3-1). The rotor
rests on the sleeve while spinning, and will not operate properly if the
sleeve is missing. Wipe the sleeve to be sure that it is clean and dry.
Figure 3-1. Tapered Sleeve Position
!
CAUTION
Do not drop the rotor onto the drive shaft. The shaft
can be damaged if the rotor is forced sideways or
dropped onto it. Install the rotor by centering it over
the shaft and carefully lowering it straight down.
6. Install the rotor (see Figure 3-2) according to the instructions in the
appropriate rotor manual. Always run the rotor with a balanced load.
(If you are using a horizontal [swinging bucket] rotor, fill all four
positions on the yoke of a swinging bucket rotor with buckets.)
7. Attach the tie-down screw to the drive shaft by turning it to the right
(clockwise).
8. Use the T-handle wrench to tighten the tie-down screw on the shaft.
!
CAUTION
If the rotor is left in the centrifuge between runs,
make sure the rotor is seated on the drive shaft and
the tie-down screw is tight before each run. (Remove
the rotor from the centrifuge if a long period
between runs is anticipated.)
