4.  ROTORS AND ACCESSORIES 

4.1  Installation Of Rotor 

Before fitting a rotor to the centrifuge ensure that the drive shaft is lightly smeared 
with petroleum jelly. Check that the rotor is clean - particularly pockets in angle 
rotors. 

Locate the rotor on the drive shaft and, ensuring that the correct spindle nut for the 
rotor in use is employed (see sections 0 & 4.5), engage and tighten the spindle nut 
finger tight. 

4.2  Removal Of Rotor 

Press Power switch off. Open the centrifuge lid. Remove all rotor accessories, i.e. 
buckets, trunnions etc. Loosen the spindle nut a few turns, grip the rotor as 
illustrated in Figure 4 and pull upwards with the fingers whilst gently rocking the 
rotor and applying downward pressure with the thumbs, to release it from the drive 
shaft. Remove the nut and lift the rotor free. 

Note: Do not attempt to loosen the rotor by tapping on the centrifuge motor 
spindle.
