2. OPERATION
2.1 Mounting and loading angle rotor
2.1.1 Installation of rotors
Clean the drive shaft as well as the collet with a clean, grease-free piece of cloth. Place the rotor
onto the drive shaft. (see figure 9) Take care that the rotor is fully installed onto the motor shaft.
Figure 9
Hold the rotor with one hand and secure the rotor to the shaft by turning the fixing nut clockwise.
Tighten fixing nut with enclosed allan key (see figure 10)
Figure 10 Figure 11
ATTENTION: For safety always ensure that rotor fixing screw is tightened before each
run!! (see figure 10)
2.1.2 Loading angle rotors
Rotors must be load symetrically and with equal weight (see figure 12+13). The adapter may only be
load with the appropriate vessels. The weight differences between the filled vessels are as low as
possible to keep. Therefore we recommend to weighting with a balance. This reduces the wear of
drive and the acoustic operating noise.
On each rotor is designated how large the maximum load per hole is. (It is allowed to operate e.g a
12-place-rotor with 2 or 4 loaded tubes only. But the loaded borings must be opposite each other).
