•
Before using the centrifuge absolutely check the rotor for firm placement.
•
When the centrifuge is running, according to EN / IEC 61010-2-020, no persons, dangerous
substances or objects may be within the safety margin of 300 mm around the centrifuge.
•
Rotors, suspensions and accessories that possess traces of corrosion or mechanical damage or
if their term of use has expired may not be used any longer.
•
The centrifuge may no longer be put into operation when the centrifuging chamber has safety-
related damages.
•
With swing-out rotors the trunnions must be regularly lubricated (Hettich Lubricating Grease No.
4051) in order to ensure consistent swinging out of the hangers.
•
For centrifuges without temperature control, when the room temperature is increased and/or if the
device is frequently used, the centrifuging chamber could be heated up. Therefore, it can't be
ruled out that the sample material might be changed due to the temperature.
•
Before the initial operation of your centrifuge you should read and pay attention to the operating
