7. Mount the rotor on the motor shaft properly, check it with spinning manually.
8. Do not stop the rotor by touching with hand during the instrument is running.
9. Emergency lid open should be performed only when spinning is completely stopped.
10. Should not exceed the rated speed or specic gravity. Samples whose density is greater than 1.2g/
ml must have reduced maximum rotational speed to avoid r
otor failure.
11. The sample content should not exceed 80% of total capacity of a tube. Otherwise, it would cause
spillage of sample fluid and even the tube breakage.
12. ALWAYS load the tubes symmetrically with evenly weighted samples to avoid rotor imbalance.
If necessary, use the water blank to counterbalance the unpaired sample.
13. The operation speed should not exceed the highest value of the
individual guaranteed g-forces of
each centrifuge, rotor, bucket or adaptors and sample container, especially the guaranteed g-force of
sample container should not be neglected.
14. The rotors should be cleaned and kept dry after every use for longer life and safety.
15. ALWAYS disconnect the power supply prior to maintenance care and service to avoid electrical
shock.
16. ALWAYS use proven disinf
ection procedures after centrifuging biohazardousmaterials.
17. Should not centrifuge flammable, toxic, radioactive, explosive, or corrosive materials.
18. When it is necessary to use toxic or radioactive materials or pathogenic micro-organisms which
belong to the Risk Group II of WHO: “Laboratory Bio- safety Manual,” should follow national
regulations.
Do not place dangerous materials within 30 cm distance around the instrument, and that is also
recommended by IEC 61010-2-020.
Use the emergency lid open function only when the lid button on the control panel is dumb
under the condition of complete stop of rotor running.
Never try to open or move the instrument if it is not completely stopped.
If the power input is more than +/- 10% of the recommended voltage or uctuates frequently, it
may cause malfunction of the instrument and often result serious damage.
Install the instrument at the place without any kinds of corrosive gases.
