1. In order to ensure safety and centrifugal effect, the instrument must be placed on a solid and level table, and no objects should be placed on the engineering plastic door; the samples must be placed symmetrically, and the nuts must be tightened before starting the machine.

2. Before use, check the rotor for scratches, corrosion, etc. At the same time, check the centrifugal cup for cracks, aging, etc. If you find any doubt, stop using it immediately and contact the manufacturer; be sure to tighten the rotor before starting the operation. Tighten the nut to prevent the high-speed rotating rotor from flying out and causing an accident.

3. The speed setting should not exceed the maximum speed to ensure the safe operation of the machine.

4. If 0.00 or other numbers appear during use, the machine does not run, it should be turned off and powered off, and restarted after 10 seconds. After the set speed is displayed, press the run button again, and the machine will run as usual.

5. If the specific gravity of the separated sample exceeds 1.2 g/cm3, the maximum speed N must be corrected as follows: N=NMAX*(1.2/sample specific gravity) 1/2, NMAX=rotor limit speed.

6. Do not open the door when the machine is running or the rotor is not stopped to avoid accidents.

7. The centrifuge cup must be filled with the sample in the same amount, and the rotor should not be run in an unbalanced condition.

8. It is best not to run the centrifuge for more than 60 minutes at a time.

9. The centrifuge must be grounded reliably; when the machine is not in use, please unplug the power plug.
