1. Clean the centrifuge cavity and head, and wipe the condensate and contamination in the cavity with alcohol.

2. After use, open the door until the chamber returns to normal temperature, and then close the door cover.

3. Balance the centrifuged sample before centrifugation.

4. After centrifugation, pay attention to sterilization and disinfection.

5. If necessary, the rotor shall be pre cooled first, the maintenance and storage shall be carried out later, and the counting ring at the bottom shall be protected and cleaned carefully.

6. When the main power indicator light is not on, check whether the fuse of the indicator light and the fuse of the indoor distribution board are blown, and check whether the power line is in good contact. If the fuse is broken, replace the fuse and keep the circuit unblocked.

7. Also check the vacuum pump gauge and oil pressure indication value. If the oil pressure is too high and the main engine cannot be started, it is necessary to check whether each oil circuit is blocked, especially whether the throttling hole is dredged. If not, clean it to dredge it.

8. If the bearing is damaged or rolling is blocked, the friction resistance increases due to lack of oil in the bearing or more dust in the bearing, and the motor cannot reach the rated speed, the bearing shall be cleaned or replaced in time.

9. There is a layer of oxide on the surface of the commutator. Even if it is burned unevenly or the brush does not coincide with the outer edge of the commutator, the speed can also be reduced. The commutator and brush should be sorted to make them contact well.
